Abstract

The invention provides a heat treatment technique of a titanium-iron-stainless steel three-layered compound plate, and belongs to the field of material processing. The heat treatment technique comprises the following steps of directly placing a to-be-treated titanium-iron-stainless steel three-layered compound plate in a preheated heating furnace, heating with the furnace to 450 DEG C to 750 DEG C, and performing heat insulation, wherein the preheating temperature of the heating furnace is 180-220 DEG C, and the heating speed of the heating furnace is 500-550 DEG C/h; and taking out the heat-insulated titanium-iron-stainless steel three-layered compound plate, placing the titanium-iron-stainless steel three-layered compound plate in the air, and naturally cooling to a room temperature, thereby obtaining the heat-treated titanium-iron-stainless steel three-layered compound plate. The production method can effectively control the improvement of different mechanical properties (strength or plasticity) of the titanium-iron-stainless steel three-layered compound plate, can regulate and control different properties according to the application background requirements of different titanium-iron-stainless steel three-layered compound plate products, further increases the yield of the titanium-iron-stainless steel three-layered compound plate product, is low in production cost, and is high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a heat treatment method for a titanium-iron-stainless steel three-layer composite plate. Background technique [0002] The research and development intention of the titanium-iron-stainless steel three-layer composite board is to replace the new material of the ordinary iron pan. The base layer iron determines that the composite board has excellent thermal conductivity as a whole. Layer stainless steel can reduce the disadvantages of pure iron being too soft. The preparation of cookware is mainly produced by stamping process, and the plasticity of the plate directly determines the yield in the production process; the titanium-iron-stainless steel three-layer composite plate is not limited to the manufacture of cookware, because of its excellent corrosion resistance of the coating on both sides, it can also be used as A large number of structural parts are ...
