Method for rolling production of titanium and stainless steel composite coil through rolling mill

Abstract

The invention relates to a method for producing titanium and stainless steel composite coils by rolling in a rolling mill. The green body structure used in the present invention is: a lower stainless steel plate, a lower titanium plate, an isolation layer, an upper titanium plate, and an upper stainless steel plate stacked in sequence from bottom to top. The upper stainless steel plate and the lower stainless steel plate are connected by two The upper stainless steel plate, the lower stainless steel plate, and the sealing plate cooperate to form a closed cavity, and the upper titanium plate, isolation layer, and lower titanium plate are placed in the closed cavity, and there are reserved holes in the closed cavity. The extension space of the upper titanium plate and the lower titanium plate. By adopting the method of stacking and assembling blanks, the present invention effectively avoids warping and buckling phenomena. In addition, by using a Steckel rolling mill, the present invention can realize hot rolling of titanium and stainless steel composite coils with a thickness of ≤10mm, and can effectively prevent the temperature drop of the rolled piece during the rolling process.

Description

technical field [0001] The invention relates to a method for producing titanium and stainless steel composite coils by rolling in a rolling mill, which belongs to the field of metal composite hot coil production and can be used in the production of metal composite hot rolling. Background technique [0002] The base material of titanium and stainless steel composite plate can use various grades of stainless steel such as 304, 316L, 1Cr13 and duplex stainless steel, and the cladding material can use various grades of titanium such as TA1 and TA2; the material and thickness can be freely combined to meet The needs of different users; titanium and stainless steel composite panels are widely used in ocean purification, petroleum, chemical industry, salt industry, water conservancy and electric power and other industries. As a resource-saving product, titanium and stainless steel composite panels can reduce the consumption of precious metals and greatly Significantly reduce the pr...

AI Technical Summary

Problems solved by technology

Explosive cladding method can produce composite panels whose total thickness can reach hundreds of millimeters, but it is not suitable for producing thinner clad steel panels with a total thickness of less than 10mm, so the application field of titanium and stainless steel clad panels is limited; in addition, explosive composite utilization The energy production of explosives will cause vibration, noise and smoke pollution to the environment

The hot rolling method is affected by the rolling temperature of two different metal materials, titanium and stainless steel (titanium 850°C, stainless steel 1200°C), warpage and buckle during the rolling process (the elongation of the two different metals is different), and rolling Due to the influence of the temperature drop in the rolling process, the rolling failure is caused, so the hot rolling method is rarely used at present.
