Abstract

The invention was involved in compound refiner in metallurgy. It consist of 30%-50% silicon calcium alloy+ silicon calcium cinder, 10%-30% silicon barium alloy + silicon barium cinder, 15% carbide, 5%lime stone or aluminous, and 20% magnesium+ magnesium cinder. Compared with the exist products, this invention was with short periodic time, low cost, fine effect of deoxidation, desulfuring, removing inclusion in molten steel and improving the effect of denaturation of molten steel. The inside quality of steel was improved by purifying molten steel.

Description

[0001] The present invention belongs to a divisional application, the original title of the invention is "a metallurgical composite refining agent", the application number is 02113206.2, and the application date is January 7, 2002. technical field

[0002] The invention relates to a metallurgical refining agent, in particular to a compound refining agent for metallurgy. Background technique

[0003] Steel refining is an important link in modern steelmaking production. In the tapping process of oxidizing molten steel, specific substances can be added to achieve functions such as deoxidation, desulfurization, and removal of inclusions in steel, and at the same time, it is also conducive to improving the alloy yield. Doing a good job in tapping and refining links is of great significance for reducing the load of refining outside the furnace, improving the internal quality of steel and reducing production costs. Traditional tapping additives are mostly simple synthetic slag des...
