Description

technical field [0001] The invention relates to the field of a walking heating furnace characterized by a path for processing discharged materials, in particular to a dynamic adjustment device for a slab discharging stop position of a walking heating furnace and a method for using the same. Background technique [0002] With the increasing demand for steel in modern industrial production, heating furnaces are playing an increasingly important role in modern hot rolling mills. Among continuous heating technologies, walking furnaces are the most widely used. When the walking heating furnace is working, the slab is transferred from the charging side to the discharging side through the stepping motion of the walking beam. The walking beam is composed of a movable beam and a fixed beam. Lift to the upper position, and then the movable beam is pushed forward by the translation cylinder to drive the slab to the discharge end of the heating furnace. A laser detector is installed n...

Problems solved by technology

Although this control method can ensure the stability of the walking beam and the reliability of the positioning of the slab, it has the following disadvantages: 1. When the leading edge of the slab reaches the laser detection point, the movable beam still needs to move forward until the current step is completed. It can only stop after the feeding cycle, which will slow down the tapping rhythm and affect the rolling rhythm of the rolling mill; 2. From the perspective of safety, the distance between the laser detection point and the discharging furnace door must satisfy the following relationship: D≥L+S, In the formula: D is the distance from the laser detection point to the discharge furnace door, L is the safety distance from the slab limit stop position to the discharge furnace door, and S is the step length of the walking beam

Obviously, due to waiting for the walking beam to complete a stepping cycle, the effective furnace length of the S distance is wasted, which reduces the heating efficiency of the heating furnace and increases energy consumption
