Description

Technical Field

[0001] The invention relates to the technical field of alloy smelting, in particular to a high-temperature alloy smelting protection mechanism. Background Art

[0002] High-temperature alloy smelting refers to a method of melting the raw materials that make up high-temperature alloy materials into alloys at high temperatures. This is one of the processes for preparing high-temperature alloy materials, and the requirements for materials are relatively high, because high-temperature alloys are mainly used for key components of aviation and spacecraft. High-temperature alloys have diverse components and contain a large number of easily oxidized elements, so the requirements for impurity elements and gas content are very strict. High-temperature alloy smelting process is the key to obtaining high-temperature alloys with excellent performance. By selecting an appropriate smelting process, the alloy composition can be effectively controlled, impurities and gases can be removed, thereby improving the performance and quality of the alloy. Continuous exploration and research of new smelting processes and technologies will further improve the performance and quality of high-temperature alloys.

[0003] The tripping caused by the over-high shell temperature of the smelting furnace is a safety mechanism designed to prevent damage to equipment and operators. In the normal alloy smelting process of the existing smelting furnace, the shell temperature is often high, triggering the protection chain and causing the tripping. After on-site confirmation by the maintenance personnel, it is found that the shell temperature is not high, but is actually caused by a false temperature signal. However, the tripping will cause the smelting process to stop suddenly, thus affecting the production plan and output. After the alloy smelting is completed, the staff is too close to the furnace body to unload the furnace alloy solution, which is prone to scalding. Summary of the invention
