Submerged arc furnace¡ait¡¡¥s also known as electric arc furnace or resistance electric furnace. It is mainly used to reducing smelting ore, carbonaceous reducing agent and solvent etc. Mainly adapts to production of ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon manganese alloy and other ferrous alloys, it is an important smelting furnace in metallurgical industry for production of industrial raw materials and calcium carbide and so on chemical raw materials. The working character is to use carbon or magnesia refractory materials as furnace lining, use self roasting electrode. Electrode inserts into the materials inside the furnace for submerged arc operation, using arc energy and current through the materials, and due to the resistance of the materials and produce energy to melt metal. It¡¡¥s a kind of industrial furnace which is worked continuously, charged material in succession, and tapped out metal or slag in intermittent.
Capacity:3000kva-33000kva, smelting different ferroalloy by ores.
Electric arc furnace uses electricity as fuel source and utilizes the arc high temperature produced by electrode and furnace charge to heat and melt the furnace charge. It is widely using in production of normal steel, high quality carbon steel, various alloy steel, stainless, various ferroalloys. It is the key equipment in steel making factories, foundry factories, ferrous alloys making factories and etc.
Vd/vod ladle vacuum refining process strengthens blowing argon reasonably on the bottom of furnace; it can stir molten steel adequately and get ideal dynamics effect. If combining vd and lf, the furnace can get ideal molten steel refining temperature with easy structure and low cost. Both of the above process can dehydrogenize, denitrify, desulfurize, deoxidize under vacuum conditions and get the function of vacuum oxygen decarburization (vod) to achieve the purpose of refining super pure steel.
Argon oxygen furnace is a kind of ladle refining furnace, which is characterized by side-blowing oxygen through the bottom tuyere with an immersion way. When the tuyere center is blown in with oxygen, argon and mixed gas of nitrogen, the proportion of argon and oxygen should be adjusted, then, it can achieve the purpose of decarburizing and retaining of chrome. Argon and nitrogen are used as cooling gas for tuyere ring to extend the life of tuyere. It can get the best operation by controlling the flow of the tuyere ring. And the flow of the tuyere center and tuyere ring can be controlled in master-control room.
Ladle refining furnace is used to refine the molten steel from primary melting furnace (electric arc furnace, induction furnace, converter and etc.), meanwhile have the function of adjusting molten steel temperature, and be a buffer of the whole process. It is described to be soul of the best production line (primary melting furnace + lf+ ccm). It is widely used in refining all kinds of steel grade, such as ball bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and etc.
The most powerful commercial condensing boiler in the world, the E-Compact Twist is available in a wide range of outputs of 25kW up to 150kW, and is ideal for business owners who are looking to run a more energy-efficient business. The only condensing pellet boiler in the world with a single heat exchanger, the E-Compact Twist condensing boiler can achieve efficiencies of up to 103%.
