METHOD OF REGULATION OF BLOW DISCHARGE ENTERING BLAST FURNACE

摘要

FIELD: foundry engineering. SUBSTANCE: when air-heater starts filling up signal for forced opening of release valve appears. After release valve tongue gets out of idling motion, signal calls for valve opening cessation. Simultaneously another signal calls for short time increase of blow discharge by means of acceleration of air-blowing unit and switching over pressure regulator for control of release valve position. It increases safety of working system and blow pressure accuracy. EFFECT: enhanced efficiency. 4 dwg
