Details should understand when patching refractory brick

     Refractory brick most are used in the kiln, but for a long time are damaged, we need to replace it, and the change of refractory brick is not easy in the kiln, the need to pay attention to detail is very much, so today let technical personnel in Changing to tell you dig the refractory bricks need to understand knowledge.

    First, when we replace the refractory brick new needs to the refractory brick broken down, and then replaced with new, need to pay attention to in the refractory brick we had broken, to start from the weakest, then one brick at a time to take, but do not continuously down, when refractory brick with broken to the attention of the kiln body around have loose phenomenon, if have loose would stop or the brick back, when not loose and take, this is what we in the patch kiln refractory brick inside need to pay attention to details.

The second is when we place patching refractory brick alkaline, if the situation is not very good, we can consider replacing the whole site from tire, and so as to avoid distorting phenomenon appears in the repair time.

     The content of the, need to know the details of when patching refractory brick you have some understanding of it, if you want advice on refractory brick more knowledge can consult us

How is the castable development prospect

    For some want to do industry castable but very hesitant people, who are considering how is industry castable prospects, technical staff of Xinmi Changxing today to give you an answer.

    In fact, choose industry castable shows that you are still very eyes, because the development prospect of the castable is very broad, whether can use castable in what place, so it can be said is the choice of castable is not wrong; there is the prospect of castable is good but also because of their condition outstanding, first of all the first is the castable high-temperature considerable, so whatever is great in the iron and steel factory or in the furnace of the demand, and the use of many places, development benefit will be relatively good many; and then pouring material and long service life, unlike the ordinary refractory material, we did not take long for the index has declined step by step, to bring certain influence to our production and work efficiency, problems like this we can choose castable. But like the petrochemical industry are large enterprises to use castable, the future development has brought great benefits, so in general the development prospects of castables is very good.

    The content of the development prospects of castable maybe you have some understanding of it, if you want to ask more about castable knowledge can consult us freely.

Refractory brick grinder designing needs to follow the rules

Refractorybrick in the production process cannot do without the help of the size and quality of mold, mold determines the quality of refractory brick molding, the following is the principle of making refractory brick shaping mould:

1, the form must be smooth surface, smooth, and have higher hardness.

2, installation of formwork should taper, under the mouth small, big, catchy symmetry, and to ensure that qualified size refractory brick. Taper model after installation is generally 5/1000.

3, uneven surface should be made into a hopper.

4, as far as possible to make the maximum area of the refractory brick as the compression face.

Ditch edge at 5, within the model with radian, template at a corner with L - 2 mm arc.

6, in the event of a mould bottom protruding part, try to make the survival of wedge.

7, the scaling length ratio. The general is according to different kind of brick and clay, is determined by the actual test. At present, China's production of brick, scaling rate is generally 3-4%; length ratio put clay brick for 1-2.5%.

8, thick skin: refractory brick more than 150 mm, should consider two pressures.

Through the above simple introduction I hope can help to you, we produced the high quality and low price firebrick , please contact us if you have the need.

Monoblock Stopper

According to the quality of the materials, the monoblock stopper of our company can be classified into aluminum carbon, aluminum-zirconium carbon and aluminum-magnesia carbon. This product enjoys performances including favorable slag resistance, strong fracture resistance at normal temperature, fine liquid steel resistance and washing erosion, to ensure reliability in the course of product usage.

Cause and prevention method of refractory brick burst

Firebrick occurs burst when experiencing thermal shock, the simple reason there is expansion and contraction, and the reason is prone to burst firebrick type as follows:

1.The refractory brick is composed of mineral quartz, tridymite, cristobalite composition, the temperature change is accompanied by a transformation of the crystalline form of the quartz, resulting mutations volume, thermal shock so that the refractory bricks easily burst.

Magnesia or magnesia-chrome brick, due to the thermal expansion coefficient, thermal firebrick burst prevention

1.The use of insulating firebrick, insulating firebrick with insulation due to the role of firebrick inside low stability, not easy to burst.

2.To avoid thermal shock, slow heating and cooling can be effective in preventing refractory bricks burst.

3.Select the heat transfer coefficient is relatively high, toughness good bricks, can reduce the probability of bursting.

Low Carbon Brick,Carbon Brick,Magnesia Brick,Firebrick,Fire Brick,Refractory Brick

Low Carbon Brick

Low carbon magnesia carbon brick using with crystal magnesite, fused corundum, fused spinel, high purity and ultrafine graphite and nano composite antioxidant as raw materials, which are used for ladle slag line. Low carbon and carbon-free corundum spinel bricks are used for ladle lining and bottom. It can realize ladle low carbon and carbon-free to meet the needs of high grade and ultra-clean steel. The products are characterized by corrosion resistance, penetration resistance, erosion resistance, spalling resistance and good integrity, to meet the need of complete refining ladle. It is the leading level in the domestic.
