Method of and device for setting carbon, temperature and oxygen detecting probe in steel making converter

Abstract

The present invention discloses method of and device for setting carbon, temperature and oxygen detecting probe in steel making converter. Carbon, temperature and oxygen detecting probe is set into steel making converter obliquely via the material feeding pipe in the sealing fume hood. The device includes a frame, a probe bin, a paper tube turning tank, a paper tube guiding board, a paper tube pusher, a probe guide pipe, and a paper tube holder. The present invention has low cost, simple operation and easy application in automatic smelting process, and may be applied in replacing available detection.

Description

technical field [0001] The invention relates to a detection technology for temperature measurement, carbon determination and oxygen determination of molten steel in converter steelmaking, and specifically refers to a method and device for putting in a probe for detecting carbon, temperature and oxygen in a steelmaking converter. Background technique [0002] In the production process of converter steelmaking, it is necessary to accurately detect technical indicators such as temperature, carbon content, and oxygen content of molten steel in the converter molten pool, especially the technical indicators of the final molten steel to ensure the quality of the final steel product. The traditional detection method is to turn the converter down when it is in a vertical state, manually sample the molten steel, measure the temperature, carbon content and oxygen content of the sampled molten steel through the detection probe, and determine the technical indicators of the end point of t...

Problems solved by technology

However, at present, only a few large-scale steel mills in China, such as Wuhan Iron and Steel, Baosteel, etc., have adopted sub-gun detection technology. This is because the sub-gun equipment has a large space. Generally speaking, only steelmaking converters with a capacity of 150 to 200 tons or more can be installed with sub-lances. However, domestic steelmaking converters with a capacity of less than 150 tons are relatively large, and many steelmaking plants are limited by converter specifications and do not have the ability to install sub-lances. The space and place of the equipment, so the only way to continue to use the backward manual detection method

In addition, the investment, maintenance and use costs of sub-gun equipment are extremely high. A set of sub-gun equipment requires an investment of about 20 million yuan and a maintenance and use cost of about 4 million yuan. This is not worth the candle for medium and small converters.
