Section 5. STEEL AND FOUNDRY WASTES PROCESS AND ENVIRONMENTAL CONSIDERATIONS INVOLVED IN THE SELECTION OF HYDRAULIC AND LUBRICATION FLUIDS FOR A MODERN HOT STRIP MILL Conrad A. Perl, Staff Specialist T. A. Hewitt, Engineer D. L. Vice, Process Design Engineer Water Technology Group Stelco, Inc. Hamilton, Ontario Canada L8N 3T1 Henry K. Miyamoto, Project Manager MacLaren Plansearch, Inc. Toronto, Ontario Canada MGR 1T7 INTRODUCTION Lake Erie Works (Figure 1) is situated on 1660 hectares at Nanticoke, Ontario, on the north shore of Lake Erie approximately 70 km south-west of Hamilton. It is an integrated steelmaking facility with Dock and Raw material handling systems, a Coke Oven Battery, a Blast Furnace, two Basic Oxygen Furnaces, a Slab Caster (BOSC) and a 2050 mm Hot Strip Mill. The rated plant capacity is 1.4 million tonnes/year. Industrial water is supplied by the Ontario Ministry of the Environment (MOE) from Lake Erie. Water leaving the works is treated at the Blowdown Treatment Plant (BDTP) and discharged to a holding pond (Pond #4) which overflows to Lake Erie. The Lake Erie Works water systems were designed to minimize treatment costs and environmental impacts [1]. For these reasons the following principles were adopted in the design process: • recirculate process water; • provide local treatment when required; • use existing centralized blowdown treatment plant; • use up-to-date technology. BACKGROUND The 2050 mm Hot Strip Mill (HSM) was designed with a 1600 1/s recirculated process water loop that included the following local treatment (Figure 2): • sedimentation (9.5 ml lagoon) • filtration (8.5 l/m7s) • evaporative cooling tower The process water loop operates at about two cycles of concentration with a maximum blowdown rate of 50 1/s. After cascading the blowdown through the BOSC module, it is treated at the Blowdown Treatment Plant (Figure 3). Water treatment steps at the Blowdown Treatment Plant include: • reactor clarifier • low rate filtration (3.4 l/m2/s) The Hot Strip Mill's four rolling stands are supported by six hydraulic systems and seven lubrication systems. 121
