Roller way steel billet information tracking method of walking beam furnace

Abstract

The invention relates to a roller way steel billet information tracking method of a walking beam furnace. The method comprises the following steps that a pair of laser cold and hot metal detectors is installed at the corresponding position of a roller way; a corresponding steel billet information queue is set for each roller way in the PLC system; and the steel billet information is moved into or out of the corresponding steel billet information queues by combining signals of the laser cold and hot metal detectors at the corresponding positions with forward and reverse rotation signals of the corresponding roller ways, so that steel billet information tracking under normal or abnormal production working conditions is realized. By the adoption of the method, full automation of the billet information tracking process can be achieved, labor cost is saved, product number errors caused by manual statistics errors are reduced, and therefore normal operation of enterprises is prevented from being affected.

Description

technical field [0001] The invention relates to the field of walking heating furnaces in the metallurgical industry, in particular to a method for tracking billet information of a roller table of a walking heating furnace. Background technique [0002] The metallurgical industry walking heating furnace is a gas-fired industrial furnace used in the rolling process to keep the hot slab sent by continuous casting or the cold slab in the billet warehouse warm or heated to the rolling temperature of the subsequent rolling mill. The rising, advancing, falling and retreating actions of the water-cooled metal beam at the bottom move the billet forward step by step, so it is called a walking heating furnace. Its advantages are: flexible material transportation, and all the furnace materials can be discharged out of the furnace when necessary; the billets are placed at intervals on the furnace bottom or beams, which can be heated evenly and quickly; the arch steel of other types of he...

AI Technical Summary

Problems solved by technology

[0004] 1. The detection instrument for billet tracking outside the heating furnace is easily blocked by external disturbances (personnel, pollutants, etc.), or the signal failure caused by the failure of the equipment itself, the deployment of the detection instrument must be redundant deployment

[0005] 2. In the process of tracking billet information, problems such as loss of billet information and timing errors cannot occur

[0006] 3. When tracking in the heating furnace, the signal of the walking beam moving forward or backward, as well as the stepping distance may not be accurate, and the position of the billet cannot be completely relied on the position of the billet accumulated according to the stepping distance
