Abstract
The utility model belongs to the technical field of ohmic resistance heating, concretely relates to resistance melting furnace, this resistance melting furnace comprises furnace body (1), heating member (2), crucible (3) and bell (4), and its characterized in that heating member (2) comprise with the anastomotic plate body of crucible appearance (5) and high resistance alloy electric heating element (6) in plate body (5). The utility model provides a resistance melting furnace is small, light in weight, heat accumulation loss is little, the cold furnace intensifies fast, the empty stove loss is little, the thermal efficiency is high, can be used to the smelting of non ferrous metals such as aluminium, magnesium, antimony, zinc, plumbous.
Description
The utility model belongs to the technical field of Ohmic resistance heating, is specifically related to a kind of resistance melting furnace.
The present resistance melting furnace that uses, be in furnace shell with welding such as band steel, angle steel, steel plates, be built into heating clamber with the heat-insulation and heat-preservation material, be placed with crucible in the heating clamber, the non-ferrous metal that needs fusing is housed in it, and the electrical heating elements of being made by high-resistance alloy is being arranged in putting around heating clamber on the brick.Heating separates with crucible to be set up, in the heat radiation mode, heating crucible, the crucible temperature outside is raise, and the temperature difference of formation and crucible inboard is main mode with the heat conduction again, with heat from inboard, crucible lateral, and, the metal temperature in the crucible is raise gradually until fusing by interior side direction metal transmission heat, reach the work purpose.Because the crucible and the heating of resistance melting furnace are separately set up, the heating of employing external-heat, the heating heating crucible is based on radiation mode, the conversion efficiency of electric energy and radiant energy will be subjected to the influence of factors such as raw-material physics, chemical property and operating temperature of heating and off-energy, so brought the body of heater volume big, weight is big, the accumulation of heat loss is big, black furnace heats up slow, and empty stove loss is big, the not high a series of shortcoming of the thermal efficiency.
The purpose of this utility model is to provide a kind of body of heater volume little, in light weight, and the accumulation of heat loss is little, the black furnace quick heating, and empty stove loss is little, the resistance melting furnace that the thermal efficiency is high.
The purpose of this utility model is to realize like this, resistance melting furnace described in the utility model is made up of body of heater, calandria, crucible and bell, calandria is made of the plate body and the inner high-resistance alloy electrical heating elements of installing of plate body that coincide with the crucible external form, calandria overcomes the shortcoming that calandria brings with the radiation mode heating crucible mainly with the conduction pattern heating crucible.
Advantage of the present utility model is that described resistance melting furnace volume is little, in light weight, the accumulation of heat loss is little, the black furnace quick heating, empty stove loss is little, the thermal efficiency is high.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing, the structure chart of the utility model resistance melting furnace.
With reference to accompanying drawing, the utility model resistance melting furnace is made of body of heater (1), calandria (2), crucible (3) and bell (4), and calandria (2) is by the plate body (5) and the formation of the high-resistance alloy electrical heating elements (6) in the plate body (5) of coincideing with crucible (3) external form.Plate body (5) is fastened on the crucible (3) with bolt (7).The material of plate body (5) is according to the serviceability temperature difference, adopts that cast iron aluminising, cast iron are aluminized, in the middle silicon spheroidal graphite cast-iron, rare-earth and high chromium nitrogen nickel steel, high-temperature alloy steel any.
When the utility model resistance melting furnace uses, high-resistance alloy heating (6) heating plate body (5), the plate body (5) that coincide with crucible (3) external form are with thermaltransmission mode heating crucible (3), the temperature outside of crucible (3) is raise, heat transmits heat from the outside of crucible (3) by the metal in the interior side direction crucible (3), metal temperature in making crucible (3) raises and fusing, thereby reaches the work purpose.
Claims (3)
1, a kind of resistance melting furnace of being made up of body of heater (1), calandria (2), crucible (3) and bell (4) is characterized in that calandria (2) is by the plate body (5) and the formation of the high-resistance alloy electrical heating elements (6) in the plate body (5) of coincideing with the crucible external form.
2, resistance melting furnace according to claim 1 is characterized in that plate body (5) is fastened on the crucible (3) with bolt (7).
3, resistance melting furnace according to claim 1, the material that it is characterized in that plate body (5) can be that cast iron aluminising, cast iron are aluminized, middle silicon nodular cast iron, rare-earth and high chromium nitrogen nickel steel, high-temperature alloy steel.
