Problems solved by technology

However, due to the contradiction between the constant-speed water supply pump and the variability of water consumption, the motor of the constant-speed water supply pump is often suffocated, and it is also easy to cause damage to the water-through cooling equipment

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0019] The present invention provides a water-through cooling and stabilizing device for small bars, which includes a water supply pump 2 and a water-through cooling device 8, the water supply pump 2 and the water-through cooling device 8 are connected through a water supply pipe, and the water supply pipe is provided with Sustaining pressure relief valve 7.

[0020] The water supply pump 2 is a constant speed water supply pump 2, and the constant speed water supply pump 2 is generally arranged in the water pump room 1. In this embodiment, a plurality of water supply pumps 2 are arranged in the water pump room 1, and the plurality of water supply pumps 2 pass through The longer wa...

Abstract

The invention discloses a small bar material through-water cooling stable device which comprises a water supply pump and a through-water cooling device. The water supply pump and the through-water cooling device are connected with each other through a water supply pipe. A pressure holding and releasing valve is arranged on the water supply pipe. According to the small bar material through-water cooling stable device, the pressure holding and releasing valve is further arranged on the main water supply pipe, thus, when the water supply amount of the water supply pump is not matched with water demanding amount, redundant water can be drained through the pressure holding and releasing valve, so that the stability of a through-water cooling system and the economy of the water supply pump are ensured, the constant pressure of the water supply pipe is ensured, and the water pump and equipment are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of steel cooling, in particular to a water-penetrating cooling and stabilizing device suitable for small bars. Background technique [0002] In the production line of hot-rolled small bars, in order to improve the performance level of steel bars, the mechanical properties of steel bars are currently improved by cooling the finished steel bars after rolling. [0003] The water pressure requirements for water-through cooling of small bars are relatively high, generally between 1.8Mpa-2.5 Mpa, and the water consumption of steel bar through-water cooling, according to different steel types and specifications, is generally 100m 3 / h-500m 3 / h between. [0004] At present, in order to save investment, many steel mills generally use constant-speed water supply pumps for the water-through cooling devices in the cooling system, which are three-purpose and one-backup or two-purpose and one-backup. However, due to the contrad...
