Product Overview
The JRN-MTT series tubular furnace of Jinruina adopts a double-layer air-cooled structure, and the furnace is formed by high-temperature vacuum adsorption of high-purity alumina ceramic fibers. It is composed of two semicircular furnace structures, making it easy to start; High temperature control accuracy, safe and reliable; The heating element adopts HRE molybdenum containing resistance wire/silicon carbon rod/silicon molybdenum rod, with fast heating rate, oxidation resistance, and corrosion resistance; The stainless steel flanges at both ends have high sealing performance, making it easy to pre vacuum, and the vacuum degree can reach 6.67x10-5Pa;
Product Usage: Mainly used for melting, sintering, and analysis of metal materials, non-metallic materials, and other compounds in laboratories and operating enterprises of universities and research institutes under controlled atmosphere or vacuum
