Description

TECHNICAL FIELD

[0001] The utility model relates to quenching treatment technical field, concretely is a kind of wear-resistant steel ball casting quenching treatment device. BACKGROUND

[0002] In the existing metal round bar rolling into ball process, high-temperature steel ball after furnace needs to be quenched and cooled to set temperature within set time, and quenching tank needs to be used.

[0003] Chinese patent CN220201992U discloses "steel ball quenching heat treatment device", which uses lifting type conical mesh cylinder to roll, and the steel balls are supported and discharged by rolling through inclined feeding and discharging shell after lifting, so that the discharge is convenient and the quenching efficiency is high.

[0004] During the operation of the device, due to the influence of the conical structure, the steel balls are easily concentrated to the wider side of the conical mesh cylinder under the joint action of centrifugal force and gravity during rotation. This accumulation phenomenon can cause the steel balls to be too dense in this area, affecting their uniform distribution in the mesh cylinder, and thus affecting the quenching effect. The steel balls need to be in full contact with the cooling medium to cool quickly during quenching, and the accumulation will limit the contact area of the steel balls with the cooling medium, causing the cooling speed of some steel balls to slow down, thereby causing problems such as inconsistent hardness and uneven internal stress distribution, ultimately affecting the quality and performance of the steel balls.

[0005] In view of this, we propose a wear-resistant steel ball casting quenching treatment device. UTILITY MODEL CONTENTS
