Description

Technical Field

[0001] The invention relates to the technical field of pouring large castings and forgings, in particular to a monitoring and temperature control device for hot processing of large castings and forgings. Background Art

[0002] As is known, when making steel castings, pouring temperature control is crucial. When the poured molten metal enters the mold, the temperature of the molten metal will decrease. When pouring large castings, the mold volume is large, and the time and distance for the molten metal to pass through the mold become longer. The temperature of the molten metal that first contacts the mold will drop sharply, and the viscosity of the molten metal will increase as the temperature drops. The melting point of the molten metal is high, and the fluidity itself is poor. The fluidity will become worse as the viscosity of the molten metal increases. Not only will the mold grooves on some molds be unable to flow into the molten metal, and even bubbles will exist in the molten metal, but there will also be gaps between the mold grooves on the mold and the molten metal, which will affect the quality of the casting. In addition, the cooling and shaping time of the molten metal in the mold is relatively long. For this reason, we have proposed a monitoring and temperature control device for hot processing of large castings and forgings. Summary of the invention
