2. the preparation of composite billet: substrate compound plate being snapped together, then will be carried out along the surrounding of substrate and compound plate close
Soldering and sealing connects, and then vacuumizes to slab；
3. composite billet surrounding applies side: after the impurity such as surrounded surface scale removal of composite plate blanks, under protective atmosphere, pouring
The fusing molten steel of casting and the same material of compound plate；
4. prepared by pack rolling composite billet: the stainless steel double level of the composite billet on two deposited sides being stacked relatively, between the two layers
Brushing interleaving agent is fully welded, two sides spot welding using adjacent stainless steel layer head of the stainless steel electrode to composite billet；
5. heating and rolling: pack rolling composite billet being put into heating furnace and is added according to the production heating cycle of plied timber
Thermal control；Pack rolling composite billet after heating is rolled, start rolling temperature, finishing temperature and the roller repairing technique of rolling according to
The production technology of plied timber is rolled.
The manufacturing method of above-mentioned stainless steel clad plate carries out customized assembly acording to the requirement of user, needed for being rolled into
In the case where multiple tube, the usage amount of edge stainless steel is reduced to the greatest extent.
The manufacturing method of above-mentioned stainless steel clad plate, the interleaving agent are that the mixing of aluminium oxide, magnesia and powder of lacquer putty for use on is molten
Liquid is brushed with a thickness of 0.5-1mm.
The manufacturing method of above-mentioned stainless steel clad plate, the heating furnace heating temperature are 1200-1250 DEG C, start rolling temperature
At 1000-1150 DEG C, previous three passes reduction ratio is not less than 13%, and total compression ratio is not less than 2.5, and finishing temperature is in 930-1000
℃.0.5~2m/s of mill speed.
The manufacturing method of above-mentioned stainless steel clad plate can carry out the assembly of multiple deposited side composite plates according to product demand,
Production is customized, production efficiency is improved, is the top view of 4 pieces of deposited side composite panel bases as shown in Figure 5, after the completion of rolling,
Stainless steel clad plate needed for being cut into 4 pieces.
Stainless steel clad plate after the rolling, acording to the requirement of user to carry out heat treatment and other processing.
Advantage of the present invention and good effect:
It is compared with the traditional method compared with advantages of the present invention:
The present invention overcomes the difficulty of current composite metal plate pipeline welding, the problems of inefficiency.It is rolled from composite plate
Assembly processed is started with, customizing to produce, and edge is the composite metal plate of stainless steel material of the same race.Thus composite plate (pipe) is welded
The welding of the place's of connecing composite plate is converted to the welding of stainless steel metal of the same race, thus simplify the complexity of composite plate (pipe) welding,
Improve production efficiency.
