[0002] In modern industry, high-strength, atmospheric-pressure sintered silicon carbide products are widely used in key industries such as machinery manufacturing, aerospace, and energy due to their excellent hardness, wear resistance, and chemical stability. However, existing silicon carbide product manufacturing equipment has significant defects in the cooling process. Sintered silicon carbide products are often cooled statically, leading to uneven heat dissipation on the product surface. This easily results in localized overheating or uneven cooling, affecting not only the physical properties and dimensional accuracy of the products but also potentially generating internal thermal stress, reducing the overall quality and lifespan of the products. Furthermore, traditional equipment lacks flexibility in adjusting the support height, failing to precisely adjust according to the actual height of the silicon carbide products. This limits the equipment's applicability to different product specifications and increases production limitations. Utility Model Content

This is used to convert rotary motion into linear motion and has the functions of high temperature resistance and dust prevention. It is usually made of high temperature alloy and mainly consists of a threaded rod and a nut. The rotating threaded rod converts rotary motion into linear motion through the action of the nut to achieve position adjustment. A bracket 11 is threadedly connected to the outer surface of the lead screw 10. Multiple brackets 11, lead screws 10 and fixed frames 9 are provided and are evenly distributed on the rotating rod 8.
[0023] Two rotating rods 8 are provided, both located inside the main body 1 of the production device.
