Description
Technical field
The present invention relates to the preparation of composite, especially apply in composite metal plate field, the milling method of a kind of Multi-layer metal alloy clad steel plate.
Background technology
At present, resource provision contradiction is the most prominent, and nickel valency height enterprise causes domestic Stainless Steel to produce cost of raw material surge, production cost and use cost and strengthens, and China's nickel resources is the deficientest, most dependence on import, and this is accomplished by finding out a production technology saving the energy.Double metallic composite material had both possessed the performance such as corrosion-resistant, wear-resisting of the metals such as stainless steel, aluminium, copper, titanium, can save again precious metal, reduced cost, and aspect energy-conservation for China has outstanding role.
Stainless steel material is the metal material that a kind of performance is the most excellent, it is widely used in electronics, space flight, aviation, chemical industry, automobile, the industrial circles such as machinery, stainless steel materials is the product form that it is important, account for the 40～60% of total output, but due in recent years, chromium, the shortage of the resources such as nickel, stainless supply will be had a strong impact on, therefore, for solving the deficiency caused by shortage of raw materials, realize the strategy of sustainable development of metal material, and use the method for accumulative roll bending to produce layer composite material, greatly reduce current stainless steel material to chromium, the raw-material demand such as nickel, alleviate imbalance between supply and demand.Meanwhile, layer composite material thickness proportion is uniform, and structure property is excellent, also can adjust proportioning as requested, meet all trades and professions demand to material property.
China relies on explosive type composite for a long time, this technological danger, production cycle limitation are the biggest, blow and can not produce, snow and can not produce, less than 8 specifications can not produce, 60～100 can not produce, and the produced stress of blast can not be completely eliminated, repeatedly stress generation explosion accident on the project application such as oil, petrochemical industry.
Summary of the invention
The purpose of the present invention, it is exactly for solving the problem that prior art exists, and devise the milling method of a kind of Multi-layer metal alloy clad steel plate, the ingredient stability when steel plate making production dispatches from the factory, surfacing is without local stress, and this method can produce continuously, do not affected by weather and specification, can be mass produced in batches.
The technical scheme is that the milling method of a kind of Multi-layer metal alloy clad steel plate, its concrete milling step includes:
Step one, polishes to each metal level, clean dirt；
Step 2, stacks metallic plate neatly according to above-mentioned order；
The gap welding of step 3, stainless steel layer and carbon steel layer, uses secondary welding mode, welds and carries out sealing welding according to interior external ordering, utilizes vavuum pump to vacuumize process.
Step 4, is heated up to the multilayer steel plates that superposition is good 800 degree and keeps 3 hours；
Step 5, puts into upper step light plate and rolls 5 ~ 8 passages (determining rolling pass according to finished product thickness) in clad steel plate rolling mill；
Step 6, the sheet material that rolling is completed carries out surrounding cutting and peels off, then carries out steel plate heat treatment, uses cold leveling technology that steel plate is fixed to every square meter unevenness less than 2mm.
Described multiple layer metal includes upper and lower two-layer carbon steel sheet, is provided with two-layer corrosion resistant plate between carbon steel sheet.
It is provided with scaling powder between described carbon steel sheet and corrosion resistant plate,；It is coated with antitack agent between described two-layer stainless steel.
Described stainless steel layer be coating thickness be 0.5 ~ 10mm, carbon steel layer be groundwork thickness be 2 ~ 100mm.
Described scaling powder is Ni-based anticorrosion alloy.
In described step 3, welding manner is for using submerged arc or manual arc welding method.
Described leveling uses level(l)ing machine special equipment to carry out cold leveling.
In described step one, scale removal process is: first with milling drum, carbon steel and stainless steel watch surface oxidized skin are removed, until exposing fresh metal, then carries out clearing up dust, impurity with clean cold wind.
Beneficial effects of the present invention can be drawn by such scheme: owing to multiple layer metal forms steel billet to be rolled, scaling powder is placed in the middle of two kinds of metals, specific billet rolling temperature control makes scaling powder melt and flows between steel, form moistened surface, powerful depressing force at milling train, controlled rolling through multi-pass, make the effective flow of carbon steel and nickel-base alloy surface and metallurgical binding, bond strength is high, product quality is improved without local stress, large-scale production, improve lumber recovery, production range is extended to 2mm ~ 100mm, production and development to enterprise create huge space.
As can be seen here, the present invention compared with prior art has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent from.
