Production process of lubricant for cold drawn seamless steel tube

Abstract

The invention discloses a production process of lubricant for a cold drawn seamless steel tube, which is characterized by comprising the following steps of: 1. putting a certain amount of vegetable oil in a heating kettle and heating to 100-200 DEG C; 2. adding puffing powder in high-temperature vegetable oil, evenly stirring while adding the puffing powder till all the vegetable oil becomes solid particles; and 3. crushing the solid particles generated in the step 2 into powder which is the finished lubricant product, wherein the vegetable oil is palm oil. The lubricant produced by the invention has the advantages of environmental protection, high efficiency and good lubricating effect; and when used in the cold-drawing process of seamless steel tubes, the lubricant has the advantage of less consumption and can reduce the wear rate of mechanical molds and maintain the original characteristics of steel tubes, therefore, the steel tubes using the lubricant are beautiful in appearance and bright in color.

Description

technical field [0001] The invention relates to a lubricant production process, in particular to a lubricant production process for cold drawn seamless steel pipes. Background technique [0002] At present, the lubricating solution used in the cold drawn seamless steel pipe operation process is generally prepared by dissolving soap lubricants in water. The disadvantages of soap lubricants are: 1. Low fatty acid content, large dosage, and low efficiency; 2. Long melting time and many times of stirring, so the labor intensity of workers is high; 3. After a certain period of time, the soap solution becomes After the waste liquid is discharged, it will be discharged, and the residual oil, residual acid and residual phosphorus contained in the waste liquid will bring great pollution to the environment; 4. The phenomenon of iron sticking is obvious, which is easy to cause scratches and damage the inner and outer surfaces of steel pipes; 5. The steel pipe is soaked in soap lubrica...

The disadvantages of soap lubricants are: 1. Low fatty acid content, large dosage, and low efficiency; 2. Long melting time and many times of stirring, so the labor intensity of workers is high; 3. After a certain period of time, the soap solution becomes After the waste liquid is discharged, it will be discharged, and the residual oil, residual acid and residual phosphorus contained in the waste liquid will bring great pollution to the environment; 4. The phenomenon of iron sticking is obvious, which is easy to cause scratches and damage the inner and outer surfaces of steel pipes; 5. The steel pipe is soaked in soap lubricating liquid, the drying speed is slow, the site drips seriously, and the cleanliness of the working environment is destroyed; 6. The steel pipe treated with soap lubricating liquid has poor corrosion resistance and antirust performance
