Roller spray quenching equipment

Abstract

The invention relates to roller spray quenching equipment. A motor in the transmission system refers to a frequency-conversion adjustable-speed motor; the motor is connected with a driving tug by virtue of a reducer with a certain speed ratio so as to provide corresponding linear velocity for the roller; a water supply system comprises a water collection tank for collecting wastewater; the water collection tank is connected with a filtering water tank; the filtering water tank is connected with a circulating water pool; the circulating water pool provides cooling water for a pressure stabilization tank by virtue of a water pump; the pressure stabilization tank provides injection water for a water nozzle by virtue of a water distributor; a safety shield is arranged on the upper part of the rack in a supporting system; and a high-temperature roller positioned in a rotating state is enclosed in the safety shield. The linear velocity of the roller body is changed by virtue of the frequency-conversion adjustable-speed motor, so that a good spray quenching effect is achieved; all the pipelines of the water supply system pass through the same pressure stabilization tank, the water pressure of each water nozzle is constant, the water nozzles are basically positioned in the same water pressure state, the uniformity of axial hardness of the roller body is guaranteed, and the water resources can be well saved by virtue of the water circulation system; and moreover, the equipment safety can be improved by virtue of the safety shield.

Description

technical field [0001] The invention relates to roll heat treatment auxiliary equipment, in particular to roll spray quenching equipment with high safety, good use effect and simple installation and operation. Background technique [0002] The roll is a high-wear part. During the steel rolling process, the hardness of the roll body is very high. Therefore, in the roll production process, the heat treatment of the roll is a very important link. The roll spray quenching machine is a kind of equipment designed to improve the hardness of the roll body during the heat treatment process of the roll. Most of the existing roll spray quenching machines use ordinary motors. During the spray quenching process, the linear speed of the roll body cannot be adjusted, and the water is not recycled, which wastes a lot of water resources. Moreover, the rolls in the high-temperature rotating state are exposed to the working environment, which has great risks. Security risks. Roll spray quenc...
