Asil Çelik Orders Turkey’s First 3-Roll RSB from FRIEDRICH KOCKS

In this consortium, KOCKS is responsible for the supply of a heavy-duty Reducing & Sizing Block RSB®. The RSB equipped with four stand positions is designed for operation of 3-roll stands with a nominal roll diameter of 370 mm. The 3-roll block will be implemented in the 400.000 t/a medium section mill behind the roughing and intermediate mill consisting of 18 HV 2-high stands. After re-commissioning of the mill the RSB will finish roll the total straight bar production in the range from 19.0 – 100.0 mm diameter round and from18.0 – 80.0 mm hexagon onto the cooling bed in top SBQ-quality with excellent tolerance and ovality as well as perfect surface finish.
 
The RSB allows rolling to be performed out of only one pass series in the roughing and intermediate mill and thus reduces the number of the required feeders significantly. Any desired finished dimension of the whole dimensional range can be produced in any desired sequence with a small number of roll sets and just a few stand changes in the RSB. The rolling configuration program BAMICON calculates optimum adjusting values for rolls and guides, as well as the driving motors speeds and gear stages depending on the requested finished product.
 
The scope of the KOCKS supply comprises the 3-roll Reducing & Sizing Block with automatic quick stand changing system, the roll shop with quick roll change, the mill configuration program BAMICON, and CAPAS, the computer-aided system for accurate adjustment of rolls and guides of the 3-roll stands in the roll shop. The supply package is completed by the training of customer personnel and the supervision of erection and commissioning.
 
This is the basis for a trouble-free, economic production of top quality SBQ bar. Implementing the first 3-roll Reducing & Sizing Block in Turkey into their medium section mill will enable ASIL ÇELIK to strengthen and even expand their leading position as the largest domestic producer of quality steels.
 
The delivery time of the 3-roll heavy-duty RSB is 12 months FOB.
