What are the raw material requirements of silicon calcium alloy?
Silicon calcium alloy is a new type of composite material, with customized content and targeted use, silicon calcium alloy is more affordable than traditional metallurgical materials, which is often used by many manufacturers in steelmaking and casting products. For the silicon calcium alloy manufacturers familiar with the silicon calcium alloy which raw materials and proficient in the requirements of raw materials is the premise of the production of high-quality silicon calcium alloy!
Necessary raw materials for the production of silica-calcium alloys：
Want to produce silicon calcium alloy first of all must prepare for the production of silicon calcium alloy raw materials, the production of silicon calcium alloy more methods to prepare the raw materials are slightly different, in order to use the frequently used one-step production of silicon calcium alloy, want to smelting silicon calcium alloy need to prepare the ferroalloy raw materials are silica, lime, coke, wood blocks, charcoal, bituminous coal!
What are the requirements of silicon calcium alloy for raw materials?
What are the requirements of silicon calcium alloy for raw materials
Silica requires SiO2 content greater than 98%, Al2O3+Fe2O3 content less than 1%, the less other impurities the better, the surface can not be stuck with soil or other impurities, water absorption rate less than 5%, silica furnace particle size of 30~60mm, of which more than 60mm less than 30mm part is less than 5%.
The CaO content in the lime is greater than 85%, the Al2O3 content is less than 0.5%, the Fe2O3 content is less than 0.3%, and the raw and overburned lime is not mixed, and the furnace particle size is 10~15mm
The fixed carbon of coke should be greater than 80%, the ash content is less than 15%, the furnace particle size is 3~5mm, and the coke powder should be less than 10%.
Charcoal fixed carbon is greater than 75%, ash is less than 2%, volatile content is less than 20%, moisture is less than 10%, must not be mixed with raw burning wood head, powder and other impurities, block degree 20~80mm.
The wood block is made of ordinary pine miscellaneous wood, without bark, with a thickness greater than 20mm and a length less than 200mm, of which the thickness less than 20mm should be less than 5%.
Bituminous coal requires ash content less than 8%, moisture less than 10%, not mixed with other impurities, to have good sintering performance into the furnace particle size of 0~13mm.
