Titanium materials can be preheated, heated and cooled in sequence in the three-section continuous vacuum annealing furnace; the preheating furnace is separated from the heating furnace, and the manner that the integrated heating furnace heats the preheating chamber and the heating chamber is not adopted, so that energy can be saved, heat loss is avoided, energy consumption is low, and process control is stable.

Description

Three sections continuous vacuum lehres

Technical field

The utility model belongs to the HTFX technical field, is specifically related to a kind of three sections continuous vacuum lehres.

Background technology

In order to make metal works have needed mechanical property, physicals and chemical property, except the various moulding processs of choose reasonable, thermal treatment process is requisite often.The titanium material hot treatment is through changing its performance, does not change the shape and whole chemical ingredients of workpiece, but through microstructure that changes interior or the chemical ingredients that changes workpiece surface, gives or improves the workpiece use properties.

Lehre is to carry out the common equipment that the titanium material is handled, and when heat-treating, lehre need remain on elevated-temperature seal under the vacuum environment, need cool fast sometimes.Yet existing annealing furnace structure is all more single, and the titanium material needs repeatedly annealing, and energy consumption is than higher, and it is just cumbersome to operate like this.

Summary of the invention

The purpose of the utility model provides a kind of three sections continuous vacuum lehres, once anneal behind the titanium material entering lehre and just accomplish whole annealing process, and energy consumption is low.

The technical scheme that the utility model adopted is that a kind of three sections continuous vacuum lehres comprise being divided into bilevel body of heater; The body of heater on upper strata is connected with vacuum pump; The body of heater two ends on upper strata are respectively arranged with preceding fire door, back fire door, are provided with early gate and late gate in the body of heater on upper strata, and early gate and late gate are divided into preheating chamber, heating chamber, cooling room with the body of heater on upper strata; Be respectively arranged with cross track in preheating chamber, heating chamber, the cooling room; The lower floor of body of heater is respectively arranged with preheating oven and process furnace, and preheating oven is positioned at the below of preheating chamber, and process furnace is positioned at the below of heating chamber.

The characteristic of the utility model also is,

The outside wall surface of cooling room is provided with water-cooled tube.

Three sections continuous vacuum lehres of the utility model, the titanium material can carry out preheating, heating, cooling successively at lehre.In cooling room, can select air cooling or water-cooled, when needs adopted water-cooled, with feeding cold water in the water-cooled tube, the annealing to material had promptly been accomplished in cold water circulation cooling on the surface of cooling room.Preheating oven separates with process furnace, and does not adopt whole process furnace to preheating chamber and heating chamber operation, can save the energy like this, avoids the loss of heat, and energy consumption is low, and technology controlling and process is stable.

Description of drawings

Fig. 1 is the structural representation of three sections continuous vacuum lehres of the utility model.

Among the figure, 1. body of heater, 2. early gate, 3. late gate, 4. preheating chamber, 5. heating chamber, 6. cooling room, 7. before fire door, 8. back fire door, 9. cross track, 10. preheating oven, 11. process furnace, 12. vacuum pumps, 13. water-cooled tubes.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

The structure of three sections continuous vacuum lehres of the utility model; As shown in Figure 1; Comprise body of heater 1, body of heater 1 is divided into two-layer up and down, and the body of heater 1 on upper strata is connected with vacuum pump 12; Body of heater 1 two ends on upper strata are respectively arranged with preceding fire door 7, back fire door 8, and the body of heater 1 on upper strata is divided into preheating chamber 4, heating chamber 5, cooling room 6 by early gate 2 and late gate 3 again.In preheating chamber 4, heating chamber 5, cooling room 6, be respectively arranged with cross track 9, cross track 9 is by the motor traction control of outside.On the outside wall surface of cooling room 6, be equipped with water-cooled tube 13.The lower floor of body of heater 1 is respectively arranged with preheating oven 10 and process furnace 11, and preheating oven 10 is positioned at the below of preheating chamber 4, and process furnace 11 is positioned at the below of heating chamber 5.

Three sections continuous vacuum lehres of the utility model are the three-chamber lehre, and preheating chamber 4, heating chamber 5, cooling room 6 are built in the disjunctor stove, and the titanium material can carry out preheating, heating, cooling successively at three sections continuous vacuum lehres.At first, fire door 7 before opening is put into titanium material to be heated on the cross track 9 of preheating chamber 4, fire door 7 before closing.Open early gate 2 and late gate 3, owing to the titanium material need be annealed, so vacuumize in the bodies of heater 1 with the upper strata earlier with vacuum pump 12 under vacuum condition.Preheat through the material in 10 pairs of preheating chambers of preheating oven 4 then.Open early gate 2 then and material is delivered to heating chamber 5, material is annealed, after insulation for some time, open late gate 3 and material is delivered to cooling room 6 through cross track 9 through the high temperature of process furnace 11 through cross track 9.In cooling room 6, can select air cooling or water-cooled, when needs adopted water-cooled, with feeding cold water in the water-cooled tube 13, the annealing to material had promptly been accomplished in cold water circulation cooling on the surface of cooling room 6.

Preheating oven 10 left with process furnace in 11 minutes in the utility model, and did not adopt whole process furnace to preheating chamber 4 and heating chamber 5 operations, can save the energy like this, avoided the loss of heat, and energy consumption is low, and technology controlling and process is stable.
