What is the effect of floor steel on the quality of construction machinery spare parts

"Floor steel refers to the waste steel as raw material, using power frequency, medium frequency induction furnace smelting inferior, low quality steel products".And clear the scope of elimination: "elimination of the production of floor steel, steel ingot or continuous casting billet of industrial frequency and medium frequency induction furnace and elimination of industrial frequency and medium frequency induction furnace production of floor steel, steel ingot, continuous casting billet, and the production of iron and steel products as raw materials."

Power frequency and medium frequency induction furnace using scrap steel, scrap iron as raw materials, production process does not have function of smelting, only the function of steel, not steel function, can't take effective slagging, remove phosphorus, sulfur and other harmful impurity element, remove the harmful gas in steel, normal micro alloying, power frequency and intermediate frequency induction furnace steel production quality completely depends on the quality of scrap,The qualified molten steel with balanced and stable composition can not be produced, and the acid refractory used in furnace lining will produce spinel inclusions that cannot be removed, and too many impurities will accumulate in the steel matrix, which will directly affect the final performance of steel.The production process of floor steel consumes up to 600 KWH of electricity per ton, and a large amount of dust is discharged in the smelting process. If the monitoring is not in place, the environment will be seriously polluted.

Normal steel smelting is in molten state, through the study of the temperature of molten steel in the furnace of decarburization, removing inclusions, removing harmful elements, deoxidation alloying, make steel alloy elements in the accurate in meeting the requirements of the steel grade standard range, can guarantee the steel mechanical property, these goals can only be achieved by oxygen top-blown converter or electric arc furnace production

Quality can not be guaranteed, OEM production, illegal counterfeiting, destroy market order
Because the product quality can not obtain the market recognition, can only fake the regular iron and steel enterprise brand sales.Seriously disrupt the order of regional steel production and sales;Some enterprises even rely on low-price export, which interferes with the international market order and causes trade disputes such as double countervailing, which has seriously affected Company's international image.
