The multi-layer lifting device for heat treatment in a well furnace is an efficient tool used for heat treatment operations in well furnaces. It is made of high-quality materials that are resistant to high temperatures and corrosion, with an exquisite design that can carry multiple layers of workpieces and achieve batch processing. The lifting device is designed with a multi-layer structure, which improves space utilization, shortens heat treatment time, and ensures uniform heating of the workpiece, thereby improving the quality of heat treatment. Widely used in fields such as metal processing and mechanical manufacturing.
