Description

TECHNICAL FIELD

[0002] The wear-resistant steel ball, also known as wear-resistant medium for grinding machine, is mainly used for grinding materials, so that the materials are ground finer. In the production process of the wear-resistant steel ball, the wear-resistant steel ball needs to be quenched to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of the steel. The quenching and cooling process of the wear-resistant steel ball is usually as follows: the wear-resistant steel ball is placed in a heating furnace for heating to reach the required quenching temperature; the heated wear-resistant steel ball is sent into a cooling box through a conveying system and rapidly immersed in a cooling medium for rapid cooling; in the cooling medium, the surface temperature of the wear-resistant steel ball rapidly decreases to form martensite structure, thereby improving the hardness and wear resistance.

[0003] After searching, a wear-resistant steel ball quenching and cooling device (Patent No. 2024207398019) is disclosed. The device includes a box filled with cooling medium. A filtering mechanism and a buffering mechanism are arranged in the box. The filtering mechanism includes a filter screen. A rectangular frame is arranged on the upper edge of the filter screen. Vertical rods are symmetrically arranged on the left and right sides of the rectangular frame. The number of the vertical rods is four. The buffering mechanism includes a horizontal plate on the left and an inclined plate upwardly connected to the right of the horizontal plate. A plurality of through holes are uniformly arranged on the upper part of the horizontal plate and the inclined plate. A plurality of blocking rods are uniformly arranged on the upper part of the inclined plate. A blocking plate is arranged on the edge of the horizontal plate except the inclined plate. The advantages of the device compared with the prior art are that the quenching quality of the same batch of steel balls is good, the buffering mechanism and the filtering mechanism are detachable, impurities in the box can be removed, and the quenching effect of the next batch of wear-resistant steel balls is avoided. However, there are still defects. Since the steel balls roll downward from top to bottom, the upper layer of cooling medium in the box is first contacted with the steel balls, resulting in that the temperature of the upper layer of cooling medium in the box is greater than that of the lower layer of cooling medium. The cooling medium in the box is in a static state and cannot flow.
