Our Calorized lance pipe lasts 3 to 10 times* longer than mild steel lance. It is used for steel melting by blowing oxygen, carbon, lime, coke, iron ore and/or other additives.
Our calorized lance has been used since 1955 in over 70 countries and over 150 plants worldwide.
We are the forerunner in lancing technology and innovation where our R&D team is constantly inventing and further improving the lancing solution.

Our Daiwa Ca Lance also has a thin refractory on the interior surface that shields the steel from direct contact with oxygen stream.
On the exterior surface, it has a thick refractory coating that effectively protects the steel from heat attack.
Daiwa Lance has a homogeneous calorized layer both inside and out.
Curing the calorization process, aluminum diffuses into mild steel when heated up to 1,000C and forms heat resistant aluminum-iron alloy (Calorized Layer) over the surface of mild steel.
Both sample were exposed to about 1,270 °C for 50hrs.
We maintain strict quality control from raw materials to finished products. Our quality control team follows stringent protocols to ensure the safest lancing solution
The calorized layer and three-layer refractory coating ensure minimum lance pipe consumption, reducing costs and enhancing efficiency
