Manufacturing process of nm450 wear-resistant plate
nm450 wear-resistant plate is made by hot rolling process. In the manufacturing process, the billet is first heated to a certain temperature, and then the billet is processed and pressed by rolling machinery. Finally, after cooling and surface treatment, nm450 wear-resistant plate was obtained.
The key to manufacture nm450 wear-resistant plate is to control heating temperature and rolling force. Reasonable heating temperature and rolling force can ensure the hardness and strength of the product, improve its wear resistance and impact resistance.
nm450 wear plate maintenance and maintenance
In order to maintain the good performance of the nm450 wear plate and extend its service life, regular maintenance and maintenance are required. below
nm450 wear-resistant plate is a kind of high-strength wear-resistant steel plate with excellent wear resistance and high strength characteristics. It is widely used in fields such as mining, construction, metallurgy and construction machinery to resist wear and impact. This article will introduce the basic characteristics of nm450 wear-resistant plate and its application in various fields.
