HM-9-17 Vacuum Atmosphere Box Furnace

Product Introduction

HM-9-17 is a 1700°C vacuum atmosphere box furnace for universities, research institutes, and industrial or mining enterprises carrying out atmosphere-protected sintering or atmosphere reduction. Its 300*200*200 mm chamber is configured for larger advanced-material batches and small-batch process development, with a 9kw rating and 380V50/60HZ supply listed for this model. The furnace is specified with a uniform temperature field, fast heating, energy-conscious operation, and the ability to introduce multiple gases. A polished furnace door with an embedded silicone strip supports sealing, while lightweight alumina ceramic fiber provides insulation and resistance to rapid heating and cooling. Double-layer forced-air cooling is used for the furnace body. Intelligent temperature control provides 30-50 segment programmable PID self-tuning, automatic heating, and automatic cooling. Optional RS-485 communication and control software can support computer-based start, stop, pause, heating-curve setting, curve storage, and historical-curve recording. The model is suited to the listed advanced ceramic, metallurgical, refractory, new-material, and special-material work. For the matching technical configuration, see the related HM-9-17 product guide.
