Unmanned system and operation method of steel ladle casting area

Abstract

The invention relates to an unmanned system and operation method of a steel ladle casting area. The method comprises the steps that a mechanical arm is prepared, wherein a robot grabs the mechanical arm from a mechanical arm standby station, the mechanical arm is placed into a fixed bayonet of a locating pile, and the mechanical arm is released; a long nozzle is prepared, wherein the robot takes out the long nozzle from a long nozzle storage device, the long nozzle approaches a mechanical arm long nozzle backing ring according to the set position, the position of the long nozzle is finely adjusted through a robot vision recognition system and a mechanical arm recognition mark, and then the long nozzle is placed into the long nozzle backing ring; a sealing part is mounted, wherein the sealing part is grabbed by the robot from a sealing part storage device and is placed into the long nozzle; and the long nozzle is mounted, wherein after a steel ladle rotates in place, the mechanical armis grabbed by the robot to drive the long nozzle and a lower nozzle to be aligned, the long nozzle is mounted in, the robot retreats, and the mechanical arm supports the long nozzle and presses the lower nozzle all the time. The unmanned system and operation method have the advantages that the mechanical arm and the robot cooperate to replace manual operation, and operations of long nozzle replacement, tundish molten steel temperature measuring and sampling, tundish covering agent adding and steel ladle oxygen pipe burning are completed.

Description

technical field [0001] The invention belongs to the field of ladle pouring, and in particular relates to an unmanned system for a ladle pouring area and an operation method thereof. Background technique [0002] The technological process of casting molten steel into slabs is: ladle → shroud → tundish → immersion nozzle → crystallizer → fan section; the ladle pouring area is located above the tundish, the main operations include replacing the shroud, tundish molten steel temperature measurement and sampling, Add medium pack covering agent. [0003] Among them, the replacement of the long nozzle is the most complicated. The first is to ensure safety, that is, the long nozzle is always pressed against the ladle’s lower nozzle to avoid steel spraying; the second is to ensure the quality, that is, the seal between the long nozzle and the lower nozzle to ensure that no air is sucked during the pouring process; Furthermore, to ensure efficiency, the replacement time is required to...
