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 adopted in the present invention is as follows: including the lower stainless steel plate, the lower titanium plate, the isolation layer, the upper titanium plate, and the upper stainless steel plate stacked in sequence from bottom to top, and the upper stainless steel plate and the lower stainless steel plate are arranged through two The sealing strips around them are connected, and the upper stainless steel plate, the lower stainless steel plate, and the sealing strip cooperate to form a closed cavity, and the upper titanium plate, the isolation layer, and the lower titanium plate are set in the closed cavity, and there are reserved spaces in the closed cavity. The extension space of the upper titanium plate and the lower titanium plate. The present invention effectively avoids warped heads and buckled heads by adopting the method of stacking blanks and assembling blanks. In addition, the present invention can realize the hot rolling of titanium and stainless steel clad coil with a thin specification of ≤10mm by adopting the rolling of the steckel mill, 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...

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.
