Description

Technical Field

[0001] The utility model belongs to the technical field of the application of molten steel casting samples during casting, and particularly relates to a demolding machine for liquid steel samples. Background Art

[0002] Liquid die forging, also known as squeeze casting and continuous casting and forging, is a new metal forming process that combines the characteristics of casting and is similar to die forging. It directly pours a certain amount of molten metal to be cast into a cavity coated with a lubricant, and continuously applies a mechanical static pressure. By taking advantage of the easy flowability of metal during casting solidification and forging technology, the solidified hard shell is plastically deformed, so that the metal crystallizes and solidifies under pressure and the shrinkage cavities and porosity formed due to solidification shrinkage are forcibly eliminated to obtain liquid die forging parts without casting defects.

[0003] During liquid die forging casting operations, there is a sampling and testing process, that is, a molten steel sampler is inserted into the molten steel to drain the sample mold box, and a molten steel sample is prepared through the sample mold box.

[0004] After retrieval: The application number / patent number is 201220418166.1, which discloses a molten steel sample demolding device, belonging to the auxiliary facilities for sampling and analyzing the composition of liquid metals. It includes a bracket, a round table is arranged on the upper surface of the bracket, a through hole is provided at the axis of the round table, the aperture of the through hole is equivalent to the outer diameter of the metal sample mold box, a lever is arranged on one side of the bracket, a hook is arranged at one end of the lever, and the fulcrum of the lever is a rotating shaft, and the rotating shaft is installed on the bracket. The utility model can quickly peel off the sample of the molten steel sampler and the metal sample mold box at a red-hot state of 1000 °C, quickly air-cool the initially solidified molten steel sample for spectral analysis, quickly provide accurate molten steel composition data in front of the furnace, ensure the smelting rhythm, and improve production capacity.

[0005] After analysis: During the use process, it requires multiple people to cooperate manually, increasing the labor cost. At the same time, when manually operating through the lever, there is also a problem that excessive force is applied to push the sample away from the metal sample mold box, which has a certain potential safety hazard; in addition, air cooling also needs to take out the sample and then complete it through a special air cooling device, which is time-consuming and has a cumbersome operation problem, etc.

[0006] Therefore, based on the above problems, the utility model provides a demolding machine for liquid steel samples. Content of the Utility Model
