Rolled steel segmented cooling device

Abstract

The invention discloses a rolled steel segmented cooling device. The rolled steel segmented cooling device comprises a conveying mechanism, a water penetrating mechanism at least partially arranged onthe upper portion of the conveying mechanism, and a cooling water providing mechanism communicating with the water penetrating mechanism; the conveying mechanism comprises a table body (1), a conveying belt (2) is arranged at least on the upper surface of the table body, and a plurality of conveying areas are formed on the conveying belt in sequence in the conveying direction; the water penetrating mechanism comprises a plurality of water penetrating pipes (8) arranged on the upper portion of the conveying mechanism, wherein a plurality of through holes (9) are formed in each water penetrating pipe; and the through holes of the water penetrating pipes face the conveying belt, sliding rails (10) are arranged on the side face of the table body in the conveying direction of the conveying belt, and each water penetrating pipe is slidably arranged on the sliding rails through a sliding rod (11). The cooling condition of the rolled steel segmented cooling device can be adjusted on one cooling line, and the cooling effect is effectively improved.

Description

technical field [0001] The invention relates to the field of steel rolling equipment, in particular to a steel rolling subsection cooling device. Background technique [0002] Steel rolling, referred to as steel rolling, is a pressure processing process that changes the shape of steel ingots and billets between rotating rolls. Its purpose is to obtain the required shape, such as: steel plate, strip steel, wire rod and various profiles, etc., and at the same time, to improve the internal quality of the steel during its rolling process. [0003] Steel rolling is often divided into cold rolling and hot rolling, and the cooling step is necessarily involved in the cold rolling process. After traditional bar rolling, rapid cooling is often used to realize the waste heat treatment process, that is, the steel bar with a final rolling temperature of 900-1100 °C is cooled by a water cooler and directly quenched on the surface, so that the surface temperature is quickly dropped to 200...

Problems solved by technology

After traditional bar rolling, rapid cooling is often used to realize the waste heat treatment process, that is, the steel bar with a final rolling temperature of 900-1100 °C is cooled by a water cooler and directly quenched on the surface, so that the surface temperature is quickly dropped to 200-300 °C for cooling. The cooling is often carried out under the condition of one-step cooling, which often causes the surface of the bar to be chilled, resulting in poor material properties and other problems.
