Abstract
The utility model relates to the thermal treatment unit of the large-scale Plate Steel of a kind of pit furnace process, belongs to heat treatment tooling field.The utility model comprises: hanger, hanger is respectively equipped with and installs the open holes of suspension hook and the erection opening for lifting by crane, also comprise: large-scale Plate Steel to be hung is provided with suspension ring.Described suspension hook is arranged on crossbeam through open holes nut and thin nut, and suspension ring are connected with large-scale Plate Steel by screw thread, and suspension hook is hooked on suspension ring, make large-scale Plate Steel vertical lifting on the utility model.Use of the present utility model, ensure that the vertical placement of the large-scale Plate Steel of different size, weight in pit furnace, and during thermal treatment, surface is vertical with gravity direction, and surface does not deform, thus the planeness on large-scale Plate Steel surface after achieving thermal treatment.
Description
Technical field
The utility model relates to the thermal treatment unit of the large-scale Plate Steel of a kind of pit furnace process, belongs to heat treatment tooling field.
Background technology
Usual employing car-type heat treating furnace is heat-treated large-scale Plate Steel, the chassis of car-type heat treating furnace pulls out from heat treatment furnace, large-scale Plate Steel is lain in a horizontal plane on chassis, again chassis is pushed in heat treatment furnace, although large-scale Plate Steel shove charge is convenient, but in heat treatment process, along with the rising of Heating temperature, the intensity of large-scale Plate Steel declines gradually, non-deformability reduces gradually, large-scale Plate Steel is by the effect of self gravitation, deform, unfairness is become through heat treated large-scale Plate Steel surface, also the planeness ensureing large-scale Plate Steel surface is difficult to by follow-up correcting process, have influence on the usability of large-scale Plate Steel the most at last.
Summary of the invention
The purpose of this utility model is the thermal treatment unit providing the large-scale Plate Steel of a kind of pit furnace process, this apparatus structure is simple, safe and reliable, shove charge is convenient, solve the problem on deformation of large-scale Plate Steel in heat treatment process, ensure that the planeness on large-scale Plate Steel surface, improve its use properties.
Technical solution:
The utility model comprises: hanger, hanger is respectively equipped with and installs the open holes of suspension hook and the erection opening for lifting by crane, also comprise: large-scale Plate Steel to be hung is provided with suspension ring.
Described hanger comprises: at least two vertical beams and at least two crossbeams, vertical beam and crossbeam form crisscross hanger, symmetrically arranged vertical beam has corresponding erection opening, symmetrically arranged crossbeam is respectively equipped with the open holes installing suspension hook, suspension hook is installed and is fixed by nut and thin nut.
The utility model is by the thermal treatment unit of the large-scale Plate Steel of a kind of pit furnace process, suspension ring on large-scale Plate Steel are hung on crossbeam, keep vertical at the medium-and-large-sized Plate Steel of heat treatment process, achieve the object that large-scale Plate Steel surface in heat treatment process is vertical with gravity direction, surface does not deform, the planeness on large-scale Plate Steel surface after ensure that thermal treatment.
Accompanying drawing explanation
Fig. 1 is utility model works state graph;
Fig. 2 is the utility model wiring layout.
Embodiment
The utility model comprises: three vertical beams 1 and three crossbeams 2 form crisscross hanger, the vertical beam on limit, two ends has corresponding erection opening 10, suspension ring 8 are respectively equipped with at the first large-scale Plate Steel 9 of large-scale Plate Steel 4, second and the third-largest type Plate Steel 11 top, the the second large-scale Plate Steel 9 being placed in limit, two ends is identical with the dimensional weight of the third-largest type Plate Steel 11, crossbeam 2 is respectively equipped with the open holes 3 of suspension hook 5, suspension hook 5 is fixed on crossbeam 2 by nut 6 and thin nut 7 by suspension hook 5.
During use, suspension ring 8 on large-scale Plate Steel are hung on suspension hook 5, suspension ring 8 are connected with large-scale Plate Steel by screw thread, make large-scale Plate Steel vertical lifting on hanger, winch to well formula heat treatment furnace in by erection opening 10 by this hanger with crane, large-scale Plate Steel keeps plumbness in well formula heat treatment furnace.
The large-scale Plate Steel that the utility model hanger hangs will make hanger keep horizontality, large-scale Plate Steel lifting region material can be used for the final performance detection experiment materials carrying out large-scale Plate Steel, and the threaded hole therefore installing suspension ring 8 does not destroy the integrity of large-scale Plate Steel.
Vertical beam 1, crossbeam 2:
Material: 4Cr5MoSiV1;
Heat treatment hardness: HRC 40 ~ 50;
Forging ratio: >=3;
Thermal treatment process: quenching temperature 1030 DEG C, oil cooling, double tempering, tempering temperature 580 DEG C, air cooling;
UT (Ultrasonic Testing): do not allow the defect being greater than ￠ 2 equivalent.
The large I of open holes 3 is determined according to the specification of large-scale Plate Steel, weight.
Suspension hook 5, nut 6, thin nut 7, suspension ring 8: selection standard part.
The large I of erection opening 10 is determined according to the specification of large-scale Plate Steel, weight and weight of the present utility model.
The utility model by the open holes on crossbeam, the large-scale Plate Steel of Liftable different size, weight.
Use of the present utility model, ensure that the vertical placement of the large-scale Plate Steel of different size, weight in pit furnace, and during thermal treatment, surface is vertical with gravity direction, and surface does not deform, thus the planeness on large-scale Plate Steel surface after achieving thermal treatment.
