Alloys cored wire is a special form of alloy materials used for steelmaking and casting, the most used are ferro calcium CaFe cored wire and silicon calcium CaSi cored wire. It’s a kind of cored wire made of various specific alloy elements powder, physically mixed in a certain proportion, and then tightly wrapped with thin iron sheet.
Alloys cored wire main types: silicon calcium CaSi cored wire, pure calcium Ca cored wire, ferro silicon FeSi cored wire, ferro calcium CaFe cored wire, graphite (carbon) powder cored wire, calcium aluminum CaAl cored wire, silicon barium calcium BaCaSi cored wire, silicon barium aluminum BaSiAl cored wire, silicon aluminum barium calcium CaSiBaAl cored wire, ferro titanium FeTi cored wire, ferro manganese FeMn cored wire, rare earth ferro silicon magnesium FeSiMg cored wire, silicon carbide SiC cored wire, etc.
It helps adjust and control the content of easily oxidized elements and trace elements, and can greatly increase the alloy yield, reduce smelting costs, shorten smelting time, and accurately control the composition. It can purify molten steel and partly change the properties and forms of inclusions, improve the quality of molten steel and improve the casting state.There are two kinds of cored wires: Internally drawn cored wire and external cored wire. The mechanical equipment required for injection is simple and reliable, and occupies less area. Especially, the internally drawn type cored wire is more suitable for use in narrow and small places.
The cored wire is made of strip-shaped steel strip wrapped with alloy powder. In the smelting industry, the quality of molten steel is improved by feeding the molten steel into the cored wire.
Application: spheroidizing wire/inoculation wire/spheroidizing cored wire/casting steelmaking
Packing method: horizontal and vertical, the cable can be divided into internal tap and external type.
The cored wire is made of strip-shaped steel strip wrapped with alloy powder. According to the difference of alloy powder, it can be divided into: pure calcium cored wire, silicon calcium cored wire, silicon manganese calcium wire, silicon calcium barium wire, barium aluminum wire, aluminum calcium wire, calcium iron wire and so on.
In the melting industry, the quality of molten steel is improved by feeding the molten steel into the cored wire.
The cored wire can more effectively add smelting materials into molten steel or molten iron in the process of steelmaking or casting, effectively avoiding the reaction with air and slag, and improving the absorption rate of smelting materials.
Widely used as a deoxidizer, desulfurizer, and alloy additive, it can change the shape of molten steel inclusions and effectively improve the quality of steelmaking and casting products.
Coil Weight: 600kg±100kg, can be produced according to user requirements.
Appearance quality of core-spun wire: firm covering, no seams, no broken lines, uniform core material composition, high filling rate.
Packing: steel strap tight + waterproof plastic film + iron cover
Cable packaging: Horizontal and vertical two types of cable arrangement, divided into two types of packaging: internal tap type and external type.
Used as a unique form of deoxidizer, nodulizer or inoculant for steelmaking and casting.
Alloys cored wire is beneficial to adjust and control the content of easily oxidizable elements and trace elements, reduce smelting cost, shorten smelting time, and accurately control the content of ingredients.
Alloys cored wire can purify molten steel and partially change the nature and shape of inclusions, and improve the quality and casting state of molten steel.
Use the cored wire to process the molten steel, the alloy elements react smoothly in the molten steel, which can avoid secondary oxidation. After the reaction, the floating rate of the inclusions is fast, and the purification treatment effect is uniform.
The use of cored wire in steelmaking or casting can avoid bringing gas into molten steel.
The equipment for adding alloys cored wire is simple and reliable, with a small footprint, suitable for use in narrow workshops.
Cored wire is a composite material of any length wrapped with a cold-rolled mild-carbon steel strip after crushing various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) into certain particle sizes.
Cored wire technology is an external refining method developed on the basis of injection metallurgy technology in the 1980s. Cored wire is suitable for steel making and casting.
When used in steel making, it can purify the form of steel inclusions, improve the castability of molten steel, improve the performance of steel, significantly increase the yield of alloys, reduce alloy consumption, and reduce steelmaking costs, with significant economic benefits.
Calcium iron cored wire:
Calcium iron cored wire is a method of deoxidizing molten steel in steelmaking, suitable for steelmaking enterprises. Calcium iron cored wire is a core material composed of a mixture of 30-35% metal calcium particles and iron powder. The strip steel is wrapped to make calcium iron cored wire.
Advantages of calcium-iron cored wire: It is suitable for refining molten steel, can remove residual oxygen and inclusions in molten steel, has good fluidity of molten steel, and can reduce refining costs.
High calcium cored wire:
Using high-calcium cored wire for calcium treatment in the production of low-carbon and low-silicon steel can reduce the temperature drop by 2.6°C on average, reduce the silicon increase by 0.001%, shorten the wire feeding time by 1 minute, and increase the yield by 2.29 times compared with the iron-calcium wire.
The feeding amount of iron-calcium wire is 3 times that of high-calcium wire. If it is converted into the same calcium content for comparison, the feeding of iron-calcium wire is 2.45 times that of high-calcium wire.
High-calcium cored wire is used to process molten steel, and the level of inclusions in the steel is equivalent to that of fed iron-calcium wire, which can meet product requirements.
Calcium silicon cored wire:
The main raw material for the production of CaSi Cored Wire is Calcium Silicon alloy. The crushed calcium silicon powder is used as the core material, and the outer skin is cold-rolled steel strip. It is pressed by a professional crimping machine to make the silicon-calcium cored wire. In the process, the steel sheath needs to be tightly packed to make the core material fill evenly and without leakage.
Carbon cored wire:
Carbon cored wire is used for the purpose of increasing carbon in steelmaking, and is used for fine-tuning the carbon content of molten steel, which is beneficial to the control of carbon content in molten steel and can reduce production costs.
Carbon wire features:
The yield of carbon is more than 90%, and it is stable.
Reduce the production cost, which is lower than the cost of the currently used toner cored wire.
The product storage time is extended.
Alloy cored wire is suitable for deoxidation and desulfurization in steelmaking. It can improve the performance of steel, improve the plasticity, impact toughness and fluidity of molten steel. It also has the characteristics of directly entering molten steel for melting and uniform distribution tion.
