The present invention has the advantages of high automation, high control precision, high operation reliability, simple maintenance, low cost, etc.

Description

[0001] Field: [0002] The invention relates to a lubricating system during section steel rolling, in particular to a graphite lubricating system for a seamless steel pipe rolling mandrel that uses graphite to lubricate the mandrel in steel pipe rolling production. Background technique: [0003] In the mid-1980s, the Swiss first used graphite to lubricate the mandrel in the steel pipe rolling production. At present, the graphite injection products of GRACO Company of the United States have a large share in this field. However, these graphite injection products have the following defects: 1. The degree of automation is low, the control precision is not high, and failures occur easily. 2. After the graphite deposits and scales, it is easy to block the pipeline, and it is also prone to failure. 3. High cost and high maintenance cost. Invention content: [0004] The purpose of the present invention is to provide a graphite lubrication system for rolling mandrels of seamless s...
