Description
Technical field
This utility model relates to continuous induction melting furnace, particularly relates to a kind of novel high-efficiency and energy-saving continuous induction melting furnace.
Background technology
Current quartz tubulation (rod) industry uses highly energy-consuming continuous induction melting furnace, so power supply department claims quartz trombone slide enterprise for large electricity consumer, electric power district government insufficiently forbids this project construction, even if some areas are constructed and put into operation, being typically in annual July and peak times of power consumption two months Augusts will ration the power supply in blowing out, not so resident, school, hospital, market, government bodies' electricity consumption will be greatly affected. The measure that blowing out is rationed the power supply so that the performance of enterprises is subject to the loss that cannot estimate, because continuous induction melting furnace electricity consumption can not stop, unless arranged by oneself shutdown maintenance to the cycle, it is simply that the loss of last resort shutdown maintenance is all very big. Generally, stop a stove to take and could stop completely for about 6 days, concrete operations are first to stop feeding in raw material, elevated currents oven (just roasting unclean because of the quartz material in not elevated currents tungsten crucible), quartz material in tungsten crucible all being baked, all bake without quartz material in tungsten crucible, tungsten crucible is easy for explosion, the tungsten crucible of explosion just becomes waste product, causes huge economic loss. When blowing out simultaneously, protective gas can't stop; to use gas and electricity always, until quartz material is dried clean in tungsten crucible, then slowly with 2 to 3 days time, electric current dropped; continuous smelting in-furnace temperature could have a power failure after lowering, and just can stop protective gas after about 12 times. Also crying igniting during blow-on, will first send protective gas then power transmission, just can go out qualified products after general 3 days, producing qualified products could be profitable.
Under normal circumstances, stopping stove and drive stove and take around the direct cost without benefit of about 30,000 yuan, indirect loss expense also cannot budget. Produce quartz ampoule and quartz pushrod, quartz plate must use continuous induction melting furnace, cannot produce again without continuous induction melting furnace, do not have other equipment to can substitute for tradition continuous induction melting furnace at present both at home and abroad, only try every possible means on continuous induction melting furnace is energy-conservation, it is ensured that loss is preferably minimized when blowing out or production by enterprise.
