Above-mentioned ac arc furnace water cooled cover, there is respectively the location-plate of level the both sides of described dust-removing flue, on location-plate, there is vertical locating hole, on bell framework, be welded with supporting seat, on supporting seat, there is fixed jack, fixed jack is corresponding with the locating hole of location-plate respectively, and locating hole is connected by the drift inserting with fixed jack.
Above-mentioned ac arc furnace water cooled cover, is connected with earthing or grounding means between described port decorative cover and bell framework.
The beneficial effects of the utility model are:
The utility model is increased by bell integral body, has increased the space of bell and steel scrap, has reduced the lighter meeting of electric arc and water cooled cover fanning strip when smelting, and has extended the service life of water cooled cover; Adopt 4 bell fanning strips and 18 to enter backwater road simultaneously, make the water route distribution of regional more reasonable, more balanced, eliminated the dead water region on bell framework, improve the whole cooling effect of water cooled cover, also reached the object that extends the service life of water cooled cover; The utility model has also increased lifting square chest, not be used in on-the-spot contraposition, is emitting high temperature to weld, thereby shortened the set-up time, also increased supporting seat simultaneously, with drift, directly dust-removing flue has been fixed on bell framework fast and accurately, also shorten the set-up time, alleviated labour intensity.
After the utility model comes into operation, extend to 6140 heats by original average 2739.125 heats service life, it is many that extend to twice service life, separate unit electric furnace can be saved more than 560,000 yuan of spare part expenses for 1 year, each bell of changing can shorten the set-up time of 4 hours, separate unit electric furnace 1 year can voluminous steel more than 2740 tons, has significant economic benefit.
