UK-based plantmaker Primetals Technologies has announced that it will supply two twin-strand continuous slab casters to Chinese steelmaker Shandong Iron and Steel Group Rizhao Co., Ltd. The casters are designed to produce a total of 4.6 million metric tons of slabs per year, ensuring high quality slabs and flexibility even under fluctuating casting conditions. The casting plants are scheduled to go on stream in June 2017.
The steel for the two continuous casting machines will be produced in basic oxygen steel converters with a total annual capacity of five million metric tons. They will produce slabs with a thickness of 230 millimeters in widths ranging from 1,000 to 1,950 millimeters. The casting speed will reach up to 1.7 meters per minute. The casters will process a wide range of carbon steels, peritectic grades, structural steel, HSLA (high strength low alloy) steels, deep-drawn grades, and various alloys for pipes.
