As we know, open tapping is a risky activity that may result in accidents in the lower parts of the copper smelter and ferrometal smelting, it is important to use safety or security materials. Open tapping in copper refining is generally performed using SC Lances (black pipes) but the issue is that if low-quality black pipes is used, there can be a possibility of oil on the surface of the steel pipe, which may easily catch fire. Hence, SC Lances is utilized for opening tap, which is somewhat less expensive but runs the possibility of oxygen leaking from welds, in order to decrease expenses in the ferrometal refining process.
In this content, we are going to discuss about the high-quality SC lance pipe, which helps to prevent hazards and also improves efficiency in the copper smelter and ferroalloy smelter.
Role of SC Lance in copper and ferroalloy smelters

Copper Smelter and Ferroalloy Smelter
Copper Smelter: Copper smelting plants separate elemental copper from copper concentrates over various sulfide oxidizing procedures. Primary copper smelting is the procedure of using pyrometallurgical techniques to refine copper sulfide ore concentrate from mined ore to create anode-grade copper.
Ferroalloy Smelter: Ferroalloys can be produced either by using metal thermic reduction with other metals or by combined carbon with a suitable smelting process. More often, ferroalloys are generated by carbothermic processes, involving the reduction of oxides with carbon (as coke) in the presence of iron. Adding certain elements to molten iron results in the creation of certain ferroalloys. Many ferroalloys may also be produced using direct reduction techniques.
SC Lance: Structure and Uses
The SC Lance is a mild steel pipe that produces a high temperature of over 3,000°C by burning itself and melts down solidified steel and slag on equipment.
Uses of SC Lance pipes:
- Removal of slag on the wall of the ingot case.
- Removing pig iron at the iron notch of a blast furnace.
- To remove slag in the ladle.
- Removal of steel-slag mixture at slag notch and iron notch of a blast furnace.
SC Lance: Advantages
・Welding: The SC Lance pipe is a high-quality mild steel pipe made from selected raw materials and welded for using high-frequency welding machines, and rechecked for welding leaks using electromagnetic inspection equipment, enabling us to provide reliable, high-quality mild steel pipes.
Surface with no oil: Tap holes opening are free of oil, grease, and other contaminants on the surface which bring safety during the operating process.
・Connections: The SC Lance is carefully designed, and the pipes are connected to minimize air leakage by various types of connection.
Conclusion:
The SC Lance pipes are used for tap hole opening, and hence there are various SC Lances available in the market which are somewhat less costly but it is also recommended to use high quality SC Lances to avoid any kind of hazards or accidents. Therefore, we always give assurance for our pipe’s quality, and it will always be our sincere request to give a try to our products once so that the customers can itself get a clear idea about the quality of our products.
