Refractory brick classification for cement kiln

1, high aluminum brick: Al2O3 content more than 75, refractory degrees higher than clay brick, acid and alkali resistance erosion resistance, suitable for cement kiln etc., the use of long life and high price of refractory brick.
2, the dolomite brick: Hang kiln skin performance is good, good erosion resistance, but there are brick in f-CaO number, hydrated, difficult to transport and storage, production with less.
3, magnesia chrome brick: Hang kiln skin good, used for firing zone, the disadvantage is the thermal shock performance is poor, plus six price Cr is highly toxic, the production and use of magnesite chrome bricks in countries gradually reduced, now with this brick production unit as soon as possible to find alternatives.
4, spinel brick: mainly used for transition zone, earthquake good performance, anti good reducibility, but refractoriness slightly worse.
5, anti flaking brick: this brick contains a small amount of ZrO, martensite phase transformation occurred during the heating process of the formation of fine crack, with strong alkali resistance, spalling resistance and slag resistance of good.

Correct methods to select good quality refractories with low cost



      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 production, 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. For how to choose the right refractory is introduced in following four aspects:
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.
We Xinmi Changxin refractories plant convenient transportation, rich in resources, is the base for the production of refractory materials ideal, high-quality refractory raw materials base believe refractory products can produce satisfactory.

Magnesia Carbon Brick


Introduction:
Magnesia carbon brick series used for the electric furnace are made by adoption of fused magnetite, high-purity magnesium sand and graphite as principal raw material, through high-pressure molding and low-temperature treatment. This product is mainly used for electric furnace lining, which enjoys advantages including high temperature resistance strength, corrosion and spalling resistance. According to the smelting conditions and the kind of smelting steel, different brands magnesia carbon bricks are available. Magnesia-carbon bricks are resin bonded bricks containing high-purity fused and or sintered magnesia and flake graphite as their main ingredients.

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.

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.

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.
