With rich engineering experience, HBMER has successfully completed more than 10 EPC projects for metal magnesium smelting plants (equipped with horizontal reduction furnaces), along with over 20 renovation projects and several full-process segmented EPC projects (see some metal magnesium smelting plant cases in the table below). All projects have been highly recognized by customers and have created considerable economic benefits for them. We also possess complete design and installation drawings for more than 10 metal magnesium smelting plants, as well as drawings for over 20 renovation/segmented EPC projects. You are welcome to visit any of the plants we have constructed at any time, and we look forward to your inspection in the near future!

Working Principle:
The horizontal reduction furnace adopts an external heating, horizontal retort design for magnesium smelting. Under high temperature (1200–1250 °C) and high vacuum (≤10 Pa), calcined dolomite is reduced by ferrosilicon to produce magnesium vapor, which is then condensed into crude magnesium. The horizontal structure ensures uniform heating and stable reaction conditions for high‑quality magnesium output.

Key Features:
- High Thermal Efficiency & Energy Saving: Equipped with regenerative combustion and optimized flue gas heat recovery, the furnace significantly lowers fuel consumption and operating costs.
- Uniform Heating: Rational furnace structure and flame distribution ensure consistent heating across retorts, reducing under‑reaction and extending retort life.
- Stable & Reliable: Designed for continuous batch production; vacuum system, combustion control, and cooling system operate steadily under long‑term high‑temperature conditions.
- Flexible Fuel Adaptability: Compatible with natural gas, coke oven gas, blast furnace gas, and other gaseous fuels to match on‑site energy supply.
- Easy Operation & Maintenance: Horizontal retorts support convenient charging, slag removal, and daily inspection, lowering labor intensity.
- Environmental Protection: Low‑NOx combustion and flue gas treatment systems meet strict environmental emission standards.

Technical Highlights:
- External heating horizontal retort furnace
- High vacuum & high temperature reduction process

HBMER Advantage & Technological Innovation:
We deliver full‑scope EPC service including process design, equipment manufacturing, installation, commissioning, training, and startup. With mature engineering experience and independent core technology, HBMER provides reliable, efficient, and low‑consumption magnesium smelting solutions for global customers.

In addition to horizontal reduction furnaces, the high-efficiency vertical magnesium/calcium reduction furnace developed by HBMER can reduce energy consumption by 1/3 and comprehensive costs by 15~30%. It not only contributes to energy conservation and environmental protection but also significantly enhances the market competitiveness of our customers. Currently, more than one-third of magnesium ingots in China are produced using our vertical reduction furnaces, and two of the world's top five magnesium enterprises have adopted our advanced technology.
