At INTECH, the production of cored wire for out-of-furnace processing began in 2016. Today, the company is a leading manufacturer and supplier of cored wire in Ukraine, produces its various types, and remains true to its main principle – offering the market only the highest quality products.
The cored wire is a thin-walled steel tube with powdered fillers required for metal smelting. The wire is used in out-of-furnace processing to adjust the quality features of steel and cast iron.
Currently, there are various types of this product. The main differences between the existing metallurgical cored wires are the filler composition, diameter, profile and thickness of the shell, the size and orientation of the coils, and the presence of a metal frame.
The company can also produce cored wire with other content and type of fillers after the reconciliation of product features.
The filler composition corresponds to the purpose of the wire in the technological process. The most common filler materials are silicon calcium, metal calcium, steel or cast iron shot, graphite, ferrotitanium, ferrovanadium, rare-earth elements, and other types.
Filler type | Filler chemical composition | Filler density, g/m | Application | |
Silicocalcium | SiCa 30 | Ca: 30-32%, Si: 58-62% | 205(+30,-12) | Active complex deoxidizer. Effective degasser. Reduces non-metallic inclusions, improves fluidity and castability of steel. |
SiCa 40 | Ca: 38-41%, Si: 50-52% | 210(±15) | ||
Ferrocalcium | CaFe 30 | Ca: 28-31% + metal shot | 260(±20) | Active complex deoxidizer. Effective degasser. Reduces non-metallic inclusions, improves fluidity and castability of steel. Used in melts with low silicon content. |
CaFe 40 | Ca: 38-41% + metal shot | 215(±10) | ||
Ferrotitanium | FeTi 70 | Ti: 65-75%, Si: max 1%, C: max 0,4%, Al: max 5% | 350(±25) | For alloying, it increases the heat resistance of steel, improves adhesion (weldability). |
Magnesium staurolite | MgSt | Mg: 24-26% + staurolite concentrate 74-76%(Al₂O₃=40%) | 112(±7) | Desulfurization and inoculation of cast iron. Helps to reduce the sulfur content in cast iron. |
Ferromanganese with magnesium | MgFeMn | Mg: 14-18% + FeMn: 82-86% | 180(±20) | Desulfurization and inoculation of cast iron. Helps to reduce the sulfur content in cast iron. |
Ferrosilicon with magnesium | MgFeSi | Mg: 9-12% + FeSi: 88-91% | 250(±20) | To increase Si% of cast irons, sulfur globulation. |
Carbon wire | Сarbonaceous material | C: min 95%, S: max 0,7%, Calx: max 4%, Humidity: max 0,9% | 150(±15) | It is used to fine-tune the carbon content in a narrow range. |
Graphite | C: min 98%, S: max 0,1%, Calx: max 0,6% | 150(±15) |
*By agreement with the customer, other components can be used, along with other filler ratios, and filling density in 1 running meter.
The cored wire is a steel tube with powdered fillers. The base of the product is a steel strip that is cold-formed into a circle. The formed gutter is filled with powder, and after that, the edges of the tape are closed in a “lock”. The resulting wire is wound into coils of various sizes according to the customer’s requirements.
This product is used in almost all steel and iron foundries, regardless of the capacity of the casting ladles. The process of introducing cored wire is carried out in metal finishing installations at the final stages of fusion.
Cored wire for complex processing of liquid steel helps to provide accuracy of dosed input of components, ensures their high and stable assimilation, uniform distribution over the metal area, and, thus, is the basis for precision processing of liquid metal. It includes:
The use of cored wire for out-of-furnace metallurgical melts processing makes it possible to reduce the consumption of materials for adjusting the chemical composition of the metal, alloying and modifying steel and cast iron, to increase the efficiency of their assimilation by the melt due to the reduction of waste, and also to increase the environmental safety of manufacturing.
For many years, INTECH has been demonstrating high-quality indicators in metallurgical products manufacturing, gaining the trust of domestic and foreign customers.
