Electric Arc Furnace - Electrotherm - Engineering Applied Sciences

Electrotherm affords an entire range of melting models -high-impedance Electric Arc Furnaces with the capability for producing heat sizes from three Ton to 200 t in technical collaboration with Vitkovice Heavy Equipment, Czech Republic. Raw materials may be as much as 100% scrap or numerous mixes of hot steel, pig iron, DRI (scorching and/or chilly) and HBI, utilizing electrical and chemical power, in keeping with unit costs and site - please click the next page, energy grid characteristics. The Electric Arc Furnace operation will be made absolutely computerized by applying a collection of technological packages to optimize the method, to be selected on a case-by-case foundation depending on the performance figures to be achieved.

One other downside encountered in the present conveyor-hood type preheating systems is the uneven preheating of the scrap. The thickness of the mattress of scrap can differ alongside the conveyor. Moreover, the spacing of the burners, by necessity, must be unfold out along the hood. Consequently, the flames from the burners will impinge extra directly upon the scrap immediately beneath the burners than on the scrap between adjoining burners. Additional yet, the flames from the burners solely strike the top surfaces of the scrap. It's an object of the current invention to offer a scrap preheating system of the conveyor-hood sort which includes structure within the hood itself for complete combustion of unburned hydrocarbons.

Steel scraps are first separated, graded, and sorted into totally different courses of steel in scrap yards. The scrap yard operator will put together buckets of scrap based on the wants of the smelter. The scrap is layered in the bucket in accordance with dimension and density to advertise the speedy formation of molten steel in the furnace, and minimize scrap cave-ins, which might break electrodes.
