Abstract

PURPOSE: To maintain the blast temp. of a hot stove at a predetermined level with a simple control circuit by combining control for maximizing the opening of the blast butterfly valve of one of preceding and following hot stoves and regulating the blast butterfly valve of the other with control for adjusting the vol. of cold air mixed.
CONSTITUTION: When blast butterfly valve CB1 of preceding hot stove 1HS is full opened and valve CB2 of following stove 2HS is perfectly closed, valve MB of cold air mixing pipe 1a is opened or closed according to the signal of regulation meter 5, and opening work of valve CB2 is selected according to blast instructions from operation controller 7. Until valve MB is perfectly closed and valves CB1, CB2 are full opened, valves MB and CB2 are alternately worked, and valve CB2 is closed to carry out blast temp. control. During the time from full open of valves CB1, CB2 to perfect close of valve CB1 valves MB and CB1 are alternately worked, and when valve CB1 is perfectly closed, blast temp. control is shifted to the combination of valves MB, CB2 and CB3.
