Steel strip water-cooled pressure plate quenching device capable of adjusting cooling final temperature

Abstract

The invention provides a steel strip water-cooled pressure plate quenching device capable of adjusting cooling final temperature. The device comprises an upper fixed plate, a lower fixed plate and an upright post for connecting the upper fixed plate and the lower fixed plate; the upper fixed plate is provided with an upper water tank, and an upper pressure plate is arranged at the bottom of the upper water tank; the lower fixed plate is provided with a lower water tank, and a lower pressure plate is arranged on the top of the lower water tank; a steel strip cooled and quenched by heat conduction of the upper fixed plate and the lower fixed plate passes through a space between the upper fixed plate and the lower fixed plate, and the upper water tank is provided with an upper water inlet and at least two upper water outlets formed in parallel in the horizontal direction; the lower water tank is provided with a lower water inlet and at least two lower water outlets formed in parallel in the horizontal direction; and valves are arranged on the upper water outlets and the lower water outlets. The device can be used for adjusting the cooling final temperature of the steel strip, is simple in structure, convenient to operate and low in quenching cost, and cannot pollute the environment.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a steel strip water-cooled press plate quenching device with adjustable cooling end temperature. Background technique [0002] Common steel strip quenching generally uses an oil-spraying pressure plate device. The disadvantage is that when the oil is sprayed on the hot steel strip, a large amount of oily smoke will be generated, making the whole workshop full of smoke, making the workshop full of oil stains, and it is easy to cause a fire. When the engine oil is brought into the tempering furnace, toxic carbon monoxide gas will be produced, which will damage the health of workers and seriously pollute the environment. Another shortcoming of this device is that its cooling end temperature cannot be adjusted, so it can only carry out martensitic quenching of steel strip. The invention patent with the patent number of 200810063322.5 provides a water-cooled platen quenching device for ...

AI Technical Summary

Problems solved by technology

At present, the steel strip quenching equipment that can control the cooling end temperature includes nitrate solution quenching equipment and lead bath quenching equipment, but the structure of these two equipments is relatively complicated, the cost of quenching is high, and it will pollute the environment
