Abstract
Disclosed is an energy-saving melting intermediate frequency furnace which comprises: a furnace shell, an intermediate frequency coil, a lightweight refractory furnace lining, a graphite melting internal furnace, a graphite insulation internal furnace, an internal furnace channel and a valve. The energy-saving melting intermediate frequency furnace dismantles a melting channel, eliminates phenomena of channel breakage and blockage, realizes production and starting at any moment, freely controls the power-on and power-off time and saves the national energy compared with the current induction line frequency furnace. The intermediate frequency furnace reduces the melting cost and maintenance expense and improves the work efficiency. Meanwhile, the energy-saving melting intermediate frequency furnace also has advantages of simple structure and low building cost.
Description
Technical field
The utility model relates to a kind of intermediate frequency furnace that can carry out melting to copper and alloy thereof.
Technical background
Using the induction main frequency furnace, copper and alloy thereof are carried out melting is method of smelting commonly used at present, is widely used.Existing main frequency furnace mainly is made of parts such as furnace shell, furnace lining, channel, induction coil, iron cores, wherein channel be use with the copper of institute melting and alloy phase thereof with the ring (solid) that forms of pouring metal melt.Its operation principle is: after main frequency furnace energising after-current enters induction coil, make the very big electric current of the inner generation of channel by electromagnetic induction, because of channel is a short-circuited conducting sleeve, thereby make the channel fusing.Thereby make the heat energy in the channel pass to burner hearth interior copper and alloy thereof rapidly, finally make copper and alloy melting thereof in the stove.
But the problem that the melting of above-mentioned main frequency furnace exists has: one, be prone to disconnected ditch phenomenon.Because in this main frequency furnace channel is arranged, also will switch on when not producing keeps temperature in the stove.Otherwise copper liquid temperature decline can appear in outage solidifies channel, is prone to disconnected ditch phenomenon from newly sending electric capacity, and whole body of heater can be scrapped.Two, choking phenomenon easily takes place.More because of impurities when the melting copper scrap, the channel model is when the heating fusing, and these impurity are concentrated in and occur choking phenomenon together.These choking phenomena can make the channel (or channel model) in the fusing not plan a successor and can not turn-on current, make its fusing of can not generating heat, and cause whole body of heater to be scrapped.Must roll over stove and take out former channel (stove cooling generally need 2-3 day) and the new channel of brickwork use again, cause the waste on temporal loss and the fund, increase the melting cost.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and this equipment has been cancelled channel, and the phenomenon that disconnected ditch just can not take place and block channel provides a kind of blowing out at any time and blow-on, saves state's source appliance.
The purpose of this utility model is achieved through the following technical solutions: a kind of energy saving fusing intermediate frequency furnace comprises: furnace shell, intermediate frequency coil, lightweight refracrory furnace lining, graphite melting flue, graphite insulation flue, flue passage, valve.Wherein graphite melting flue charging aperture one side opens wide, and the flue passage that connects graphite melting flue and graphite insulation flue goes out to hang down 5CM than connection graphite melting flue mouth being connected graphite insulation flue mouth place.
After adopting the utility model, when copper and alloy thereof melt, enter graphite insulation flue in the graphite melting flue, make finished product by hauling machine then by the flue passage.Because do not have channel in the graphite melting flue, can be when work finishes powered-down, metal remained solution can be discharged by valve.Therefore this energy saving fusing intermediate frequency furnace is compared folding except channel with existing induction main frequency furnace, get rid of and resolve ditch, generation choking phenomenon, can accomplish to produce at any time start at any time, free hold energising, power-off time, saved national energy, reduce the melting cost, reduced the expense of maintenance, improved an operating efficiency.The intermediate frequency furnace of this energy saving fusing simultaneously also has simple in structure, the characteristics that construction cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation
The specific embodiment
As shown in Figure 1, the utility model energy saving fusing intermediate frequency furnace, comprise furnace shell 1, intermediate frequency coil 2, lightweight refracrory furnace lining 3, graphite melting flue 4, graphite insulation flue 5, flue passage 6, valve 7, wherein graphite melting flue 4 end charge doors open wide.
Open power supply during work, add copper and alloy thereof from graphite melting flue 4, electric current produces heat by intermediate frequency coil 2, heat makes the copper and the alloy melting thereof of graphite melting flue 4 by the heat transmission of lightweight refracrory furnace lining 3, graphite, solution flows into graphite insulation flue 5 by flue passage 6, make finished product by hauling machine then, need repair and when stopping production for a long time as device fails, open the valve 7 of graphite insulation flue 5 bottoms and get rid of residue a little copper and alloy solution thereof, valve-off 7, last powered-down.
