What is special about clay castables?

1. مقاومة درجات الحرارة العالية

Clay castables can easily withstand high temperatures above 1600°C, making them an ideal choice for high temperature industries such as metallurgy and casting.

2. Good fluidity

It has excellent fluidity and can be easily poured into every corner of complex molds, ensuring a smooth surface after molding and reducing defects.

3. Strong wear resistance

Under high temperature and high pressure environments, clay castables exhibit excellent wear resistance, extend the service life of equipment, and reduce maintenance costs.

4. مقاومة الصدمات الحرارية

Even if it undergoes drastic temperature changes, it is not easy to crack, and is particularly suitable for industrial scenarios with frequent heating and cooling.

5. Environmentally friendly and safe

Using environmentally friendly raw materials, it is non-toxic and harmless during production and use, and meets the requirements of green manufacturing.

6. Flexible application

In addition to pouring, it can also be used by spraying, patching, إلخ., to adapt to different industrial needs and has strong versatility.

The difference between clay castables and other castables

1. Composition difference

• الطين قابل للصب: refractory clay is the main raw material, Al2O2 content is low (usually 30-45%), and the cost is low.
• High-aluminum castable: mainly high-aluminum bauxite or corundum, high Al2O2 content (50-90%), better refractory performance.
• Corundum castable: mainly corundum, Al2O2 content ≥90%, excellent high temperature resistance and erosion resistance.
• Mullite castable: mainly mullite, Al2O2 content 60-75%, excellent thermal shock resistance and high temperature strength.

2. Application difference

• الطين قابل للصب: suitable for medium and low temperature kiln lining, hot air duct, flue, إلخ., low cost, economical and practical.
• High-aluminum castable: used for high temperature kilns, boiler linings, أفران التدفئة, إلخ., with better high temperature resistance.
• Corundum castable: used for high temperature furnace lining, ladle, فرن كهربائي, إلخ., with excellent corrosion resistance and high temperature resistance.
• Mullite castable: used for high temperature kiln furniture, hot air furnace, ceramic kiln, إلخ., with excellent thermal shock resistance.

مقارنة شاملة

• الطين قابل للصب: suitable for medium and low temperature and low corrosion environment, economical and practical.
• Other castables: suitable for high temperature, high corrosion, high strength demand scenes, better performance but higher cost.
