Intermediate frequency furnace smelting steel technology, an intermediate frequency furnace smelting iron tonnage costs a: this depends on many factors, such as the choice of electric furnace, the selection of the transformer, the selection of raw materials, all you have to do the kinds of castings, electricity, etc. , you need to provide data to calculate the cost. Such as high-grade 15 tons of intermediate frequency furnace and low power consumption, the selection of refractory material, you are pig iron smelting use cash or scrap steel smelting, the cost is different also, and so on. I don't understand of the casting, I want to ask: 50% with 50% scrap and waste iron answer: use 50% 50% scrap steel and cast iron scrap in 500 kg of intermediate frequency furnace smelting, generates? A: white iron, Equal in yuan in burn in) Intermediate frequency furnace smelting is alloy composition will not change. Give me email address, send you the intermediate frequency furnace carbon steel and alloy steel melting technology electronic draft. Medium frequency furnace melting grey iron medium frequency furnace melting cast steel answer: simply talk with induction furnace smelting grey cast iron of some main metallurgical characteristics, for your reference. Induction furnace melting system of gas content in liquid iron with cupola melting, compared with coreless induction furnace melting cast iron, the metal burden and furnace gas contact time is short, molten metal in contact with the furnace gas interface is small, thus, induction furnace smelting. 1 acid lining material: carbon steel smelting. Quartz sand ( 20/40) 40%, quartz sand, 50/100) 5 ~ 2% ( Plus) 2%, water ( Plus) 。 Quartz sand should be magnetic separation, remove the ferromagnetic material. Alkaline lining: for alloy steel smelting. Magnesia ( A 4 x 4 mm sieve) 96%, refractory clay, No. 100. What elements of lossy medium frequency electric furnace smelting? If have the answer: the oxidation burning loss is inevitable, but it can be according to the experience of the losses to a minimum, general carburant in advance to be conducive to better dissolved in molten iron, alloy elements join to help reduce the loss when see the molten iron, as to which elements are burning, according to the experience Mn> Cr> C> Si> S> Cu burning loss rate at 3% 10% ranges, each foundry process caused by the different burning loss rate. What is the advantage of intermediate frequency electric furnace smelting iron on a: medium frequency induction furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency ( More than 300 hz - 1000 hz) Power supply device, the three-phase alternating current (ac) power frequency, after rectification into direct current, then laid adjustable intermediate frequency electric current, direct current supply by capacitance and induction coil in through the intermediate frequency alternating current, generate high density magnetic field lines in the induction coil, induction and cut. How intermediate frequency electric furnace iron medium frequency furnace melting cast steel answer: intermediate frequency electric furnace electrical efficiency and high thermal efficiency, short smelting time, save electricity, covers an area of less, low investment, easy to implement process automation and production flexibility. Intermediate frequency electric furnace for melting cast iron, especially suitable for smelting alloy cast iron, nodular cast iron and vermicular cast iron. It also strong adaptability to charge, charge of varieties and available in a wide range of fragmentation. The difference between cast iron and cast steel medium frequency furnace maintenance a: raw iron hard and brittle, lack of toughness, carbon content 211% 667% more iron carbon alloy and nonferrous impurities. Cast iron is more than 21% of the iron carbon carbon alloy, it is to cast iron ( Part of pig iron for steel making) To melt in the furnace, and adding ferroalloys, scrap steel, foundry return the components to adjust. With cast iron cast iron is the difference between secondary processing, processing into a mostly. Intermediate frequency furnace smelting metal lead is feasible, please answer: medium frequency furnace smelting is belong to the induction heating, as long as it is metal, the intermediate frequency furnace can produce inductive electromotive force, and hot melt. The melting point of lead is not high, the effect of intermediate frequency furnace smelting is pretty good. Hangzhou institute of revestment precision casting. When the medium frequency furnace melting scrap on the carburant? A: carburant can add when add burden, but want to consider the loss of 5 ~ 8%. Aluminum is the function of DNA should be added at the time of the steel, add quantity for 3 ~ 05%. Medium frequency furnace melting cast steel technical data 15 tons of intermediate frequency furnace smelting furnace needs much time medium frequency furnace melting cast steel a: about an hour, basically see what product. Cast steel and electric furnace smelting with what equipment? Intermediate frequency furnace smelting steel casting a: tell me: carbon steel or stainless steel castings? The annual output? What kind of sand. Intermediate frequency furnace smelting stainless steel workshop layout a: stainless steel points without magnetic and magnetic, a magnetic can use the intermediate frequency furnace smelting, such as martensite and ferrite and duplex stainless steel are available intermediate frequency smelting; Austenitic stainless steel without magnetic is can't. Cast iron, cast steel and nonferrous alloy melting furnace can be used separately? Intermediate frequency furnace smelting steel casting a: cast iron, cast steel and nonferrous alloy melting furnace can be used separately? Answer: cast iron, : converter, cupola, power frequency furnace; Cast steel, converter, electric arc furnace, intermediate frequency furnace; Nonferrous alloy melting, radiation furnace.
