摘要： PURPOSE: To attain the long-time smooth operation of a vertical furnace by feeding a small amount of lumped chrome ore along the wall of the furnace so as to inhibit the reaction of vaporized SiO
2 or powdered CaO with the body of the furnace.
CONSTITUTION: Prereduced chrome ore is fed to a melting and reducing furnace 3 from blowing inlets 6 by means of hot air blown from tuyeres 15. The furnace 3 is provided with plural tuyeres for blowing hot air arranged vertically in two or more steps. A carbonaceous solid recuding agent 26 is charged into the furnace 3 through a feeder 13, and it is discharged from a bottom outlet 17 after reducing the chrome ore under melting. Lumped chrome ore 27 regulated to a smaller size than the size of the reducing agent 26 is fed along the wall of the furnace 3 from the top through charge pipes 18. By this method the reaction of SiO
2 vaporized from a flux or powdered CaO with the body of the furnace is inhibited, and the furnace is smoothly operated for a long period.

摘要： PURPOSE:To make the temp. of the top gas of a melt reducing furnace high and decrease the thermal load in the furnace wall part, to extend the life of the refractory material used for the furnace wall, by charging respectively separately the coarse grain raw material among preliminarily screened raw materials into the central part of the furnace and fine grain raw materials into the peripheral wall part of the furnace from the top of said furnace. CONSTITUTION:A preliminarily screened coarse grain raw material 5 is charged from the top of a melt reducing furnace 1 into the central part of the furnace 1 through a hopper 3, and a fine grain raw material 4 is charged through the hopper 2 to the peripheral part of the furnace 1. Powder oxide is blown from the lower part into the furnace 1 packed therein with a carboneous material such as mainly coke or the like to induce a reduction reaction and the resulting product of the reaction thereof is taken from the furnace bottom during this time. The resistance against the rise of the gas in the furnace in the central part of the furnace 1 is decreased by the above-described charging method for raw materials thereby decreasing the pressure drop, and central flow is formed in the gaseous flow in the furnace. On the other hand, the flow rate of the gas is decreased in the furnace wall part and thermal load is decreased. The furnace top gas is thus made high in temp. and the life of the refractory material used for the furnace wall is extended.
