Abstract

The invention relates to a laminar flow collecting pipe cooling water quantity control device. The control device mainly solves the technical problems that the cooling water amount of existing hot-rolled laminar flow cooling equipment is difficult to regulate and control, and the equipment manufacturing and operation cost is high. The laminar flow collecting pipe cooling water quantity control device comprises a plurality of spraying pipe devices, each spraying pipe device comprises a collecting pipe, a plurality of uniformly distributed spraying pipes, a front water outlet pipe and a rear water outlet pipe are arranged on each collecting pipe, and for each collecting pipe, the front water outlet pipe and the rear water outlet pipe are fixedly arranged on the two sides of the middle of thecollecting pipe correspondingly; and each spraying pipe device further comprises mounting discs, flow driving discs, width driving discs, flow rocking handles, width rocking handles, fixing pins, inner copper sliding bearings, outer copper sliding bearings, pull rings, a hole-free arc-shaped plate, a porous arc-shaped plate and a water sliding groove, wherein the mounting discs are fixedly arranged at the two ends of the collecting pipe, the mounting discs are provided with the inner copper sliding bearings, and two circles of fixing through holes are formed in the surface of each mounting disc. The laminar flow collecting pipe cooling water quantity control device is simple in structure and low in manufacturing and operation cost.

Description

technical field [0001] The invention relates to laminar flow cooling equipment for hot rolling in the field of iron and steel metallurgy, in particular to a laminar flow header cooling water control device, in particular to a laminar flow header for a hot output roller table or a laminar flow roller table of a hot rolling production line Cooling water quantity control device. Background technique [0002] Hot rolling production is a production method for pressure processing of metals at a high temperature of 850-1250°C. However, in the stage of hot output roller table, the amount of cooling water is related to the speed of strip temperature drop and has a great influence on the strength of strip steel. strong relationship. The water demand of the hot run-out roller table is mainly related to the thickness of the strip and the width of the strip. [0003] At present, the header of the heat output roller table generally adopts two methods for spraying water, the laminar flow...
