Problems solved by technology

This method can realize the connection between the titanium plate and the stainless steel plate, but the narrow strip connector needs to be bent 180° and welded to the steel plate or the titanium plate at the same time, the operation is more complicated, and there is a large internal stress in the bent narrow strip. 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 titanium plate pulls the stainless steel plate, the bottom connector is relatively protruding and the ends of the titanium plate and stainless steel plate are uneven, which is extremely dangerous. May subject device to scratches

example 1

[0028] First, prepare a stainless steel plate with a width of 1150mm, and cut 4 evenly distributed rectangular holes in the transverse direction at 90mm from the end of the stainless steel plate. The length and width of the rectangular holes are 150mm and 120mm respectively; then, from the waste pure titanium plate Cut 4 pieces of connectors with a width of 90mm and a length of 460mm; then, place the pure titanium plate under the stainless steel plate, and the end of the titanium plate can completely cover the rectangular hole on the stainless steel plate, and then place one end of the four pure titanium connectors Lay on the titanium plate in turn, and the other end is placed on the titanium plate through the rectangular hole; finally, use the pre-prepared titanium plate base metal welding wire to completely weld each connector and the titanium plate, and weld the stainless steel plate and the titanium plate. The end of the stainless steel plate at the lap shall be cut with a ...

[0031] First, prepare a stainless steel plate with a width of 1050mm, and cut 3 evenly distributed rectangular holes in the horizontal direction at 70mm from the end of the stainless steel plate. The length and width of the rectangular holes are 130mm and 100mm respectively; then, cut from the waste pure titanium plate 3 pieces of connectors, the width is 70mm, the length is 420mm; then, place the titanium plate under the stainless steel plate, and the end of the titanium plate can completely cover the rectangular hole, and then place one end of the three connectors on the titanium plate in turn, The other end is lapped on the titanium plate through the rectangular hole; finally, the three connectors are completely welded with the titanium plate by using the pre-prepared base metal welding wire of the titanium plate, and the welding of the stainless steel plate at the lap joint of the stainless steel plate and the titanium plate is completely welded. At that end, the cutting ar...

Abstract

The invention provides a connection method of a titanium roll and a stainless steel belt and a transition leading belt utilized by the connection method. The transition leading belt comprises a titanium board, a stainless steel board and a connection part. One end of the stainless steel board is arranged above the titanium board in a lapping mode, and one or a plurality of installation grooves are arranged in the stainless steel board of an overlapped portion. One end of the connection part is directly welded on the titanium board, and the other end of the connection part penetrates through the installation grooves and is welded on the titanium board so that the titanium board and the stainless steel board are connected together. The connection part and the titanium board are identical in materials, and the welding of the connection part and the titanium board is performed in an environment protected by inert gases. The connection method connects the transition leading belt between the titanium roll and the stainless steel belt and enables the titanium roll to be welded with the titanium board, and the stainless steel belt is welded with the stainless steel board. The connection method of the titanium roll and the stainless steel belt and the transition leading belt utilized by the connection method has the advantages that titanium-steel direct welding is avoided, continuous production of titanium rolls is ensured, and the utilized transition leading belt has good quality and enough strength so that the problems that the belt is broken and a device is scrapped to be damaged in a using process do not exist.

Description

technical field [0001] The invention relates to the metallurgical manufacturing industry, and more particularly, to a transition lead and a connection method used when the titanium plate is switched to the stainless steel plate on the co-linear equipment of titanium and stainless steel. Background technique [0002] Pure titanium coil and stainless steel strip can be produced on the same line. In the production line of continuous annealing and pickling unit of titanium coil, the steel coil generally needs to be welded continuously through various process equipment. Stainless steel and most steel grades and some special steels can pass through. Different welding methods ensure the welding quality, so that the belt can be passed smoothly and continuous production can be realized. However, the physical and chemical properties of stainless steel and pure titanium are significantly different. Relying on ordinary welding technology and general welding equipment cannot effectively ...
