Granted: 1994-02-14
Abstract: The pig iron is made by reducing the iron ore of wide particle size distribution in a preliminary reduction furnace and in a smelting reduction furnace. The prereduced iron ore of below 1 mm particle size is charged in the smelting reduction furnace by exhaust gas of the preliminary reduction furnace. The prereduced iron ore of 1-5 mm particle size is gravitated into the smelting reduction furnace. The prereduced iron ore of above 5 mm particle size is gravitated into the smelting reduction furnace after being pre-reduced and heated again. The method raises the preliminary reduction rate.

According to the invention, the device comprises a cylindrical body comprising several segments (1, 2, 3) closed at its end by a cap (4), a shaft (5) resting, at one end, on the wall of a support and driven thereby, while, at the other end, it is supported on a bushing (6) on which there rests a tip (7) mounted within an axial orifice (a) cut into the shaft body (5) and which is supported by a flanged bushing (8) which rests on another compensation bushing (9), on the shaft (5) there being also mounted some worms (10, 11, 12) which are axially separated by some tapered profiled bushings (13) so that the lower diameter thereof coincides with the bottom diameter of the previous worm, while the upper diameter thereof coincides with the diameter of other tapered separation bushings (14), on each said segment (1, 2, 3) there being provided an external jacket (15, 16, 17) closing one chamber, wherethrough the cooling water circulates continuously.

Title: Metal cans with peelable lids
Inventor: IAN MAXWELL
Filed: 2012-11-04
Abstract: A method of sealing a peelable lid to a flange provided within a metal can body which involves inserting an induction coil into the can body to primarily heat the sealing surface of the flange, whilst keeping the exterior wall of the can relatively cool to avoid tin reflow and decoration degradation of the exterior wall. The induction coil is subsequently removed from the can body and a peelable lid applied to the flange, whereby residual heat in the flange aids the sealing of the lid to the flange, e.g. by allowing activation of a bonding material.
