Converter water leakage monitoring system and method

Abstract

The invention is suitable for the technical field of electrical control, and provides a converter water leakage monitoring system and method. The monitoring system is constructed on the basis of a converter body as well as a matched oxygen lance, a flue and flue accessories; the flue comprises a smoke hood and a plurality of flue sections; the monitoring system comprises a converter body water leakage monitor, an oxygen lance water leakage monitor, a flue water leakage monitor and a flue accessory water leakage monitor. On the basis of an original pressure and temperature linkage water leakage control system and method, water leakage monitoring is conducted on a plurality of water leakage sources, a water inlet flow meter is additionally arranged on a cooling water inlet pipeline of an equipment water leakage source, a water return flow meter is additionally arranged on a cooling water return pipeline, and water inlet and water return flow difference data serve as the basis for judging equipment water leakage, so that the multiple water leakage sources can be accurately monitored in time, the oxygen lance and the converter are controlled to make linkage response in time, and accidents caused by water leakage are avoided.

Description

technical field [0001] The invention belongs to the technical field of electrical control, and in particular relates to a converter water leakage monitoring system and method. Background technique [0002] In the process of converter steelmaking, molten iron and molten steel are high-temperature molten materials. Once the converter enters water, the control system makes a wrong judgment and shakes the furnace. The high-temperature molten iron and molten steel at 1400°C-1700°C cover the accumulated water, and the cooling water will instantly vaporize into The superheated steam expands by 800-900 times in volume, and then generates huge energy to cause it to be ejected explosively, causing major accidents. [0003] In particular, the structure of the converter and its supporting system is complex, including the converter body, oxygen lance, movable fume hood, flue and various accessories, etc., and each part involves high temperature cooling protection. The high-temperature c...

[0002] In the process of converter steelmaking, molten iron and molten steel are high-temperature molten materials. Once the converter enters water, the control system makes a wrong judgment and shakes the furnace. The high-temperature molten iron and molten steel at 1400°C-1700°C cover the accumulated water, and the cooling water will instantly vaporize into The superheated steam will expand by 800-900 times in volume, and then it will generate huge energy to make it blast out, causing major accidents

[0003] In particular, the structure of the converter and its supporting system is complex, including the converter body, oxygen lance, movable fume hood, flue and various accessories, etc., and each part involves high temperature cooling protection.

The high temperature cooling protection usually uses cooling water circulation, resulting in many possible sources of water leakage, and it is difficult to comprehensively check the hidden dangers of water leakage by manual work, which increases the probability of accidents
