Abstract
The utility model relates to a kern type melting resistance furnace, belonging to the technical field of industrial resistance furnaces. The utility model is applied for aluminium, magnesium, zinc, tin, lead and other non-ferrous metal with low melting point and the melting or the smelting thereof. The utility model is a kern type melting resistance furnace which is composed of a furnace body 6, a melting chamber 5 whose inner part has no crucible, a closed type electric heater 3 which has direct contact and is surrounded by metal to be melted and smelted, a furnace cover 2 and a metal protective hood 1 and is used for heating and melting. The utility model has the advantages are of big heat transfer area, much heat quantity transfer, few heat energy loss, high speed of temperature raising, short melting time, high productive efficiency, simple structure, few auxiliary device, small size, small occupation of land, low use cost and repair cost, etc. The heat efficiency of the utility model can reach 85-90%.
Description
The utility model belongs to industrial resistance furnace technical field, is specifically related to a kind of core type fusing resistance furnace.
The resistance melting furnace that low melting point non-ferrous metal such as China's fusing now or melting aluminium, magnesium, zinc, tin, lead and alloy thereof use, owing to following reason:
1. the heat transferred in the stove mainly relies on the thermal radiation of electric heating element;
2. what crucible was arranged not only wants first heating crucible, and fusing work can not be carried out continuously, has increased the loss of energy;
3. some area of electric heating element is directly towards the wall at burner hearth or melting tank top.Make effective heating surface (area) (HS reduce, the heat of transmission is also with regard to corresponding minimizing;
4. the inwall of burner hearth, because of being subjected to the direct radiation temperature height of electric heating element, refractory material, the use amount of heat-barrier material just must increase, and causes the increase of the volume and weight of body of heater, and the accumulation of heat loss of body of heater and surface radiating loss are increased;
5. electric heating element will contact for a long time with high temperature air in stove, causes the damage that high-temperature oxydation produces easily, and its working life is shortened;
6. after cooling is waited in necessary blowing out, just can carry out the fault repair of electric heating element or more renew the work of electric heating element, it is slow to bring loss to cause present resistance melting furnace to exist the interior programming rate of stove to the output of production time and product, the time of heat fused is long, the production efficiency and the heat efficiency are all low, the shortcoming that heat energy loss wastes energy greatly etc.
The purpose of this utility model is to provide a kind of and is dissolving the indoor crucible that do not have, and needs fusing or the molten metal of practicing directly the electric heating element contact to be surrounded the core type fusing resistance furnace that carries out heat fused.
The utility model comprises body of heater 6, melting chamber 5, closed electric heating device 3, bell 2, metal skirt 1.Fig. 1 is its structural representation.Below in conjunction with Fig. 1 the utility model is illustrated.In furnace shell 7 with steel plate and shaped steel welding, build or be cast into melting chamber 5 by laying bricks or stones with refractory material, after closed electric heating device 3 is installed on the bell 2, bell 2 is installed in the top of melting chamber 5 again, make the lower end of closed electric heating device 3 put in the bottoms in the melting chamber 5 and the power-line terminal of upper end is equipped with metal skirt 1 after stretching out bell 2 and power line being connected, also have charge door 4, metal liquid stream to export 8 on the body of heater 6.
Closed electric heating device 3 described in the utility model, be a kind of with thermo electric material through after the insulation and encapsulation process of insulating material, directly surperficial uncharged plate body of casting with the heating resisting metal liquation or the cylinder that fin is arranged.
The thermo electric material that closed electric heating device 3 described in the utility model uses is the resistance wire that metal electric heating material or non-metal electrothermal material are made, resistive band, Elema, Si-Mo rod or graphite rod etc.
The advantage of this practical firewood type is not have crucible in melting chamber, the metal that needs fusing or melting, directly contact surrounds closed electric heating device, heat transfer area is big, can adopt heat conduction, thermal convection, three kinds of heat transfer types of thermal radiation simultaneously metal to be heated, programming rate is fast, fusing time is short, production efficiency is high; Do not need heating crucible, not direct heat fused chamber interior walls, heat energy loss is little, heat efficiency height, the heat efficiency can reach 85-90% under furnace insulation facility good state.
Simple in structure, auxiliary device is few, volume is little, take up an area of less, cost is low, usage charges and maintenance cost are low, when fusing or melting, running into closed electric heating device damages, need only change the bell of having adorned appropriate closed electric heating device, connect power line, dissolve or molten practice work and just can continue and carry out, need not wait until that stove is cold, strive for the time.
Thermo electric material does not contact with the furnace high-temperature air because of sealed, and can not produce high-temperature oxydation and damage, long service life not only, and also surperficial power value is big, the use amount of having saved thermo electric material.
Do not have crucible in the melting chamber, just do not had the runout accident of crucible burn through generation and the various manpowers that cause thus, material resources, the waste of financial resources yet.
Heat transferred in the melting chamber no longer is based on thermal radiation, need not be coated with infrared radiating coating specially on the closed electric heating device, not only saves infrared radiant material but also save the work that is coated with infrared radiating coating.
In a word, the utlity model has heat efficiency height, programming rate is fast, fusing time is short, production efficiency is high; Advantages such as volume is little, cost is low, cost of use is low, easy to maintenance, long service life are a kind of desirable melting units.
