Description of the Invention (i) Introduction of the Invention = This invention relates to a method for detecting unmelted debris in an electric arc furnace And a sampling and / or temperature measurement device used in this method. In the process of making steel using an electric arc furnace, the furnace body of the electric arc furnace is charged with a material head and / or other ferrous materials, and these materials are melted by the energy input from the electric arc. When the added material has been melted and the metal bath furnace has reached a preset temperature, the steel system is poured through a tap hole located in the hearth. In order to facilitate the completion of the pouring action and the subsequent plugging action of the tap hole, the tap hole is usually placed in the lateral area of the arc furnace called the arc furnace polygonal working room. The polygonal working chamber itself is a laterally protruding part of the hearth > so that the hearth can easily perform the accessing action from above the outside of the wall surface of the hearth. After the pouring operation is completed, the accessibility described above enables a plug rod to be introduced into the tap hole to plug the tap hole through the plug hole material without removing the top cover of the furnace body. In order to ensure that all solid materials can be completely melted before pouring from the metal bath furnace, the temperature must be measured during the melting cycle. To achieve this, a nozzle containing a temperature probe is usually guided through a debris removal channel in the electric arc furnace so that the probe can be sunk into the metal bath furnace. When the temperature B of the metal bath furnace reaches a certain preset temperature, it can be assumed that no solid residues are present in the hearth and the pouring action system can be started. Due to the debris removal channel system, one and more 4 ^ ^ II ^ ί J. ^ ^ ^ ^ ♦ d ^ ^ n I I SJ «.1 ^ ^ ^ ^ 1 ^, 1 I II ia ^ ^ ^ ^ ϋ II ^ ^ I nnt— ^ ^ I ^ ^ II (Please read the precautions on the back before filling out this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ) A7 4 343 9 2 ^ _______B7______ 5. Description of the Invention (X) The angular working room is at an area opposite to the diameter, so the temperature measurement is performed at an area separated from the tap outlet by a certain distance. Then, the temperature of the steel bath furnace around the tap hole can be estimated or calculated by considering the size of the electric arc furnace and the amount of molten metal contained in the electric arc furnace. The above calculation results are obviously only available in the polygonal shape. Approximate temperature of actual bath temperature in the studio. Therefore, unmelted debris may exist in the polygonal working room, and the iron tap opening may be blocked during the pouring process. The hairpin said: The purpose of this invention is to propose a start-up pouring method which can avoid the disadvantages mentioned above. Another purpose is to describe a measurement and / or sampling device that is particularly suitable for performing this method. Summary of the invention: The purpose of the present invention is achieved by adopting a method for starting a pouring action in an electric arc furnace, which is combined with a polygonal working chamber, and the iron nozzle of the electric arc furnace is located In this polygonal working room, the method includes the following steps: introducing a temperature probe into the arc furnace polygonal working chamber; measuring the temperature of the metal bath furnace in the arc furnace polygonal work; When the temperature exceeds or equals the preset threshold, the pouring action is started.
