Title: Method of constructing refractory linings for metallurgical furnaces
IPC: F27B3/12

Abstract: 1,042,468. Furnace linings. SOC. FRANCAISE DE PRODUITS HYPO-METALLURGIQUES, SOC. LA MAGNESIENNE, SOC. DES PRODUITS INDUSTRIELS ET MAGNESIENS DU ROUSILLON, and R. C. M. F. BLONDEL. July 16,1963 [July 19, 1962], No. 28187/63. Addition to 864,118. Heading F4B. In a method of constructing a refractory lining for a metallurgical furnace as claimed in the parent Specification, the refractory material forming the lining wall is compacted between a a cylindrical envelope 1 and a cylindrical former 3 by at least one sonic or ultra-sonic vibratory tool 5 whose working surface 6a, as illustrated in Fig. 3 (not shown), is shaped as a sector of the annular space between the envelope and the former. In the embodiment shown, a lining for an electric induction furnace is formed by spreading dry unbonded refractory material within an asbestos envelope 1 having an induction coil therearound and tamping the material down using the vibratory tool or tools to form a base. A metal former is then positioned concentrically within the envelope and an annular lining wall built up by compacting successive loose refractory layers with one or more tools 5 which can move in a circular path above the annular space between the envelope and former. Curved refractory bricks 7 complete the lining. Various suitable refractory lining materials are specified.

Abstract: 1,188,256. Automatic furnace temperature control systems. OWENS-CORNING FIBERGLAS CORP. June 13, 1968, No.28217/68. Heading G3R. In a furnace temperature control system wherein one or more burners are fired intermittently, a bias signal is developed inverse in sign and substantially equal in magnitude to a predicted or sensed deviation in temperature from its level before interruption and which signal thereafter decays to zero, which is added to the normal temperature measuring signal to control the amount of fuel supplied to the burner(s). A thermocouple T1 controls a fuel supply valve 31 through a controller 33, the fuel supply being interrupted periodically by a timer 70. To limit the flow of fuel on restarting a fixed signal from a generator 80, which may be developed in a RC circuit, or derived from a motor driven rheostat is added to the signal from thermocouple T1 so that the valve 31 is not moved substantially from the position attained before interruption of firing. The signal from generator 80 gradually decays and that from thermocouple T1 gradually assumes control. In an alternative arrangement a signal from another thermocouple T2 is employed to vary the amplitude of the bias signal, or in a further arrangement a separate signal from thermocouple T1 may be employed. Additionally a relay 40-42 may be employed to disconnect the valve motor 32 during the transition period. The furnace may have a plurality of burners e.g. 11, 12 which are fired intermittently and sequentially through valves 51, 61 by the timer 70, which timer may be replaced by a controller responsive to temperatures in furnace regenerators of differences in temperatures between various regenerators. Preferably the bias signal decays to zero in an exponential manner.
