Product Description



Manufacturing with Good Quality Silicon Carbide



They are mainly used in four big application fields: functional ceramics,refractories, abrasives and metallurgical raw materials .

 SiC is suitable for cupola and electric furnace. 

As deoxidizer, it is widely used in foundry and steel industry. It can rapidly increase the temperature of molten steel, shorten smelting time, at the same time, it also can play deoxidizing, increasing carbon and silicon, heating up role. It can improve the quality of steel.



1. Increasing carbon and silicon, reducing the consumption of 

carburant,ferrosilicon and other alloy, saving the cost of per ton steel.

2. AS SiC is oxidized, it can release a large number of heat energy,  reduce the cost of electric, lower the cost of production.

Q:Does the aluminum silicate fiber can be used outdoors? If not, what other refractories can be used outdoors?
Q:How to divide fire rating of decorating materials ?
I am very happy to answer this question for you. It can be divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability. I hope my answer is helpful to you, thank you.
Q:What are the main components of refractory cement?
SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
Q:what kind of fireproof materials is used for high rise buildings?
Recommended thickness of 1mm or more # 304 stainless steel, refractory, corrosion-resistant, easy to clean. closed balcony of high rise buildings use thickened manganese, aluminum profiles. You can also use plastic steel window, solid wooden windows. Mg-Mn alloys have excellent weldability and corrosion resistance, unstressed corrosion tendency. Mechanical properties are not good enough, the ultimate strength of 210 ~ 280MPa.
Q:Who knows the fire endurance of B-level fireproof doors and windows?
B-grade fireproof windows refer to those fireproof windows whose fire retardant limit is not less than 1 hour. Technical requirements: I. Materials and Accessories (1) Window frame should have a certain strength to ensure the integrity and stability of the steel frame or the wood frame. (2) Steel frame and mound layer can employ galvanized steel sheet or stainless steel plate. Its selection criteria should be in line with the stipulation of the Article 5.1 of GB12955 "General Technical Requirements of Steel Fireproof Doors". (3) The selection standard of wood frame and mound layer should be in line with the provision of Article 5.1.1 of GB14101 "General Technical Requirements of Wooden Fireproof Doors". (4) Filling materials inside steel frame and wood frame should be non-combustible materials.
Q:What are the models of bauxite with high alumina?
China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
Q:How to count the construction costs of refractories?
In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
Q:What are the components of refractory clay?
The major raw material are bauxite, magnesite, silica, etc. It is easy to combine, high temperature resistant, corrosion resistant and has other advantages. It can be applied for refractory bricks in a variety of masonry.
Q:What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
Q:What is the particle size of boron carbide for refractories?
2 floor is right, support, learning! But what do you mean by boron carbide (d90=36.5, m)?
