Abstract

The utility model discloses a deep well formula thermal treatment tooling, relates to a heat treatment of materials equipment, specificly relates to the biggest deep well formula thermal treatment tooling who uses the height that can guarantee the stove. It solves existing deep well quenching furnace hoist and mount part to advance when carrying out thermal treatment in the stove, because of heat preservation and the actual height that hookup frock hoist produced, has limited the biggest problem of using the height of stove. The utility model discloses a furnace body to reach the bell that constitutes by bell panel and bell heat preservation, characterized by: be equipped with a heat preservation section of thick bamboo that is greater than bell heat preservation height on the outer circumference of bell heat preservation. The utility model discloses the department increases mobilizable heat preservation height at the fire door, and the bell heat preservation and the frock hoist pad that will need not quench rise, does not occupy the zone of heating of stove, use the utility model discloses afterwards, the hoist does not fall into the zone of heating, and the hoist warp for a short time, can sparingly change 5, 000 yuan of left and right sides of hoist cost every year.

Description

A kind of deep-wall type thermal treatment process equipment

Technical field

The utility model relates to a kind of material heat treatment equipment, particularly relates to the maximum a kind of deep-wall type thermal treatment process equipment using height that can ensure stove.

Background technology

For nonstandard thermal treatment deep-well stove, according to quenching service requirements, bell position is all designed with certain thickness thermal insulation layer, and thermal insulation layer adds insulating powder by insulating brick and refractory brick and is built into, and thermal insulation layer height is generally no more than 500mm; In heat treatment process, deep-well quenching furnance adopts bell tying up tool to install thermal insulation layer additional, suspender lower link suspension ring lift part and enter in stove to heat-treat, because of thermal insulation layer and the actual height connecting tool lifting appliance generation, the space of 1000 to 1500mm generally can be occupied when falling in stove, limit the maximum use height of stove, therefore do not reach expection and use height; In addition, during thermal treatment, tool lifting appliance falls into heating zone, and suspender is out of shape, and suspender uses three months and just must change, and adds cost.

Summary of the invention

The purpose of this utility model is for above-mentioned deficiency, and a kind of maximum use height that can ensure stove proposed, suspender can not fall into heating zone, and suspender distortion is little, cost-saving a kind of deep-wall type thermal treatment process equipment.

Technical solution of the present utility model is: thermal treatment process equipment comprises body of heater, and the bell be made up of bell panel and bell thermal insulation layer, it is characterized in that: on the excircle of bell thermal insulation layer, be provided with the heat-preservation cylinder being greater than bell thermal insulation layer height.

Heat-preservation cylinder described in technical solution of the present utility model forms thermal insulation layer housing by two concentric cylinders, has lagging material at these two concentric cylinder central filler.

The internal diameter of the thermal insulation layer housing described in technical solution of the present utility model is consistent with the internal diameter of body of heater.

The utility model increases moveable thermal insulation layer height at fire door place, by do not need quench bell thermal insulation layer and tool lifting appliance pave, do not occupy the heating zone of stove, stove stopping property of the present utility model does not change, normal heating heats up, when heat treated part length is no more than 5500mm, position, effective heating area in stove can be hung; After installing thermal insulation layer additional, suspending equipment can be made overall outside heating zone, and during work, frock temperature is relatively low, can keep higher intensity, improve the security of use; Can not be out of shape because of long-time heat, affecting workpiece normally comes out of the stove, and substantially increases the work-ing life of frock simultaneously.Stove of the present utility model meets the heat-insulating property of stove, does not affect quenching temperature and heat-up time; Heat treated workpiece can be hung in effective heating area, and workpiece heat temperature reaches quenching technology temperature; The utility model handling are simple, can use flexibly according to practical condition.Use after the utility model, suspender does not fall into heating zone, and suspender distortion is very little, and suspender used three months and just must change in the past, only need regularly replace middle connection suspension ring now, can save replacing suspender cost about 5,000 yuan every year.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, the utility model comprises suspension ring 1, punching axle 2, bell panel 3, bell thermal insulation layer 4, hanging crossbeam 7, perforation crossbeam 8, heating zone 9, body of heater 10, thermopair 11, bell panel 3 and bell thermal insulation layer 4 form the bell of thermal treatment deep-well stove, resistance wire is had as heating zone 9 at body of heater 10 internal fixtion, body of heater 10 internal fixtion has the thermopair 11 of detected temperatures, be located at the punching axle 2 in bell panel 3 and bell thermal insulation layer 4 centre hole, and be fixed on the suspending equipment that the hanging crossbeam 7 of punching axle 2 lower end and perforation crossbeam 8 form thermal treatment deep-well stove, the excircle of the bell thermal insulation layer 4 of bell is provided with a heat-preservation cylinder, and the height of this heat-preservation cylinder is greater than the height of bell thermal insulation layer 4, and the height of heat-preservation cylinder can be determined according to the length of part to be heated, heat-preservation cylinder forms thermal insulation layer housing 5 by two concentric cylinders, and the steel plate that thermal insulation layer housing 5 can adopt two pieces of 10mm thick rolls and is welded into two concentric cylinders, has lagging material 6 at these two concentric cylinder central filler, the internal diameter of thermal insulation layer housing 5 is consistent with the internal diameter of body of heater 10, and the lagging material 6 of thermal insulation layer housing 5 two cylinder central filler is made up of refractory brick, insulating brick and insulating cotton, during part shove charge to be heated, the upper end of punching axle 2 hangs on driving crossbeam by suspension ring 1 suspension ring, punching axle 2 is through the centre hole on the bell be made up of bell panel 3 and bell thermal insulation layer 4, part to be heated hangs over the hanging crossbeam 7 of punching axle 2 lower end and bores a hole on crossbeam 8, by suspension ring 1, part to be heated is sling, the lower periphery making to be connected to the heat-preservation cylinder that bell is made up of thermal insulation layer housing 5 and lagging material 6 is placed on the upper periphery of body of heater 10, now, part to be heated is placed on the heating zone in body of heater 10, namely suspending equipment is hung crossbeam 7 and perforation crossbeam 8 and is just arranged on non-power hot-zone in body of heater 10.
