Abstract
The utility model provides a novel heating element which can assure uniform cast heating zones, and the utility model is characterized in that graphite paper 1 with a required shape is connected with a power circuit via a graphite electrode 2. The utility model has the advantages of same heating effect as high-strength graphite, uniform cast heating zones, simple structure and easy assembly and disassembly, and the utility model is suitable for vacuum directional solidification devices.
Description
Technical field
The utility model relates to heating element, is a kind of novel heating element that is applied in the equipment such as heat treatment, casting specifically.
Background technology
In equipment such as heat treatment, casting, needed temperature reaches by heating element.For example, in the high temperature alloy foundry goods apparatus for directional solidification, to be cast in the casting mold of preheating in holding furnace after the alloy pig fusing, casting mold is being pulled away from holding furnace gradually with certain speed, casting mold is placed on the water mold, therefore can be in casting mold the formation temperature gradient, and temperature gradient is the key that metal forms the oriented crystallization tissue.In order to reach maximum temperature gradient, key is to make the casting mold thermal treatment zone evenly, stably remain on higher temperature.Usually need the temperature of the thermal treatment zone to reach about 1500～1600 ℃, this just requires the casting mold heating furnace to use good heater material (heating element), high-strength graphite is most widely used general at present, and the heater material that heats is best can reach the requirement of apparatus for directional solidification.But the high-strength graphite heater material generally adopts the machining mode in the apparatus for directional solidification, is processed into thin-walled graphite bucket from the assize inker, and cost is very high, and the process-cycle is long, be easy in the use because of mechanical collision impaired.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, and cost is low, does not need machining, guarantees casting mold thermal treatment zone uniform heating element.
The utility model provides a kind of novel heating element, it is characterized in that: the graphite paper made of shape 1 links to each other with power circuit by graphite electrode 2 on demand.Graphite paper 1 itself has the heats of traditional high-strength graphite, and can make the calandria of various sizes and multiple shape.
The novel heating element that the utility model provides, its graphite paper 1 can be fixed on the graphite electrode 2 with graphite bolt I3.
The novel heating element that the utility model provides, how right its graphite electrode 2 can be, and each right same polarity graphite electrode 2 usefulness copper electrode 4 links to each other, and copper electrode 4 usefulness graphite bolt II5 are fixed on each graphite electrode 2.
The novel heating element that the utility model provides can be with insulating sleeve 6 on its graphite electrode 2, links to each other with heating furnace body by insulating sleeve 6.
The thickness of the novel heating element that the utility model provides can be 0.1～5mm, so that by adjusting the size shape of graphite paper 1, reach the effect that changes thermal treatment zone length, diameter.
The advantage of the novel heating element that the utility model provides is: heats is identical with high-strength graphite, and cost is low, and is in light weight, guarantees that the casting mold thermal treatment zone is even, and it is convenient to use, change, and is particularly useful for vacuum oriented solidification equipment.

Fig. 1 is assemblied in structural representation in the apparatus for directional solidification casting mold heating furnace for the utility model;
Fig. 2 is assemblied in structural representation (vertical view) in the apparatus for directional solidification casting mold heating furnace for the utility model.
Embodiment
Below in conjunction with example in detail the utility model is described in detail.
The graphite paper 1 of used thickness 1.5mm, cutting reaches requirement size: 360 * 620mm, is rolled into ring-type (corresponding to the heating furnace cavity shape size of existing apparatus for directional solidification) then, is fixed on the graphite electrode 2 with graphite bolt I3 to link to each other with power circuit.Two pairs same polarity graphite electrode 2 usefulness copper electrodes 4 link to each other, and copper electrode 4 usefulness graphite bolt II5 are fixed on and use insulating sleeve 6 to be fixed in the heating furnace body 7 on each graphite electrode 2.
The utility model is replaced traditional high-strength graphite calandria, try out a kind of apparatus for directional solidification of developing in voluntarily, easy to use, heats is good, and maximum heating temperature can reach 1700～1800 ℃.
Claims (6)
