Heat treatment production line for high-strength stainless steel plate

Abstract

The invention discloses a heat treatment production line for a high-strength stainless steel plate. Middle control using heat treatment operation terminal and feeding and discharging using grabbing manipulators cooperate with a sensing device on every apparatus, so full-line automatic running and unattended production are realized, the intelligent level is high, the heat treatment efficiency is high, the production capacity reaches 3800 tons / year, the heat treatment quality is high, and the flatness is not more than 2 mm / m<2>. The production line has the advantages of novel overall design, properness in material selection, perfect structure, high working stability, and realization of automatic heat treatment of 420J2 and other ultrathin high-strength stainless steel plates, effectively controls the quenching deformation to ensure that the flatness meets use requirements, fills in a domestic technical gap, reduces the use cost of related users, gets rid of the import dependence on Germany and Japan, has great industrial values, and is a production line suitable for steel plate heat treatment.

Description

technical field [0001] The invention relates to the field of a steel plate heat treatment production line, in particular to a stainless steel high-strength plate heat treatment production line. Background technique [0002] In the printing industry, the 420J2 high-strength stainless steel plate used for printing molds has long relied on imports, and the price is expensive, about 80,000 yuan per ton. This kind of steel plate cannot be produced in China. The main bottleneck is that the steel plate is too thin, only 1-2mm, but the strength is high, and the hardness after quenching is HRC52. If the deformation of the steel plate cannot be controlled during quenching, and the flatness cannot be guaranteed, the steel plate cannot be used after quenching . [0003] In order to reduce the user's use cost and get rid of the dependence on imports from Germany and Japan, we first designed and developed a high-strength stainless steel plate press quenching production line for quenching...
