Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment tools for steel smelting, in particular to an integrated device for temperature measurement, sampling and material pressing of an intermediate frequency furnace. Background Art

[0002] As the main equipment for metal melting in enterprises such as casting, special steel, and non-ferrous metal smelting, the intermediate frequency furnace heats metal by using the principle of electromagnetic induction.

[0003] During the melting process of the intermediate frequency furnace, it is necessary to sample and measure the temperature of the molten steel to understand the composition and temperature of the molten steel, provide data support for the subsequent refining process, and thus smelt high-quality qualified molten steel.

[0004] Traditional temperature measurement and sampling methods mainly rely on manual methods of workers to measure the temperature and obtain samples of molten iron or molten steel. The operator needs to hold a temperature measuring gun and a sampler several meters long and stand near the furnace mouth to perform temperature measurement and sampling operations respectively. This not only has a slow speed, but also the splashing of molten steel easily causes the risk of burns. At the same time, the relative position of the gun insertion depends entirely on the operator's experience and naked eye judgment. The position and depth of each temperature measurement and sampling are different, resulting in unstable measurement results.

[0005] In addition, when smelting in an intermediate frequency furnace, scrap steel materials need to be added to the intermediate frequency furnace. Due to the irregular size and shape of the material blocks, it is easy to cause material jamming (the material blocks are stuck at the furnace mouth). The current practice is that workers use tools such as shovels and steel pipes to go forward and poke and press downward to press the material blocks into the intermediate frequency furnace. However, this method is obviously dangerous, and at the same time, the working environment of the workers is very harsh. Summary of the Invention
