Layered titanium-aluminum steel composite strip coil material and preparation method thereof

Abstract

The invention discloses a layered titanium-aluminum-steel composite strip coil material and a preparation method thereof. According to the layered titanium-aluminum-steel composite strip coil material, an aluminum strip coil serves as a base material, a pure titanium strip coil is compounded on the upper surface of the aluminum strip coil, and a stainless steel strip coil is compounded on the lower surface of the aluminum strip coil; and the thickness ratio of the aluminum strip coil to the pure titanium strip coil to the stainless steel strip coil is 8: (1.5-3): (2-3). The production processflow comprises the steps of uncoiling, carrying out surface treatment, heating, rolling, coiling, annealing and obtaining a finished product coiled material, and the production processes in the process flow are continuous production line type production except annealing. The composite coiled material prepared by the method has the characteristics of being corrosion-resistant, wear-resistant, freeof toxicity, bacteria-resistant, and good in magnetic conductivity and thermal conductivity; and the interlayer binding force of the composite strip coil material is greatly improved.

Description

technical field [0001] The invention relates to the technical field of titanium composite materials, in particular to a layered titanium-aluminum-steel composite coil material and a preparation method thereof. Background technique [0002] The metal layered composite board is made of two or more metal plates with different properties through a special composite processing method. The metal layered composite board combines the respective advantages of two or more metal components, and can obtain Comprehensive properties not possessed by any single metal. At present, common metal clad panels in actual industrial production include: stainless steel clad panels, nickel / steel clad panels, copper / steel clad panels, titanium / aluminum clad panels, and titanium / steel clad panels. [0003] Titanium and titanium alloys are widely used in aerospace, petrochemical, marine and other fields due to their outstanding advantages such as high specific strength, low density, good toughness and...

AI Technical Summary

Problems solved by technology

[0003] Due to their outstanding advantages such as high specific strength, low density, good toughness and corrosion resistance, titanium and titanium alloys are widely used in aerospace, petrochemical, marine and other fields, but their cost is high, so how to reduce the titanium alloy layer The cost of layered materials is the key to whether titanium alloy layered materials can be widely used

At present, titanium-steel composite strip coils and titanium-aluminum composite strip coils are widely used, which mainly adopt methods such as explosive cladding, explosive-rolling cladding, and hot-rolling cladding to produce cladding of dissimilar layered metal materials, and industrial production thickness Above 4.0mm, the process is complicated, continuous production is impossible, the production efficiency is low, the product quality is greatly affected by the environment and other process conditions, and the product quality is unstable; and it will cause noise, vibration, smoke pollution, etc. to the environment.
