Before
stainless steel pipes enter the polishing process of the polishing machine, it is necessary to ensure that the quality of the stainless steel pipes used reaches certain standards. These standards will affect the quality of the polished stainless steel, so relevant standards should be strictly inspected and implemented. The following are the operating rules of the polishing process in a steel plant.
Before polishing the stainless steel pipe, polishers need to blow out all the stainless steel slag and water in the round pipe before polishing. When throwing square tubes, polish the tubes of the unloading rack. Be sure to use cloth to separate each layer of polishing to prevent flowers from being inserted into the tube surface. For completely polished pipes, there should be no wax on the stainless steel pipe head or pipe surface.
In order to prevent the stainless steel pipe from being damaged, especially the particularly curved pipe, it needs to be processed before polishing. In order to prevent large-volume quality problems, only good pipes within 5 branches can be used as machine pipes when adjusting the machine.
The pipe surface of stainless steel round and square pipes also has requirements, that is, the shape of the polished pipe must not be deformed or excessively bent after cooling. In addition, there are corresponding polishing brightness requirements, that is, when there is no problem with the quality of the steel strip, polishing should be based on clear brightness, and there should be no blackening, yellowing or whitening.
When hoisting flat-mouth semi-finished stainless steel pipes to the polishing table, double-headed hoisting pipes are required to prevent damage to the stainless steel pipes.
In addition, there are corresponding requirements and standards for the process data of stainless steel pipe polishing machines. That is, every time a hanging pipe is thrown, it can be polished and produced only if there is a process card. If there is no card, the quality inspection should be notified to replace the card before proceeding. Polished production. For damaged stainless steel pipes, as well as stainless steel pipes with quality problems, the stainless steel strip number and specifications must be written down. After confirmation by the packaging team leader, they can be taken to the scrap area or repair welding area for stacking. Every time a stainless steel pipe is thrown, it must be filled in according to the content of the process card. Stainless steel pipes that need to be polished repeatedly must also be confirmed. Every time a stainless steel pipe is thrown, it must be distinguished from another stainless steel pipe and cannot be mixed together.
In addition, the stainless steel pipe polishing machine process production schedule also has requirements and standards. According to the specifications of the production schedule, the polishing production of the adjustable machine is limited; each polishing machine must arrange polishing production according to the specification classification procedure. When there are too many semi-finished products, it is necessary to cooperate with the factory to work overtime to prevent blocking the stainless steel pipe production line.
