Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As illustrated, using residual heat type electric arc furnaces, including body of heater 1, fire door 2 and go out liquid track 4, the fire door 2 is located at stove
Side-walls are leaned in the bottom of body 1, go out liquid track 4 immediately below fire door 2, also including the fire door 3 on the side wall of body of heater 1, heat collector cavity 5 and send
Material device 6, the thermal-arrest mouth of the heat collector cavity 5 is arranged on out on liquid track 4, and heat conduction mouth is connected with the base plate 7 of pay-off 6, described
The discharging opening of pay-off 6 is connected with fire door 3.
Such scheme is main scheme for implementing said method, basic furnace structure, including body of heater 1, and fire door 2 is that liquid outlet is arranged on stove
Bottom is by furnace wall, this is easy to eluate collection, 2 times Founders of fire door to determine along the inflow die cavity of liquid track 4 is gone out going out liquid track 4, stove liquid
Type.Additionally, fire door 3 is opened up on the side wall of body of heater 1 is easy to filler, heat collector cavity 5 mainly collect stove liquid from coming out of the stove to flowing into die cavity this
The heat that one process is distributed, the end greatly of heat collector cavity 5 is thermal-arrest mouth, and small end is heat conduction mouth and is connected with the base plate 7 of pay-off 6, bottom
The heat conductivility of plate 7 is all good, and for transmitting heat and carrying furnace charge is newly added.Pay-off 6 adopts the adiabator of resistance to hot polymerization, can be side
Shape or tubular, it has charging aperture and a discharging opening, and discharging opening is connected with fire door 3 furnace charge is entered in stove.
Pay-off 6 ensure that feeding, in addition it is also necessary to which a fixed structure ensures that furnace charge can be entered smoothly in stove, i.e., fill including push-and-pull
11 are put, the push-pull device at fixed 11 passes through the preset hole 15 of pay-off 6 and end is hinged with the top of fire door 3.Push-pull device at fixed 11 is used
