This utility model discloses a low-density, carburizing-resistant clay brick for dry quenching furnaces, belonging to the technical field of clay bricks. It includes a body with several arc-shaped grooves evenly spaced on its lower end surface and several stepped protrusions matching the arc-shaped grooves evenly spaced on its upper end surface. The body has several closed holes inside, and symmetrical grooves for placing Y-shaped anchors are provided on its left and right side walls. The bottom of the vertical part of the Y-shaped anchor is integrally formed with a limiting base. This utility model of a low-density, carburizing-resistant clay brick for dry quenching furnaces makes construction quality more controllable and reliable, ultimately ensuring the long service life of the dry quenching furnace lining.

This invention discloses a robotic system and construction method for hot repair of bottom bricks in the confined space of a coke oven carbonization chamber. The system includes a tracked walking mechanism, a material conveying platform, a base, a robot, a brick replacement mechanism, and an imaging mechanism. The tracked walking mechanism moves along the bottom of the carbonization chamber. The material conveying platform transports bricks to the material collection point. The base provides stable support for the robot. The robot is equipped with a cooling unit to ensure it operates at high temperatures. The brick replacement device includes a T-shaped support, the top of which connects to the end of the robot. A mortar application mechanism is located at the front end, and a cleaning mechanism is located at the rear end. The cleaning mechanism includes a brick milling component, a brick joint milling component, a brick clamping component, and a ash removal component. During repair work, the imaging mechanism performs a detailed scan of the bottom bricks in the coke oven carbonization chamber. The robot moves the brick replacement mechanism to the damaged area, cleans, applies mortar, installs a brick, and completes the repair work. This system can accurately complete the hot repair of the bottom bricks in the carbonization chamber.
