Castable, also known as refractory castable, is the most common refractory material in unshaped refractory materials. It needs to be poured for construction, so it is called refractories castable. It is a granular and powdery material made of refractory materials and a certain amount of binder. fluidity. It is a consumable for industrial furnaces. It is widely used to construct various heating furnace linings and other integral structures. The main uses are as follows: pouring molding of key parts of the furnace body, such as the furnace door frame, near the feeding port.

What are the types of castables？

1. According to chemical indicators, it is divided into acid-resistant castables, neutral castables and alkali-resistant castables.

2. Divided by density: light castable and heavy castable

3. According to the raw materials, it is divided into: clay castable, high alumina castable, siliceous castable, mullite castable, corundum castable, magnesia castable, siliceous castable, silicon carbide castable, etc.

4. According to the characteristics of fire resistance, it is divided into: high-strength wear-resistant castable, high-temperature resistant castable, low-ash cement castable, steel fiber castable, acid-resistant and heat-resistant castable, slag-resistant and wear-resistant castable, etc.

Refractory castables with different characteristics are used in different industrial kilns.

How does a castable manufacturer produce castables?

Refractory castable production process: The refractory raw material particles or blocks are relatively large and need to be crushed, crushed, sieved, and ground; then added to the batching scale according to the formula to add admixtures, powdery binders, etc. to be pre-mixed, so it is called Pre-mixed powder. Finally, the powder package is sealed after being evenly stirred by a mixer and sampled for inspection. Each batch of castables produced will undergo rigorous performance testing and chemical inspection. After passing the inspection, a formal quality warranty and construction technical requirements specification will be issued to customers.

 Why are Chinese castables low in price and good in quality?

China is a large raw material supply country, with abundant refractory raw materials, no need to rely on imports, saving freight and low cost.

We are the source factory manufacturer, we produce and export ourselves, and there is no middleman to make the difference. Our company invests mainly in the control of product quality without extra costs.

Why is Yuying castables worthy of your trust?
