Hunan S. R. M Technology Ltd. is a modern high-tech enterprise integrated with research, development, manufacturing and trade. It has passed the approval of ISO9001: 2008 quality management system and ISO14001: 2004 environment management system, boasting many invention patents and utility model patents. In 2008, it was accredited as the high and new technology enterprise by the Ministry of Science and Technology, Ministry of Finance, and State Administration of Taxation.

The leading product of the company is the molten iron pretreatment desulphurizer for steel industry_coating particle magnesium. Coating particle magnesium is the widely adopted single-blown particle magnesium at home and abroad and the necessary supporting materials for complex (mixed) blowing desulphurization technology. The coating particle magnesium developed and manufactured by our company has won the support and instruction from Chinese and Ukrainian metallurgy experts like Prof. Shevchenko from Ferrous Metallurgy Research Institute of Ukraine Academy of Sciences (chairman of the International Molten Iron Desulphurization Society) and from Ukraine Titanium Metallurgy Design and Research Institute. The quality of the product is at the domestic and international advanced level.

Our company has a 3800 square meters plant and two coating particle magnesium production lines with the annual production capability of 10, 000 tons. The surface coating of magnesium particle is well-distributed and dense, bonding and fastened and is not likely to fall off and to absorb moisture. The quality indexes of the product all have reached the technical standard of the industry, and the indexes such as magnesium content, coating and its content, and grain size gradation and other physical indexes are adjusted according to different manufacturer's desulphurization technology design and desulphurization facility technological parameters. The smooth desulphurization process is guaranteed, which is characterized by stability, high efficiency, low energy loss, no spraying and prolonged service life of lance. The costs of desulphurization are reduced and customized service is set up.
