Abstract
The utility model relates to a rapid cooling installation for workpieces in the furnace of isothermal annealing heat treatment production line which consists of a furnace body, a insulating course, a centrifugal fan and a wind cooling heat interchanger, wherein, the insulating course of the furnace body is separated into a cooling chamber and a hot air circulating chamber by a clapboard; workpieces are positioned inside the cooling chamber and the wind cooling heat interchanger is positioned inside the hot air circulating chamber; the centrifugal fan is arranged on the upper end of the hot air circulating chamber; furnace gas is inhaled by the centrifugal fan after passing the wind cooling heat interchanger and then furnace gas accelerates to blow to the workpieces from the top to cool the workpieces; at the same time, cold air enters into the centrifugal fan and cools down the wind cooling heat interchanger, and then the wind cooling heat interchanger transmits heat of the workpieces to the atmosphere. The cooling method prevents the cold air out of the furnace from entering the cooling chamber directly and the workpieces can be cooled uniformly in the cooling chamber, thereby protecting uniform hardness and uniform metallurgical structure of annealing workpieces.
Description
Technical field
The utility model relates to a kind of Equipment for Heating Processing, refers in particular to a kind of interior workpiece quickly cooling device of stove of isothermal annealing heat-treatment production line.
Background technology
At present, after heat tracing, workpiece needs fast cooling to a suitable temperature to the blank isothermal annealing of mechanical component (or claiming normalizing).Make austenite that pro-eutectoid does not take place on the one hand and change, make workpiece temperature can not reach the bainite transformation district again simultaneously.Present equipment is that a typhoon machine of outer setting is introduced cooling room with cold wind, cold wind is blown on the workpiece from the bottom of workpiece, because speed of cooling is too fast, inhomogeneous cooling is even, can cause the temperature at part workpiece corner place to drop to the bainite district, cause at last that workpiece hardness after the isothermal annealing is inhomogeneous, metallographic structure is defective, the product easy deformation after later process processing difficulties and the thermal treatment.Existing equipment is unfavorable for reducing production costs and improving the quality of products.
Summary of the invention
It is suitable that the purpose of this utility model provides a kind of speed of cooling, workpiece quickly cooling device in the uniform stove of cooling area.
Technical solution adopted in the utility model is: it comprises body of heater 1, thermal insulation layer 2 and 3, centrifugal fan 5, vent-pipe 9, vapor pipe 10, gas blower 11, also comprises air cooling heat exchanger 8.The internal surface of body of heater 1 is provided with thermal insulation layer 2, be divided into cooling room and hot air circulation chamber by thermal insulation layer 2 formed furnace space by a dividing plate 4, be fixed on the top of body of heater 1 behind the bottom installation thermal insulation layer (3) of centrifugal fan 5, one group of impeller 6 is installed on the wheel shaft of centrifugal fan 5 and is arranged in the coaming plate 7, multilayer air cooling heat exchanger 8 is indoor by the hot air circulation that the interlayer support is installed in impeller 6 belows, the inlet end of air cooling heat exchanger 8 links to each other with gas blower 11 by the vent-pipe 9 that pools together, and its outlet side communicates with outdoor by vapor pipe 10.The inlet end of cooling room links to each other with a process furnace 15, and its exit end communicates with a constant-temperature oven 16, is provided with the guide rail 12 of a perforation process furnace 15 and constant-temperature oven 16 in the cooling room, and workpiece 14 is placed on the guide rail 12 by a charging tray 13.
The beneficial effects of the utility model are: because body of heater is divided into cooling room and hot air circulation chamber, workpiece is placed in the cooling room, air cooling heat exchanger places hot air circulation indoor, the top of hot air circulation chamber is equipped with centrifugal fan, the furnace gas that centrifugal fan will pass through air cooling heat exchanger sucks and quickens to blow to workpiece from top, makes the workpiece cooling; After feeding freezing air by gas blower simultaneously air cooling heat exchanger is lowered the temperature, air cooling heat exchanger is sent to the heat of workpiece in the atmosphere.This type of cooling has prevented that the outer freezing air of stove from directly entering cooling room, workpiece can evenly be cooled off at cooling room, thereby all even metallographic structure of hardness that has guaranteed annealing workpiece is even.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model comprises the body of heater 1 of resistance to air loss steel construction, by thermal insulation layer 2 and 3, centrifugal high temperature resistant blower fan 5, vent-pipe 9, vapor pipe 10, gas blower 11 that lagging material is built into, also comprise the air cooling heat exchanger of making by high temperature material 8.The internal surface of body of heater 1 is provided with thermal insulation layer 2, be divided into cooling room and hot air circulation chamber by thermal insulation layer 2 formed furnace space by a dividing plate 4, the top of centrifugal fan 5 is provided with thermal insulation layer 3, both are fixed on the top of body of heater 1 together, one group of impeller 6 is installed on the wheel shaft of centrifugal fan 5 and is arranged in the coaming plate 7, two layers of air cooling heat exchanger 8 are indoor by the hot air circulation that the interlayer support is installed in impeller 6 belows, the inlet end of air cooling heat exchanger 8 links to each other with gas blower 11 by the vent-pipe 9 that pools together, and its outlet side communicates with outdoor by vapor pipe 10.The inlet end of cooling room links to each other with a process furnace 15, and its exit end communicates with a constant-temperature oven 16, is provided with the guide rail 12 of a perforation process furnace 15 and constant-temperature oven 16 in the cooling room, and workpiece 14 is placed on the guide rail 12 by a charging tray 13.
Have pyritous workpiece 14 and be transported to cooling room by process furnace 15, the furnace gas that centrifugal fan 5 will pass through air cooling heat exchanger 8 sucks and quickens to blow to workpiece 14 from top, makes the workpiece cooling; Simultaneously, furnace gas is walked heat from working parts strap, and workpiece temperature is reduced, and the temperature of furnace gas raises.The furnace gas that temperature has raise is by air cooling heat exchanger 8 coolings, and sucked by centrifugal fan 5, quicken the workpiece of after-blow in cooling room through centrifugal fan, after going round and beginning again, make workpiece drop to the temperature of regulation equably in a time cycle, the temperature of this regulation is measured by temperature measuring equipment.Workpiece behind the uniform decrease in temperature is transported to isothermal chamber and carries out isothermal processes, simultaneously, the new heated work pieces of one dish is transported to cooling room by process furnace again carries out cooling air blower 11 freezing air is sent into air cooling heat exchanger 8, and with air cooling heat exchanger heat discharge outdoor by vapor pipe 10 after being converted into warm air.At this moment, be cooled again chamber internally heated furnace gas heating and its temperature is raise of air cooling heat exchanger, and feed behind the freezing air once more with the air cooling heat exchanger cooling, be sent in the atmosphere until the heat of air cooling heat exchanger workpiece.This type of cooling has prevented that the outer freezing air of stove from directly entering cooling room, workpiece can evenly be cooled off at cooling room, thereby all even metallographic structure of hardness that has guaranteed annealing workpiece is even.
