Abstract

The invention discloses a metallurgically bonded stainless steel clad bimetallic steel and its preparation process, which includes a carbon steel core and a stainless steel cladding. The composite molding process includes the overall heating of the outer stainless steel tube to 600-1000°C by using an induction heater. The inner layer of carbon steel is poured into molten metal and cast to produce a clad bimetallic composite billet with a metallurgically bonded interface; the melted and cast bimetallic billet is hot-rolled to form a clad bimetallic section steel. The metallurgical bonding interface between the stainless steel layer and the carbon steel core is formed by melting and casting, and has the advantages of high bonding strength, excellent process performance, compact structure, good quality, fewer procedures, low cost, and high efficiency. The present invention uses bimetallic steel instead of integral stainless steel. On the premise of ensuring the anti-corrosion properties of steel, it not only saves stainless steel materials, reduces engineering costs, but also effectively improves the strength of steel bars, reduces waste of resources and energy and environmental pollution, and has the advantages of Broad application prospects.

Description

Technical field [0001] The invention relates to the technical fields of metal composite materials and metallurgical steel rolling, and in particular to a metallurgical bonded stainless steel-coated bimetal steel bar and its preparation process. Background technique [0002] Section steel is a strip of steel with a certain cross-sectional shape and size. It is one of the four major varieties of steel (plate, tube, profile, and wire). According to the cross-section shape, section steel is divided into simple section section steel and complex section section steel (special-shaped steel). Simple section steel refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; complex section steel refers to I-beam, channel steel, rail, window frame steel, curved steel, etc. Section steel is generally used for machining, structural connection, etc. At present, angle steel, channel steel, I-beam, H-shaped steel, etc. are widely used in industry and construction....
