Silicon Manganese 6014

In the process of converter smelting low silicon low carbon steel, it is necessary to deoxidize and alloyed the liquid steel, because the content of silicon in the steel is quite low, so in the prior art, deoxidizing and alloying alloys avoid using materials containing silicon, before the use of silicon manganese alloy 6014 usually uses aluminum manganese titanium, aluminum manganese calcium, aluminum wire and carbon ferro manganese as deoxidizing and alloying materials.

In order to solve the problem of high smelting cost and difficult floating of inclusions by reasonable operation of oxygen removal of silicon, the method of using silicon manganese alloy 6014 alloy deoxidation alloying is proposed. The invention adopts the method of deoxidation alloying silicon manganese alloy 6014 to remove silicon contained in silicon ferromanganese alloy in liquid steel with high dissolved oxygen content, and the aerobic operation of the converter can effectively remove silicon in silicon ferromanganese alloy; At the same time, because the price of Si-Mn alloy 6014 is very low compared with Fe-Mn alloy, this kind of deoxidation alloying method can reduce the cost of smelting low-silicon low-carbon steel; In addition, because silicon ferro manganese alloy does not contain aluminum, so the addition of silicon manganese alloy 6014 to the liquid steel will not produce aluminum oxide, the inclusion in the molten steel is easy to float, will not affect the refining process.
