に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a '8-direction' for cooling the coil of an electromagnetic mold level meter (EMB) installed on a continuous casting plate.

される。(Prior art and its problems) Measuring the level of molten metal in the continuous casting mold in a well-defined and stable manner and controlling it to a constant level improves slab quality, saves labor, and stabilizes operations. It is extremely important in terms of For this reason, the level meter used to measure the level of the molten metal in the mold is required to have not only detection accuracy and responsiveness, but also durability and ease of handling, all of which are required to be of a fairly high level.

に至っている。By the way, the electromagnetic type in-mold level meter (KMB) is less safe than the r-ray transmission type (R1 type) in-mold level meter that uses radiation, and because it is installed on the upper end surface of the mold copper plate. It has many advantages such as easy installation and removal, good workability, good detection time and responsiveness, no influence of mold powder, and no change in detection characteristics over time. . For this reason, the development of this electromagnetic mold level meter has been progressing in recent years (Japanese Unexamined Patent Publication No. 54
-53621), and has come to be used in actual operations.

てメンテナンス性を向上させることを目的としている。However, in order to improve the level of hot water inside the electromagnetic mold, we manufactured a coil block with a cooling water passage, and installed the coil on the upper end of all mold tube openings. Manufacturing of coil blocks such as ceramic coating is complicated and manufacturing costs are high. The coil block is considerably bulkier in both size and weight than the coil body, and requires a cooling water hose, making it difficult to handle it like a castle. In addition, problems such as poor insulation due to water leakage or intrusion of water vapor in the atmosphere inside the mold cover, resulting in a shortened coil life, were inevitable. It was invented to solve the problem of electromagnetic mold (c) scene level meter coil (
F, MB coil) is thoroughly cooled in a cooling gas atmosphere,
Another purpose is to prevent poor insulation and improve the durability of the coil, and to improve maintainability by making the coil block into a compact box.
