Embodiment

[0021] 1. Manufacture of TA1-Q235 rolled clad plate

[0022] TA1 and Q235 plates are obtained by the usual preparation method. The thickness of TA1 plate is 5mm, and the thickness of Q235 plate is 20mm. Cut 2 pieces of TA1 and Q235 plates of the same size, with a length of 1000mm and a width of 500mm. After grinding the TA1 and Q235 plates with abrasive belts, apply solder stopper in the middle of the two TA1 plates and stack them together, and put the Q235 steel plate on the outside of the TA1 plate for welding and assembly to form a Q235-TA1-TA1-Q235 four-layer plate structure . Put the sealed and welded composite plate into the heat treatment furnace, firstly keep it at 600°C for 60 minutes, then heat it to 850°C for 15 minutes, take it out and roll it directly, the reduction in one pass is 60%.

[0023] 2. Manufacture of TA2-Q235 rolled clad plate

[0024] The TA2 and Q235 plates are obtained by the usual preparation method. The thickness of the TA2 plate is 5mm, and the...

Abstract

The invention provides a manufacturing method of a titanium rolled composite plate and belongs to the material processing field. The method is characterized in that a titanium plate-steel plate combined blank manufactured by use of a common method is heated at two stages: firstly, the titanium plate-steel plate combined blank is put in a heating furnace and heated to the range of 500-700 DEG C; after heat preservation of 50-90 minutes, the titanium plate-steel plate combined blank is further heated to the range of 800-1000 DEG C, and then heat is preserved for 10-20 minutes so that the temperature of the internal titanium layer is lower than that of the external steel layer. The heating at the first stage is carried out at a low temperature and thus capable of reducing the degree of element diffusion between the titanium plate and the steel plate, while the heating at the second stage is carried out at a higher temperature and thus advantageous for hot rolling. In addition, the short-time high-temperature heating at the second stage aims at enabling the temperature of the internal titanium layer is lower than that of the external steel layer. Due to the adoption of the manufacturing method, element diffusion between the steel plate and the titanium plate can be retarded and the degree of an interfacial reaction can be reduced, and therefore, the titanium composite plate with higher bonding strength can be manufactured.

Description

technical field [0001] The invention belongs to the field of material processing, and in particular relates to the application of layered rolling composite plates. Background technique [0002] Clad steel plate is usually a new material composed of two or more metals combined in a layered form. Generally, mild steel and low alloy steel with low price and excellent processing performance are used as substrates, and materials with good corrosion resistance, heat resistance and wear resistance, or materials with certain special properties, such as stainless steel, copper and copper alloys are selected. , titanium and titanium alloys as cladding boards. Industrial composite steel plate is a layered composite material developed focusing on improving the environmental characteristics of the material. At present, the mainstream of clad steel plate development is stainless steel clad plate, copper alloy clad plate and titanium alloy clad plate, among which stainless steel clad pla...
