Self-flowing refractory castables are a type of refractory castable material with self-leveling properties, which are widely used in the lining construction of high-temperature industrial equipment and furnaces. Compared with traditional วัสดุทนไฟที่หล่อได้, they have the advantages of simple construction, การปรับตัวที่แข็งแกร่ง, and high cost-effectiveness. Self-flowing castables can flow into the predetermined area by their own weight without the need for external vibration to form a tight lining layer. They are widely used in industries such as metallurgy, เซรามิกส์, petrochemicals, กระจก, and electricity.

Characteristics of self-flowing refractory castables

The construction method of self-flowing castables is different from that of traditional refractory materials. It can be poured directly into the equipment through pipes, so as to achieve the purpose of quickly and evenly coating the surface of the equipment. This construction method can not only save time and labor costs but also reduce human errors during construction and improve coating quality.

Self-flowing castables also have good mechanical strength and thermal stability, and can maintain their stability and corrosion resistance at high temperatures. นอกจากนี้, the surface of self-flowing castables is smooth and flat, which can effectively reduce the friction loss of the fluid inside the equipment, improve production efficiency and equipment service life.

Self-flowing castables have many advantages that other types of castables cannot match. They can be used for continuous casting tundish linings, electric furnace top triangles, tapping ports, steel ladles, เตาเผาความร้อน, blast furnace tapping channels, CAS-0B furnaces, cast iron induction furnaces, boiler protection tubes, เป็นต้น.
