Abstract

The invention provides a cast rolling H-shaped steel section cooling device. The cast rolling H-shaped steel section cooling device comprises a shell, three sets of upper spraying nozzles, an upper spraying pipe, three sets of lower spraying nozzles, a lower spraying pipe, three sets of left spraying nozzles, a left spraying pipe, three sets of right spraying nozzles and a right spraying pipe. The shell is of a box-shaped structure, the three sets of upper spraying nozzles are arranged in the shell and are used for being respectively aligned with two R portions of the upper side of the H-shaped steel section and the center of a web perpendicularly, the upper spraying pipe is arranged in the shell and is connected with the three sets of the upper spraying nozzle, the lower spraying pipe is arranged in the shell and is connected with the three sets of the lower spraying nozzles, the three sets of the left spraying nozzles are arranged in the shell and are sequentially arranged from top to bottom and are used for being aligned to the left side face of the H steel section to enable cooling water to be evenly sprayed to the left side face of the H steel section, the left spraying pipe is arranged in the shell and is connected with the three sets of left spraying nozzles, and the right spraying pipe is arranged in the shell and is connected with the three sets of right spraying nozzles. Cooling water sprayed by each set of spraying nozzles does not interfere with each other. The cast rolling H steel section cooling device enables the H steel section to be good in organization state, and therefore better comprehensive mechanical property is obtained.

Description

technical field [0001] The invention belongs to the technical field of controlled cooling of H-shaped steel production, and in particular relates to a casting-rolled H-shaped steel cooling device for controlling and cooling the rolled H-shaped steel on a cast-rolled H-shaped steel production line. Background technique [0002] As an ideal economic section steel, H-beam has the advantages of large section modulus, economical and reasonable section, strong bending resistance, light unit weight, good performance, beautiful appearance, convenient use and saving metal materials compared with ordinary I-beam. It has been widely used in beam-column structural components in industrial and civil building steel structures, steel structure load-bearing supports of industrial structures, industrial equipment frames such as petrochemical and electric power, long-span steel bridge components, mechanical Manufacturing and transportation vehicles, ship frame structures and engineering struc...
