The specific embodiment
By reference to the accompanying drawings heating in vacuum furnace structure of the present utility model is illustrated.
Vacuum furnace of the present utility model, this heating furnace includes body of heater 1, periphery at described body of heater 1 is provided with heat tape 6, the periphery of heat tape 6 is provided with heat-insulation layer 7, be respectively equipped with seal cover 2 at the two ends of described body of heater 1, the seal cover 2 of described body of heater 1 one ends is provided with air-filled pore 3, is provided with aspirating hole 4 at the seal cover 2 of the other end of described body of heater 1, and the center is provided with temperature-measuring port 5 on the seal cover 2 of the body of heater 1 of aspirating hole 4 one ends.Be vacuum state or filling inert atmosphere in described body of heater 1.
Described heat tape 6 is body of heater 1 outside heating tape of twining parcel, and described heat tape is wrapped in the outside of described body of heater, is used for heating.Described temperature-measuring port 5 is connected with the thermocouple that is placed on body of heater 1 inner thermometric.
As shown in Figure 1, vacuum furnace of the present utility model, this heating furnace comprises body of heater 1, there is seal cover 2 at the two ends of body of heater 1, air-filled pore 3, the aspirating hole 4 reserved respectively on the seal cover 2, the center is provided with temperature-measuring port 5 on the seal cover 2 of the body of heater 1 of aspirating hole 4 one ends.Temperature-measuring port 5 is the airtight copper pipe of an end, is used for placing the thermocouple (not shown), can play a protective role to thermocouple, and thermocouple is in copper pipe 5 inside.The body of heater 1 outside heat tape 6 that twines, the outside heat-insulation layer 7 that twines heat-insulation and heat-preservation in heating tape.The material of selection high insulating effect is wrapped in the outside of described heat tape 6, is used for insulation, such as asbestos, to reduce energy loss.
Heat treated as required is steel pipe, and body of heater 1 adopts the steel pipe of Ф 245mm * 12mm * 4m, and the density of steel pipe is high, is easy to reach high vacuum.The steel pipe TBE can be selected preferably oval button of sealing property.During use, the steel pipe that will heat-treat is put into body of heater 1, contacts with body of heater 1 in order to prevent steel pipe to be processed, causes the inequality of being heated, and can place the slow objects of heat conduction such as rockwool blocks below body of heater 1, and the steel pipe that be heated is separated with body of heater 1.After putting steel pipe into, screw thread is smeared thread compound at two ends, to reach preferably sealing effectiveness, then sealed at both ends lid 2 is tightened sealing, then thermocouple is inserted in the copper pipe of reserving temperature-measuring port 5, and copper pipe can play the effect of protection thermocouple.
Twine the heat tape 6 of crawler type pottery in body of heater 1 outside, heat tape 6 uses 220V temperature-controlled power case to carry out temperature control.Asbestos are twined again as heat-insulation layer 7, conserve energy in the outside of heat tape 6.At first will be evacuated in the body of heater 1 by aspirating hole 4 during use, in body of heater 1, be filled with inert gas by air-filled pore 3 again, atmosphere of inert gases situation as required can be taked repeatedly to vacuumize, the method for filling with inert gas guarantees that other gases that do not have in the body of heater 1 exist.
In order to prevent body of heater when working, temperature distortion can be laid bracing frame below body of heater.
When vacuum furnace of the present utility model uses, can according to temperature in the stove of thermocouple measurement, adjust firing rate and the heating-up temperature of heat tape 6.
The utlity model has following advantage:
Body of heater outside all with the winding heating plate, body of heater is heated evenly, items is out of shape little.
2. this apparatus structure is compact, and floor space is little, and cost is low, and is easy to maintenance.
