Lubrication problems in the production of straight seam steel pipes

Lubrication problems in the production of straight seam steel pipes Straight seam steel pipes need to use a product to match in the production process, that is, a glass lubricant, which was produced with graphite before using the glass lubricant, because at that time there was no such product in the market. Therefore, graphite can only be used as a lubricant, but under long-term use, everyone will find some problems, that is, the heat transfer efficiency of graphite is very high, and the thermal insulation effect is also very poor. In this way, the temperature of the mold will become very fast during the work, and it is easy to cause the wear phenomenon of the straight seam steel pipe, so that the product cannot be used for a long time. Therefore, manufacturers have been looking for a product that can replace graphite, that is, glass lubricants, but why should they be used? That is because there are many advantages of trolley furnaces. First, the heat transfer efficiency is relatively low, so that it can play a role of heat preservation and can also prolong the use time of the equipment.
