Refining to remove oxidesAt the end of the secondary refining, in order to obtain high purity molten steel, so-called "bubble floating purification" is required. Here, "bubble floating and purification" means the boiling of molten steel caused by small bubbles near the bottom of the ladle top slag r

Denaturation of secondary refining inclusionsThe inclusions are denatured by adding calcium-containing materials, such as CaSi. CaSi can be blown into the furnace with a spray gun, or added to the furnace in the form of a core wire. The denaturation of inclusions can be studied with the CaO-Al2O3-Ca

Secondary refining refers to the refining outside the traditional steelmaking furnace (such as open hearth, refined furnace, electric furnace). The main tasks of refining are deoxidation, desulfurization, dephosphorization, decarburization, removal of inclusions, alloying and fine-tuning of composit

In recent years, with the continuous increase of system capacity and single transformer capacity, under the premise of certain transformer impedance, the threat of short-circuit electromagnetic force to the transformer has become more serious. Therefore, in order to ensure the safe and reliable oper

The induction melting vacuum degassing furnace firstly melts the metal (or vacuum) in an atmospheric environment. The molten metal is degassed under vacuum in the refining stage, and the liquid metal is cast under the atmosphere or under the protection of inert gas. Consac company has improved and o
