Embodiment Construction

[0025] A method for preparing a non-vacuum rolling titanium-steel clad plate, the specific steps are as follows:

[0026] 1) Select a carbon steel plate with a thickness of 100mm, a transition layer with a thickness of 1.5mm and a titanium plate with a thickness of 10mm, cut the plate to the required size, and do surface treatment;

[0027] 2) To prepare a release agent, take alumina powder or magnesium oxide powder and organic matter powder with a mesh size greater than 40 and mix with water in a ratio of (2-3): (1-2): 100 and stir evenly, and apply it on the titanium plate The non-bonded surface of the product should be left to dry or placed in an oven for drying, and the temperature of the oven should not be higher than 180°C;

[0028] 3) Place the side of the titanium plate coated with the release agent opposite, and fix it by spot welding;

[0029] 4) Stack the carbon steel plate, transition layer and titanium plate in sequence, and the stacking order is: carbon steel pl...

Abstract

The invention discloses a non-vacuum-state rolled titanium steel composite plate and a preparation method thereof. The titanium steel composite plate comprises a carbon steel layer, a transition layerand a titanium layer; the ability of compounding the transition layer with the carbon steel layer and the titanium layer is stronger than the ability of directly compounding the carbon steel layer with the titanium layer; and the transition layer can prevent part of elements in the carbon steel layer from diffusing to the titanium layer to form a brittle phase. According to the preparation methodof the titanium steel composite plate, the titanium steel composite plate is subjected to rolling compounding in a non-vacuum state by adopting an inert gas protection method, the reliability is high, the environmental requirement is low, and the non-vacuum-state rolled titanium steel composite plate is efficient and environment-friendly.

Description

technical field [0001] The invention relates to a composite plate and a preparation method thereof, in particular to a non-vacuum rolling titanium steel composite plate and a preparation method thereof. Background technique [0002] Titanium steel composite plate not only has the excellent corrosion resistance of clad titanium, but also has the strength and plasticity of base carbon steel. Compared with pure titanium plate, its production cost is greatly reduced, and it is an ideal material for manufacturing equipment used in corrosion-resistant environments. It is widely used in petrochemical, salt making, electric power, seawater desalination, marine engineering and other fields. [0003] At present, the main preparation methods of titanium-steel clad plates include explosive cladding, explosion-rolling cladding and rolling cladding. The explosive composite method has noise pollution and environmental pollution, is greatly affected by the weather, and has low production e...
