Stainless steel welded pipe bright solid solution processing device

Abstract

The present invention relates to a stainless steel welded pipe bright solid solution processing device, including a support bottom base, a support upper base, and a solid solution furnace connected with a support upper base, wherein the support bottom base is provided with at least two sliding rails, and the support upper base can slide along the sliding rails. The solid solution furnace is provided with a heating zone, including a glass pipe, glass pipe seats and an induction heating coil, wherein the induction heating coil is wound around the middle of the glass pipe, the glass pipe seats are sleeved on two ends of the glass pipe, and the glass pipe seats are connected with a ring seat. The two ends of the glass pipe are sleeved with the glass pipe seats, the glass pipe seats are matched with the glass pipes of different diameters, the induction heating coil at the middle of the glass pipe is changed with the diameter of the glass pipe to meet the requirements of different pipes for induction heating coils, and to improve the quality of welded pipe solid solution treatment. When the solid solution pipe is not manufactured, the support upper base is moved to a non-working area; and when the solid solution pipe is manufactured, the support upper base is moved to a working area. Time is saved, and the smash possibillity of the quartz glass pipe in the disassembly process is prevented.

Description

technical field [0001] The invention relates to an online treatment device for stainless steel welded pipes, in particular to an online bright solid solution treatment device for stainless steel welded pipes. Background technique [0002] In the production process of stainless steel welded pipe, the welded pipe is rolled and welded by material plate. After welding, carbides are precipitated and lattice defects reduce the corrosion resistance of stainless steel. The corrosion resistance of stainless steel after solution treatment can be restored to the best state, so there are two common stainless steel tubes in the market, one is the rough tube without solid solution, and the other is the solid solution tube. In the prior art, when it is necessary to perform solution treatment on stainless steel welded pipes, a stainless steel welded pipe bright solution treatment device including a solution furnace 2 and a frame 1 is installed at the end of the abrasive belt machine. For th...

Problems solved by technology

[0005] When the heating zone in the prior art uses smaller or larger diameter quartz glass tubes, the quartz glass tubes do not match the ring seat and cannot be installed on the ring seat; since the quartz glass tubes in the solid solution furnace are all single caliber, the induction coil can only be one type, and there is no way to use quartz glass tubes with other diameters. When the diameter of the welded tube is relatively small, the electromagnetic induction coupling degree of the induction heating coil on the quartz glass tube to the welded tube is greatly reduced, which cannot be used for The solid solution treatment of the welded pipe is very good, and the solution treatment effect of the small welded pipe is not good, which will affect the quality of the product; to ensure the quality of the welded pipe after solid solution, it is necessary to use a smaller diameter induction heating coil. On the quartz glass tube, so it is necessary to use a matching quartz glass tube
