Why use lubricants to make straight seam steel pipes

Straight seam steel pipes need to be matched with a product in the production process, that is, glass lubricant. Before using glass lubricant, it was produced with graphite, because there was no such product on the market at that time. Therefore, graphite can only be used as a lubricant, but after long-term use, everyone will find some problems, that is, the heat transfer efficiency of graphite is very high, and the heat insulation effect is also very poor. It will cause the heating rate of the mold to become very fast, which will easily lead to the wear 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 use them? It is because there are many advantages of trolley furnaces. First, the heat transfer efficiency is relatively low. It has a thermal insulation effect and can also prolong the use time of the equipment.
