Description

technical field

[0001] The invention relates to a silicon-calcium carbonaceous deoxidizer. technical background

[0002] Deoxidation of molten steel is an important part of steelmaking production. Conventional AL-containing deoxidizers include metallic aluminum, silicon-aluminum-iron, silicon-aluminum-barium, etc., and their prices are generally high. Deoxidation with AL deoxidizers generally results in deoxidation products containing AL2O3 The inclusions are harmful to the quality of the steel, and it is also easy to cause nodulation at the outlet. Contents of the invention

[0003] The technical problem solved by the invention provides a silicon-calcium carbon deoxidizer, which has good deoxidation effect, reduces steelmaking cost and improves steelmaking efficiency.

[0004] In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: a silicon-calcium carbonaceous deoxidizer, the chemical composition weight per...
