Turkish-steel maker Tosyali Holding has recently ordered a new slab caster from Primetals Technologies. Tosyali is aiming to expand in the Algerian market by implementing the slab caster together with a new hot-strip mill at its site in Bethioua, located in the north-western part of Algeria. The commissioning of the slab caster is scheduled for summer 2024. The 2-strand slab caster has a radius of ten meters and a metallurgical length of 25 meters. With a capacity of 3.4 million tons of qualified slab per year, it will produce slabs ranging in thickness from 200 to 250 millimeters and in width from 900 to 1,800 millimeters. Casting speeds will be up to 1.6 meters per minute. The mold level is controlled by LevCon, an automatic mold-level control system with auto start casting functions and auto-adaptive dynamic bulging compensation. Another important feature is Flow Master combined electromagnetic stirring and breaking in the mold, resulting in high internal strand quality at high casting speeds.Sophisticated automation systems from Primetals Technologies make sure the casting machine is optimized for both current and future needs. The Level 2 automation package ensures high and consistent quality throughout the process. DynaPhase, a thermodynamic phase transformation model, uses parameters like thermal enthalpy, thermal conductivity, and density to calculate how the liquid steel is composed and how it will behave during solidification. Dynacs 3D, a secondary-cooling model, calculates the full 3D temperature profile at any position along the strand to achieve optimal adjustment of secondary-cooling set points. At the same time, this model reveals the point of final strand solidification for best possible control of cooling. DynaGap SoftReduction 3D, a fully automatic roll-gap control system, allows dynamic soft reduction to minimize centerline segregation for improved internal strand quality.In addition to these systems, the 2-strand slab caster will also feature the Mold Expert Fiber technology, which increases plant availability and cuts the time needed for maintenance. While enabling detailed monitoring of the processes taking place in the caster mold, this systems’ core aim is to alarm operators to the possibility of a caster-mold breakout at the earliest possible stage.Another key feature to this slab caster is the comprehensive quality tracking system Through-Process Optimization. An important part of TPO, Through-Process Quality Control has the following main tasks: inspecting slabs, analyzing root causes for defects, tuning the automated quality rating, process optimization, and recording and visualizing data.Leading steel technology supplier Tenova was recently awarded a contract for the supply of a new Electric Arc Furnace at the Tosyali Bethioua plant
