Steel strip continuous vertical quenching device and quenching method

Abstract

The invention discloses a steel strip continuous vertical quenching device. The device comprises a vertical quenching furnace, a vertical quenching oil tank positioned below the vertical quenching furnace, an oil receiving tank positioned below the vertical quenching oil tank and provided with a leading-out port in the middle part, and oil scraping bases arranged in the oil receiving tank and pressed on two sides of a steel strip, wherein oil scrapers are mounted on opposite side surfaces of the oil scraping bases. The invention further discloses a quenching method using the steel strip continuous vertical quenching device. The steel strip continuous vertical quenching device can reduce the labor cost and improve the quenching efficiency; compared with horizontal online continuous quenching treatment, the steel strip cannot be deformed by self gravity influence; the level of quenching oil in the quenching oil tank is always kept on the same horizontal plane, so that the cooling speed of the cross section of the steel strip is consistent without forming internal stress to cause deformation of the steel strip; and the oil scraping bases achieve the effects of flattening, shaping, dirt removal and descaling on the steel strip.

Description

technical field [0001] The invention relates to a quenching device and a quenching method for a steel strip, in particular to a continuous vertical quenching device and a quenching method for a steel strip. Background technique [0002] At present, there are mainly two ways for steel strip quenching, one is discontinuous quenching, and the other is continuous horizontal quenching. Discontinuous quenching of the steel strip is to cut the steel strip into a specified length, put an appropriate amount into the furnace for quenching, oil cooling and other related processes. This method is cumbersome to operate, inefficient, and has high labor costs, so it is rarely used in the market at present. Continuous horizontal quenching such as figure 1 As shown, the steel strip 104 is quenched in the horizontal quenching furnace 101 and then cooled in the horizontal quenching furnace oil tank 103. There is quenching oil in the horizontal quenching furnace oil tank 103, and an oil recei...
