Embodiment Construction

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention.

[0014] A composite plate, one side of the composite plate is rich in titanium carbide alloy steel, and the other side is a composite plate of low carbon steel or stainless steel, and the composite plate of rich accumulation titanium carbide alloy steel and low carbon steel or stainless steel Welded closed.

[0015] A method for preparing a composite board, comprising the steps of:

[0016] 1) In the process of smelting steel, titanium carbide alloy is added in a weight ratio of 10:1;

[0017] 2) The smelted metal material is centrifugally combined to cast the tube billet, so that titanium carbide is enriched on the inner side of the casting tube under the action of centrifugal force; the centrifugal casting temperature is 1500 ℃, the centrifugal speed is 1100 rpm, and the machine is stopp...

Abstract

The invention discloses a composite board and a preparation method thereof. A carbonized titanium alloy is added in the steel smelting process; centrifugation is conducted on the smelted metal material to compositely cast a pipe blank, heat treatment is conducted on the pipe blank which is formed by centrifugation and composite casting, the pipe blank is cut into arc blocks and subjected to forging and pressing, leveling and heat treatment, and an alloy plate with titanium carbide being accumulated on one side is prepared through forging and pressing and heat treatment; a low carbon steel plate or a stainless steel plate is selected to be buckled together with the prepared alloy plate, so that one side, where the titanium carbide is accumulated, of the prepared alloy plate faces up, welding and sealing are conducted on joint seams at the periphery to make a vacuum opening, and pressure sealing is conducted on the steel pipe after vacuumizing is conducted; a double-metal welding body issubjected to heating, forging and pressing repeatedly, so that the base plate and the alloy plate are firmly pressed and combined together, leveling is conducted, the inner surface and the outer surface are cleaned by using a turning lathe and a boring lathe, and thus the high performance composite board with one side being titanium carbide accumulated alloy steel and the other side being low-carbon steel or stainless steel is prepared. According to the prepared composite board, titanium carbide is accumulated on the surface of the composite layer, and the composite board is high in abrasionresistance, has a good welding property and toughness, and has enough adhesive strength.

Description

technical field [0001] The invention relates to the technical fields of metallurgy and steel rolling, in particular to a composite plate and a preparation method thereof. Background technique [0002] Existing clad plate manufacturing methods are complex and difficult to operate. For example, explosive cladding and rolling cladding are limited by clad plates, making it difficult to produce qualified clad plates, and macroscopic bonding gaps are likely to occur on the joint surface, which affects product performance. Contents of the invention [0003] The purpose of the present invention is to provide a composite board and its preparation method to solve the above technical problems. [0004] The present invention adopts the following technical scheme: a composite plate, one side of the composite plate is rich in titanium carbide alloy steel, and the other side is a composite plate of low carbon steel or stainless steel, the rich accumulation of titanium carbide alloy steel...
