Title: Control of iron mineral sintering by temperature - measurement
IPC: C22B1/20
Filed: 1969-04-17
Abstract: Iron minerals ares intered with coke by passing the mixture continuously at a controlled speed from a supply hopper and the speed varied to stabilise the position of the sintering band of the optimum temp. Control is effected by placing three thermo-couples in the correct positions laterally in the aspiration-boxes to determine the temperatures at the centre of the meass along the band. A cruve is plotted of thesetemperatures, and thus the temperature of the most crucial part, the centre, is plotted, and controlled by varying the rate of feed. Stability of sintering is obtained, and a 17% increase in production is recorded.
