Product description of stainless steel and alloy steel covering agent

The heat preservation performance of the molten steel in ladle is related to the tapping temperature and the quality of the billet in the later stage, 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 covering agent to the surface of molten steel for heat preservation after tapping. 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、 Characteristics of covering agent:

1、 Characteristics of covering agent:

1. After tapping, ladle covering 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.

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