1497727 Control of agglomeration INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 18 March 1975 [27 March 1974] 11146/75 Heading C1A [Also in Division G3] An endless-grate agglomerating plant is controlled by measuring the temperature of gases passing through the charge and altering the velocity of the grate to keep the burnt-through point of the charge in a preset position, by generating a signal denoting the actual position of the burnt-through point relative to the grate, Lp, from, La, the location of the point of temperature rise of the gases and, V, the velocity of the grate, and k, a constant, such that The value Lp, may be compared with a reference input signal to generate a corrective signal, and the velocity of the grate may be altered accordingly. A value, Lt, denoting the theoretical position of the burnt-through point may be obtained from where F(p) is a transfer function, and compared with Lp to generate a deviation signal, altering the transfer function to cancel this deviation signal, and then comparing with the reference input signal as above. The apparatus for the invention is claimed. |
