Description

Speciality Quenching apparatus of rod parts cooling system
Technical field
The utility model relates to the cooling system of a kind of speciality Quenching apparatus of rod parts.
Background technology
Quenching is that metal works is heated to a certain proper temperature and keeps for some time, immerses immediately quick cooling metal heating processing technology in quenching media.Quenching can improve hardness and the wear resistance of metal works, so be widely used in modern mechanical manufacturing industry.Steel Rod is the main stressed member in construction work, belong to large-scale workpiece, the mechanical property that must guarantee the pull bar of each position or the different positions of same pull bar when thermal treatment is consistent, this will accomplish that all pull bars are evenly cooling when quenching, guarantee that hardening liquid is longitudinally fully stirred along pull bar, this not only needs there are enough hardening liquids, also needs to have enough large water circulating pump to carry out circulation stirring.The circulating quenching system and method that lacks speciality Steel Rod in existing quenching technology.
Utility model content
Based on this, be necessary the quench cooled problem for speciality Steel Rod, a kind of even system of the device of cooling and hardening liquid circulating quenching while realizing speciality Quenching apparatus of rod parts is provided,
A speciality Quenching apparatus of rod parts cooling system, at least comprises:
Quenching tank;
Overflow groove, overflow groove coupling is arranged at the end of quenching tank;
Spareslots, spareslots is connected with overflow groove by connecting tube;
Cooling tower, cooling tower is connected by circulating water pipeline with overflow groove, and recirculated water control valve is installed on circulating water pipeline;
Outdoor water circulating pump, is installed between spareslots and cooling tower, is used for that the water in spareslots is drawn into cooling tower cooling;
Indoor circulation water pump, is connected with spareslots, cooling tower and overflow groove respectively by circulating water pipeline, and recirculated water control valve is all installed on each circulating water pipeline;
Shower, is arranged on the bottom of quenching tank; And
Nozzle.
Preferably, described spareslots volume is 70m 3.
Preferably, described nozzle proportional spacing is arranged on shower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, each label is:
1 quenching tank
2 overflow grooves
3 recirculated water control valves
4 cooling towers
5 indoor circulation water pumps
6 outdoor water circulating pumps
7 spareslotss
8 circulating water pipelines
9 showers
10 nozzles
11 connecting tubes
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of even cooling system while realizing speciality Quenching apparatus of rod parts, comprises quenching tank 1, overflow groove 2, recirculated water control valve 3, cooling tower 4, indoor circulation water pump 5, outdoor water circulating pump 6, spareslots 7, circulating water pipeline 8, shower 9 and nozzle 10.
Quenching tank 1 is the mixed clay structure of a reinforcing bar at the rectangular parallelepiped of below ground, is of a size of 20000 * 2000 * 2700(unit: mm).
Overflow groove 2 is the cell bodies that mate with quenching tank 1, is located at the upper end of quenching tank 1.
Cooling tower 4 is connected with quenching tank 1 by circulating water pipeline 8.
Spareslots 7 is connected with overflow groove 2 and cooling tower 4 respectively by circulating water pipeline 8, on the circulating water pipeline 8 being connected with overflow groove 2 at spareslots 7, be provided with indoor circulation water pump 5, on the circulating water pipeline 8 being connected with cooling tower 4 at spareslots 7, be provided with outdoor water circulating pump 6.
Shower 9 is located at the bottom of quenching tank 1, and nozzle 10 proportional spacings are arranged on shower 9.
The utility model also provides a kind of even cooling method while realizing speciality Quenching apparatus of rod parts, and concrete mode of operation comprises two kinds of external circulating system mode of operation internal circulation system mode of operation.
External circulating system mode of operation is applicable to production continuously in enormous quantities, and specific works process is: before quenching, opening chamber's internal recycle water pump 5 and outdoor water circulating pump 6 and outdoor cooling tower 4, form waterway circulating.The pull bar of 850 ℃ of 10 tons of left and right is quenched rapidly in quenching tank 1, from each nozzle, upwards spray the current that flow velocity is 0.5-0.8m/s, the hot water producing from bottom to top enters overflow groove 2 along the direction of jet flow, and it is 70m that indoor circulation water pump is evacuated to outdoor volume the hot water in overflow groove 2 3spareslots 7, outdoor water circulating pump 6 is drawn into the interior cooling of cooling tower 4 the hot water of 7 li of spareslotss again, hardening liquid after cooling enters quenching tank 1 again, and spray by nozzle 10, the hot water producing enters overflow groove 2 again, so form circulation, quench fluid temperature is controlled at below 40 ℃ all the time, guarantee the quality of quenching.
Internal circulation system mode of operation is applicable to small serial production, and specific works process is: before quenching, close and lead to outdoor pipeline, only opening chamber's internal recycle water pump 5, forms waterway circulating.The pull bar of 850 ℃ of 5 tons of left and right is quenched rapidly into quenching tank 1, and the hot water of generation from bottom to top enters overflow groove 2 along the direction of jet flow.Indoor circulation water pump is withdrawn into the hot water in overflow groove 2 in quenching tank 1, and again sprays from the bottom nozzle 10 of quenching tank 1, realizes the circulation of hardening liquid.
Above-mentioned even cooling method and system while realizing speciality Quenching apparatus of rod parts, is applicable to 10 left and right, the steel pull bar of the longest 20m, and whole system is simple in structure, has not only guaranteed quenching quality but also saved the energy.
The above embodiment has only expressed embodiment of the present utility model, can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
