Where are refractory materials mainly used

The steelmaking system includes converter, electric furnace, off-furnace refining furnace, ladle and tundish and other equipment. In electric furnace, dry vibration material, prefabricated or cast-in - situ furnace cover or use of furnace cover: triangle area, etc., all obtain better fire resistance; Fused magnesia manufacturers, in the converter and electric furnace, generally use fire-resistant spray paint to repair the damage, the method is by hand repair, wet, dry or flame spraying and slag splashing furnace protection methods. In the converter, the traditional slag splashing technology is generally used to protect the furnace, and the furnace life can reach nearly 10,000 times. There are many types of refining furnaces outside the furnace, and the RH method and DH method degassing device are inserted into the corresponding pipe liner body, generally cast into a large area of high aluminum refractory castable, and the service life is about 20 to 80 times. Ladle and tundish are the important auxiliary industrial equipment of steelmaking furnace, and also the thermal equipment that consumes the most refractory materials.

The iron system includes sintering, coking and blast furnaces and their auxiliary equipment. Belt sintering machine ignition furnace with refractory plastic and clay combined refractory castable on site, or with phosphate refractory castable prefabricated block lifting, its service life is 3~6 years. When the line ignition device is used, the top of the furnace is pressed down more, the working condition of the furnace is better, and the refractory castable or refractory fiber and its products can be used as the lining, and better results can be obtained.
