Abstract
The invention provides a molten iron pretreating slag-off agent and a preparation method thereof. The invention is characterized in that the molten iron pretreating slag-off agent consists of the following raw materials which are mixed according to the weight percentage: pearl powder of ranging from 70 to 80 percent, quartz sand of ranging from 5 to 10 percent, glass of ranging from 5 to 10 percent and borax of ranging from 2 to 5 percent; the preparation method is realized by the steps of grinding the raw materials, stirring and mixing the raw materials and drying the raw materials. The invention is mainly used for the steel making process in the metallurgy industry and steel slag treatment after the molten iron pretreatment. The molten iron pretreating slag-off agent and the preparation method can rapidly gather and deslag the steel slag, have strong ability to absorb and gather the slag, great viscosity and little iron loss and can effectively and rapidly separate the iron from the slag, thereby increasing the output of the enterprise, lowering the production cost for the ironmaking enterprise and improving the economic benefits of the enterprise.
Description
Technical field:
The invention belongs in the metallurgy industry iron and steel smelting process, slag is handled after the hot metal pretreatment removes agent.
Background technology:
Hot metal pretreatment technology is one of necessary means of smelting Clean Steel, in hot metal pretreatment technology, the enterprise that has adopts the mode of magnesium powder winding-up to carry out the desulfurizing iron pre-treatment, molten iron and scum viscosity after this method is handled are bigger, some molten iron is along with slag is drained, and severe patient competes to contain 50% iron in the blast furnace slag of discharge, cause bigger waste, cause manufacturing enterprise to produce bigger production cost; The molten iron dioxide-containing silica that enters in the converter is bigger, and the steel quality of producing descends.
Summary of the invention:
The purpose of this invention is to provide a kind of fast poly-slag, and the molten iron slag gathering that can be effectively the iron in the slag and slag be distinguished removes agent and preparation method thereof.
Realize that technical scheme of the present invention is: molten iron pretreatment slag-gathering removing agent is mixed by following raw materials according and forms, by weight percentage pearl powder 70%～80%, quartz sand 5%～10%, glass 5%～10%, borax 2%～5%.
The preparation method that molten iron slag gathering removes agent realizes by following step:
1, above-mentioned raw materials is milled to 50～70 purpose granularities;
2, by above-mentioned prescription the ground raw material was stirred in mixer 20 minutes, make mixture;
3, said mixture is dried through dryer, being dried to water content is 0.2%～0.4%.
The present invention is slag-gathering removing fast, and its slag absorbing, poly-slag ability are stronger, and viscosity is bigger, and iron loss is less, fast and effeciently iron in the slag and slag is separated, and has improved the output of enterprise, and enterprise reduces production costs for ironmaking, improves the business economic benefit.
Embodiment:
Embodiment one: molten iron pretreatment slag-gathering removing agent is mixed by following raw materials according and forms, by weight percentage pearl powder 80%, quartz sand 9%, glass 9%, borax 2%.
The preparation method that molten iron slag gathering removes agent realizes by following step:
1, above-mentioned raw materials is milled to 50～70 purpose granularities;
2, by above-mentioned prescription the ground raw material was stirred in mixer 20 minutes, make mixture;
3, said mixture is dried through dryer, being dried to water content is 0.25%.
Embodiment two: the proportioning raw materials of present embodiment is pearl powder 77%, quartz sand 10%, glass 10%, borax 3% by weight percentage, and the preparation method is identical with embodiment one.
Embodiment three: the proportioning raw materials of present embodiment is pearl powder 75%, quartz sand 10%, glass 10%, borax 5% by weight percentage, and the preparation method is identical with embodiment one.
