Rolling Mill Bearing--Heat Treatment Technology - Esgbearing.com

 


ESG Bearing is an expert of rolling mill bearings. The working conditions for steel mill bearings are demanding as they will face dust, steel particles, water, heat, high speed and high temperature, almost the toughest conditions compared to other industry.


​

Bearing with higher hardness will be more wear-resistant, but it will easily crack. Thus the bearing's working life will be reduced.

How to  avoid this problem, most bearing manufacturers do not dare to make the bearings too hard. Their hardness is around 58~60 HRC. ESG Bearing has the advanced heat treatment technology. The tenacity of the bearing is improved by 30% compared with ordinary bearings. The hardness of the bearing is also improved by 2 HRC, reaching about 60~61 HRC. Thus the bearing is more wear-resistant and won’t easily crack out, it has a much longer working life.

Reveal the skin care glass packaging plating process

图片
  Skincare glass packaging   plays a crucial role in the beauty industry, and its radiant appearance is often an important factor in attracting consumers' attention. However, the secret behind this is not only the glass itself but also the plating process hidden on its surface. In this article,   we will discuss in depth the plating process of skin care glass packaging , revealing the mystery behind it. Surface plating technology  is the plated parts (products) immersed in a potion containing metal ions to be plated and connected to the cathode, the other end of the potion placed on the appropriate anode (soluble or insoluble), after the DC, the surface of the plated parts that is precipitated a layer of metal film method. A simple understanding of the physical and chemical changes or combinations. It is commonly used in skin care glass packaging materials to add texture to the appearance and protective properties. This technique can involve coating the surface of t...
