A system and method for safe tapping

Abstract

The invention discloses a safe steel tapping system and method, and solves the problem that a steel billet cannot be discharged out of a furnace normally. The safe steel tapping system comprises a walking beam furnace, two distance measuring sensors and a control device, wherein the walking beam furnace is used for heating the steel billet and enabling the steel billet to walk to a discharging furnace door; the two distance measuring sensors are used for respectively transmitting distance measuring signals to the steel billet perpendicular to a furnace wall, respectively measuring distances from the steel billet to the two distance measuring sensors, and respectively sending the measured distances to the control device; the control device is used for receiving the distances measured by the two distance measuring sensors respectively, and determining whether steel is discharged or not according to the distances measured by the two distance measuring sensors respectively and the difference between the distances. The safe steel tapping system provided by the invention solves the problem of probability that the furnace wall is cracked up by the steel billet because the steel billet appears at an inappropriate position, improves the safety and achieves full-automatic steel tapping.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a safe tapping system and method. Background technique [0002] In the prior art, displacement sensors are generally used to measure the displacement of the walking beam cylinder, thereby obtaining the displacement of the walking beam, and thus the translational distance of the billet can be judged by the translational distance of the walking beam. This method only indirectly measures the stepping distance of the billet, but not the actual distance. In the actual movement of the steel billet, because the speed acceleration and deceleration process curves of equipment such as walking beams cannot reach the ideal state, and there are still some mechanical reasons, the walking beam may move relative to the steel billet during the process of moving, thus Make the steel billet deviation, can not be normally out of the furnace. [0003] In the existing heating furnace systems at home...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems in the prior art that due to the relative movement of equipment such as walking beams during the moving process of the billet, deviation errors occur or the billet cannot be released normally due to inaccurate stepping distances.
