sludge stainless steel

01-10-2020· Stainless-steel pickling sludge (SSPS) is a hazardous solid waste, which mainly contains CaSO 4, CaF 2 and a high level of metals such as Fe, Cr and Ni. The high-content of sulfur in the SSPS hinders its adequate treatment and deteriorates the quality of hot ferronickel when the SSPS was used as a feed to the rotary kiln-electrical furnace process (RKEF).
