Innovation in Harmful Metal Slag Treatment Technology
The slag washing furnace technology, which holds two patents, is a unique technology in the world. It effectively integrates the heating technology of the slag washing furnace, the reduction process of the submerged arc furnace, and the power supply technology of the electric arc furnace. As a result, this technology was granted two patents by the State Intellectual Property Office in August 2012 and February 2013:
Water-Cooled Furnace Cover High-Temperature Lined Slag Washing Furnace, Patent No. ZL 2011 2 0412021.6.
Two-Step Reduction Method for the Reuse of Stainless Steel Oxide Scale, Patent No. ZL 2011 102516277.9.
The invention of the slag washing furnace offers significant economic and social benefits. It not only aligns with national policies on circular economy and comprehensive resource utilization but also adheres to the country’s environmental protection policies.
