摘要： An arrangement for preheating scrap includes a scrap treating furnace into which at least one exhaust gas duct from a metallurgical furnace enters. In order to attain a higher efficiency in preheating, the scrap treating furnace has a through chamber for a plurality of adjacently arranged or superposed scrap receiving vessels. Each of these vessels is provided with its own gas inlet opening and with its own gas exit opening. The scrap treating furnace also includes a charging means on one end of the through chamber to receive at least one scrap receiving vessel and a discharging means on the other end of the through chamber to receive at least one scrap receiving vessel. A conveying means for moving the scrap receiving vessels in cycles from the charging means to the discharging means as well as gas conducting means for connecting the gas exit openings with the gas inlet openings of neighboring scrap receiving vessels are arranged within the through chamber.

摘要： The exhaust-gas treatment system of a sealed-type steel converter is operated at the time of an emergency during blowing by a method which comprises stopping the blowing of oxygen, opening an emergency air suction device connected to the hood while, at the same time, maintaining a converter controlling damper at its degree of opening at the time of stopping of the blowing, disconnecting the skirt of the hood from the converter mouth, and opening the damper to a specific degree of opening. By this simple method, sudden and great pressure drops within the converter are prevented, whereby CO gas of high purity can be efficiently recovered without the occurrence of damage to parts of the system due to abrupt pressure difference and explosion of CO gas.

摘要： A hood assembly for use with a metallurgical converter is disclosed. The hood assembly comprises a hood resting on a supporting structure and having sidewalls the lower ends of which extend downwardly to a short distance from the apron plate of the converter and around a portion of the periphery of the converter corresponding to the angular movement of the mouth of the converter from the blowing to the charging position, and the upper ends of which follow a curve-linear or straight path extending from the upper back end of the hood until it meets with the lower ends of the sidewalls at the front of the hood, and a roof bridging the sidewalls except for an opening at the front of the hood extending over the mouth of the converter in the charging position. A gate extends over the opening in the roof of the hood and a pair of lifting arms are located on each side of the hood for pivoting the gate in a convex curved path from a closed position over the opening in the roof to an open position over the roof of the hood.

摘要： A method is described for suppressing fume generated in the transfer of molten metal to a receiver. The involved method entails burning fuel in the immediate vicinity of the molten bath within the receiver to consume and/or displace ambient air thereby to starve the bath of oxygen and, concomitantly, to suppress the formation of the fume-producing metallic oxide.

摘要： Pneumatic seals are provided at the seams about movable doors of the containment enclosure for a metal processing converter to prevent leakage of undesirable effluent to the atmosphere. The seals incorporate members on the doors and the adjacent enclosure structure which, when the doors are closed, define labyrinth passages for conducting clean air from an elevated pressure source to discharge simultaneously into the enclosure interior and to the atmosphere. The invention contemplates, as an alternative, connection of the passages to a low pressure source effective to withdraw the effluent leakage for discharge into a receiver.
