Pack rolling production method of titanium steel composite board

Abstract

The invention discloses a pack rolling production method of a titanium steel composite board. The technical key point is that the pack rolling production method comprises the following steps that 1, a steel plate, a titanium plate and a pure iron plate are cut and polished for standby use; 2, the materials in the step 1 are combined to form a composite board blank, a separant is coated, a sealing ring is arranged on the outer part, guide pipes are welded in degassing holes, and the gas tightness is detected; 3, one guide pipe is connected with a vacuum pump, a vacuum thermocouple is mounted on the other guide pipe, and after vacuumizing, the guide pipes are sealed; 4, a composite board is heated, thermal insulation is performed, hot rolling and calendaring recombination is performed, and rolling is carried out for three times; 5, the step 4 is repeated until an ideal size is obtained; 6, the composite board is heated to 720-780 DEG C, the temperature is kept for 1-3 h, and diffusion annealing is performed; 7, the diffusion annealing is moved, the oxide layer of the surface of the composite board is calendered, and cold rolling and press polish are performed; 8, the composite board is heated again, the temperature is kept, and the diffusion annealing is performed; 9, the edge is trimmed and sealed to obtain a finished product. The method is free of the influence of seasons and environmental pollution, the production scale and the product specification are controllable, and the boundedness that only a thin plate can be manufactured by a continuous hot rolling manufacturing method is avoided.

Description

technical field [0001] The invention relates to a stack rolling production method of a titanium-steel clad plate. Background technique [0002] Titanium is a silver-white transition metal characterized by light weight, high strength, metallic luster, and good corrosion resistance (including seawater, aqua regia, and chlorine gas). Because of its stable chemical properties, good high temperature resistance, low temperature resistance, strong acid resistance, strong alkali resistance, high strength and low density, it is known as "space metal". However, its use cost is relatively high, especially when it is used as a structural component. In order to reduce the cost of use, it is usually made into a titanium-steel composite plate. Not only has the corrosion resistance of titanium, but also has the strength of ordinary steel plates, which greatly reduces the cost of use. [0003] The manufacturing methods of titanium-steel clad plates mainly include filler metal ingot rollin...

AI Technical Summary

Problems solved by technology

To sum up, the production method of titanium-steel clad plate in the prior art cannot meet the characteristics of low environmental pollution, controllable production specifications and product specifications at the same time, so it is necessary to improve the existing production process
