A method of placing a quantity of refractory sand in the discharge channel of a bottom discharging metallurgical vessel includes the steps of orienting the vessel whereby the channel is presented in a horizontal direction, and opening the channel. A generally cylindrical cartridge of refractory sand, closed at both ends, is then loaded onto a casing dimensioned to slide into the discharge channel. The casing with its cartridge of sand is then slid into the channel, the channel is closed and the vessel is righted.
