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 size of 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
The present invention relates to a kind of drainage agent and preparation method thereof, particularly a kind of ladle draining ageng made of chromium and preparation method thereof belongs to fire resisting material field.
Background technology
Draining ageng made of chromium is mainly used in ladle draining, and present stage, middle-size and small-size ladle draining mainly used siliceous drainage agent, and draining ageng made of chromium is mainly used in the molten steel drainage of big-and-middle-sized ladle, has obtained good effect.But also there are following problems:
1, casting rate is not high, reaches about 90%.
2, do not open water usually need drainage, just burn facing to slide gate nozzle with the oxygen rifle, both having lost time influence STEELMAKING PRODUCTION efficient, also the very big potential safety hazard of existence.
It is 02109237.0 that State Intellectual Property Office discloses a patent No. on December 4th, 2002, name is called the patent of invention of " draining ageng made of chromium ", this patent provides a kind of refractory materials, it is characterized in that: be to be made by following raw materials according per-cent by weight: silica (granularity 0.5～2.0mm) 15～30%, silica (granularity＞2.0mm) 5～10%, chrome ore (granularity＞2.0mm) 50～78%, graphite 0.5～1%.Draining ageng made of chromium of the present invention can automatic casting in the metallurgy industry smelting process during steel ladle casting, thus avoided because of burn that the oxygen drainage may occur emit steel, the accidents such as steel and operator's burn of staggering.
" draining ageng made of chromium " casting rate of above patent disclosure is still not high, and complex production process, the cost height.
