Method for continuously producing non-corrodible steel and non-corrodible steel composite reel

Abstract

A method for continuously producing a stainless steel and stainless steel composite coil, which belongs to the field of stainless steel composite board technology. The method comprises the following steps: continuously sandwiching a solder layer between two kinds of stainless steel, coiling coils of two different materials by a tension of 3 to 30 tons, applying a special high-temperature anti-bonding agent on a roller with non-composite surface, transferring the reeled pre-combined coil to a power induction furnace, heating to 950 to 1,130 DEG C, keeping the temperature, quenching, and tanking out to obtain desired stainless steel composite coil with a combination rate above 99.5% and a shear strength larger than 300 MPa. The method has the advantages that two kinds of stainless steel coils with different trademarks and different thickness can be combined together to obtain a composite stainless steel coil with high corrosion resistance on one side and high mechanical strength and high heat transfer coefficient on the other side.

Description

technical field [0001] The invention belongs to the technical field of stainless steel clad plates, and in particular provides a method for continuously producing stainless steel and stainless steel clad coils, which is suitable for manufacturing various stainless steel and stainless steel clad coils, especially for the production of two different grades of stainless steel for compounding. Methods. Background technique [0002] There are four main manufacturing methods of existing metal clad plates: explosive cladding, explosive hot-rolling cladding, hot-rolling cladding, and semi-continuous periodic production of metal clad coils. [0003] The above-mentioned explosive cladding, explosive hot-rolling cladding, and hot-rolling cladding methods cannot continuously produce coils, and the process is extremely complicated and the production cost is high. The method of semi-continuous periodic production of metal composite strip coils can produce double-sided or single-sided low...
