Company Profile


Henan Vulcan Furnace Industry Co., Ltd. was founded in 1963, formerly one of the earliest state-owned large-scale design institutes engaged in the production and research of electric furnaces in China. After the restructuring of the Design Institute in 1999, some technicians founded the Henan Electric Furnace Research Institute, mainly engaged in the production and technical consultation of various electric furnaces. In 2022, Henan Electric Furnace Research Institute integrated a number of domestic and foreign first-line supporting enterprises and changed its name to Vulcan Furnace Industry, located in the High-tech Zone of Luoyang City, Henan Province, China.
Vulcan furnace industry has passed the ISO9001 quality system certification, CE certification, a total of 3 factories, with a total area of 15000 square meters. Vulkan Furnace has more than 10 senior engineers and more than 100 workers.
With nearly 70 years of production experience and excellent quality, we have established long-term good cooperative relations with many large domestic scientific research institutes, research institutions, universities, medical institutions, large production enterprises, and listed companies.
So far, Vulcan electric furnaces have been exported to more than 30 countries and regions such as the United States, France, Russia, Canada, the United Kingdom, Australia, South Korea, Turkey, India, Pakistan, South Africa, Brazil, Thailand, and Singapore. Welcome to contact us and establish a good cooperative relationship!
