COMPANY PROFILE
Cored wire is a relatively new product. It began to be used no earlier than
twenty years ago. During the cored wire manufacturing process, adequate
tools first form a steel strip into a channel. Then the filling device fills it with
filler. The channel filled with filler is formed so that it gets a turn-up, which is
then closed. Thus, a pipe is made from a steel strip. Other tools calibrate this
pipe and wind the coil. The filled pipe or its profile has been manufactured.
Due to the English terms (cored wire), it is called “polna / strženska žica” in
Slovene. The cored wire is manufactured on special state-of-the-art automated
production lines. Thanks to them, the only tasks the workers need to do are:
preparing the lines, monitoring and exercising control over production, packing
and storing of new products.
Cored wire is designed for liquid metal treatment in steel industry, foundries
and in other metallurgical production. The type of the filler, with which a cold
rolled steel strip is filled up, primarily depends on its further use. The most
widely spread filler for manufacturing the cored wire is silico calcium. In
addition, many other alloys, metals, non-metals and the most varied mixtures
of these materials are used as fillers.
The cored wire production in Slovenia commenced in 1989, when the cored
wire works was established within the framework of the company called
Tovarna dušika Ruše. In 1996, the Filum Company Ltd took over the cored
wire works at the location of Tovarna dušika Ruše In 1999, we started cored
wire production by using our own manufacturing equipment and a special
procedure of manufacture, which was developed and patented within the
framework of our company Wire d.o.o. In 2005 our company moved into new
business and production premises, located in the Limbuš business park in
Maribor.

TRANSPORT
STORAGE
According to the CEE criteria, the cored
wire does not refer to the class of
hazardous substances for transport.
Cored wire should be stored in a dry
place, protected against damp and
atmospheric influences. Make sure
that the cored wire does not come into
contact with open flames and acids.
