Title: Improvements in or relating to a continuous process for making liquid steel from previously or "pre-reduced", solid starting products
IPC: C21C5/56
Filed: 1965-12-23
Abstract: <PICT:1095880/C6-C7/1> Pre-reduced solid material (e.g. sponge iron) containing heat-generating elements such as carbon, phosphorus and silicon is introduced into a bath of liquid steel into which oxygen is blown, while metal is continuously withdrawn from the bath to maintain the mass of the latter constant.  The pre-reduced material may be added in the form of pellets, or may be blown into the bath by a stream of hot reducing gases such as those evolved in the process. Additional materials of high calorific value, such as coke or graphite, ferro-phosphorus, ferro-silicon, aluminium or ferro-aluminium may also be charged to the bath; these may be mixed with the iron bearing material or may be injected in a blast of air. Further heat may be supplied by combustion of all or part of the evolved gases above the bath by means of a stream of secondary oxygen.  The process may be carried out in apparatus of the type illustrated, wherein pelleted ore from hopper 1 is fed into vessel 2 in which an emulsion of metal and slag is formed by a jet of oxygen from lance 5.  Thus emulsion overflows into receiver 6 where the metal and slag separate out and are discharged.  The gases evolved in vessel 2 are partially burnt by oxygen from lance 10 and are then discharged through stack 9.

A valve for controlling the flow through an opening 2 in the bottom of a container 1 has a closure member in the form of a float 4 secured to a tube 16 which is guided at 6, 7 for axial movement. Variation in the height of the liquid in the tank actuates the valve.

Staple textile fibres, e.g. wool fibres are stretched and set by inserting twist into a sliver of the fibres, passing the twisted sliver through the nips of two pairs of rollers spaced apart by a distance greater than the staple length of the fibres being treated, the second pair of rollers being driven at a greater speed than the first pair, and setting the fibres in the extended condition. The twist imparted corresponds to a twist multiplier within the range of 600-1000. The sliver 8 passes through a twisting device 9 and into a stretching and setting apparatus through guide eye 14 adjacent one end of roller 1. Each pair of rollers has an idler roller 6, 7 and the sliver passes in a helical path around both sets of rollers 1, 6 and 2, 7 to enter and leave the apparatus at the same end (see Fig. 3). The helical path is determined by guide pins 11. Chamber 21 constitutes a steaming zone containing steam jets 13 and chamber 23 constitutes a drying zone.

In a gas cooled turbo-generator the coolant gas is passed through radial channels between the stator laminations into the air gap and by the effect of rotation is drawn through cooling channels in the rotor winding slots formed between the bundle of conductors in the slots and the insulated slot wall. In the form shown, the bundle of conductors 8, consisting of individual insulated conductors glued together, is spaced from slot wall insulation 7 by a spacer 9 which is provided by an insulating tape helically wound on the bundle with a pitch several times greater than the width of the tape. Coolant is drawn in through slots 12 and travels around the conductor bundle through the space 24 to outlet 13 on the opposite side of the conductor bundle. In a modification axially spaced distance pieces are bent around the bottom of the bundle and on one side extend to the top of the conductor as a rectangular piece and on the other side of the bundle as a triangular piece, Figs. 7 and 8 (not shown). In this construction the coolant again flows from an inlet on one side of the bundle to an outlet on the other side. In a further modification the spacers comprise axially spaced tongues glued to the top and sides of the conductor bundle and having a length less than the depth of the slot. Coolant flows around the tongues but is restricted to flow on one side of the bundle only, Figs. 10-13 (not shown). If the tongues consist of superposed layers of material the ends may be secured between the conductors in the bundle.
