Problems solved by technology

In addition, using the vacuum rolling method to produce composite panels has better advantages than the existing traditional technology. The traditional billet assembly process mainly uses the method of sealing and welding around, then drilling and then vacuuming, because this method requires sealing and welding. After drilling and vacuuming, the process is more cumbersome, and it is mainly completed by manual operation, which has a certain impact on the rolling success rate.

Embodiment 1

[0035] A TMCP type marine austenitic stainless steel clad plate and its preparation method provided in this embodiment, the blank structure is as follows figure 1 As shown, the details are as follows:

[0036] The DH32 steel type with a base material thickness of 102mm is selected, and the chemical composition is shown in Table 1. The composite material blank is selected from S31603 austenitic stainless steel with a thickness of 18mm, and the rolled finished product is S31603+DH32 composite plate with a thickness of 3+17mm.

[0037]One of the surfaces of the two DH32 base material blanks and the two S31603 composite material blanks was ground, so that the fresh metal was completely exposed on the surface. Apply silicone release agent or alumina / magnesia type release agent to the unpolished surface of the composite material, and dry the release agent at 550°C to 650°C. Spot-weld and fix the seals around the polished surface of one of the base materials. The seals are made of c...

Embodiment 2

[0041] A TMCP type marine austenitic stainless steel clad plate and its preparation method provided in this embodiment are as follows:

[0042] The DH36 steel type with a base material thickness of 60mm is selected, and the chemical composition is shown in Table 1. The composite material blank is S30403 austenitic stainless steel with a thickness of 12.5mm, and the rolled finished product is a S30403+DH36 composite plate with a thickness of 2.5+12mm.

[0043] One of the surfaces of two DH36 base material blanks and two S30403 composite material blanks was ground to expose the fresh metal completely. Apply silicone release agent or alumina / magnesia type release agent to the unpolished surface of the composite material, and dry the release agent at 550°C to 650°C. Spot-weld and fix the seals around the polished surface of one of the base materials. The seals are made of carbon steel; the non-composite surfaces of the two composite materials are superimposed and placed in the gro...

Embodiment 3

[0046] A TMCP type marine austenitic stainless steel clad plate and its preparation method provided in this embodiment are as follows:

[0047] The AH32 steel grade with a base material thickness of 82.5mm is selected. The chemical composition is shown in Table 1. The composite material blank is selected from S31703 austenitic stainless steel with a thickness of 16.5mm, and the rolled finished product is S31703+AH32 composite plate with a thickness of 3.0+15mm.

[0048] One of the surfaces of the two AH32 base material blanks and the two S30403 composite material blanks was ground so that the fresh metal was completely exposed on the surface. Apply silicone release agent or alumina / magnesia type release agent to the unpolished surface of the composite material, and dry the release agent at 550°C to 650°C. Spot-weld and fix the seals around the polished surface of one of the base materials. The seals are made of carbon steel; the non-composite surfaces of the two composite mate...

Abstract

The invention discloses a TMCP type marine austenitic stainless steel composite plate and a preparation method thereof and relates to the technical field of bimetal composite manufacture. The preparation method comprises blank preparation, surface grinding, isolating agent brush-coating, assembly blank sealing, electron beam soldering and sealing, heating, rolling and cooling, straightening, and cutting separation. The TMCP type marine austenitic stainless steel composite plate effectively solves the problem of corrosion resistance of the composite austenitic stainless steel in the composite plate, and in the blank preparation process, the steps of drilling and vacuuming are avoided. The preparation method has simple processes and a high rolling yield.

Description

technical field [0001] The invention relates to the technical field of bimetal composite manufacturing, in particular to a TMCP type marine austenitic stainless steel clad plate and a preparation method thereof. Background technique [0002] In recent years, the number of chemical tankers built in China has gradually increased. One of the key technologies for building chemical tanker tanks is the selection of tank lining materials. Good chemical corrosion resistance is an important condition for material selection. Therefore, most of its liquid cargo tanks and liquid cargo pipes are made of stainless steel. In order to ensure corrosion resistance, weldability and economy, the stainless steel commonly used is 316L (00Cr17Ni14Mo2), 304L (0Cr18Ni9) and 2205 duplex stainless steel (22Cr23Ni5Mo3N). Among them, duplex stainless steel has better corrosion resistance and structural strength, but its price is still high at present, which has become a major bottleneck restricting the ...
