Overall lining removal (major overhaul)
Equipped with hydraulic breaker and chisel, it impacts and crushes aged and eroded refractory linings such as magnesia-carbon bricks and dolomite bricks on the converter inner wall, thoroughly stripping residual bricks from the furnace shell to prepare for new refractory masonry.
Slag cleaning for furnace mouth / hood / wall (daily maintenance)
Fitted with hydraulic grab shovel and slag raking head, it removes adhered slag, nodules and cold steel on the furnace mouth, hood and wall. It restores the standard furnace shape, ensures smooth gas flow and molten steel circulation, and prevents furnace deformation and uneven erosion caused by slag buildup.
Taphole repair / reaming / replacement
With dedicated taphole reaming drills and milling cutters, it drills out residual refractory bricks of old tapholes, performs reaming and shaping, and realizes rapid replacement of taphole sleeve bricks, ensuring smooth tapping and reducing slag carry-over.
Auxiliary furnace maintenance
Assists in handling and positioning new refractory bricks, and supports gunning and brick setting operations to greatly improve overall furnace repairing efficiency.
Safety
Adopts remote control and cab operation. Operators are kept away from high temperature of 700–1200℃, thermal radiation, heavy dust and falling bricks, eliminating high-risk manual working inside the furnace.
High Efficiency
Working efficiency is 5–8 times higher than manual dismantling. It greatly shortens converter shutdown maintenance time from several days to several hours, and improves steelmaking output.
Stable Quality
Precisely controls dismantling depth to avoid damage to the furnace shell, guarantee the masonry quality of new linings and extend furnace service life.
Cost Reduction
Cut labor input, reduce production loss caused by shutdown, and lower overall refractory material consumption cost.
