Abstract
The utility model relates to a water-leakage monitor for steelmaking water cooling oxygen guns, and is suitable for the steelmaking field of the converter and the steelmaking electric furnace. The utility model comprises an NO. 1 oxygen gun 5, an NO. 2 oxygen gun 6, and a steelmaking furnace 11. The utility model is characterized in that the oxygen gun 5 is provided with a cut-off valve 1, a cut-off valve 3, a flow meter 2 and a flow meter 4; the oxygen gun 6 is provided with a cut-off valve 8, a cut-off valve 10, a flow meter 7 and a flow meter 9. The forecasting accuracy of the water leakage of the oxygen gun is minus or plus one thousandth to 0.2 thousandth. Through measuring the cooling water inlet flow quantity and the cooling water outlet flow quantity of the steelmaking oxygen gun, the utility model utilizes the computer monitoring system to analyze and contrast values, carries out the automatic monitoring on the cooling water leakage, sends the water leakage signal to the lifting system of the oxygen gun to control, and eliminates the accident potential of the water leakage.
Description
The utility model is applicable to field of steel-making, comprises converter and Electric furnace steel making.
The oxygen rifle is that the important of steel-making established each, and complex reaction all realizes by the oxygen supply of oxygen rifle in the stove.In converting process, the molten bath chemical reaction has caused molten steel, slag seriously to wash away the oxygen rifle.Thereby the oxygen rifle is the worst equipment of Working environment in the STEELMAKING PRODUCTION, also is safe maximum hidden danger.Especially the generation of oxygen rifle leakage accident will cause great loss to steelmaking equipment and personnel safety.And judge that in the past the method for leaking is only according to people's visual inspection, its accuracy rate is low, is subjected to human factor and environmental influence big, accident rate can not be dropped to minimum.
The purpose of this utility model is by the measurement to steel-making oxygen gun cooling water Inlet and outlet water flow, utilize computer supervisory control system to analyze contrast number, water coolant leaked monitor automatically, the signal that will leak transmits oxygen supply rifle lifting system and implements control, eliminates leakage accident hidden danger.
The utility model relates to a kind of steel-making water cooled oxygen lance water leakage monitoring device, this device has comprised oxygen rifle 5 No. 1, No. 2 oxygen rifles 6, steel melting furnace 11, it is characterized in that trip valve 1, trip valve 3, under meter 2, under meter 4 have been installed on the oxygen rifle 5, trip valve 8, trip valve 10, under meter 7, under meter 9 have been installed on the oxygen rifle 6.
Inlet and outlet water flow to the steel-making oxygen gun cooling water is measured respectively, and according to mass conservation theorem, if water coolant does not have seepage, then oxygen gun cooling water Inlet and outlet water flow should equate.Do not leak if both differences of oxygen gun cooling water Inlet and outlet water flow can be thought ± 1 ‰, just can conclude that the oxygen rifle leaks if exceed this scope.In converting process, detecting the oxygen rifle that is blowing has drainage, keeps in repair with regard to carrying rifle rapidly and moving on to the maintenance area, simultaneously an other oxygen rifle is forwarded to the blowing state and continues oxygen blast.
The utility model oxygen rifle forecast precision that leaks is ± 1.0-0.2 ‰, by measurement to steel-making oxygen gun cooling water Inlet and outlet water flow, utilize computer supervisory control system to analyze contrast number, can leak to water coolant and monitor automatically, the signal that will leak transmits oxygen supply rifle lifting system and implements control, eliminates leakage accident hidden danger.
Fig. 1 is the steel melting furnace oxygen rifle predictor structure iron that leaks.
Below in conjunction with accompanying drawing the utility model is further specified.Adopt computer supervisory control system that key parameters such as oxygen rifle leakage accident and control of lance position are monitored automatically at 30 tons of converter oxygen guns.In the oxygen rifle leaks the accuracy of detection scope, just can effectively detect the generation of the situation of leaking, thereby system automatically performs the generation that a series of security measures is avoided accident then.Simultaneously because system can accurately detect the height of oxygen rifle.For condition has been created in the correct control of stokehold oxygen lance position.
This device can detect the water loss of 0.1 ton/h of oxygen gun cooling water, reports to the police rapidly, carries rifle.
