Embodiment 1

[0020] In this embodiment, Q345R is selected as the base layer material, and 316L is selected as the compound layer material. The specifications of the finished composite board are: (47+3)+(27+3) thickness×2040 width×12000 length mm, of which the thickness of Q345R is 47 and 27mm respectively, and the thickness of stainless steel is 3mm.

[0021] The production process includes billet assembly, heating, rolling, and water cooling, specifically:

[0022] (1) The steel billets designed and smelted according to the chemical composition are subjected to billet rolling; the thickness of the carbon steel Q345R billet is 247 and 142 mm respectively, and the thickness of the stainless steel intermediate billet is 16 mm. The surface cleaning of the composite surface is carried out by using a milling machine or an abrasive belt grinder. then follow figure 1 Combining the examples, adding a release agent between the stainless steels, and then welding and sealing the billet on four sides...

Embodiment 2

[0028] In this embodiment, A533B Class I is selected as the material of the base layer, and 304L is selected as the material of the multilayer. The finished product specifications of the composite board are: (62+7)+25 thickness×2040 width×12000 length mm, among which the thickness of A533B is 62 and 25mm respectively, and the thickness of stainless steel is 7mm.

[0029] The production process includes billet assembly, heating, rolling, and heat treatment, specifically:

Abstract

The invention discloses a production method of a rolled thick-specification composite steel plate, and belongs to the technical field of metal composite plate production. The composite steel plate is produced by surface treatment of a base plate and a composite plate, ply rolling, welding and vacuumizing of a matching board, wherein the vacuum degree is 10<-3> Pa to 10<-2> Pa; rolling and thermal treatment, wherein the rolling temperature is 1100-1200 DEG C, and the pressing rate for single time is 8-25%; separate cutting and flaw detection, detection, finishing and package. The production method has the advantages of realizing the production of the composite steel plate of which thickness is not less than 50 mm; the composite effect is good; the interface shearing intensity is 210 MPa or above; the performance of every layer can meet the standard requirement of corresponding materials.

Description

technical field [0001] The invention belongs to the technical field of metal composite plate production, and in particular relates to a production method for rolling thick-gauge composite steel plates. In particular, it relates to a production method for rolling a composite plate with a thickness greater than or equal to 50 mm. It is suitable for the production of thick-gauge stainless steel, nickel-based alloy and other clad steel plates for petroleum, chemical, nuclear power and other fields. Background technique [0002] As a new type of energy-saving and environmentally friendly functional materials, bimetallic clad steel plates such as stainless steel are widely used in petrochemical, water conservancy, salt production, nuclear power and other fields. At present, this kind of bimetallic composite panels is mainly produced by rolling method and explosion method in China. Among them, the explosion method is often used to produce thick specification composite panels in Ch...
