Intermediate frequency furnace steelmaking desulfurization? Steel demand is not high, the best low cost when the intermediate frequency furnace scrap and how much cost a: medium frequency furnace melting scrap, no smelting functions. Lower the cost of desulfurization can consider slag washing process, is in the process of tapping, adding lime or desulfurizer desulfurization in the ladle. Scrap steel need what equipment, answer: scrap steel need equipment - Intermediate frequency electric furnace steelmaking - Small electric furnace steelmaking, ( In our country in liaoyang, plump, LeLing, taizhou, high efficiency) Medium frequency melting furnace - The main points of the intermediate frequency furnace steelmaking is introduced as follows: a, the task of smelting steel part of the main raw material is steel scrap and pig iron. Outsourcing in scrap steel rust, with mud and other dirt, intermediate frequency smelting steel. In 2017 after the closure of intermediate frequency furnace scrap down price? A: intermediate frequency furnace generally just melting scrap, don't adjust the carbon content! If you want to adjust the carbon content, oxygen blowing off carbon oxide, it don't have this ability, also have no test ability. What is the cost of steel? Electricity costs in it? Intermediate frequency furnace scrap and how much cost a: cost analysis the production cost of ironmaking process constitute main raw materials, Pellets, iron ore, etc. ) , auxiliary materials ( Limestone, silica, refractory materials, etc. ) , fuel and power, Coke, coal, gas, oxygen, water, electricity, etc. ) , direct wages and benefits, manufacturing costs, the cost is deducted ( Gas recovery, recycling water slag, coke undersize material recycling, etc. Eia of intermediate frequency furnace steelmaking why must have a spare stove a: intermediate frequency furnace steelmaking power consumption related to many factors, such as the stand or fall of the filial piety of scrap steel and medium frequency furnace furnace working technology and frequently lazy and so on. Generally speaking, the power consumption between 550 ~ 750 degrees, large-tonnage stove and lower power consumption, small tonnage. Steelmaking production scrap use ratio is normal how much scrap and intermediate frequency furnace cost how much a: 21 tons of molten iron, 65 tons of scrap steel. We charge weight. The book theory of around 21%. Specific look at the situation. Physical chemistry you there hot heat, continuous casting equipment, scrap the same. Scrap ratio = scrap/scrap + pig + molten iron. In the past decade, 2005 - 2014) , the global steel scrap in 35 - to maintain The level of 40%, the average is about 37%. Scrap than most. Scrap market price a: by the steel billet, and the problem of phase screw prices collapsed the scrap steel market trend is spreading, and most of the decline in 300 yuan - within a week 500 yuan/ton. Tangshan heavy A2250 yuan - In early 2400 yuan/ton no tax, down 310 yuan - 370 yuan/ton; Liaocheng fine burden - 2200 yuan In early 2300 yuan/ton no tax, down 420 yuan - 440 yuan/ton. As of November 23, 2018, Mr Zhang. Converter: why do you want to add the scrap steel? What answer: different scrap steel in converter mainly for recycling scrap steel, and reduce the dosage of molten iron, reducing the cost. The influence of scrap steel in converter is mainly cause bigger impact on the furnace lining, reduce the service life of converter, is not too large, and the scrap had dry, no airtight container, otherwise it will splash. Those can add as to what you say, sometimes with too much by the molten iron of blast furnace production. Intermediate frequency furnace scrap and how many technical data when the intermediate frequency furnace steelmaking cost how to cut down the carbon content of steel scrap for example from zero intermediate frequency furnace scrap and how much cost a: intermediate frequency furnace generally just melting scrap, don't adjust the carbon content! If you want to adjust the carbon content, oxygen blowing off carbon oxide, it don't have this ability, also have no test ability. Intermediate frequency furnace smelting grey cast iron scrap and intermediate frequency furnace to scrap what requirement cost how many answer: we are foundry, with medium frequency furnace hot metal. To scrap, we require composition is stable, single, generally do not use the alloy steel ( High manganese steel, chrome steel, etc. ) Waste, or composition control difficult. Scrap steel surface coating is not permitted in ( Oil, paint, etc. ) , not a closed tube, or refining process prone to danger. Water-based graphite should be on your scrap. Cultivation steel mills do not accept scrap steel? ( How much is 1 ton) ? Intermediate frequency furnace scrap and how much cost a: must collect scrap steel, but the price did not know. 90 tons of electric arc furnace with 90 tons of scrap steel to steel? Intermediate frequency furnace scrap and how much cost a: that's all scrap steel smelting. From the design and principle of electric arc furnace is no problem. But all scrap steel smelting use is only a special case. Now is the development trend of electric arc furnace, electric arc furnace of converter. Is the electric arc furnace are also like that using blast furnace hot metal, also for oxygen blowing of converter operation ( Furnace oven door wall oxygen lance, oxygen lance) 。 Because into molten iron has a lot of electric arc furnace. How to reduce the cost of electric arc furnace steelmaking scrap and cost how much a: intermediate frequency furnace for smelting and casting cost to reduce the cost, reducing scrap in the main or technology exports accounted for more than 80% of the cost of 1 is the metal material, the cost of purchase is also very important in order to ensure the performance of molten steel in some 2 add agent can not be reduced, but may consider alternatives ( Low price) 3 electric power consumption is huge, to avoid the peak on 4, the performance of the electric furnace to reduce.
