Embodiment example 1

[0051] Implementation case 1. TA2 titanium slab clad rolling process

[0052] The first step: choose TA2 titanium slab as the substrate, and determine the specifications as follows: 150*1070*1070mm. Two pieces of industrial pure titanium plates are used as cladding plates, and the specification is 3*1070*1070mm.

[0053] Step 2: Polish the base plate and cladding plate with an impeller wheel with a mesh number of 80#. After polishing, no oil stains, milling steps, inclusions, cracks and other defects are allowed on the surface of the base plate, that is, the TA2 titanium slab. The maximum depth of pits is allowed 10mm, the aspect ratio should be less than 1:3. Defects such as inclusions, peeling, pits, and holes are not allowed on the surface of the cladding plate, that is, the pure titanium plate.

[0054] After polishing, wipe the surface of the slab and pure titanium plate with alcohol or acetone.

[0055] The third step: the spot welding of the substrate and the claddin...

Abstract

The invention provides a method for producing a titanium and titanium alloy plate by utilizing a welding cladding-rolling technology. The method comprises the following steps that 1, a base plate anda doubling plate are determined; 2, the base plate and the doubling plate are subjected to surface treatment; 3, spot welding fixing of the base plate and the doubling plate is conducted; 4, the edgeparts are sealed and welded; 5, the base plate is subjected to turn-over treatment; 6, hot treatment is conducted; 7, rolling treatment is conducted; and 8, whether the titanium and titanium alloy plate is qualified or not is inspected. According to the method for producing the titanium and titanium alloy plate by utilizing the welding cladding-rolling technology, the cladding-rolling cost of a titanium or titanium alloy plate blank is reduced, the cladding efficiency is improved, and the rolling yield of the titanium or titanium alloy plate is increased; and by adopting the method to clad-roll the titanium or titanium alloy plate blank, the phenomena of surface cracks and edge cracks can be effectively reduced, the plate blank cladding efficiency is greatly improved, the cladding cost isreduced, and the final yield is increased.

Description

technical field [0001] The invention relates to the field of processing titanium and titanium alloy plates, in particular to a method for producing titanium and titanium alloy plates by welding cladding rolling technology. Background technique [0002] Titanium or titanium alloy slabs are prone to surface cracks and edge cracks during the rolling process, which greatly reduces the yield. By covering the surface of the alloy slab with a protective layer, the phenomenon of cracks and edges of the alloy slab during the rolling process can be effectively controlled, and the amount of grinding can be significantly reduced, and the yield of products can be improved. [0003] At present, the method of explosive cladding is generally used to achieve cladding of titanium alloy slabs. Although explosive coating has the advantages of high adhesion and high bonding strength, in actual production, explosive coating is greatly affected by weather conditions, which is not environmentally ...
