Disclosed is a thermal reduction apparatus. The thermal reduction apparatus according to the exemplary embodiment includes: a preheating unit which preheats a to-be-reduced material and loads the to-be-reduced material into a reducing unit; the reducing unit which is connected to the preheating unit and in which a thermal reduction reaction of the to-be-reduced material occurs; a cooling unit which is connected to the reducing unit and from which the to-be-reduced material flowing into the cooling unit is unloaded to the outside; a gate device which is installed between the preheating unit and the reducing unit; a gate device which is installed between the reducing unit and the cooling unit; a condensing device which is connected to the reducing unit and condenses a metal vapor; a first blocking unit which is installed in the reducing unit; and a second blocking unit which is installed in the reducing unit so as to be spaced apart from the first blocking unit.

Thermal reduction apparatus for metal production, gate device, condensing system, and control method thereof

A continuous casting machine and method using molten mold flux, wherein the continuous casting machine includes a mold cover for covering an upper portion of a mold; a mold flux melting unit for melting mold flux to be supplied into the mold; and a mold flux delivery unit for supplying the mold with the molten mold flux melted in the mold flux melting unit, wherein the delivery unit includes an injection tube with one end connected to the mold flux melting unit and the other end positioned in the mold through the mold cover, and an injection tube heater for heating the injection tube. Since a slag bear continuous casting machine and method using molten mold flux is removed, the consumption of mold flux is greatly increased compared with the case of a conventional casting work, so that the friction between a mold and a solidified shell is reduced. As a result, an amount of scarfing of a cast piece is greatly reduced and no carbon pick-up occurs.
