Advantages of Metal Seamless Calcium Wire

1. High calcium recovery rate

Compared with cored wire, solid wire has higher strength, density, and higher calcium content. It can feed calcium deeper into the molten steel and stay below the critical depth for a longer time, thereby achieving a higher calcium recovery rate. In practical use, the yield of solid calcium wire is higher than that of cored wire, and seamless metal calcium wire is higher than that of stitched wire. A certain factory uses 1.5mm seamless metal calcium wire, and the yield of SPHC steel grade is stable at over 38%.

2. Stable calcium addition in molten steel

The core materials of calcium iron wire and silicon calcium wire are calcium containing powders, which are prone to uneven and hollow core materials. The core material of solid pure calcium wire is high-density pure calcium core rod, which contains higher, more uniform, and more stable calcium per unit length, ensuring a more stable calcium treatment effect.

3. More suitable for pure steel production

Solid core pure calcium wire is a high-density pure calcium core rod, which is easy to detect in quality. The smaller surface area of the core wire is less prone to oxidation and loss of activity, allowing it to have a longer shelf life and reduce the amount of calcium oxide inclusions that contaminate the steel liquid; The calcium treatment process of solid core pure calcium wire will not introduce other oxides present in the powder cored wire and contaminate the steel liquid (such as iron oxide in calcium iron wire), and solid core pure calcium wire can further reduce the consumption of calcium per ton of steel and reduce steel pollution compared to traditional powder filled cored wire.

4. Reduce homework intensity to ensure smooth production

Calcium iron wire and silicon calcium wire are powder filled, with many uneven and hollow core materials. During the wire feeding process, wire breakage and jamming often occur, which has a certain impact on steelmaking production. Solid core pure calcium wire is a high-density solid core pure calcium rod wrapped in a thick steel shell. The wire quality is relatively hard, and it does not slip or run off during wire feeding, making the operation very smooth. In addition, the length of a single roll of solid core pure calcium wire is about twice that of calcium iron wire, and the amount used is less. The number of heats for a single roll of solid core pure calcium wire is four times that of calcium iron wire. Therefore, using solid pure calcium wire not only makes the feeding operation very smooth, but also significantly reduces the number of threading times and significantly reduces the workload of workers.
