1.Refractory castable is a refractory material that does not need to be shaped and has good fluidity after being fired and stirred. Its structure is made up of aggregates, powders, and glues according to the process ratio, which can replace products with complex shapes, high degree of abnormity, and wide area.
2.Refractory castables have the advantages of convenient construction, shortening the construction period and reducing labor intensity.
3. Lightweight refractory castables are suitable for all kinds of furnace lining heat insulation layer, float glass furnace flue sealing castables.
4. Heavy refractory castables are mainly used as lining and sealing materials for thermal equipment of industrial kilns.
Four advantages of Zhiyao refractory castables:
1.Refractory casting has the characteristics of low thermal conductivity, good appearance characteristics, and good casting integrity.
2. The characteristics of refractory castables are to increase the medium temperature strength and load temperature, reduce the thermal conductivity, and have good thermal stability.
3. The air-tightness of refractory castables is also better than that of brick furnaces, which saves the cost of a furnace repair.
4. The ratio is reasonable to meet the customized needs of customers.
High-aluminum castable is a refractory castable made of high-aluminum raw materials like aggregate and powder and added with binders and additives. High-aluminum wear-resistant castables have high mechanical strength and good thermal shock and abrasion resistance. They are mainly used as linings for boilers, blast furnace hot blast stoves, ceramic kilns, and other kilns.
The difference from other unshaped refractories is that high-aluminum wear-resistant castables have a certain setting and hardening time after construction. Therefore, after the castables are formed, a certain period of curing is required before they can be demolded, and then natural curing after appropriate time Can be put into baking use. High-alumina castables have a particularly wide range of applications due to their excellent performance.
