Problems solved by technology

[0005] In order to meet the oil temperature requirements of the quenching oil and avoid its oil temperature being too high, the quenching oil is generally pumped out of the quenching tank, cooled by an external cooling tower and other equipment, and then returned to the quenching tank for recycling, so there is a large investment in peripheral equipment. , high cost of quenching treatment, uneven quenching, poor quenching quality, unstable grinding ball performance, etc.

Embodiment Construction

[0024] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings:

[0025] see Figure 1-Figure 3 : image 3 The protruding parts on the front and rear sides and the corresponding mixers are omitted.

[0026] The quenching tank includes a square tank body 1 with an open upper end. A cooling coil 2 is arranged on the side wall of the tank body 1 .

[0027] Each corner of the tank body 1 has a vertical protruding part 3 that protrudes and communicates with the inner cavity of the tank body 1, and each protruding part 3 is provided with a mixer.

[0028] Each mixer includes an associated power assembly and an agitation assembly.

[0029] The power assembly of each mixer comprises the support 41 that is arranged on the upper end of the corresponding protrusion 3 and stretches out, the vertical motor 42 that is installed on the outside of the support 41, the horizontal support bearing 43 that is arranged on the inside...

Abstract

The invention relates to an improved grinding ball quenching tank which comprises a tank body of which the upper end is opened, wherein the tank body is provided with at least one stirring machine, and the stirring machine comprises a power assembly and a stirring assembly which are connected; and the stirring assembly extends into the tank body. After the technical scheme is adopted, the stirring machine is started, and by utilizing the stirring and homogenizing effects of the stirring machine, the temperature gradient of quenching oil in the quenching tank is effectively reduced, so that the oil temperature is uniform, the quenching effect is better, and the properties (such as the indexes of hardness, density, and the like) of a grinding ball are greatly improved; and in addition, the cooling effect of the stirring machine effectively reduces the temperature of the quenching oil in the tank body, thus the temperature of the quenching oil cannot be too high so as to ensure that the possibility of burning of the quenching oil while the grinding balls enter the tank body is greatly reduced, equipment such as an external cooling tower, and the like can be omitted, and the investment of external equipment is reduced. In conclusion, when the quenching tank is used in a quenching process of the grinding balls, the quenching tank has the advantages of uniform quenching, good quenching quality, stable properties of the grinding balls and lower quenching treatment cost.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment, in particular to an improved grinding ball quenching tank. Background technique [0002] Grinding ball is a kind of wear-resistant metal sphere, which is widely used in powder preparation and ultrafine powder deep processing in industries such as cement building materials, metal mines, thermal power generation, chemical engineering, ceramic coatings, light industry papermaking, and magnetic materials. The special working environment requires the grinding ball not only to have sufficient strength and toughness, but also to have high hardness, density and good uniformity. Grinding balls are usually formed by casting or forging. After forming, heat treatment such as quenching and tempering is required to meet the requirements for use. The material of the grinding ball is mostly high chromium, medium chromium and low chromium alloy cast iron. [0003] The traditional grinding ball quen...
