Problems solved by technology

[0005] Therefore, the purpose of the present invention is to aim at the explosion venting control measures in the prior art, which are summarized through production practice, but in the actual operation, they are all controlled manually, interfered by human factors, and the degree of automation is low, and these measures are not comprehensive. The problem is to provide a control method for dry dust removal and explosion relief of the converter. The control method for dry dust removal and explosion relief of the converter includes an automatic control method for explosion relief and an auxiliary operation method. The automatic control met...

Abstract

The present invention discloses a converter dry method dust-removing explosion-venting control method, and belongs to the technical field of converter dry method dust-removing. In the prior art, the explosion-venting measures have problems of manual control, interference by human factors, low automation degree, and no comprehension. In order to solve the problems in the prior art, the present invention provides a converter dry method dust-removing explosion-venting control method, which comprises an explosion-venting automatic control method and an auxiliary operation method, wherein the explosion-venting automatic control method comprises that the explosion-venting automatic control system arranged in the converter automatic control system performs the explosion-venting control measure during the converter opening blowing process and the explosion-venting control measure during the converter blowing smelting process through fan rotation speed control, converter flue cover lifting control, inert gas blowing-in setting, oxygen gun flow rate program setting, feeding frequency and feeding quantity control, electrostatic dust remover double pendulum valve setting, and electrostatic dust remover oxygen content monitoring. The method of the present invention is used for the explosion-venting control in the converter dry method dust-removing process.

Description

technical field [0001] The invention specifically relates to a control method for dry dedusting and explosion relief of a converter, and belongs to the technical field of converter dry dedusting. Background technique [0002] In the converter dry dedusting blowing process, explosion venting will lead to the interruption of converter blowing, and it takes nearly 20 minutes to carry out blowing again after each explosion venting, which not only causes damage to the equipment but also greatly affects the production rhythm, which seriously restricts It has ensured the realization of the production and efficiency of the steelmaking plant. [0003] Due to the intermittent nature of converter production, the entire flue gas cooling and dedusting system must alternately accept atmospheric and flammable CO, H 2 flow within it. From a structural point of view, explosion venting can only occur inside the electrostatic precipitator. The role of the electrostatic precipitator is to co...
