Manufacturing method for rolling titanium-steel composite plate

Abstract

The invention provides a manufacturing method for rolling a titanium-steel composite plate. A high-performance composite plate can be obtained through the steps of make-to-order conversion, basic shroud plate surface treatment, blank assembling, blank welding, vacuum pumping, heating (by a car bottom furnace, a pit type soaking furnace or a bell type furnace), descaling, rolling, straightening, plate separating, finishing, product inspection, surface treatment, packaging, goods delivering and the like. By adopting a composite blank making and vacuum pumping mode, a shroud plate is enabled to be in a sealed oxygen-free environment, a cladding steel plate can be protected to the maximum, and the cladding steel plate can be prevented from being subjected to high-temperature oxidation; by adopting the car bottom furnace, the pit type soaking furnace or the bell type furnace, the defect that the heating temperature of a steel pushing type or walking beam furnace is difficult to control can be avoided, the temperature control accuracy is higher, a titanium plate is enabled to be always rolled in an alpha phase region, and the composite quality and the surface quality are ensured; due to an innovated blank assembling, heating and rolling technology, the whole rolling preparation of a high-combination strength titanium / steel composite plate is realized, the online control on performance is realized, a follow-up thermal treatment technology is avoided, and the energy consumption and the production cost are reduced.

Description

Technical field [0001] The patent of the present invention relates to the technical field of the production of rolled metal composite panels, and more specifically, it relates to a method for manufacturing rolled titanium-steel composite panels. Background technique [0002] Metal titanium has strong corrosion resistance and has good stability in acid, alkali, neutral salt water and other oxidizing media, which is better than existing stainless steel and other non-ferrous metal alloys. Therefore, titanium is used in various chemical reactions. Containers, heat exchanger materials and anti-corrosion fields, but the disadvantage is that the cost is relatively high, especially when used as structural parts. The composite of titanium and high-strength and high-toughness structural steel into a laminated composite board can integrate the advantages of different materials, and give full play to the use characteristics of different materials, their comprehensive mechanical properties, p...

Problems solved by technology

[0012] However, due to the large difference between titanium and steel in chemical composition and physical properties, and titanium is easy to react with steel at high temperature, generating harmful substances, affecting the composite strength and composite rate, it is difficult to simply rely on ordinary rolling process Meet the performance requirements of two different materials

Therefore, if continuous production is to be realized, it is difficult to control the process of heating titanium-steel composite plates with continuous production furnaces such as pusher type and walking type. If a box type resistance heating furnace is used, the energy consumption is high and the efficiency is low.
