Oxygen blowing control method for dry dedusting explosion suppression of converter

Abstract

The invention discloses an oxygen blowing control method for dry dedusting explosion suppression of a converter. Multiple stepped climbing three-dimensional curves for controlling the oxygen blowing amount of the converter are established according to different steel types, and parameters of the curves are determined according to actual data of the production environment. The parameters of the curves are recorded in a database, the parameters in the database are corrected at any time according to the data of the actual production environment, and an optimal curve is obtained. Different stepped climbing three-dimensional curves are selected at different blowing stages, and the ascent control function of the oxygen flow at the initial blowing period, the middle blowing period, the rear blowing period and the reblowing stage is satisfied. According to the method, dry dedusting explosion caused by re-gun-discharge after blowing is interrupted can be effectively restrained, stable production of a converter smelting and dry dedusting system is guaranteed, the smelting period is shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of converter dry dust removal, in particular to an oxygen blowing control method for converter dry dust removal to suppress explosion. Background technique [0002] Converter dry dedusting technology is currently used by most converters. Compared with traditional wet dedusting, this method has significant advantages in water saving, power saving, and small footprint. It is the best way for enterprises to save energy, reduce consumption and improve efficiency. Important measures, dry dedusting is the inevitable development direction of converter gas dedusting. However, in actual production, the problem of dry dust removal and explosion relief has always been an important factor affecting the stable production of converters, restricting the wide application and promotion of dry dust removal. Explosion venting is due to the rapid change of the internal pressure of the electrostatic precipitator to the take-off pressure ...
