A tempering device for skew rolling ball mill steel balls that can utilize waste heat

Abstract

The invention relates to the technical field of metal plastic forming technology and equipment, and provides a tempering device for skew-rolled ball milling steel balls that can utilize waste heat, including a frame, a thermal insulation shell, and a ball storage unit; the ball storage unit is installed in the thermal insulation shell, Including ball storage cylinder, air inlet cylinder, air outlet cylinder, ball inlet track, ball outlet mechanism, conical cooling cylinder, and arc-shaped bottom plate; the conical cooling cylinder is installed in the center of the bottom of the ball storage cylinder, and the heat enters the conical The heat dissipation cylinder is evenly released in the ball storage cylinder; the steel balls enter the ball storage cylinder through the ball entry track, and are evenly distributed around the conical heat dissipation cylinder. After the tempering process is completed, they are discharged from the device through the ball discharge mechanism. The invention has a simple structure and is easy to manufacture, and the steel balls are convenient to enter and exit. The conical cooling tube releases heat evenly, increases the overall heating area of ​​the steel balls, and has a good tempering effect. .

Description

technical field [0001] The invention relates to the technical field of metal plastic forming technology and equipment, in particular to a tempering device for cross-rolling ball mill steel balls that can utilize waste heat. Background technique [0002] Ball milling steel ball is the most commonly used grinding body in ball mills, and it is also the most consumed type of wearable parts in the milling industry. It has been widely used in building materials, metallurgy, mineral processing and chemical industries. It is of great significance to obtain steel balls with low cost and high performance. [0003] Compared with the traditional casting and forging processes, the production of ball milling steel balls by the cross rolling process has the advantages of high production efficiency, high material utilization rate, low production cost, and less environmental pollution. The production of high-performance cross-rolled balls requires a series of heat treatment processes, among...

AI Technical Summary

Problems solved by technology

Existing production lines mostly use well-type tempering furnaces for tempering treatment, and there are some shortcomings such as time-consuming and laborious process of steel balls entering and exiting, and uneven heating caused by the overall accumulation of steel balls.
