Problems solved by technology

However, there are obvious defects in the explosive composite method: 1. It is not suitable for producing thin composite panels with a thickness of less than 10mm; 2. Because it uses the energy of explosives to produce, it will cause vibration, noise and smoke pollution to the environment; and other process conditions, the production efficiency is low
However, the hot-rolled clad plate method also has obvious defects: 1. Large investment and high cost; 2. Due to the limitation of the compression ratio of rolled steel, hot-rolled production cannot produce clad plates with a thickness of more than 50 mm or less than 5 mm.
[0007] However, in the actual production and processing process, if only the base plate and the cladding plate are naturally stacked together during blank assembly, since the materials of the base plate and the cladding plate are different, the subsequent In the welding process, it is difficult to realize the hermetic welding of the substrate and the cladding plate

Embodiment 1

[0037] see figure 1 , a base plate is made of carbon steel plate, and a cladding plate is made of 304 stainless steel plate. The specific processing steps are as follows:

[0038] S1. Surface treatment: Surface treatment is carried out on the surface to be bonded of the substrate and the surface to be bonded of the superstrate, that is, one side of the substrate and one side of the superstrate respectively, and the surface to be bonded of the substrate and the surface to be bonded of the superstrate are cleaned sticky sand and scale.

[0039]Specifically, the substrate is sent into the shot blasting machine, and the shot blasting device of the shot blasting machine throws projectiles (steel balls) at high speed, impacts one side of the substrate respectively, and removes the sticky sand and scale on the surface until the surface is clean and free of Rust spots; send the cladding plate into the shot blasting machine, and the shot blaster of the shot blasting machine throws pro...

Abstract

The invention discloses a processing method of a carbon steel and 304 stainless steel single-sided composite board. The processing method of the carbon steel and 304 stainless steel single-sided composite board comprises the following steps of (1) conducting surface treatment; (2) assembling; (3) processing grooves; (4) applying pressure in a segmented mode, welding the grooves, and then welding and sealing all the grooves; (5) vacuumizing; (6) heating; (7) conducting hot rolling; (8) conducting cold rolling; and (9) carrying out post-treatment to obtain the composite sheet. According to the processing method of the carbon steel and 304 stainless steel single-sided composite board provided by the invention, an adhesive is adopted for bonding in the assembling process, so that primary connection is achieved; the grooves are processed in the welding process, and the pressure is applied in the segmented mode, welding and secondary welding are conducted on the grooves, so that local upheaval or upwarping of a combined blank plate is avoided, and firm metallurgical bonding can be formed between a base plate and a covering plate; and the carbon steel and stainless steel single-sided composite sheet processed by each processing step has corrosion resistance and good mechanical strength and processability.

Description

technical field [0001] The invention relates to the technical field of production of stainless steel clad plates, in particular to a processing method for carbon steel and 304 stainless steel single-sided clad plates. Background technique [0002] The stainless steel clad plate is a clad steel plate made of a carbon steel substrate and a stainless steel cladding plate or different series of stainless steel substrates and cladding plates. Its main feature is that carbon steel and stainless steel form a strong metallurgical bond, which can be processed by hot pressing, cold bending, cutting, welding, etc., and has good process performance. [0003] At present, there are three main methods for industrial production of stainless steel clad plate industry, namely explosive clad method, hot rolling clad method and cold rolled clad method. [0004] The explosive composite method is to place the cladding plate on the base plate overlappingly, and a certain distance is set between t...
