The two-strand continuous slab caster No. 2 was originally installed in 1998 and is a vertical-curved design. The machine radius is around 9 m and the containment length is approx. 35 m. The caster produces slabs of 200/225/250 mm thick with widths ranging from 1,050 to 2,100 mm, and will be able to reach 2,300 mm width. Steel grades produced include ultra-low, low, medium and high carbon steels, peritectic and HSLA steels and micro alloyed steels.
The revamped slab caster will be equipped with the latest technological packages supplied by Danieli, including: Q-LEVEL+ proactive automatic mold level control system; Q-WIDTH automatic mold width adjustment; Q-INMO+ hydraulically actuated mold oscillator with rolling element technology; Q-COOL dynamic secondary cooling with independent width control; Q-CORE and Q-PULSE dynamic soft reduction, hydraulically controlled via position transducer; Q-OPTIMUM and Q-ROLL segment design for easy maintenance, process flexibility, high reliability, including automatic gap control and air/oil lubrication to bearings; HI-PROFILE advanced on line slab inspection system.
Danieli will be responsible for the design and supply of the complete slab caster, including Danieli Automation Level 1 and interface with existing Level 2 automation systems; it will also provide advisory services during erection and commissioning.
Start-up is expected in the second quarter of 2019 with on-site project execution within 60 days of outage in parallel with a blast furnace shut down.
Slab caster No. 1 in the same steel plant, was also revamped by Danieli in 2012.
