The operation of converter current dry-dedusting system movable gas hood, is mainly manual operation and controls movable gas hood descending operation with coal gas of converter component content.Manual operation, is mainly artificial judgment, exists error in judgement, judgement to delay and the factor such as maybe cannot judge; With coal gas of converter component content, control movable gas hood, mainly with CO content in coal gas, judge, to H in coal gas
2exceed standard, O
2exceed standard and dust exceeding etc. cannot judge.It is quick-fried that above-mentioned two kinds of operating method very easily cause movable gas hood lifting to cause not in time system to be unloaded in the state of accident, increased converter dry dust-removal system potential safety hazard, reduced equipment life.For this reason, develop a kind of simple in structurely, easy to operate, safe and reliable, labour intensity is low, and the converter smelting dry method dust movable gas hood automatic hoisting control device that working efficiency is high is the key addressing this problem.
