Hunan Ruiyi Zihuan Technology Co., Ltd.

Hunan Ruiyi Zihuan Technology Co., Ltd. is a university-industry-research cooperation enterprise of Central South University and a national high-tech enterprise. The company has opened up the entire process chain including technology incubation and promotion, equipment development and manufacturing, and general engineering contracting. Adhering to the concept of lean service, it provides customers with comprehensive services from technical consultation to furnace operation. It has now become an overall solution provider with core competitiveness in fields such as clean and efficient utilization of non-ferrous metal secondary resources, comprehensive recovery and safe disposal of heavy metals and arsenic-containing hazardous waste.
The company has a professional R&D team with professors and doctors as the core; a design team with senior engineers and registered professional technicians as the core; and an engineering construction, equipment manufacturing, and factory intelligent transformation team with industry experts as the core. It brings together talents with advantages in metallurgical production and management, environmental protection, factory design, machinery manufacturing, automation, electrical engineering and other industries, and can independently solve various problems arising in the harmlessness, resource utilization and high-value utilization of heavy metals.
With independent intellectual property rights of oxygen-enriched side-blown bath smelting technology as the core, the company has developed a series of engineering technologies and equipment such as recycling of waste lead-acid batteries to regenerate lead, comprehensive recovery and safe disposal of hazardous waste from lead-zinc-copper smelting, oxygen-enriched side-blown smelting treatment of copper-containing sludge, harmless treatment of high-arsenic materials, vitrification of hazardous waste slag and fly ash, low-temperature pyrolysis of organic hazardous waste, and comprehensive recovery of waste lithium-ion batteries. It has formed a series of patented products such as RE-type oxygen-enriched side-blown furnace, RE-type oxygen-enriched side-blown electric heating furnace, pure oxygen rotary furnace, low-temperature pyrolysis furnace, arsenic reduction furnace, etc., and has deeply expanded in fields such as regenerated zinc, regenerated copper, and secondary antimony recovery. The non-ferrous metal recycling industry is developing in the direction of low energy consumption, low cost, high efficiency, and high automation.
