[0002] The converter is a crucial piece of equipment in steelmaking. Its lining operates under high temperatures and pressures for extended periods, constantly subjected to impacts and corrosion, making it prone to damage. Therefore, repairs are necessary. Current repair methods typically involve two assistants directing a dismantling machine to lift a large sheet of material from the furnace, quickly pushing it to the furnace opening and placing it inside. The furnace is then rocked back and forth to spread the material across the front surface, supplemented by some manual material dropping for repair.

[0003] However, the above-mentioned furnace repair methods have the following problems: they are complicated to operate, labor-intensive, prone to losing large amounts of fabric, and have poor furnace repair effects. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a furnace dismantling machine to attach a furnace repair tool to the machine and secure it to prevent rotation. After loading the hopper with repair material, the furnace dismantling machine lifts the hopper to the converter mouth. The hopper is then fixed at a specific position on the furnace mouth according to the repair location. The furnace dismantling machine's drill bit rotates the hopper 90-180°. A second assistant in the converter tilts the furnace to flatten or evenly spread the repair material in the hopper. Under high temperature and gravity, the repair material sinters and forms, achieving the purpose of furnace protection. This repair tool only requires placing the repair material into the hopper, placing the furnace dismantling machine on the furnace mouth, and flexibly adjusting the hopper's position to accurately deliver the repair material to the bottom or body of the furnace. The repair position changes with the tilting angle and can automatically and accurately reach the desired location, improving the accuracy of the repair. It allows for continuous delivery and is particularly effective in the later stages of converter operation, reducing the labor intensity of operators, improving on-site work efficiency and repair effect, and fundamentally solving problems such as difficult temperature measurement, complex operation, and reduced labor intensity.
