OOO NPP Technology Produces New Grade for PAO Tulachermet
15 April 2019
A new grade of cored wire, DM1, has been developed by OOO NPP Technology for desulphurizing purposes as ordered by PAO Tulachermet.
To ensure high results and reproducibility of the process of melt treatment, NPP's technologists have preliminarily developed the required filler material to be encapsulated in metal sheaths and subsequently used for cast iron modification and inoculation. They took into account all the peculiarities of Tulachermet's manufacturing processes. The molten metal from which pig iron was further produced was treated in a 70-tonne ladle.
The DM1 cored wire used for test purposes have shown high results including consistent quality of the product and high level of reproducibility. The DM1 cored wire is currently being mass produced.
