1.Overview of the Silicon manganese Alloy Submerged Arc Furnace
Silicon manganese Submerged Arc Furnace is mainly used to proceed the submerged arc smelting by mixing up qualified manganese ore,silica, rich-manganous slags ,carbonaceous reducing agent,dolomite ,CaO and other material with specific proportion, filling into the Silicon manganese Submerged Arc Furnace, inputting high voltage through transformer,high current supply system and electrode holder and submerging the electrode into material. After a period of smelting, tapping the molten iron into high and low ladle, outflowing from low iron ladle, water quenching and cooling into slag pool, grabbing and carting out, moulding by casting, smashing, finishing, and then, quantitative packaging into storage.
Technology Feature: applying self-baking electrode,carbonaceous brick and high alumina refractory brick as furnace lining,continuous charging,intermittent tapping,continuous processing.
2.Composition of the Silicon manganese Alloy Submerged Arc Furnace
The mechanical part of the Silicon manganese Alloy Submerged Arc Furnace mainly consists of furnace shell, semi-sealed or sealed low hood, electrode holder(combined holder or pressure ring holder),high current supply system, smoke extraction system, charging system, feed system, hydraulic system, pneumatic system, water cooling system, etc. Auxiliary equipment consists of batching station, charging system, tapping system, slag-out system, casting equipment, finishing system, etc. Exhaust gas purification recovery device adopts big bag cyclone de-dusting device. Electrical part consists of high voltage system (switching station), low voltage system, large screen monitor system and automatic control system.
3. Usage of Silicon Manganese Products
Silicon Manganese Alloy:Silicon manganese alloy is an alloy composed of silicon, manganese, iron and a small amount of carbon and other elements. It is a kind of iron alloy with wide use and large yield. Its consumption accounts for the second place in electric furnace ferroalloy products. Manganese and silicon in manganese silicon alloy and oxygen affinity is strong, in the use of manganese silicon alloy in steelmaking, the resulting deoxidation products MnSiO3 and MnSiO4 melting point of 12700C and 13270C respectively, with low melting point, large particles, easy to float, good deoxidation effect and other advantages. Under the same conditions, using manganese or silicon deoxidation alone, the burn loss rate is 46% and 37%, respectively, while using manganese silicon alloy deoxidation, the burn loss rate of both is 29%. Therefore, it has been widely used in steelmaking, and its output growth rate is higher than the average growth rate of ferroalloy, higher than the growth rate of steel, becoming an indispensable composite deoxidizer and alloy addition agent in the steel industry. Manganese silicon alloy with carbon content below 1.9% is still used for the production of medium and low carbon ferromanganese and electrosilicothermal metal manganese semi-finished products.
