Ferroalloy ore furnace -Ferroalloy ore furnace
Silicon manganese furnace use:
The main purpose of the furnace is to add qualified manganese ore, silica, manganese rich slag, carbonaceous reducing agent, dolomite or lime and other raw materials to the furnace according to a certain proportion of ingredients. The high voltage power supply is input by the mineral furnace transformer, short net system and electrode holder, and the electrode is inserted into the charge for submerged arc smelting. After a certain period of smelting, the iron slag is removed to the high and low molten iron ladle, the slag flows out through the low molten iron ladle, is quenched by water to the slag pond to cool, and then hauled out of the car with a grab bucket; Molten iron is broken after casting, and packaged and stored in quantity after finishing. Process features: self-baking electrode is selected, and the furnace lining is made of carbon brick and high aluminum refractory brick. An electric furnace with continuous feeding, intermittent iron discharge and continuous operation.
Silicon manganese furnace equipment composition:
The mechanical part of the silicon manganese furnace is mainly composed of the furnace shell, semi-enclosed (or fully enclosed) low smoke hood system, electrode holder system (you can choose the combined type holder or pressure ring type holder), short mesh system, smoke exhaust system, distributing system, blanking system, hydraulic system, pneumatic system, and electric furnace cooling water system. Auxiliary equipment: batching system, feeding system, iron system, slag system, casting equipment, product finishing system, etc. The exhaust gas purification and recovery device uses a large cloth bag cyclone dust removal device. The electrical part of the silicon manganese furnace is composed of high voltage system (switch station), low voltage system, large screen monitoring system and automatic control system.
Main uses of 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.
