AI Technical Summary

⚠Technical Problem

The internal rollers of the vertical sintering furnace are easily damaged, and the mounting base is prone to tipping over when pulled out due to the lack of front support, causing the sintered parts to fall off.

⚗Method used

The high-temperature resistant support system is composed of support components, fixed shafts, and support rollers made of alumina ceramic material, and is equipped with lifting support plates and electro-hydraulic rods to achieve automatic support function; cooling is achieved by combining cooling water circulation pipelines.

🎯Benefits of technology

It improves the service life and reliability of moving parts inside the furnace, ensures the safe transfer of sintered workpieces, reduces the temperature of the outer wall of the furnace, prevents thermal deformation and burns to personnel, and enhances the safety and lifespan of the equipment.

Abstract

This utility model discloses a furnace chamber structure for a vertical sintering furnace, relating to the field of sintering furnaces. It addresses the problems in existing technologies where, due to the extremely high temperatures inside a vertical sintering furnace, the lower end of the mounting base is supported by rollers. However, existing rollers, while heat-resistant, are easily damaged inside the furnace. Furthermore, the lack of front-end support when the mounting base is pulled out of the furnace chamber causes it to tip over, scattering the sintered components. The furnace chamber is located within the alumina ceramic inner liner. A placement platform is located at the lower end of the furnace chamber. Support members are fixedly connected to both sides of the lower end face of the placement platform. A fixed shaft is fixedly connected between the two support members at the front and rear ends of the lower end face of the placement platform. Support rollers are rotatably connected to the fixed shafts. By using alumina ceramic support members, fixed shafts, and support rollers to form a high-temperature resistant support system, the problem of traditional metal rollers being easily damaged in high-temperature environments is solved.
