Title: Automatic control of pig iron refining
IPC: C21C5/46
Filed: 1967-04-12
Abstract: 1,141,430. Programmed process control. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. April 12 1967 [April 20, 1966], No. 16197/67. Heading G3N. [Also in Division C7] To control an oxygen steelmaking process the variation with time of the intensity of sound in the converted and the variation with time of the temperature of the exhaust gases, or of another variable related to the heat content of those gases, are recorded, and the operating conditions such as rate of oxygen flow, lance height, supply of lime, or characteristics of the oxygen jet adjusted so that the two curves obtained follow predetermined paths. By this means it is possible to obtain a desired iron content in the slag during the final stage of refining. In a preferred embodiment of the process, the relationships between the various parameters are first determined experimentally, and adjustment of the operating conditions is then carried out automatically so that the abovementioned two curves follow predetermined lines on the graphs. A suitable arrangement is illustrated schematically.

In a modification, a burner (26), Fig. 13 (not shown), has water, liquid oxygen, or a mixture of these, injected into the stream of oil and gaseous atomizing medium prior to ignition through a conduit (109). A combustion chamber 121, Fig. 14, may be placed over burner 23 replacing water tube 40, Fig. 10, and the chamber has a Venturi-like effect, in that air is drawn into the upstream end of the chamber at 122 to assist in the combustion process. The chamber is connected to the burner by brackets 127, and can be adjusted upstream or downstream. A water ring 123 having adjustable nozzles 125 is provided.
