Description

Technical Field

[0001] The utility model relates to the technical field of vacuum melting furnace control, in particular to a vacuum melting furnace waterway operation and water temperature monitoring system. Background Art

[0002] The vacuum melting furnace is powered by water-cooled cables. Therefore, under high-temperature working conditions, cooling water becomes an important medium for melting and cooling alloy ingots. However, the existing alloy melting process has the following defects:

[0003] (I) During smelting, the smelting situation can only be observed through the observation mirror of the smelting furnace, so the inlet and outlet of cooling water cannot be monitored in real time. Since the smelting furnace lacks monitoring of the water channel during the production process, if the water channel is cut off or the connection of the water pipe in the furnace bursts, the smelting furnace will not be able to perform cooling protection, the alloy ingots cannot be cooled when poured out, causing scalding of equipment or water pipes, leading to alloy oxidation, causing equipment damage and product quality accidents.

[0004] (2) During the high-power casting process after the alloy ingot is completely melted, the staff can only pour the alloy liquid directly into the water-cooled mold when pouring the liquid from the crucible on the operating table. The water system of the water-cooled mold is on the back of the smelting furnace. The staff cannot take care of both at the same time and cannot judge whether the water system is operating normally, which easily leads to safety hazards. Utility Model Content
