球磨机钢球硬度检测智能设备设计理论与方法

Design theory and method of intelligent equipment for hardness testing of steel balls in ball mills

球磨机钢球是球磨机装备的主要研磨材料,被广泛用于矿山、发电厂、水泥厂等。钢球的主要元素包括高铬钢球、高铬钢锻、低铬钢球、低铬钢锻等。钢球的硬度是体现钢球质量的主要指标,在其应用中要求检测出钢球表面硬度、球心硬度以及1/2处硬度、3/4处硬度。多年来,世界各国检测钢球硬度的主要方式是抽检,把钢球锯开静止放在洛氏硬度仪或理氏硬度仪上检测。这种检测方式耗时耗力,破坏性强,并且不能实现全检。全球的研究者和企业进行了多年研究,希望能找到一种全检的方法,但始终没有实现。文章通过在实际项目中的实践与近3年的研究,最终找到钢球全检的理论与方法。文章设计了一套智能化设备,结合涡流技术实现了至今为止全球科学家和企业无法解决的问题。这套装备的成功面市,将实现全球研磨机钢球全检的零突破,解决多年未决的一大难题。

The steel ball in the ball mill is the main grinding material used in ball mill equipment and is widely used in mines,power plants,cement plants,and other industries.The main types of steel balls include high chromium steel balls,high chromium steel forgings,low chromium steel balls,and low chromium steel forgings.The hardness of steel balls is the key factor reflecting their quality,and it is required to measure the surface hardness,core hardness,hardness at 1/2 position,and hardness at 3/4 position of the steel balls.For many years,the main method used by countries around the world to test the hardness of steel balls has been sampling,where the steel balls are sawn open and placed on a Rockwell hardness tester or a Brinell hardness tester for testing.This testing method is time-consuming,labor-intensive,destructive,and does not achieve complete inspection.Researchers and companies worldwide have been diligently exploring for many years in the hope of finding a comprehensive inspection method for steel balls,but an effective method has not been found.This paper,through practical application in real projects and nearly three years of research,has finally found the theory and method for comprehensive inspection of steel balls.The successful launch of this equipment will achieve a zero breakthrough in the global inspection of grinding machine steel balls,solving a major problem that has been unresolved for many years.
