Tata Steel has recently completed a significant investment in upgrading one of the coilers on the Hot Strip Mill at its IJmuiden plant in the Netherlands
The investment paves the way for the development of heavier-gauge strip for use in the manufacture of articulated trucks, and of higher-strength steel grades for use in cranes and machine boom arm applications. The result will be that the weight of customers’ finished fabrications can be reduced whilst maintaining strength and integrity.
A number of new steel grades are in development and are being trialled through the upgraded coiler, including Ympress® S700 and Ympress® S960. These grades are becoming increasingly important to lifting and excavating equipment makers.
The upgrade was carried out by metallurgical plantmakers Siemens and SMS Siemag. The coiler has been upgraded with new mandrel and pinch roll equipment as well as with new motors, electrical drives, gears and hydraulic equipment.
The upgraded coiler can supply high-strength steels up to 20mm thick. Core applications for the new steel grades will be those requiring high strength combined with reduced weight, including cranes and construction equipment.
