Metallurgical solid waste utilisation

CISDI applies advanced and optimised technological routes to maximise the internal reutilisation of solid wastes. We provide rotary hearth furnace, homogenizing and cold briquetting solutions to various metallurgical solid wastes, contributing to green development of steel plants.

CISDI attends to highly efficient use of excess heat from the steel plant facilities and provides tailored solutions to plant-wide energy systems and energy saving services. We have developed world's leading patented metallurgical slag dry granulation and sensible heat recovery technology and established the test and industrialisation platform.

		Baosteel Zhanjiang iron-bearing solid waste treatment project The world's first metallurgical integrated Fe-bearing solid waste treatment Rotary hearth furnace, homogenizing, cold briquetting and scale treatment systems working in a coordinated and flexible way for treating with plant-wide solid wastes Realising zero Fe-bearing dust emission
		Yanshan Steel rotary hearth furnace Applying CISDI's rotary hearth furnace direct reduction process, achieving highly-efficient environment-friendly reutilisation of iron-bearing dusts and resulting in world-leading indicators。
		Metallurgical slag dry granulation and sensible heat recovery test platform Solutions to high-temperature slag water-free granulation, sensible heat recovery, environmental governance and solid slag particle reutilisation Resulted in over 95% amorphous content of granulated slag and more than 300kg steam recoverable per ton molten slag
