[0045] The manufacturing method embodiment of this stainless steel cold-rolled clad steel plate is the following steps in sequence:

[0046] 1. Match

[0047] The stainless steel 0Cr18Ni9 and ordinary carbon steel plate 10Al that meet national standards and technical requirements will be inspected, and the stainless steel plate and steel plate will be combined according to the final product and rolling requirements. Two 0Cr18Ni9 stainless steel cladding plates and one 10Al ordinary carbon steel plate form a group .

[0073] The manufacturing method of this stainless steel cold-rolled clad steel plate differs from Example 1 in two points. The first is that the materials of the base plate and the A-side doubler plate and the B-side doubler plate are different, and the second is that the hot-rolled steel plate is solution pickled in step eight. Finally, there are cold rolling and cold rolling solution pickling, and then inspection and finishing. The first eight steps of this embodiment are the same as those of the embodiment, that is, 1. Matching; 2. Welding carbon steel strips around the doubler plate; 3. Grinding; 4. Explosive...

Abstract

A method for manufacturing a compound steel plate of stainless steel includes the following steps in turn: I, matching two stainless steel plates with a common carbon steel plate and carrying out fitting up according to the demands of a final finished product and rolling; II, welding carbon steel strips on the surrounding of the compound plate: welding the common carbon steel strips with a thickness of 6-8mm and a width of 60mm on the surrounding of the non-junction surface of the compound plate; III, polishing: using a sander to remove the impurities like oxide on the junction surface; IV, explosion welding: welding the compound plate of A surface on a basic plate firstly, and then welding the compound plate of B surface in an explosion way; V, fault detection: using an ultrasonic defectoscope to carry out fault detection; the area junction rate between the compound plate and the basic plate is not less than 99 percent; VI, carrying out defected weldseams on the surrounding fault; VII, carrying out hot rolling on the compound steel plate; feeding the compound steel plate into a hot milling roll to be rolled into a hot rolling compound steel bend with a thickness not more than 3mm; VIII, carrying out hot rolling, solid solution and acid cleaning on the steel plate and finally finishing the steel plate. The manufacture method of the invention can be used for manufacturing the compound steel plate of stainless steel with a total thickness of 0.8mm to 2mm.

Description

technical field [0001] The invention relates to a method for manufacturing a stainless steel clad steel plate. Background technique [0002] Stainless steel clad plate is a new type of material that is energy-saving and environmentally friendly. At present, the direct explosion method is mainly used to produce stainless steel medium-thick steel plates in China. It is mainly used in petrochemical, water conservancy, and salt production. The characteristics of this production method require that the clad layer is thicker (≥ 2mm), which limits the application range of the stainless steel clad steel plate. In light industrial machinery, food, cooking utensils, construction, decoration, welded pipes, railway passenger cars, medical and health, environmental protection and other industries, what is more needed is a stainless composite steel cold steel with a total thickness of less than 2mm, especially less than 1.2mm. Rolling of thin steel sheets and strips. The stainless steel...
