Problems solved by technology

The above-mentioned cooling equipment solves the technical problem of using rapid injection and discharge of medium to realize quenching combined with immersion liquid spray quenching. Although it can also be applied to quenching and cooling of large-sized and heavy-weight quenched parts, it does not solve the problem of uniformity of quenching liquid temperature. question

Embodiment Construction

[0017] figure 1 The three-dimensional structure of the quenching tank of the large and medium-sized forgings according to the present invention is shown. The quenching tank is mainly composed of a tank body 1 , a submersible mixer 2 , a protective frame 3 and a frequency conversion controller 4 . The tank body 1 is in the shape of a cuboid tank, and submersible mixers 2 are respectively installed around the inner wall of the tank body 1 and at the bottom.

[0018] Two submersible mixers 2 are respectively installed on each long-side inner wall and wide-side inner wall of the tank body 1, and the submersible mixer 2 is in the middle position in the height direction of the inner wall on each side, and is located on the side in the length direction of the inner wall on each side. Two points in the middle of the trisection distribution of the inner wall.

[0019] 13 submersible mixers 2 are installed on the bottom of the tank body 1 (in order to make the figure clearly visible, o...

Abstract

The invention discloses a quenching tank for the large and medium size forging, comprising a body and submersible mixers which are mounted at the periphery and bottom of the inner wall of body. The submersible mixers are positioned at the middle in the height direction of each side of inner wall, at the two middle points of the trisected distribution of the inner wall in the length direction of each side inner wall. Thirteen submersible mixers are mounted at the bottom of the body and in the regular five-row and five-line lineup distribution. Each submersible mixer in the bottom of the body is connected with a frequency conversion controller by a line, the rotating speed of each submersible mixer can be controlled by the frequency conversion controller, thus a uniform temperature area is formed in the quenching solution in the body. The invention has simple structure, easy production, maintenance and use, and is mainly used for the quenching of large and medium size forging.

Description

technical field [0001] The invention relates to a metal heat treatment equipment, in particular to a quenching tank used for containing quenching liquid when large and medium-sized forgings are quenched and cooled. Background technique [0002] After forging and forming of large and medium-sized forgings, quenching treatment is usually required in order to obtain the expected structure and performance. The weight of the quenching liquid is about 10 times the weight of the workpiece, that is to say, a larger quenching tank is often needed to meet the quenching needs of large and medium-sized forgings. During quenching, if the temperature of the quenching liquid in the quenching tank is uneven, it will easily lead to uneven surface hardness of the forging, and in severe cases, defects such as stress deformation and cracking will occur, thereby affecting the heat treatment quality of the forging. [0003] The Chinese invention patent specification CN1556228A published on Decem...
