The steelmaking system includes a converter, electric furnace, furnace, ladle, ladle and tundish. Ladle and tundish is an important auxiliary equipment of the steel making furnace, and also the most important equipment for the use of refractory materials.
In the converter and electric furnace, the general use of refractory spray paint repair, the method is manual cast refractory materials, wet, dry or flame spraying and slag splashing furnace, etc…
In the electric furnace, the dry vibration material of the refractory material, the pre cast or cast in place or the furnace cover: triangle area and other parts are better use effect.
In the converter, the widespread adoption of slag splashing furnace maintenance technique and the service life of furnace can reach more than 10000 times; outside furnace refining furnace are more, the RH process and the method of DH degassing device insertion tube lining of the body, generally with high aluminum refractory material is poured into a whole, the service life is 20-80 times.
