TOYO DENKA cored wires are wire-shape linear additives developed for molten steel in the steel manufacture process with metallic calcium, calcium alloys and other additives tightly covered by a thin steel plate. The wire injection method is a molten steel processing technique that allows additional components to be added stably with a high yield by adding cored wire to the depths of molten steel with a simple dedicated supply device.
This is a technique to add components stably with a high yield by adding cored wire to the depths of molten metal.
The magnesium wire method is a molten metal processing method to stably manufacture ductile cast iron.
It is possible to add components stably with a high yield by adding cored wire to the depths of molten metal with a simple dedicated supply device (wire feeder).
In addition, this is a system with a great deal of flexibility in terms of dealing with fluctuations in the quantity of molten metal, controlling the target quality and automating facilities.
