[0028] like Figures 1 to 10 As shown, a novel material rack for an industrial furnace includes a material frame base 2, a material tray rack 1, and a lifting rod 3. The lifting rod 3 is installed on the material frame base 2, and the material tray rack 1 is placed on the material frame base 2 and snapped onto the lifting rod 3. The material frame base 2 includes an outer ring 21, an inner heat-conducting ring 23, radial ribs 22, and a lifting heat-conducting ring 24. The inner heat-conducting ring 23 and the outer ring 21 are connected by radial ribs 22. The outer ring 21 is provided with lifting heat-conducting rings 24, and reinforcing ribs 25 are provided between the outer ring 21 and the lifting heat-conducting rings 24. There are four lifting heat-conducting rings 24 arranged in a ring on the outer ring 21. Both the lifting heat-conducting rings 24 and the inner heat-conducting rings 23 are tubular structures with upper and lower through holes in the middle. The tube walls of the tubular structures are provided with heat exchange holes. The material tray rack 1 includes an outer arc part 1. 1. The material tray includes an inner heating ring 13, a material tray radial rib 12, and a snap-fit ​​heating arc ring 14. The outer arc part 11 of the material tray is connected to the snap-fit ​​heating arc ring 14 to form an annular part. The annular part and the inner heating ring 13 of the material tray are connected by the material tray radial rib 12. The outer arc part 11 of the material tray and the snap-fit ​​heating arc ring 14 are connected to each other at intervals and are evenly distributed on the annular part. A material tray reinforcing rib 15 is also provided between the outer arc part 11 of the material tray and the snap-fit ​​heating arc ring 14. The inner heating ring 13 of the material tray is a tubular structure with heat exchange holes on the tube wall. The snap-fit ​​heating arc ring 14 is an arc-shaped tube wall structure with heat exchange holes on the tube wall. The lifting rod 3 includes a base 31 and a rod body 32. The base 31 is installed at the bottom of the rod body 32. The rod body 32 has a fishing hole 33 at the top. The radial cross section of the rod body 32 is cross-shaped.

[0029] This invention features heat exchange holes on the lifting heating ring 24 and the heating ring 23 inside the material frame, as well as on the heating ring 13 inside the material tray and the snap-fit ​​heating arc ring 14. During heat treatment, as the circulating air inside the industrial furnace conducts heat, the heat flow first enters the arc space within the lifting heating ring 24, the heating ring 23 inside the material frame, the heating ring 13 inside the material tray, and the snap-fit ​​heating arc ring 14, and then conducts heat towards the workpiece through the heat exchange holes. The heat-treated workpieces on each layer of the new material rack in the industrial furnace receive more uniform heat, improving the uniformity of the workpiece's heating and the yield rate. By stacking multiple layers of the material tray rack 1 on the material frame base 2, the number of parts processed in a single heat treatment is increased, thereby improving the heat treatment efficiency.
