Abstract

The existing technique of 'one step method' is adopted for producing the manganese-silicon alloy with high silicon that utilizes the dregs rich in manganese, silica, coke, charcoal and lime to manufacture the alloy in ore hot furnace. The one step method possesses the drawbacks of high requirement for the raw materials, high production cost and difficult operation. In the invention, two electric furnaces are used for matching the production process. One electric furnace produces general liquid manganese-silicon and the other produces liquid ferrosilicon. Then, the manganese-silicon and ferrosilicon are mixed together outside furnaces in hot condition. With phosphor removal agent and desulphurized being added in the said admixture, refining and pouring produces the commodity of the alloy.

Description

Production technology of high silicon manganese-silicon alloy
Technical field
The present invention relates to a kind of smelting process for production of high silicomanganese silicon.
Background technology
High silicon manganese-silicon alloy is the reductive agent of alloying constituent, complex deoxidization sweetening agent and smelting low carbon ferromanganese in steel-making and the casting.Existing high silicon manganese-silicon alloy production technique is with rich manganese slag, silica, coke, charcoal, lime, single stage method production in the hot stove in ore deposit, this production technique is high to raw-material requirement, the production cost height, and operation is difficulty, the production difficulty is big, therefore, develop a kind of new high silicon manganese-silicon alloy production technique, can control production cost preferably, operation has easily become current important topic again.
Summary of the invention
It is low to the purpose of this invention is to provide a kind of cost, easy-operating MANUFACTURE OF SILICO-FERROMANGANESE WITH HIGH-SILICON technology.
The objective of the invention is to realize in the following way: a kind of production technology of high silicon manganese-silicon alloy, adopt two electric furnaces to form a complete production network, an electric furnace is produced common liquid manganese-silicon, another electric furnace is produced liquid ferrosilicon, carrying out the outer heat of stove then converts, and add dephosphorization and desulfurization agent refining, cast, form the commodity high silicon manganese-silicon alloy at last;
The composition of liquid ferrosilicon requires: Si 〉=65%, P≤0.04%, S≤0.02%,
The composition of liquid manganese-silicon requires: Si 〉=18%, Mn 〉=66%, P≤0.1%, S≤0.01%;
Liquid manganese-silicon is blended in the liquid ferrosilicon, add the dephosphorization and desulfurization agent, ladle-to-ladle repeatedly or shaking ladle between two hot metal ladle then, liquid manganese-silicon and liquid ferrosilicon are fully reacted, carry out bottom pouring after calm 5-15 minute, tapping a blast furnace from two electric furnaces should be controlled in 80 minutes to the duration of pouring.
The present invention has satisfied the requirement of users at home and abroad to high silicon manganese-silicon alloy composition Si 〉=25%, Mn 〉=55%, C≤0.5%, P≤0.1%, S≤0.01%, and production cost is low, has the market competitiveness.Description of drawings
