The key component in hot briquetting is a specially designed roller press. The entire plant for the hot briquetting of sponge iron typically consists of:
The direct-reduced iron is discharged hot from the reduction process and pushed into the nip between the two synchronized, counter-rotating rollers. The briquettes are formed by pockets in the rollers. This process typically takes place at temperatures of around 700 °C and specific pressing forces of up to 180 kN/cm of active roller width. The continuous string of briquettes emerging from the rollers is guided by a heavy chute and usually separated into singles.
Roller presses for hot briquetting are equipped with additional features to cope with the high operational temperatures:
