Brief introduction of insulation agent for stainless steel and alloy steel

The heat preservation performance of molten steel in ladle is related to the tapping temperature and the quality of the later casting, so it is deeply concerned by the metallurgical development industry. At present, in order to ensure the smooth pouring of molten steel, it is necessary to add a certain amount of ladle heat preservation agent to the surface of molten steel after tapping for heat preservation. For this reason, our factory has been entrusted by many steel mills to develop this product. This product is developed by our scientific and technological personnel under the technical guidance of Harbin University of technology. It has been used well by many steel mills.

1、 Features of stainless steel insulation agent:

1、 Features of stainless steel insulation agent:

1. After tapping, ladle heat preservation agent is added to reduce the heat loss of molten steel, prevent the secondary oxidation of molten steel, and ensure the smooth pouring of steel (continuous casting, mold casting), especially the refining outside the furnace can increase the temperature of molten steel.

3. Application scope of heat preservation agent: heat preservation agent can be used in hot processing industries such as blast furnace, converter, refining furnace steel making, stainless steel production, etc. it can quickly gather slag into slag shell which is easy to separate from molten metal, and then can be quickly removed to ensure the cleanness of molten metal.

4. Due to the addition of aluminum powder, the stainless steel heat preservation agent can increase the temperature of molten steel (10-20) ℃, especially in the refining outside the furnace. Because of the long distance, the temperature of molten steel in the furnace is kept the same, the heat loss is reduced, and the temperature of molten steel is guaranteed.
