Introduction to alloy cored wire
The cored wire is made of strip-shaped steel strip wrapped with alloy powder. It is wound on a reel and produces a coil weight of 100-3000 kg. The diameter of the wire is 3-18mm.
The core wire is compact and the powder material is evenly mixed. The weight of the powder can be calculated by the unit length (meter).
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.
Cored wire 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.

Types of alloy 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.
(1) 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.
(2) 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.
(3) 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.
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.
The addition of calcium-silicon cored wire is mainly used for deoxidation, alloying and desulfurization operations in the smelting process.
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:
1. The yield of carbon is more than 90%, and it is stable.
2. Reduce the production cost, which is lower than the cost of the currently used toner cored wire.
3. 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.
Aluminum-calcium cored wire is an auxiliary material used in metallurgy and steel manufacturing. It is made of aluminum-calcium alloy as the inner core, and the outer shell is wrapped by metal or alloy wire.
Aluminum-calcium alloy is an alloy containing aluminum and calcium elements. The addition of aluminum-calcium cored wire is mainly used for deoxidation, alloying and desulfurization operations in the smelting process
The silicon, calcium and barium elements in the silicon-calcium-barium cored wire can react with the oxygen in the furnace to form oxides, thereby effectively removing the oxygen content in the furnace. This helps reduce porosity and inclusions in the steel, improving the purity and uniformity of the steel
The addition of silicon-calcium-barium cored wire can help adjust the chemical composition of the steel and change the properties of the steel, such as increasing strength, improving wear resistance and high temperature resistance, etc.
What projects can alloy cored wire provide services for?
The cored wire can be used as a deoxidizer, alloying agent and desulfurizer in the casting process. They are added to molten metals to improve the quality, mechanical properties and corrosion resistance of castings.
Reduce pores and inclusions: The deoxidizer in the cored wire can effectively remove oxides in molten metal, reduce the formation of pores and inclusions, and improve the compactness and intrinsic quality of castings.
Improve mechanical properties: By adding appropriate alloying agents, the microstructure and chemical composition of castings can be adjusted to improve mechanical properties such as hardness, strength, toughness and fatigue resistance.
Improve corrosion resistance: The addition of alloying agents can improve the corrosion resistance of castings, making them better in oxidation resistance, acid and alkali resistance or high temperature resistance under specific environmental conditions.
Cored wire is also used in specific steelmaking processes outside of traditional smelting methods. For example, they can be used in secondary refining processes such as ladle metallurgical furnaces (LMF) and vacuum degassers (VD/VOD). Alloy cored wire allows precise control of the addition of alloying elements and the removal of impurities during these refining stages.
The addition of alloying agent can reduce the pores and inclusions in the steel, and improve the purity and uniformity of the steel. Increase the strength, wear resistance, high temperature resistance and other characteristics of steel
