Abstract: A process for the production of pig iron from iron ore is disclosed. The pig iron is firstly converted to sponge iron in a direct reduction shaft furnace (1) and then the sponge iron is converted to pig iron in a melt-down gasifier (2). The shaft furnace and melt-down gasifier are interconnected by means of downcomers (6). Apart from the sponge iron, the melt-down gasifier is supplied with a carbon carrier in the form of coke and oxygen-containing gas. The gas produced in the melt-down gasifier is supplied to the shaft furnace (1) in the form of reduction gas via downcomers (6), pipe (8), cyclone separator (12) and pipe (4). By means of pipes (10 and 11), cooled, cleaned blast furnace gas from shaft furnace (1) is admixed as cooling gas with the gas produced in the melt-down gasifier. With the aid of a screen (15), the melt-down gasifier is supplied with the fine fraction via pipe (7) and the shaft furnace is supplied via pipe (16) with the coarse fraction of the coke required for the operation of the plant.

Abstract: In a cutting machine, a cutting arm is swivellable around a horizontal axis and around a vertical axis and carries on its free end a cutting tool. The horizontal swivelling axis of the cutting arm is displaceable relative to the frame of the cutting machine. Displacing of the horizontal swivelling axis is allowed by arranging the swivelling axis on a rocker arm connected with the frame of the cutting machine and is turnable around a vertical axis and is swivellable around a horizontal swivelling axis. With the rocker arm assuming a lowered position, the horizontal swivelling axis of the rocker arm is, as seen in an advancing direction, located in front of the horizontal swivelling axis of the cutting arm. The swivelling drive, for example is formed of a hydraulic piston-cylinder-arrangement, for swivelling the cutting arm around its horizontal swivelling axis and is supported on the rocker arm.
