Haicheng Haoyang Refractory Materials Co., Ltd. is one of the large-scale enterprises specializing in the production of refractory materials in Liaoning Province.

Nowadays, society is developing rapidly, and people's safety awareness is constantly improving. What is the disaster that people are most afraid of in our lives? It is undoubtedly fire. In order to avoid fires, new materials have been added in many places. Castable is a new type of refractory material, and its main feature is high fluidity. Lightweight thermal insulation refractory castable is composed of high-quality, high-strength materials as aggregates, ultra-fine powder, and composite additives. Therefore, refractory materials have a wide range of applications and can be selected according to the materials used and binders. They can be directly poured into linings for use, or made into prefabricated blocks by pouring or ramming methods, etc. How do we choose good refractory castables?

The following points should be noted when choosing:

1. Wear resistance: Castables should be resistant to impact and friction, etc.

2. Thermal stress resistance: If the material has a relatively high moisture content, it is easy to match and not easy to cause thermal stress fatigue.

3. High-temperature performance: Good high-temperature performance. Dehydration shrinkage and stress release of steel structures are prone to large cracks, and the requirements for oven drying are high.

4. Appearance after oven drying: There are cracks. According to specifications, cracks of 5mm are a normal phenomenon; if they exceed this, filling and repair treatment is required, and there will be cracks in the appearance.

5. Stability during heating operation.

The production process is simple, labor-saving and energy-saving, with high construction efficiency and good quality. Refractory castable is an unshaped refractory material with a large dosage and a wide range of applications in furnace construction projects. It can not only enhance toughness but also help improve its thermal insulation performance.
