Digital Ansteel China's first swirl well intelligent unmanned driving system put into use

Recently, the country's first swirl well intelligent unmanned driving system was put into use in the hot rolling line 1580 of Anshan Iron and Steel Co., Ltd. Bayuquan Branch. The problem of high work intensity has greatly improved the slag charging efficiency and effectively reduced the equipment failure rate. This is the first case in a domestic hot rolling mill.

The swirl well crane is located outdoors, and the mist emitted from the well contains harmful gases such as sulfur dioxide, which have adverse effects on the health of drivers. The slag flushing intensity of the swirl well is high, the turbulence in the well is serious, and the underground operation cannot be monitored. The workers can only rely on experience to manually grasp and discharge the slag, which not only has a high work intensity, but also cannot judge the height of the slag, which is easy to empty and affects the work. efficiency. In bad weather, nighttime and foggy conditions, the driver is in a blind grasping state, which will cause the grab bucket to collide with the slag flushing pool, damage the equipment and the steel rope from the groove, and the grab bucket to fall, which will lead to the untimely grabbing and discharging of the slag. The slag accumulation in the pump pool of the whirlpool well can even cause blockage in the well, resulting in a long-term production shutdown accident.

The hot rolling 1580 production line whirlpool intelligent unmanned driving system takes automation and artificial intelligence technology as the core, and is based on WMS logistics management system, driving PLC system and anti-sway system. Reduce manual operation and realize the integrated, intelligent and automatic control of the whole process. The intelligent unmanned driving system of the whirlpool effectively replaces the artificial vision and hand feeling for sinking and grasping the slag, efficiently and accurately lifts the grab bucket to the designated position, and discharges the slag at the preset position, realizing automatic sinking and grasping of steel slag and slag discharge, automatic position The control accuracy rate has reached more than 99%, and employees no longer have to brave the severe cold and heat to carry out heavy grasping and slag grasping operations outdoors. Independently innovatively designed the hook head set for swirl well driving with a perforated skirt cover, which effectively avoids the collision between the hook head and the grab bucket and the well wall, reduces the resistance of turbulent flow through the equipment, and reduces the equipment failure rate by more than 45%. Effectively improve the service life of the equipment. In addition, the design also adds a fixed grid-like silo device beside the well to avoid the impact of loading on the car body and the landing of steel slag, and improve the slag loading efficiency to more than 95%.
