Problems solved by technology

For example, the expanded length of the mold cylinder for PTA with a diameter of Φ7,000mm reaches 21,980mm. If it is made of a titanium / steel composite plate with a length of less than 10,000mm, it will inevitably produce multiple welds, which will also increase the manufacturing cost and equipment. Security risks
[0004] The conventional production method of titanium / steel clad plates is direct explosive welding. Due to the limited size of thin titanium plates in the market, they need to be spliced. Defects such as multilayer cracking, local non-bonding, and interface melting will occur during explosive lamination. At the same time, these defects cannot be used. Ordinary welding methods for repair welding will directly lead to the scrapping of the entire composite panel due to partial unbonding, especially not conducive to the manufacture of large-scale, thin-clad, no-weld titanium-steel composite panels

Abstract

The invention discloses a preparation method of a titanium steel compound plate. The preparation method comprises the following steps of: firstly performing explosive welding on a titanium plate and asteel plate; and then hot-rolling the titanium plate and the steel plate to obtain the titanium steel compound plate. By performing explosive welding on the titanium plate and the steel plate, the bonding strength of a rolled blank after explosive compounding is high, and during hot rolling, the titanium / steel compound plate blank is heated and the rolling deformation is controlled at 4-7 times,so that the rolled titanium / steel compound plate has relatively high bonding strength and guarantees the thickness demands the titanium and steel.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and relates to a preparation method of a titanium-steel composite plate. Background technique [0002] Titanium has the characteristics of light weight, high specific strength, and corrosion resistance, while titanium / steel composite plates take into account the corrosion resistance of titanium and the high strength of steel plates, and the price is relatively low. They are widely used in petrochemical, electric power, hydrometallurgy, and caustic soda. and other industrial equipment and container manufacturing. [0003] With the continuous development of my country's economy, all kinds of equipment and containers are becoming larger and larger, which is reflected in the increasing length, diameter and area of ​​equipment or components. Therefore, the specifications and performance of the required titanium / steel composite plates Putting forward higher requirements, large-scale, thin clad...
