Connection method for titanium plate and stainless steel plate

Abstract

The invention relates to a method for connecting a titanium plate with a stainless steel plate, which comprises the titanium plate, the stainless steel plate and a stainless steel strip welding material, and comprises the following steps: firstly, punching a plurality of small holes at the end part of the titanium plate and the end part of the stainless steel plate respectively; secondly, pulling a plurality of prepared stainless narrow strips into the small holes at the end parts of the titanium plate and the stainless steel plate so that the titanium plate is flexibly connected with the stainless steel plate; and thirdly, welding the stainless narrow strips with the welding material so as to weld a connecting piece of the titanium plate and the stainless steel plate. When a pure titanium plate strip is switched with stainless steel, the method is adopted to prepare certain number of the connecting pieces of the titanium plate and the stainless steel plate in advance; and according to production requirements, two ends of the connecting pieces can be welded with a titanium strip and a stainless steel leading strip so as to meet the requirements on collinear scale and the continuous production of titanium and stainless steel and the like. The method for preparing the connecting piece of the titanium plate and the stainless steel plate has a concise production process and improves the economic benefit.

Description

technical field [0001] The invention relates to the metallurgical manufacturing industry, in particular to a connection method for production switching between titanium plates and stainless steel plates on collinear equipment for titanium plates and stainless steel plates. Background technique [0002] Pure titanium coils and stainless steel strips have the same facilities in the cold rolling process equipment and can be collinear. On the collinear continuous production line (continuous annealing-pickling unit, grinding unit, bright degradation unit), steel coils are head-to-tail welded and continuously pass through various process equipment, stainless steel and other special steels (high-temperature alloys, nickel-based alloys, etc.) With good welding conditions, the belt can be threaded smoothly and continuous production can be realized. However, the welding performance of stainless steel and pure titanium is poor, and the connection cannot be solved with a general-purpos...

Problems solved by technology

However, due to the rivets at the joints of this process, it is easy to scratch the roller when it passes through the tension roller in continuous production, and it is easy to break the strip due to stress concentration during high-tension rolling.
