introduction:Metal tow chain that is steel and aluminum tow chain is originated from our great China,The specific time should be one year before liberation1948years。Because our great motherland is making progress,And the economy is booming,However, the lack of labor force has promoted the rapid development of automated machinery and equipment,However, the core component of automation is the steel and aluminum tow chain,Steel and aluminum drag chains become the core bones of automated machinery,Without it, even the most advanced equipment is a pile of scrap metal,So it is because of the importance of steel and aluminum towing chain that todays steel and aluminum towing chain products dominate one side,The huge development of investment space for many investors and enterprises to focus on the development and manufacturing of steel and aluminum chain。Mushrooming also refers to the steel and aluminum drag chain as if it blossomed all over the night。

introduction:Pit quality of mechanical greases 1、The importance of water resistance of grease Grease with good water resistance,The grease is guaranteed in the presence of water,Still can play a good lubrication effect,Grease with poor water resistance should not be used in parts in contact with water。For example, the continuous casting process in the steel rolling industry is characterized by a large amount of cooling water sprayed directly on the red-hot billet,At this time, not only a large amount of water enters the bearing,At the same time, a large amount of water vapor is produced and exists on the bearing surface,The grease is always in a state of high temperature and humidity,If the water resistance of the fat is not good, it is easy to be washed away,Loss of lubricity。
