Abstract

The invention relates to a chrome fluxing agent for steel ladles and a preparation method thereof and belongs to the field of refractory materials. The chrome fluxing agent for the steel ladles is prepared from the following raw materials in parts by weight: 68-72 parts of chrome ore, 11-22 parts of silicate rock with the particle size of 1-2 mm, 6-10 parts of silicate rock with the particle sizeof 0.5-1 mm, 4-7 parts of potassium feldspar, 0.004-0.008 part of carbon black, 0.002-0.004 part of crystalline flake graphite, 0.0005-0.001 part of F4 binding agent and 0.0001-0.0003 part of water. The chrome fluxing agent for steel ladles is prepared through the steps of material preparation, metering, mixing, material discharge, packaging, and the like. Through adding the new F4 binding agent and a lubricating agent (crystalline flake graphite) into the fluxing agent provided by the invention, a new chrome fluxing agent for steel ladles, which is higher in open-casting rate, lower in production cost and friendlier to application environment, is produced.

Description

Technical field [0001] The present invention involves a drainage agent and its preparation method, especially a steel -wrap chromium drooling agent and its preparation method, which belongs to the field of refractory materials. Background technique [0002] Chrome drainters are mainly used for steel bag drainage. At this stage, small and medium -sized steel bag drainage mainly uses silicon drainters. The steel drainage of large and medium -sized steel bags mainly use chromium drainters, which has achieved good results.But there are also some problems: [0003] 1. The opening rate is not high, up to about 90%. [0004] 2. It often needs drainage that cannot be poured, that is, using oxygen guns to burn in the sliding water mouth, which not only wastes time affecting the efficiency of steelmaking production, but also has great hidden safety hazards. [0005] On December 4, 2002, the State Intellectual Property Office released a patent number 02109237.0, named "Chrome Dutch", which ...
