Novokramatorsk Machine Building Plant fulfills an order for the Romanian plant of Liberty Steel

Novokramatorsk Machine-Building Plant (NKMZ) manufactured in June the second batch of five segments of a slab continuous casting machine (CCM) for Liberty Galati (Romania). The first five such segments were manufactured and shipped to Romanian metallurgists in March this year. Having carried out the incoming control of the received equipment, the customer confirmed the high quality of its manufacture.

NKMZ has been delivering such segments entirely to a non-CIS country for the first time in the last two decades. Previously, for the Liberty Galati metallurgical plant, the plant produced only certain elements of this nomenclature. And in 2020, Romanian metallurgists signed a contract with the division of metallurgical and mine-tunneling equipment of NKMZ for the manufacture of ten segments. They made this decision, taking into account more than twenty years of experience of the Ukrainian enterprise in the manufacture of various segments of slab continuous casting machines, both according to their own engineering and according to the customer's drawings. They were completely satisfied with the deadlines for the execution of the order, named by Novokramatorsky.

The segment is one of the most critical units of the slab caster, which is designed to support and move a continuous cast ingot of a wide rectangular profile.

This project was carried out by the Novokramatorsk employees according to the engineering of the customer, who laid down the highest requirements for this equipment, both in terms of the durability of its individual units and the accuracy of its manufacture. At the same time, some nodes of the segment have been improved. Thus, additional axial cooling channels have been added to the roller assemblies, which makes it possible to significantly increase the thermal fatigue strength of the roller surface and, accordingly, the durability. Also, the mechanisms for adjusting the size of the gap between the segment rollers have been changed, which made it possible to increase the range of standard sizes of cast slabs.
