Vertical water-entry thick plate quenching machine

Abstract

The invention discloses a vertical water-entry thick plate quenching machine. The quenching machine comprises a quenching tank, wherein one side of the quenching tank is provided with a lifting device, and the other side, corresponding to the lifting device, of the quenching tank is provided with a swinging device, the lifting device comprises a plurality of lifting tracks arranged on one side wall of the quenching tank at intervals, and the lifting track is provided with a lifting trolley, the swinging device comprises beams hinged with the lifting trolleys, and the tank body edge at other side of the quenching tank is provided with a plurality of swinging cranks at intervals; one end of the swinging crank is fixedly connected with a rotating shaft, and the other end of the swinging crank is propped against the bottom of the beam, the swinging crank is driven by a driving device to swing around the rotating shaft; and spraying pipes are respectively arranged at interval parts corresponding to the beams and in the quenching tank. The quenching machine can enter the steel plate into the water in the vertical state, and is capable of effectively improving the quenching effect of the steel plate and improving the mechanical performance index of the product; the floor area of the quenching machine is reduced, and the equipment cost is lowered.

Description

technical field [0001] The invention relates to a metallurgical mechanical equipment, in particular to a vertical water-introduced thick plate quenching machine for heat treatment of extra thick steel plates. Background technique [0002] After entering the 21st century, especially in the past ten years, with the rapid development of my country's nuclear energy, military industry, shipbuilding industry, thermal power generation, bridge construction, oil and gas development and transportation, automobiles and construction machinery and other industries, various specifications, The demand for high-performance medium-thick plates and extra-thick plates is increasingly strong. In recent years, many domestic iron and steel enterprises have begun to invest in the construction of heat treatment production lines for medium and heavy plates and extra heavy plates. The quenching machine is the key equipment for quenching treatment. The heated steel plate is put into and out of water a...

Problems solved by technology

However, this type of technical solution has a complex structure, requires high equipment manufacturing and installation accuracy, is expensive, occupies a large area, and is difficult to overhaul and maintain. It can only achieve forced water spray cooling on one side of the steel plate, and the quenching effect on both sides of the steel plate is significantly different.
