Embodiment 1

[0019] figure 1 It is a schematic diagram of a water-piercing cooler for three-slit rolling after flange connection is adopted; the three water-piercing pipes 4 are respectively connected to the water-cooling seat 1 of the water-piercing cooler and the return water seat 5 of the water-piercing cooler.

[0020] Such as figure 2 As shown, when the water-piercing pipe 4 is connected to the water-cooling seat 1 of the water-piercing cooler, there are four bolt holes on the flange 2 (or eight, set according to the actual situation), and the bolt holes match the number of bolts 3 .

[0021] Such as image 3 As shown, when the water-piercing pipe 4 is connected with the return seat 5 of the water-piercing cooler, there are four bolt holes on the flange 2 (or eight, set according to the actual situation); the number of the bolt holes and the bolt 3 match.

[0022] This embodiment 1 is a water-through cooler for three-slit rolling after adopting flange connection. , the vertical ...

Abstract

The invention discloses a method for prolonging the service life of a through-water cooler for bar rolling. A through-water pipe is connected with a water cooling seat of the through-water cooler through a flange bolt assembly, and the through-water pipe is connected with a water return seat of the through-water cooler through a flange bolt assembly. By adopting the method, the problem that a Venturi pipe in the through water cooler cannot be maintained due to single radial wear is solved.

Description

technical field [0001] The invention belongs to the technical field of steel rolling heat treatment equipment, and relates to a method for improving the service life of a water-through cooler for bar rolling. Background technique [0002] The bar production line mainly produces hot-rolled construction steel and ordinary carbon steel. In the production process, it is necessary to rely on the water-piercing equipment after rolling to heat-treat the product to ensure its high metal mechanical properties and good surface quality. The original water-piercing equipment is a closed circular tube water-piercing cooler, which is mainly composed of a water-cooling seat, a water-piercing pipe and a water-returning seat. Water-cooling guides are fixedly installed in the water-cooling seat and the water-returning seat. Tube. The original water-through cooler water-cooling seat, water-through pipe and water return seat adopt a non-detachable connection method. After the cooler has been ...
