1. Adaptability

High calcium seamless cored wire is mainly used for iron and steel smelting. It can fully penetrate to the bottom of molten steel to enhance fluidity and stability of molten steel, decompose and separate the residues in the molten steel to make the molten steel clear and meet the requirement to purify the molten steel. At present, it is the best material for calcium processing in domestic iron and steel smelting.

2. Processing Standard

In the process of manufacturing high calcium seamless cored wire is from raw material, heating, processing to fine packaging. It cannot be rated as high calcium seamless cored wire unless its usage rate of calcium is secured to reach 45% to 50% and above.

3. Analysis of Similar Calcium Processing Materials

① The calcium usage rate of silicon calcium cored wire is 7% to 8%;

② The calcium usage of ferro-calcium cored wire is 10% to 12%;

③ The calcium usage of pure calcium cored wire is 18% to 25%;

④ The calcium usage of high calcium particle seamless cored wire is 20% to 26%;

⑤ The calcium usage of high calcium seamless 1.0 is 26% to 30%;

⑥ The calcium usage of high calcium seamless 1.5 is 45% to 50%.

4. Development Trend

In order to achieve national brand strategy as soon as possible, steel is a leading industry of China. Whether steel quality can be improved is the largest challenge that the steel works are facing. Only with the best raw materials, the most advanced equipment and the most intelligent technicians, the best steel in the world can be smelt out!
