Description

Technical Field

[0001] This utility model relates to the field of vacuum nitriding furnace technology, specifically to a vacuum nitriding furnace for nitriding alloys. Background Technology

[0002] Nitriding alloys are widely used in steelmaking. In modern steel production, to improve the strength of steel, alloys such as ferroniobium or ferrovanadium are added during the steelmaking process through microalloying to achieve this effect. To fully utilize the microalloying strengthening effect of ferroniobium and vanadium, an appropriate amount of nitriding alloy is generally added during steelmaking to form strong carbonitrides with the microalloying elements ferroniobium and vanadium, thereby enhancing the precipitation strengthening and precipitation strengthening effects of the microalloying elements. Therefore, nitriding alloys are widely used in steelmaking. In the preparation process of nitriding alloys, the vacuum nitriding furnace plays a crucial role. It heats the alloy material to a certain temperature under vacuum or inert gas protection and introduces nitrogen gas to carry out the nitriding reaction, thereby forming a dense nitriding layer on the surface of the material and improving the overall performance of the material.

[0003] Traditional workpiece clamping methods mostly employ manual or mechanical fixtures, which are not only cumbersome to operate but also have poor adaptability to workpieces of different specifications, making it difficult to meet the high-efficiency and automated requirements of modern industrial production. In practical use, existing vacuum nitriding furnaces for alloy nitriding contain workpieces in a fixed state, preventing nitrogen atoms from uniformly penetrating into the workpiece surface, resulting in uneven nitriding of the workpiece surface.

Through the transmission of the toothed belt, the mounting gear drives the two mounting threaded rods to rotate. By the limiting of the limiting rod, the connecting cylinder drives the moving block and the workpiece to move, which can facilitate the user to quickly place or collect the workpiece. By the mounting motor driving the transmission gear to rotate, the meshing of the transmission gear and the rotating gear drives the rotating rod to rotate the mounting box.
