Storage looper unit and band steel continuous hot-galvanizing machine unit

Abstract

The invention provides a storage looper unit and a band steel continuous hot-galvanizing machine unit, wherein the storage looper unit comprises a looping tower, a first position correcting device arranged at an inlet, a plurality of groups of storage loopers arranged in the looping tower, a second position correcting device arranged at an outlet and a third position correcting device arranged in the looping tower; furthermore, the looping tower comprises a front looping tower and a rear looping tower; the storage loopers are divided into a first storage looper and a second storage looper which are independently and mutually controlled and respectively arranged in the front looping tower and the rear looping tower; and the third position correcting device is arranged between the front looping tower and the rear looping tower. The invention reduces the running-off possibility of band steel in the looping tower, increases the length of the storage looping tower body, decreases the height of the storage looping tower body, realizes the increase of the structure rigidity of the device on the basis of not increasing materials and has the advantages of reasonable structure, rapid reaction, high controllability, high stability and the like.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of metallurgical equipment, and in particular relates to a material storage loop device and a strip continuous coating unit thereof. Background technique [0002] In recent years, the strip coating industry at home and abroad has developed rapidly, but most of them are low-capacity units. These units occupy a large area of ​​production capacity, low yield, and waste of resources. With the increase of units, the total production capacity will increase rapidly, and the market competition will become more intense. This will inevitably eliminate some units with poor conditions, poor management, high production costs, and low product quality. The market demand is also oriented towards high-capacity units. develop. High-capacity units are characterized by thick strips and fast plate speeds. For long-line units, these two characteristics require that the overall performance of the unit ne...

AI Technical Summary

Problems solved by technology

Since this type of storage looper adopts a single-tower structure, it lacks correction means for the strip steel 105 on the storage looper 103 in the looper tower 101, resulting in many units failing to meet the design requirements after being put into production. Can only reduce usage requirements

In addition, there are some designs that increase the height of the storage loop one-sidedly without taking reinforcement measures after the storage volume increases, resulting in serious mechanical vibration of the unit when the storage volume is full or high-speed operation, which increases the equipment life. dangerous
