Problems solved by technology

[0012] The important thing is: if the above methods of continuous temperature measurement can be realized, it only solves the continuous test of molten steel temperature. For the realization of automatic or intelligent steelmaking, it is necessary to know the online data of carbon and phosphorus in molten steel in real time, especially Only the continuous online data of phosphorus can be realized. The current sub-lance model is only calculated based on a set of test data in the mid-stage of blowing to the carbon temperature at the end of blowing.

Embodiment 1

[0043] like Figure 1-4As shown, this embodiment provides a method for continuously detecting the composition and temperature of molten steel. A probe delivery pipe 3 is arranged in the furnace lining 4 of the side wall of the converter; a plurality of detection through holes 2 are arranged on the probe delivery pipe 3 , the detection probes 5 are linearly arranged in the detection through holes 2, a detection probe 5 is arranged in each detection through hole 2, and adjacent detection probes 5 are connected by plugging, so that adjacent detection probes A detachable connection and a test signal circuit are formed between the probes 5; the detection probe 5 in the detection through hole 2 is sent into the converter through a hydraulic cylinder, and the detection probe 5 is directly in contact with the molten steel to directly measure the temperature of the molten steel and composition; the detection probe 5 entering the molten steel is washed away by the molten steel, separate...

Embodiment 2

[0045] like Figure 1-4 As shown, this embodiment provides a device for continuously detecting the composition and temperature of molten steel, including a block 1 arranged in the hearth lining 4 on the side of the electric furnace. Three detection through holes 2 are provided, and a detection probe 5 is respectively placed in each detection through hole 2, and adjacent detection probes 5 in the same detection through hole 2 are connected by plugging. Direct contact with the molten steel in the electric furnace to detect the temperature or composition of the molten steel. When the detection probe 5 at the front end completes the detection, the cylinder pushes the detection probe 5 into the electric furnace so that the detection probe 5 at the front end completely enters the steel. In the water, under the scouring of molten steel, the detection probe 5 at the front end falls into the molten steel.

[0046] In order to prevent molten steel from flowing out along the gap between...

Abstract

The invention discloses a method for continuously detecting ingredients and temperature of molten steel, and relates to the technical field of steel making detection equipment, structural improvementis performed on an existing detection probe to solve the continuous ingredient test problem and continuous temperature measurement problem necessary for intelligent steel making, therefore model intelligent steel making is realized, and intelligent dispatching and management of the temperature of an entire steel mill can also be achieved by the continuous temperature measurement of a steel refining furnace and a molten steel tank, so that various economic and technical indexes are greatly improved. Moreover, the method for continuously detecting ingredients and temperature of molten steel in the invention has the technical effects of less one-time investment, less maintenance cost, low probe cost, reliable detection result, no steel leakage doubt, and the problem in the prior art only continuous temperature measurement can be realized, but continuous detection data of ingredients such as carbon and phosphorus and the like that are necessary for intelligent steel making cannot be provided is solved. The device for continuously detecting ingredients and temperature of molten steel in the invention can realize continuous monitoring of the temperature and ingredients of molten steel.

Description

technical field [0001] The invention relates to the technical field of steelmaking detection equipment, in particular to a method and device for continuously detecting the composition and temperature of molten steel. Background technique [0002] At present, steelmaking equipment such as oxygen top-blown converter, electric furnace, argon blowing station behind the furnace, VD furnace, RH furnace, LF furnace, etc. need to know the temperature of molten steel and the content of some components in time during the operation of the smelting process. [0003] At present, a small number of converters use the sub-lance system. The sub-lance probe is inserted into the molten steel from the converter mouth to take steel samples, measure the temperature of molten steel, measure oxygen, and determine carbon by crystallization. In recent years, a very small number of converters have installed throwing detection systems. Only at the end of blowing, the throwing system is put into the det...
