Notes For High Tungsten Carbide Roll Ring

Tungsten carbide roll ring is a roll which is regard tungsten carbide and cobalt as materials and made by powder metallurgy method. There are some tips for using the tungsten carbide roll rings. Firstly the cooling water should be accurately rushed to the trough. Secondly you should check the groove wear after rolling. Finally stop to supply water until red steel completely finished or pile of steel rolling cooling.
When you need to change the tungsten carbide roll rings, you can change according to the following steps:
1.Review whether the specifications, roller diameter and processing of backup roll ring can meet production requirements.
2.Check all install equipment and tools to ensure they can work normally and carry the good roll rings to the assembly trolley.
3.Take the mill shaft protection sleeve after the mill stopped, use a hydraulic motor to change the roll ring. And remove it with special hoisting tool, then put to the assembly.
4.Use acetone and the cutting of toilet paper to clean mill shaft and roller ring gasket until clean without dirt.
5.After a reasonable set of roll gap, put the cleaning roller ring along the roller shaft and cone sleeve flat head until it touches the roll ring gasket.
6.Using special roller tool to make the roll ring pressing. The pressure indicated by  pressure gauge should be consistent in the removing and installing roll process.
7. Ensure the mill flush alignment of groove and has not been blocked.
