I. Calendering and annealing Metal heat treatment process in which the work piece is heated to a predetermined temperature and cooled slowly after holding for a certain time.
The purpose of annealing is to:
(1) Improve or eliminate all kinds of structural defects and residual stresses caused by steel casting, forging, rolling and welding process to prevent deformation and cracking of the work piece.
② Soften the work piece for cutting.
(3) Refine the grain, improve the structure to improve the mechanical properties of the work piece.
(4) Prepare the organization for final heat treatment and pipe making
Second, the article points The stainless steel plate roll is the stainless steel plate roll, cut into the corresponding width, so as to carry out further processing and tube making, the process of slicing needs to pay attention to the slicing knife on the board roll scratch, the width and error of the slicing, in addition to the tube making process, the slicing of the mantle and burr is very important for the tube making process.
Three, welding Stainless steel tube is the most important process, stainless steel mainly using argon arc
welding and plasma welding, argon arc welding protection gas is pure argon, the main welding 3 mm below the stainless steel tube, plasma welding has a strong penetration, the main welding 5-8 mm stainless steel tube.
Four, welding path grinding Stainless steel pipe welding process, need to the appearance of the welding channel on the corresponding polishing and water cooling treatment, for the welding channel first water cooling, directly with the water mill grinding welding channel to smooth, generally according to the thickness of stainless steel pipe add 3-5 groups of water mill, welding channel grinding and dressing.
Five, the plastic Stainless steel welded pipe process is called extrusion production, all square pipe and rectangular pipe, are originally from the round pipe, through the production of the same circumference of the round pipe and then extruded into the corresponding square pipe and rectangular pipe, finally with the mold shaping and straightening.
Six, cutting Stainless steel tube for cutting process is relatively rough, most of them are cut with grinding wheel, cutting will produce cloak, need to be further trimmed; The other is band saw cutting, which is relatively accurate. There is also mantle heat treatment. For special purpose pipes, light heat treatment is needed to achieve a higher level of ductility.
Seven, polishing There are several processes for the surface treatment of the usual product tube and decorative tube, polishing, divided into 400#, 600#, 800#, and sand is divided into round sand and straight sand, 180#, 240#, 400#, 600#, 800#, respectively suitable for different levels of customer needs.
Eight, inspection Inspection, mainly check whether the outer diameter and thickness of the pipe are up to standard, whether the surface treatment is up to standard, whether the welding process is up to standard.
