PURPOSE:To enable the easy and rapid exchange of the titled supply pipe by supporting the pipe in a freely rotatable state, making the pipe dividable at a position close to the base end, and enabling easy attachment and detachment. CONSTITUTION:A long-sized castable refractory supply pipe 1 supported by a frame can be divided into a long-sized front supply pipe 1d and a short-sized rear supply pipe 1e at a position close to the base end. The pipes 1d, 1e can be easily attached and detached by cutting engaging grooves 1h in the pipe 1d and fixing engaging rods 1i which are slid into the grooves 1h on the pipe 1e. When the pipe 1 is clogged with castable refractory or damaged, the pipe 1d can be detached rapidly and easily from the pipe 1e and can be exchanged. |
