Abstract
The invention relates to the technical field of steel pipe preparation processes, in particular to a seamless steel pipe preparation process with a smooth surface, which comprises the following steps: the method is characterized in that a device for spraying the lubricant is arranged at a piercing plug during piercing, so that the lubricant is continuously sprayed out from the plug and sprayed between the plug and a steel pipe in the piercing process. When the process is used for producing the steel pipe, a layer of protective film is formed on the inner surface and the outer surface of the steel pipe through the lubricant, so that the cooling effect is achieved, the inner wall of the steel pipe is protected from being scratched, the lubricant is a mixture of glass powder, talcum powder and lubricating oil, the lubricant can be guaranteed to be better contacted with the steel pipe, meanwhile, heating, perforating, acid pickling and cold rolling and heat treatment of a bar blank are all carried out under a vacuum condition, air is prevented from entering the pipe wall, and the quality of the steel pipe is further guaranteed.
Description
Technical Field
The invention relates to the technical field of steel pipe preparation processes, in particular to a seamless steel pipe preparation process with a smooth surface.
Background
In the conventional steel pipe manufacturing process, blank preparation → acid pickling lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection, the inner surface of the steel pipe after piercing is rough because no special treatment step is provided during piercing.
Disclosure of Invention
The invention aims to solve the defect that the inner surface of a perforated steel pipe is rough due to no special treatment step during perforation in the prior art, and provides a seamless steel pipe preparation process with a smooth surface.
In order to achieve the purpose, the invention adopts the following technical scheme:
a preparation process of a seamless steel tube with a smooth surface comprises the following steps: the method is characterized in that a device for spraying the lubricant is arranged at a piercing plug during piercing, so that the lubricant is continuously sprayed out from the plug and sprayed between the plug and a steel pipe in the piercing process.
The lubricants used in the perforation were: the weight percentage of the mixture of the glass powder, the talcum powder and the lubricating oil is 1: 5.
heating, perforating, acid washing, cold rolling and heat treatment of the bar blank are all carried out under the vacuum condition.
Continuously spraying a lubricant between the cold roll and the steel pipe during cold rolling, wherein the lubricant is as follows: the weight percentage of the mixture of the glass powder, the talcum powder and the lubricating oil is 1: 5.
the preparation process of the seamless steel pipe with the smooth surface, provided by the invention, has the beneficial effects that: when the process is used for producing the steel pipe, a layer of protective film is formed on the inner surface and the outer surface of the steel pipe through the lubricant, so that the cooling effect is achieved, the inner wall of the steel pipe is protected from being scratched, the lubricant is a mixture of glass powder, talcum powder and lubricating oil, the lubricant can be guaranteed to be better contacted with the steel pipe, meanwhile, heating, perforating, acid pickling and cold rolling and heat treatment of a bar blank are all carried out under a vacuum condition, air is prevented from entering the pipe wall, and the quality of the steel pipe is further guaranteed.
