Sunrise refractory castable, also known as refractory castable, is a kind of granulated and powdery material made of refractory material with a certain amount of binder. It has high fluidity and is formed by casting.
 
Compared with other amorphous refractories, the binder and moisture content are higher, and the fluidity is better. Therefore, the castable has a wide application range, and the materials and binders can be selected according to the use conditions. It can be directly cast into a lining, or it can be made into a precast block by pouring or compacting.
Sunrise refractory high-strength wear resistant castable is an amorphous refractory material made of aggregate and powder plus binder. The castable has high alumina castable, corundum castable, silicon carbide castable and clay castable according to different materials. , siliceous castables, magnesium castables, etc. According to the main purpose, it is divided into anti-seepage castable and thermal insulation castable. The production cycle of refractory castables is generally shorter than that of low-fire bricks of the same material, so the sales of refractory castables are very large. The castables have high requirements on the formulation, the particle grading must be reasonable, and the influence of the type and amount of the admixture on the castable is also very obvious. The construction and oven of the castable should be carried out in strict accordance with the requirements, so as to ensure the service life of the castable. Due to a series of objective reasons such as the construction environment and the progress of the project, some additives or other materials may be added to the castable to meet the requirements. For example, a certain amount of low-heat steel fiber may be added to the castable to enhance the strength of the castable. Add some coagulant to speed up the initial setting time of the castable. The special use environment makes the castables have to adjust the proportion to improve the performance of the castables, such as low cement castables for heating furnaces, because the increase of cement quantity will degrade the performance of castables, in order to meet the conditions of use, The amount of cement is not reduced, and the strength of the castable is increased by adding an improved material to avoid the influence of the decrease in the amount of cement on the strength. In the electrolytic aluminum and aluminum alloy industries, castables need to be added with some materials resistant to aluminum water to prolong the use of castables. After some materials such as nitrides are added to the castables, the non-stick aluminum properties of the castables are greatly improved.
Sunrise refractory low-cement refractory castables are mainly used in metallurgy, electric power, petroleum, chemical and various silicate furnaces, such as some components of refining equipment outside the furnace, refining bags outside the furnace, and processing molten steel and molten iron. Spray gun, electric furnace top lining, heating furnace soaking furnace, annealing furnace lining, tundish lining, tapping tank, high temperature burner and blast furnace tapping groove cover, ladle lining, etc.
 
Sunrise refractory high-strength wear-resistant castable has high strength, good high temperature performance, stable volume, small thermal conductivity, strong resistance to slag penetration, erosion resistance, convenient construction, strong furnace structure and other characteristics. An anti-wear material used in bed boilers can greatly improve boiler run time compared to conventional castables.
 
Factory direct selling price, can be customized to a variety of specifications, quality and cheap, large quantity and more favorable. Sunrise refractory sincerely look forward to working with you!
