Over the past two months, the Ukrainian manufacturer of seamless pipes Nizhnedneprovsk Pipe-Rolling Plant (Interpipe NTZ) has completed repairs of ring furnaces at rolling mills in two pipe shops at once - TPTs-3 and TsNGS.
The repairs of both objects were almost identical. In the furnaces, the masonry of the upper hearth was replaced for better and more uniform heating of the workpiece. As noted at the enterprise, this will improve the quality of rolled products and finished products in general. In addition, the centering devices of the piercing mill were restored at the furnace in TPTs-3, and the internal mechanisms and assemblies of the gear stand of Pilgerstan No. 1 were replaced at TsNGS.
All planned works were completed ahead of schedule. The cost of furnace repairs was over UAH 11 million.
