Description
Technical Field
The utility model relates to a steelmaking check out test set technical field especially relates to a device that is used for detecting molten steel composition and temperature in succession.
Background
At present, a steel-making device, such as an oxygen top-blown converter, an electric furnace, an argon blowing station behind the furnace, a VD furnace, an RH furnace, an LF furnace and the like, needs to know the temperature of molten steel and the content of partial components in time during smelting process operation.
At present, a small part of converters adopt a sublance system, and a sublance probe is inserted into molten steel from a converter mouth to sample steel, measure the temperature of the molten steel, measure oxygen and crystallize and fix carbon. In recent years, a few of converters are provided with a throwing type detection system, a detection probe is thrown into the converter from a converter mouth only in the last stage of blowing to detect the temperature and the oxygen activity of molten steel, most of the other converters without the two test systems are inverted before tapping and subjected to temperature measurement and sampling from the converter mouth, and most of unequal steel sample components in a steel mill are reported by a laboratory to tap steel.
The electric furnace is used for measuring and sampling temperature from a furnace mouth.
And the argon blowing station behind the furnace and refining equipment such as a VD furnace, an RH furnace, an LF furnace and the like are also used for measuring temperature, oxygen and sampling by using a disposable probe by an operator.
From the above, it can be seen that the current detection method cannot meet the requirements of the steelmaking operator on the real-time continuous important components and temperature of molten steel.
The operator can not accurately know the current molten steel composition and temperature, so that the operation is blindly operated by experience, the economic and technical indexes are reduced in all aspects, and quality and production accidents occur.
Somnolence for optimizing one-touch steelmaking (intelligent steelmaking) has not been mentioned because there is no necessary continuous carbon and phosphorus and temperature data.
The continuous detection of the oxygen content, the phosphorus content and the carbon content in the molten steel is a problem which is not solved so far.
For many years, many methods have been tried to solve the problem of continuous temperature measurement of molten steel, because molten steel has a layer of thick or thin steel slag in the steel-making furnace and on the molten steel surface in the steel-making furnace after tapping, the layer of steel slag causes that infrared temperature measurement and other non-contact temperature measurement techniques are difficult to implement, in order to overcome the influence of slag on detection, people turn to open a hole from the furnace wall or the furnace bottom of the converter or the electric furnace (some are axially opened from an argon blowing brick), and argon or other gases are blown into the hole to block the outflow of molten steel, one method is to analyze and calculate the light radiated from the hole to the outside to obtain the temperature of the molten steel, and the other method is to measure the temperature by infrared rays through; the optical fiber wrapped by the high-temperature material is conveyed into the molten steel through the hole, and the temperature is calculated by analyzing the data transmitted by the optical fiber; and a plurality of thermocouples are embedded in the furnace lining in a decreasing mode, and no method is accepted by the steel works in China until now due to the influence of the service environment of the steel works on various testing methods and the consideration of safety.
At present, no related technical solution exists for continuous test of molten steel in a molten steel tank behind a furnace, and the smelting problems of a VD furnace, an RH furnace and an LF furnace are still solved.
Importantly, the method comprises the following steps: if the continuous temperature measurement methods can be realized, the continuous test of the molten steel temperature is only solved, for realizing automatic or intelligent steelmaking, online data of carbon and phosphorus in molten steel, particularly continuous online data of phosphorus, must be known immediately, and the conventional sublance model is only calculated according to an empirical model of a group of test data in the middle stage of converting to the carbon temperature harmony at the converting end point.
