1 products heated by a sharp increase in the adhesion of each other, when the plate adhesion occurs outside the lubrication area will make the wire on the lubricant friction is not enough to provide lubricant into the mold mouth of the power, and then with the wire The jitter will bring out the vicinity of the mold mouth, when the coke block extrusion will have a new lubricant into the powder, this time out of the small nail cover for the size of the coke. These coughs are usually removed in a timely manner and will not cause much impact on the drawing process, but need to be removed in order to avoid excessive accumulation of further pull, which will produce some unnecessary waste of manpower.
2 products heat adhesion in the vicinity of the grinding mouth near the heat when the lubricant is further increased carbonization, these carbides adhere to the mold near the mouth, when the temperature increases with the carbonization of increased adhesion strength will increase the accumulation of these Accumulation of the coke strength of the colloid can not be with the movement of the wire and the formation of the friction and the removal will be blocked in the mold near the mouth, resulting in a good circulation of the lubricant, the subsequent lubrication powder can not be added in time to form a block Mold mouth of the plastic block, resulting in continuous lubrication failure, this time often manifested as a sharp damage to the mold leaving the quality of the wire was greatly affected, the production was forced to pause.
Calcium-based lubricants due to the impact of temperature on the smaller specific manifestations are not exactly the same
