How to distinguish the quality of manganese steel screen wire material?
As a screening equipment, manganese steel screen is widely used in screening, filtration, dehydration, desliming and other operations in enterprises. Moreover, the screen made of manganese steel has strong bearing capacity and stiffness, and can be made into screen of various shapes. It is a screening product that everyone likes to use and is highly recognized.
When purchasing manganese steel screen, remember not to be greedy for small and cheap. The quality of all products is closely related to the price. The screen with low price cannot have good quality and materials. The technology of small workshops cannot be compared with that of large enterprises. Even some small manufacturers replace manganese steel wire with ordinary steel wire in order to make money. It looks like steel wire, but the essence is different, Because the screens of these materials are made of metallic iron, they are easy to rust after moisture, so screen manufacturers generally do anti rust treatment before leaving the factory. For example, the screen surface is sprayed with anti rust paint or anti rust grease. After such treatment, it is difficult for screening enterprises to distinguish, even if the technical discrimination takes a long time.
How to distinguish the material of manganese steel screen, the general method is to use magnets for high manganese steel, ordinary steel wire and the simplest method. The manganese steel screen made of 65Mn can be attracted by the magnet and the suction is still large, while the manganese steel wire woven screen made of manganese steel 13 has weak suction; The high manganese steel made of high manganese steel screen is an alloy and a mixture. Each substance in the mixture maintains its original properties. There is iron in the high manganese steel, so it can be magnetized, but it has no magnetism. Even if it is magnetized, its magnetism is much lower than that of other steel screens.
