The Novokramatorsky Mashinostroitelny Zavod designed and manufactured a complex of equipment for a small-section wire mill 350/250.
This is a modern universal highly automated mill for the bars (Ø10-30 mm) and wire rods (Ø5.5-12 mm) production in coils from various steel grades and titanium alloys.
The equipment of the new mill includes:
• section of a continuous train of horizontal and vertical stands 350 for the bars production,
• section of a continuous train of horizontal and vertical stands 250 for wire rods production,
• wire rod coiling section,
• energy sources systems, electric drives and automated process control systems,
“In the past NKMZ mainly carried out the modernization and reconstruction of mills of this type, manufacturing separate equipment for them, but for this project we have manufactured the entire mill, – says Dmitry Morozko, chief designer of the design department of NKMZ rolling mill equipment production division. – It is very important that for the 350/250 small-section wire mill, the Novokramatorsk employees, together with the engineering and equipment production, carry out a complete supply including rolling technology and software product. It should also be noted that at this mill we have provided the rolling of a fairly wide range of steel grades and alloys. Among them are carbon, structural, alloyed, corrosion-resistant, heat-resistant, oxidation-resistant, high-speed steels, as well as titanium alloys. Since they all require different values of force and rolling temperature, as well as different reduction (degree of metal deformation), then, as a rule, they are not rolled on the same mill. And the Novokramatorsk employees have created a universal mill with such capability. At the same time, our mill also differs from the mills of this type, which are operated by metallurgists today, by a high level of automation”.
