Zinc boiler nose online position adjusting device

Abstract

The invention discloses a zinc boiler nose online position adjusting device. The device comprises a boiler nose body provided with a measuring reference surface at the lower end, a first detector anda second detector respectively arranged on the left side and the right side of the boiler nose body for detecting a first distance from the first detector to the left end of the measuring reference surface and a second distance from the second detector to the right end of the measuring reference surface, a first extension adjusting device and a second extension adjusting device respectively connected with the left side and the right side of the boiler nose body, a frame, and a controller for judging the levelness of the boiler nose body according to a difference value between the first distance and the second distance and controlling the first extension adjusting device and / or the second extension adjusting device to drive the left side and / or the right side of the boiler nose body to movealong the frame according to the judging result. Through reasonable structural design, the zinc boiler nose online position adjusting device dynamically monitors the levelness of the boiler nose, andcan automatically adjust the levelness of the boiler nose.

Description

technical field [0001] The invention relates to an adjustment device, in particular to an adjustment device for a zinc boiler nose. Background technique [0002] As the key equipment of the galvanizing line, the zinc boiler nose plays an extremely important role in the quality of the product. The GI production line is equipped with a cleaning device at the head of the furnace nose, its function is mainly to generate overflow through the level difference of the internal zinc liquid, and the zinc liquid and zinc slag in the overflow tank are pumped out by the zinc liquid pump to ensure the cleanliness and improve strip quality. Therefore, the requirements for the levelness of the furnace nose head and the height of the overflow port are relatively high, so as to ensure that the height of the overflow notch in the cleaning device is consistent along the direction of the strip steel, and the zinc liquid can maintain a normal overflow state. [0003] At present, the domestic me...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic measurement of the levelness of the nose of zinc boilers is still carried out manually through a level gauge. Therefore, every time the head of the furnace nose is replaced, the levelness must be measured, which is time-consuming and laborious. And because there is no dynamic monitoring, during production If there is a level error caused by the thermal expansion of the metal, it cannot be found in time

In addition, when the level of both sides of the cleaning device of the furnace nose deviates, it can only be adjusted through the pull rod above the furnace nose. After adjustment, repeated measurements are required, which is very cumbersome
