Our products

Product category: Nodularizing additions for spheroidal graphite cast iron

NODULARISERS

The name Nodulariser is used as a term for FeSiMg and FeNiMg alloys. These alloys are based on ferrosilicon or ferronickel, later alloyed with addition of magnesium, calcium and rare earth elements within very tight tolerances and very specific proportions.

The primary purpose of the Nodulariser is to intake the magnesium into melted cast iron.

Magnesium causes the spheroidization process, the graphite is extracted in the melt in a shape of small balls or nodulas (therefore the name “nodulariser”).

INOCULANTS

Inoculants are high-quality complex alloys, whose main task is the entry of suitable heterogeneous nucleation sites - crystallization centers in the molten metal. The term Inoculant by itself shows, that the process name is inoculation, extremely small additions of modifiers (inoculants) in the melt on one side, and on the other side big influence on the size, shape and distribution of extracted carbon in grey cast iron. To the base alloy, which is ferrosilicon, elements such as zirconium, manganese, barium, aluminum, strontium, bismuth and others are added.

CORED WIRES

Melt treatment technology using a cored wire is an automated system process controlled by software, where the FeSiMg alloy or inoculants are added to the melt as a filler in the wire.

About us

Company details

Company TDR Legure was established in February 2007 with the privatization and restructuring process of the previous company TDR Metalurgija in Ruse. TDR Legure is the successor to the so-called complex alloys program, which was once developed in TDR Metalurgija and has constantly been being improved for 30 years.

Today the primary production program still consists of the aforementioned complex alloys, which are used in different types of foundries for the production of high-quality cast iron, such as parts of breaking systems for the automotive industry, pipes for the distribution of drinking water or parts of wind turbines.

These alloys are called “nodulatorji in cepiva” or in English "Nodularisers and Inoculants" and in German »Vorlegierungen und Impfmitteln."

In general the company produces alloys with the technological upgrade of standard ferrosilicon. This means products with a higher level of added value.
