Abstract

The invention belongs to the technical field of quenching devices, and specifically relates to a liquid bismuth alloy quenching device. The device comprises an uncoiling wheel, a coiling wheel and a steel strip, wherein a heating furnace and a quenching furnace for thermally processing the steel strip are arranged between the uncoiling wheel and the coiling wheel; the heating furnace and the quenching furnace are subjected to height difference and are completely closed; the quenching furnace is inverted trapezoidal and comprises a first quenching box and a second quenching box which are separated through a separating plate; the first quenching box comprises liquid bismuth stored in the first quenching box, and a heating plate which is arranged at the outer side of the first quenching box and is used for adjusting the temperature of the liquid bismuth; and a hollow upper pressing plate for supporting the cooling of the steel strip and a lower pressing plate for supporting the steel strip are correspondingly arranged at two sides of the steel strip in the first quenching box. According to the device, water cooling and spraying cooling are integrated to quench the steel strip; the device is environmentally friendly, simple, high in production efficiency, high in surface smoothness and high in flatness. The invention also discloses a quenching technology of the liquid bismuth alloyquenching device.

Description

technical field [0001] The invention relates to a liquid bismuth alloy quenching device and a quenching process. It belongs to the technical field of quenching devices. Background technique [0002] Quenching is a heat treatment process in which the workpiece is heated to austenitize and cooled in an appropriate manner to obtain martensite or bainite structure. The most common ones are water-cooled quenching, oil-cooled quenching, air-cooled quenching, etc. The heat treatment process of quenching and tempering usually adopts continuous quenching and tempering equipment for steel strips, which is composed of three parts: quenching heating furnace, quenching cooler and tempering heating furnace. The steel strip in the heat-resistant steel pipe is heated to 860-920°C by a quenching furnace, and its structure changes from ferrite + pearlite structure to austenite structure, and then a high-hardness marsh is obtained under the forced cooling of the quenching cooler. The temper...
