Embodiment 1

[0050] The slag furnace melting and casting composite bimetal clad plate process includes the following steps:

[0051] Step 1: Buy or make self-made 304 stainless steel self-fluxing electrodes for cladding materials required for electroslag melting stainless steel composite panels, size: 255×20×2700, 2 pieces;

[0052] The second step: purchase the base material Q235 carbon steel plate of the size required for electroslag melting stainless steel clad plate, size: 330×230×680;

[0053] The third step: remove the oil stain and scale of the Q235 carbon steel slab, especially the surface of the metallurgical joint surface of the carbon steel plate is required to be bright and free of rust and inclusions;

[0054] Step 4: Assemble 304 stainless steel self-fluxing electrodes and dummy electrodes, and clamp two stainless steel billet mother electrodes to the two chucks of the same cross arm of the bipolar parallel electroslag furnace at the same time;

[0055]Step 5: Before loading...

Abstract

The invention relates to the technical field of bimetal composite plate preparation, in particular to a method for preparing a bimetal composite plate through electroslag casting. The method comprises the following steps: preparing a base steel self-fluxing electrode and a carbon steel plate as required; assembling an electroslag furnace electrode; assembling a crystallizer, and hoisting a carbon steel plate; smelting the base steel self-fluxing electrode; casting liquid-state base steel and a solid-state steel billet in the crystallizer to be compounded into an as-cast composite plate blank; rolling the composite plate blank into a composite plate through a hot rolling process; and sequentially carrying out heat treatment and surface treatment on the composite plate to obtain a finished plate. According to the method of the invention, stainless steel or nickel-based alloy and carbon steel are combined in a solid-liquid compounding mode, a source compounding technology is adopted, compounding is achieved through fusion and diffusion modes by means of sensible heat of molten metal, and the various problems that the bonding strength is poor, cost is high, efficiency is low, and large-scale production cannot be achieved in an existing compounding technology are solved.

Description

technical field [0001] The invention relates to the technical field of preparation of bimetallic composite panels, in particular to a method for preparing bimetallic composite panels by electroslag melting. Background technique [0002] Bimetal composite panel refers to a new type of composite material prepared by combining two metals with different properties, which combines the functionality of the clad material and the structural performance of the base material. [0003] Stainless steel / nickel-based alloy bimetal clad plate has both the corrosion resistance of stainless steel / nickel-based alloy and the high strength of carbon steel. It is a perfect substitute for expensive stainless steel / nickel-based alloy and can greatly save expensive stainless steel. / nickel-based alloy dosage, significantly reducing production costs. [0004] The current stainless steel / nickel-based alloy clad plate process is mainly divided into mechanical clad method and metallurgical clad metho...
