Problems solved by technology

This method can realize the connection between the titanium plate and the stainless steel plate, but the narrow stainless steel strip used in the connection needs to be bent 180° and welded to the upper and lower sides of the steel plate at the same time. The weld seam (welding place) is prone to cracking or even breaking under the action of high temperature and high tension. In addition, when the stainless steel leader belt pulls the titanium plate, the bottom connector is relatively protruding and the ends of the titanium plate and stainless steel plate are uneven. There is a high risk of scratching the device

example 1

[0028] First, prepare an industrial pure titanium plate with a width of 1250mm, and cut four evenly distributed rectangular holes along the transverse direction at a distance of 90mm from the end of the titanium plate. The length and width of the rectangular holes are 150mm and 130mm respectively; Cut 4 pieces of connectors, the width is 95mm, and the length is 440mm; then, place the stainless steel plate under the titanium plate, the end of the stainless steel plate can completely cover the rectangular hole, and then place one end of the 4 stainless steel connectors on the stainless steel plate in turn , and the other end passes through the rectangular hole and is placed on the stainless steel plate; finally, use the pre-prepared stainless steel base material welding wire to completely weld each connecting piece with the stainless steel plate, and the stainless steel plate at the overlap between the stainless steel plate and the titanium plate The end of the machine is treated...

[0031] First, prepare an industrial pure titanium plate with a width of 1050mm, and cut three evenly distributed rectangular holes along the transverse direction at a distance of 80mm from the end of the titanium plate. The length and width of the rectangular holes are 140mm and 120mm respectively; Cut 3 pieces of connectors, the width is 85mm, and the length is 400mm; then, place the stainless steel plate under the titanium plate, the end of the stainless steel plate can completely cover the rectangular hole, and then place one end of the 3 stainless steel connectors on the stainless steel plate in turn The other end passes through the rectangular hole and rests on the stainless steel plate; finally, use the pre-prepared stainless steel plate base material welding wire to completely weld the three connecting pieces and the stainless steel plate, and the stainless steel plate and the titanium plate overlap. The end of the plate is treated with a cutting arc edge to reduce its s...

Abstract

The invention provides a connection method for a titanium coil and a stainless steel band and a transition leading band adopted by the connection method for the titanium coil and the stainless steel band. The transition band comprises a titanium plate, a stainless steel plate and a connecting piece, wherein one end of the titanium plate is arranged on the stainless steel plate in a lap joint mode, one or a plurality of installation grooves are formed in the titanium plate of an overlapped part, one end of the connecting piece is directly welded on the stainless steel plate, and the other end of the connecting piece penetrates through the installation grooves and is welded on the stainless steel plate so that the titanium plate and the stainless steel plate are connected together. The connection method is that the transition band is arranged between the titanium coil and the stainless steel plate and used for connecting the titanium coil and the stainless steel plate, wherein the titanium coil is connected with the titanium plate in a welded mode, and the stainless steel band is connected with the stainless steel plate in a welded mode. The connection method for the titanium coil and the stainless steel band and the transition leading band adopted by the connection method for the titanium coil and the stainless steel band have the advantages that titanium-steel direct welding can be avoided, when titanium coils are produced continuously, damage to equipment is reduced, the transition band has good quality and sufficient intensity, and in the process of using, the problems of band breakage and scratching of the equipment do not happen.

Description

technical field [0001] The invention relates to the metallurgical manufacturing industry, and more specifically, relates to a transition leader and a connection method used when the stainless steel plate is switched to the titanium plate on titanium and stainless steel collinear equipment. Background technique [0002] Pure titanium coils and stainless steel strips can be produced on the same line. In the production line of continuous annealing-pickling units for titanium coils, steel coils generally need to be welded head to tail and pass through various process equipment continuously. Stainless steel and most steel types and some special steels can pass through Different welding methods ensure the welding quality, so that the belt can be threaded smoothly and continuous production can be realized. However, the physical and chemical properties of stainless steel and pure titanium are significantly different, and the direct connection between titanium and steel cannot be eff...
