RHF-1400L is a roller table atmosphere furnace with 1500ºC max working temperature and 112-liter capacity ( L80xW40xH35, cm). The furnace is designed for simulating a big continuous kiln to find suitable sintering parameters at a low cost, and it is excellent for making cathode materials and hard carbon for a pilot test of battery research.
