In a process for reducing and carburizing melting of metallic material in a rotary furnace having a melting zone extending along the entire length of the furnace there is supplied to the furnace above the melting zone a gas rich in oxygen and a liquid or gaseous hydrocarbon fuel in an amount sufficient to provide at least part of the heat required for the process, the oxygen being supplied in such a way that combustion of the fuel takes place in stages, the final stage in which the products are carbon dioxide and water taking place substantially out of contact with the bath and those products being removed from the furnace out of contact with the bath. The amount of oxygen supplied for the incomplete combustion of the fuel may be from 90% to 170% of that theoretically required for conversion of the fuel to carbon monoxide and hydrogen, while at least a part of the oxygen required to complete the combustion is supplied through the end of the furnace from which the exhaust gases are removed. A continuous layer of solid carbonaceous matter such as coke may be maintained on the bath. The process is particularly applicable to the melting of scrap-iron, sponge iron, or iron oxide materials, but can be applied also to nickel, iron-nickel, and iron manganese materials. Alloying additions and fluxes may also be charged to the furnace.

Title: Improvements in or relating to processes and apparatus for manufacturing a fire-polished glass strip
Inventor: GUSTAVE JAVAUX
IPC: B24D11/00
Filed: 1962-08-09
Abstract: <PICT:0981504/C1/1> <PICT:0981504/C1/2> <PICT:0981504/C1/3> In the production of fire-polished glass by sliding the formed strip continuously in contact with a molten material, inert at the temperatures of use, which decreases in temperature during the feed of the strip so that the strip can be removed without damage from conveyer members, the molten material is interposed in the form of a film between the strip of glass and a flat solid metal base so as to act as a lubricating agent to facilitate the forward feed of the glass strip.  As shown in Figs. 1 and 4, glass 2 flows from a furnace 3 over a lip 4 and over a flat solid metal member 5 forming the base of a tank 6 and spreads to abut carbon straight edges 7 parallel to the sides of the tank 6.  A molten substance 10, unaffected by air at working temperatures, is contained in the tank 6 and forms a film over the base 5, the base 5 being provided with grooves 17 to assist the maintenance of the film.  The base 5 is heated by resistances 14 in recesses in insulating blocks 15 below the base so that the temperature is controllably decreased from the pouring temperature to about 600 DEG  C. at which the surface of the glass is cool enough to be undamaged by the rollers 11, 12 removing the sheet 9 and passing it through the lehr 13.  Burners through apertures 16 maintain the temperature required above the glass sheet 9.  Preferably, so that an inert atmosphere is unnecessary, the carbon straight edges 7 are covered by the molten substance 10.  In place of the solid casting of the base 5, juxtaposed round rods on non-contiguous metal battens may be used. Scrapers 18 remove any molten substance 10 adhering to the strip 9, the scrapers being of glass fibre of higher melting point than the glass strip.  Alternatively, blowers may be used to blow heated air against the strip.  As shown in Fig. 5, glass strip 9 from a rolling mill 19 slides on an inclined cooled metal table 20 before dipping through a bath of the molten substance 10, which is lighter than the glass, to slide by gravity down the base 5 which is inclined, the strip then being drawn upwardly through the annealing lehr 13.  The tank 6 is mounted in a frame 23 pivoted at 24 and articulated at its opposite end to at least one jack 25 so that the inclination is adjustable.  The metal used for the base 5 is preferably Ag, An, Cu or an alloy thereof.  Materials for the substance 10 are salts, or mixtures of salts, of alkali metals or alkaline earths, preferably the chlorides.

Arms 55, Fig. 6, which project outwardly from a hub 54 on the shaft 51 and are backed by pliant strips 57, are provided with fingers 56 constituting mats which cooperate with a polishing material suspended in liquid in the tank or fed from pipes 66, 67 to polish the workpieces A ; the fingers and arms are of rubber or like material which may be reinforced with heavy fabric or the like. The workpieces A are mounted on holders 30 secured to pillars 31 disposed on members 26 arranged along the bottom of the tank to divert abrasive particles which settle out of the liquid towards the centre of the tank. A disc-like polishing head 52, which has downwardly projecting fingers 53, may be mounted on the shaft 51 for operating on the upper surfaces of the workpieces. Fitted to brackets 61 on posts 62 and disposed above the polishing heads is a cover 60 having its edges formed into flanges 63 which cooperate with flanges on the tank to prevent splashing of the liquid. In operation, the workpieces A are mounted on the holders 30 and the tank driven by the motor to carry the workpieces past the polishing heads. At the end of a stroke, a limit switch 74 reverses the drive and the tank reverses until a second switch 73 is operated ; the second switch provides a time dwell sufficiently long to permit removal and replacement of the workpieces on the holders 30. Ploughs 65 are secured to the cover 60 to agitate the sediment from the fluid during reciprocation of the tank. To maintain the liquid at 90 degrees F, cooling pipes 68 pass through the lower portion of the tank, or, if the liquid is circulated through pipes 66 and 67 by a pump P, a heat exchanger 69 may be employed ; the heated water may subsequently be used in a rinsing apparatus.
