Title:
DEVICE FOR CONTROLLING FURNACE TOP GAS PRESSURE IN BLAST FURNACE
Document Type and Number:
Japanese Patent JP2000282115
Kind Code:
A
Abstract:
To provide a furnace top gas pressure control device in a blast furnace, with which the furnace top gas pressure in the blast furnace is controlled to be constant.
The furnace top gas pressure and furnace top gas temp. are measured, and to a furnace top gas pressure control signal obtd. by comparing the measured furnace top gas pressure with the preset furnace top gas pressure setting value 8, the furnace top gas pressure correcting signal correctively calculated based on the measured furnace top gas temp. is added.
