Problems solved by technology

Among them, the first four methods are only suitable for small batch production of special products, with low efficiency and high technical level requirements; the disadvantages of the explosive composite method are that the bonding strength is relatively low, there are waves on the bonding surface, and the deep processing performance is not good
These shortcomings severely limit the output and application range of bimetallic / multimetal composite panels

Embodiment 1

[0019] The method of the invention can produce composite steel plates with a thickness of 3 mm to 50 mm and a width of 1000 mm to 4000 mm, and composite steel strips with a thickness of 1 mm to 10 mm and a width of 230 mm to 4000 mm depending on the capacity of the rolling mill.

[0020] Manufacture 3.0mm×1000mm×10000mm, three-layer stainless steel composite plate for cutting tools with a finished substrate thickness of 0.3mm. The substrate blank is AISI440A stainless steel of 3.5mm×1000mm×2500mm, and the double plate blank is AISI304 stainless steel of 20mm×1010mm×2520mm. First use a special metal cleaner to clean the surface of the base and double board, rinse with water and dry, then soak in hydrochloric acid with a concentration of 21-30% for a period of time, rinse and dry, and then put it on a sandblasting machine for sandblasting. In order to activate the surface atoms while cleaning the surface, it is beneficial to the combination during rolling. As shown in Figure 1,...

Embodiment 2

[0022] Manufacture 3.0mm×1100mm×10000mm, three-layer stainless steel composite plate for cutting tools with a finished substrate thickness of 0.5mm. The substrate blank is 9Cr18Mo steel of 5.0mm×1100mm×2500mm, and the double plate blank is 1Cr13 stainless steel of 13.0mm×1110mm×2520mm. First use a special metal cleaner to clean the surface of the base and double board, rinse with water and dry, then soak in dilute sulfuric acid with a concentration of 17-20% for a period of time, rinse and dry, and then put it on the sandblasting machine for sandblasting , so as to activate the surface atoms while cleaning the surface, which is beneficial to the combination during rolling. As shown in Figure 1, the surfaces to be compounded of the substrate blank 1 and the doubler blank 2 are superimposed, and the contact edges of the base and doubler blanks are spot-welded every 50mm for initial fixation, and then the base and doubler panels are bonded with a 2000t press. Squeeze out the air...

Abstract

The invention is a method for manufacturing a metal composite plate for the use of a cutting tool, which belongs to the technology field of manufacturing the metal composite plate. The invention comprises following procedures: the surface of base plate blank and flyer plate blank that is to be recombined is cleaned and activated; the primary fixation of dot welding is adopted and the method of compressor air exhausting is adopted for assembling; hot rolling; thermal treatment and acid washing and edge cutting. The invention can make use of an existing plate and a slab band mill and adopt direct hot rolling to manufacture the metal composite plate with good quality. The mechanical property, the corrosion resistance and the bond quality of the composite plate satisfy or even precede national standards. Compared with the prior art, the invention has the advantages of simple technology, high output and good bond quality.

Description

technical field [0001] The invention relates to the manufacturing technology of metal composite boards, in particular to a method for producing bimetal / multi-metal composite boards for cutting tools by direct hot rolling. technical background [0002] In addition to good comprehensive mechanical properties, metal composite panels are more economical and resource-saving. For example, for the same type of products, the price of stainless steel composite panels is only 60% to 70% of the price of stainless steel, so using stainless steel composite panels as raw materials can greatly reduce production costs and increase product added value. In addition, my country's resources are increasingly scarce, such as nickel metal used to produce stainless steel, the price continues to rise due to the reduction in reserves, so the development of metal composite panels has great economic and social benefits. [0003] At present, the production methods of bimetal / multi-metal composite panel...
