Abstract: PURPOSE: A runner for preventing hot metal from flowing into blast furnace slag is formed by installing dam into the runner to reduce flow rate to result in extensive residence time of the hot metal within the runner. CONSTITUTION: A runner apparatus is operated by separating hot metal and slag in a runner having a skimmer (3), discharging such hot metal through an outlet and has a dam (7) hollowed on its lower part, which is attached near inflow area of the runner. The skimmer serves to separate the hot metal and the slag based on the difference of specific gravities therebetween. Also, a hollowed pore, at lower part of the dam, through which the molten iron can be passed. The dam is preferably installed at lower part of a slag zone (4). The slag zone is positioned at a point higher than upper part of a metal zone (6).

Abstract: PURPOSE: An illumination appliance is provided to achieve a torch light effect by coupling the illumination appliance with a fan so that the illumination appliance can be used in various fields. CONSTITUTION: An illumination appliance comprises a fan(20) driven by a motor(10). The fan(20) is electrically operated as the voltage is applied to the motor(10). An illumination lamp(44) is positioned by a predetermined distance apart from the fan(20). The illumination lamp(44) generates the light when the voltage is applied thereto. A torch light forming section(200) surrounds the illumination lamp(44). The torch light forming section(200) is fluttered when the wind is supplied thereto from the fan(20) so that the light generated from the illumination lamp(44) is viewed as a torch light.
