Details of knowledge should pay attention to the selection of refractory materials

     Selection of refractory materials needs to pay attention to the details of knowledge. High temperature industrial development cannot do without refractory material function, especially in the iron and steel, nonferrous metals, glass, ceramics, cement, petrochemical, machinery, boilers, light industry, electric power, military and other fields, is the basic material of an operation and technology industrial production, with each field of industry continue to increase, the demand quantity of refractory products is also gradually increasing, which requires every manufacturer increase the output, while at the same time ensuring the production quality of the product is the most critical, it is also the fundamental in all areas of normal operation. How to choose the appropriate refractory should be for the majority of the use of units? This is we have been very concerned about the problem; here we take a look at it.

1 according to the structure, working characteristics and motion conditions of the furnace and the analysis of material damage reasons, in order to choose the appropriate refractory. Accurate understanding and grasp the temperature changes of all parts of the material, carefully observe the material to prevent by all kinds of destructive effects, such as: high temperature molten metal erosion.

2 familiar with the material chemical composition and physical, work performance, so as to give full play to the characteristics of material.

3 so that all parts of the furnace material reasonable match, in order to avoid the mutual damage at the same time between material, but also take measures to ensure that the service life of the whole.

4 basic principles in satisfying the conditions above, to solve the resource and cost as much as possible. Can choose prices and transport costs low material, at the same time, vigorously develop the recycling, reduce the cost of.

The four question above is each big unit using refractory selection needs to be considered, which can ensure the quality of products and reduce the cost, is a very good selection principle.

Silicon Carbide,Silicon Carbide Brick,Refractory Material,Refractory Product,Refractory Mortar

Silicon Carbide

silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond .Mechanical intensity of it is higher than fused alumina. It is britte and sharp and has electrical and heat conductivity in some degree. The abrasives made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc.It is also broadly used as refractory material and metallurgical additive.

Modulation principle of slurry used for refractory brick

 Brickwork with refractory slurry should follow the following principles:
    (1) to deal with all kinds of refractory slurry pre experiment and pre laying brick front, confirm the bonding time, different mud initial setting time, consistency and water;
    (2) Modulation of different mud to use different instruments, and timely cleaning;
    (3) Modulation is not homogeneous slurry to use clean water, water should be accurate weighing, blending uniformly, adjusted with the use. Have good hydraulicity and modulation of hard mud shall not add water use, has the initial setting of mud may not continue to use the;
    (4) Modulation with phosphate mud to ensure material time trapped provisions, with the use of post set, well modulated mud arbitrarily diluted with water. This kind of mud for corrosive shall not be in direct contact with the metal shell.

    We take the zero defect management idea, through the production process from beginning to end. All the time since, in the pursuit of perfect quality at the same time, also constantly improve the service system, concerned about each of your needs, to provide professional sales and technical service for you.

Using requirements of boiler with refractory material

     Boiler burner band main properties of refractory material should have included slag resistance, high strength, wear resistance, thermal stability, thermal conductivity and other properties. The traditional refractory belt mainly used chrome refractory ramming material, but because of the domestic high quality chrome resource scarcity, therefore is the main use of silicon carbide ramming material, silicon carbide high alumina coating material, high aluminum phosphate can be plastic, high temperature expansion plastic.

Of which the first two kinds of materials of high prices, but the long service life, good performance, and then two kinds of material price is low, but performance in general, and short service life. Therefore in the cyclone furnace liquid slag furnace and should not be used in high phosphate refractory plastic or ramming material, to avoid peeling or cracks in use in the production, so as to enhance the slag resistance of material and reduce the repair frequency.

High-temperature micro expansion refractory plastic and super 3000 water clay refractory performance fairly, has shown some advantages in the application to the wall pipe and boiler furnace top. But this kind of material in its solidification time is long, easy to dry shrinkage crack, thus for the construction and maintenance of a great deal of trouble. At the same time the supplier quality there is a certain fluctuation, sometimes refractoriness and normal temperature strength of less than 1580 degrees and 981N/cm2.

