Device for hot-rolled strip steel production line to achieve uncoiling of steel coils in small batches

Abstract

The invention belongs to the field of steel industry and discloses a device for a hot-rolled strip steel production line to achieve uncoiling of steel coils in small batches. The device for the hot-rolled strip steel production line to achieve uncoiling of the steel coils in small batches is capable of effectively utilizing equipment for checking strip steel and capable of supplying individual scattered steel coils. A pinch roll rolling device is correspondingly mounted behind a strip steel checking line after final output of hot-rolled strip steel, and the pinch roll rolling device is structurally characterized in that upper rolls and lower rolls are mounted on a frame, the distance between each upper roll and the corresponding lower roll is equal to the thickness of the strip steel, an adjusting mechanism for adjusting the distance between each upper roll and the corresponding lower roll is arranged on the frame, the upper rolls are connected with upper universal drive shafts, the lower rolls are connected with lower universal drive shafts, the upper universal drive shafts and the lower universal drive shafts are connected with a shaft of a motor through a gear box, and a band-type brake is mounted on the shaft of the motor. The device is simple in structure, reasonable in design and capable of performing simple equipment upgrading and optimizing layout of process equipment in an existing workshop without adding lifting equipment, and accordingly product yield can be effectively increased, equipment usage rate is increased, and product manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the field of steelmaking industry. Background technique [0002] The finished products produced by the hot-rolled strip steel production line need to be headed off. The cut off head is basically discarded as waste, and the finished product needs to be cut strip steel samples and strip steel quality inspection to ensure product quality. This process This is done on the coil inspection line near the end of the line. The inspection of the steel coil is to cut the steel coil into a section of strip steel, and the workers in charge of the inspection will identify it with the naked eye. After confirming that it is correct, it will be put into the warehouse for use. Big waste. On the other hand, some enterprises that use strip steel do not need the whole coil of strip steel at all. Because there is no corresponding equipment, the production enterprises basically do not supply this kind of retail customers, which makes the company vi...

Problems solved by technology

The inspection of the steel coil is to cut the steel coil into a section of strip steel, and the workers in charge of the inspection will identify it with the naked eye. After confirming that it is correct, it will be put into the warehouse for use. big waste

On the other hand, some enterprises that use strip steel do not need the whole coil of strip steel at all. Because there is no corresponding equipment, the production enterprises basically do not supply this kind of retail customers, which makes the company virtually lose a group of individual customers. more or less certain loss

The domestic hot rolling production line only cuts strip steel samples and conducts strip surface inspection to reduce the product yield, and the utilization rate of inspection line equipment is very low. Generally, the utilization rate of inspection line equipment is about 10%
