Embodiment Construction

[0024] Such as figure 2 The shown continuous vertical quenching device for steel strips includes: a vertical quenching furnace 201; a vertical quenching oil tank 205 located below the vertical quenching furnace 201, which should maintain a sufficiently high quenching oil level 204 inside; The oil receiving tank 5 below the oil tank 205 has an outlet in the middle of the oil receiving tank 5, and the steel strip 1 after quenching enters the next process through the outlet. In addition, an annular rib is provided around the outlet to prevent the oil receiving tank from The quenching oil in 5 overflows from the outlet; the oil scraping base 206 that is arranged in the oil receiving groove 5 and is pressed on both sides of the steel strip 1, and the opposite side of the oil scraping base 206 is installed such as image 3 The wiper blade shown.

[0025] In this embodiment, a heating rod 202 is arranged in the vertical quenching furnace 201. The heating rod is a linear silicon-mol...

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...