Refractory materials commonly used in neutral and alkaline induction furnace

Neutral and alkaline lining is used only for induction furnace capacity of less than 10 tons. The cost is much higher than the acidic lining lining, so must meet the smelting efficiency is very high to the economy. Neutral and alkali furnace refractory material is sexy:

(1) Sintered magnesia. The erosion of the sintered magnesia against molten metal and slag is very good, and high refractoriness, disadvantage is the contraction occurred two times during sintering, resulting in cracks and voids. Risk also contained the fully sintered, affect the elastic. Cause of crack;

(2) Fused magnesia. Electric volume stability of fused magnesia is good, but expensive than sintered magnesia.

(3) Magnesia - alumina - spinel. Magnesia - alumina - spinel due to volume expansion appears in the formation of spinel, so as to compensate the shrinkage of magnesia. Degree of expansion by the number and shape of corundum and mineralizing agent control. (4) Chrome magnesia - alumina - spinel. Chrome magnesia - alumina - spinel besides the advantages of the spinel, also has good thermal stability;

(5) The calcium oxide crystallization. Calcium oxide crystallization created favorable conditions for dephosphorization and desulfurization, but easy to crack, and cooling easily. In addition, the stove temperature will absorb moisture, so it is in danger of hydration. The crystallization of calcium oxide lining can neither be ramming material, also can not be made into bricks used in induction furnace.

Refractory castable flowability

        We know that there is refractoriness refractory castable, but what is its fluidity is it? This point will we do not know, because a lot of people for refractorycastable fluidity is not particularly understand, so today let technicians Changxing new secret to tell you: the flow of knowledge refractory castable degree.

We all know that is not the same refractory castable construction, but only that they have the same fluidity, but there will be different refractory castable performance problems at the same fluidity of the situation, and these are associated with castable construction method, temperature and material used so inseparable bond, so it proved castable has a certain fluidity. But how do we find the fluidity of refractory castable and its determination it? Then we need to use the fluidity of the measurement equipment, and is a 760mm diameter table of jump. The trial of a high 127mm, catchy diameter 171mm, 254mm outlet diameter truncated cones placed in the center jump table, mixing the two layers tamping castable placed the barrel, then remove the cone to a beat rate of 15 times per second, so that the desktop castable expansion amount of the expanded diameter D (mm). The formula to calculate the degree of liquidity is: F1: F1 = (D-254) / 254 * 100%. After these processes is measured out refractory castable degree of liquidity.

Comprehensive above described, the fluidity of refractory castable what knowledge you have some understanding of it, if you want to consult more knowledge about refractory castable can consult us.

Matters needing attention during the construction of the castable refractory

Refractory castable is a widely used refractory products, it is there for many industries are very popular, because often used to this kind of refractory products, so today I will introduce the construction of refractory castable, should pay attention to the related matters.

The first step in the pre construction should be strictly examined, including: (1) to form a clear structure of castable refractory equipment is, and it will be clean. (2) to know have the process holes (3) construction require the use of the equipment must be in good condition, so we can ensure that the work can be carried out smoothly, (4) to know how is refractory castable packaging and delivery date, check whether the product failure. Using the second step is the construction of templates you can use steel or hard wood. But must ensure that the template has a very good rigidity, also is the strength to be good enough, so as to ensure not to use when running, will not shift, leakage. The use of wood template you must brush on a layer of waterproof paint, but steel template will be used in addition to mold agent, want to save template words, must be cleaned before use.

The final point to note is the lining refractory castable, stirring time, time can not be less than 5 minutes, can not use ordinary mixer, and to the use of forced mixer, must first dry mixed before mixing, then adding 80% solvent mixing, slowly stirring to obtain suitable work consistency. If there is something still unknown that you can contact us freely.

Design of AOD Molten Pool

    For the design of AOD molten pool, it is better to choose flat molten pool. The flat kind has been proved to be the best one according to the past experience.

   One special feature of the flat molten pool is that its furnace bottom conic section is short and its ratio of molten pool diameter to height is big, D/H is not less than 2.2, while in conventional AOD design, D/H is always no more than 2.2. It is also proved that relatively flatter molten pool has great effect on metallurgical properties of the furnace, especially for its decarbonization function. What’s more, it has the following four advantages for using flat molten pool.

1. It can reduce CO partial pressure in bubble surface, speed up decarbonization and improve the efficiency by 15%.

2. Shorter blowing and converting time.

3. Lesser consumption of reductive silicon.

4. Lower refractories cost due to no backpack.
