Description

Technical Field

[0001] This utility model relates to the field of carburizing equipment technology, specifically a vacuum furnace carburizing system. Background Technology

[0002] Vacuum furnace carburizing systems are primarily based on the principle of gas carburizing. In a vacuum environment, carburizing gases (such as propane or methane) are introduced into the furnace. Under high temperatures, the carburizing gases decompose to produce active carbon atoms. These active carbon atoms are adsorbed onto the workpiece surface and gradually diffuse into the workpiece, thereby increasing the carbon content on the workpiece surface and forming a carburized layer of a certain thickness, thus improving the surface hardness, wear resistance, and fatigue strength of the workpiece.

[0003] Vacuum carburizing furnaces for large workpieces require the workpiece to be hoisted to the side of the furnace before it can be carburized, and then various equipment is used to send the workpiece into the furnace. This process is quite inconvenient. Utility Model Content
