Converter is a kind of commonly used steelmaking furnace. Generally can be tilted cylindrical oxygen blowing steelmaking vessel. Furnace body is cylindrical, set on a horizontal axis frame, can be rotated, used for steelmaking. As the working conditions of the various parts of the converter vary greatly, this results in different damage to the individual …

In the continuous casting process, the tundish is not only considered as a transitional vessel for buffering, storing molten steel, diverting flow and realising continuous casting in multiple furnaces, but also has important metallurgical functions. At present, most of the baffle walls, baffle dams and turbulence controllers and other combination of flow control components to …

1.The life of the skateboard is relatively low. At present, the material of the domestic converter skateboard is mostly aluminum-zirconium carbon. As the material of the ladle skateboard, it has high strength, good thermal shock resistance, and excellent erosion resistance and corrosion resistance; But for the converter skateboard to block slag technically, the service life …

Some of the problems that occur during the use of tundish refractory materials are the quality of the material itself, and some are related to the on-site construction and need to be carefully observed and analyzed. Dry material has no strength Before the tundish is put into use, the dry material of the working layer needs to have a …

The sliding nozzle is composed of upper and lower sliding plates and 4 refractory bricks for the upper and lower nozzles. The pouring of each ladle of molten steel must pass through the upper and lower sliding plates and the upper and lower nozzles, so they are very strict. Firstly, they must have sufficient strength at high temperatures to …

The methods of slag blocking are as follows: Blocking slag once by slag blocking cap method; Secondary slag removal is blocked by slag ball method, floating plug method, pneumatic slag monoblock stopper method, pneumatic slag blowing method, etc. (1) Slag cap. A conical slag cap made of steel plate is blocked outside the tapping hole to block …
Argon blowing is usually to build one or several ladle purging plug at the bottom of the pouring ladle or brick ladle. After tapping, blow argon gas through the breathable bricks to cause agitation of the molten steel in the ladle. Argon blowing can promote the floating of emulsified slag droplets and inclusions in steel, and can …
