Abstract

The invention belongs to the technical field of metal plate-strip heat treatment devices, and provides a plate-strip roller type quenching device and a plate-strip roller type quenching method capableof realizing reverse quenching. The device is formed by a front high-pressure cooling area, a rear high-pressure cooling area and a middle low-pressure cooling area; when a plate-strip enters from the front high-pressure cooling area, a forward quenching method is implemented; and when the plate-strip enters from the rear high-pressure cooling area, a reverse quenching method is implemented. According to the device and the method, the utilization rate of the quenching device can be greatly improved; and a special cooling device and a special cooling strategy are adopted for the thin and thickplates-strips, so that the heat treatment plate shapes and the uniformity of the plates-strips are improved at the same time, and multiple purposes are realized through one machine.

Description

technical field [0001] The invention belongs to the technical field of heat treatment equipment for metal plates and strips, and relates to a roll-type quenching device and method for plates and strips that can realize reverse quenching. Background technique [0002] The roller quenching machine has strong cooling capacity, uniform cooling, high production efficiency, good shape of the plate and strip after cooling, equipment length is not limited by the length of the plate and strip, and can realize continuous production. It can be used for carbon steel, stainless steel, special alloy, Titanium alloy, aluminum alloy and other metal plates and strips are produced by quenching, solid solution, and controlled cooling. The thickness range of plate and strip production is 2-300mm, the width range is 1-5m, and the length range is 3-30m. It is the main form of cooling equipment for large-scale heat treatment lines. . For the cooling of plates and strips with a thickness of 2 to 8...
