Daiwa SC Lance is a type of consumable oxygen lance pipe manufactured from mild steel with a hollow structure that allows stable oxygen flow during operation.
Unlike conventional gas transportation pipes, a self-consuming lance pipe is designed to directly participate in the thermal reaction process. When oxygen passes through the pipe and contacts the target material, the pipe tip gradually consumes during operation while generating high-temperature heat.
The main characteristics of Daiwa SC Lance include:
With these characteristics, Daiwa SC Lance is applied in various oxygen lancing operations within steelmaking and metallurgical facilities.
A consumable oxygen lance pipe operates based on the principle of supplying oxygen through the internal hollow section of the pipe to create a high-temperature oxidation reaction. The basic process includes:
In practical applications, the flame temperature can exceed 3,000°C, making it suitable for operations such as tap hole opening, slag removal, and metal deposit cleaning.
Daiwa SC Lance uses mild steel material with a structure designed for high-temperature oxygen applications. The hollow pipe design helps:
During high oxygen applications, welding quality is an important factor related to operational safety. A high frequency welded oxygen lance uses high-frequency welding technology to:
The welded seam of Daiwa SC Lance is inspected through Eddy Current Test (ECT) to support quality control before delivery.
In environments using high-concentration oxygen, oil and grease residues on the surface may increase combustion risks. Therefore, an oil-free oxygen lance pipe and grease-free oxygen lance pipe are important requirements for many metallurgical applications.
The surface treatment of Daiwa SC Lance is designed to:
One of the common applications of Daiwa SC Lance is opening tap holes in steelmaking operations. A tap hole opening oxygen lance is used for:
During steel production, slag and metal deposits may accumulate inside equipment and processing areas. A slag removal oxygen lance is used for:
A steel mill oxygen lance is commonly used in:
In addition, the product can be used for furnace maintenance and cleaning tasks through a furnace cleaning lance pipe.
For steel manufacturers, selecting a lance pipe is not only about heat generation capability but also about ensuring operator safety during usage. Important safety factors include:
A welding seam that does not meet requirements may affect pipe integrity during oxygen operation. Important factors include:
The welding quality of Daiwa SC Lance is controlled through high-frequency welding and ECT inspection.
Oxygen lance pipes require proper surface treatment to remove oil and grease residues. A clean surface condition is one of the important safety considerations for Daiwa SC Lance, especially when used in oxygen-rich environments.
The wall thickness of a lance pipe affects:
Selecting suitable OD/ID dimensions and thickness helps ensure that the lance pipe matches actual working conditions.
For metallurgical applications, product quality control plays an important role in ensuring stable operation and safety during use. Daiwa SC Lance is developed with a focus on:
The quality management system includes internationally recognized certifications such as:
These certifications support quality control throughout the production process, from raw material inspection, manufacturing, welding control, surface treatment, to final product inspection.
When selecting an oxygen lance pipe for metallurgical operations, industrial users usually consider several important factors:
Daiwa SC Lance focuses on these key factors through the following advantages:
Choosing the correct lance pipe depends on actual working conditions and operational requirements. Important factors include:
The outside diameter (OD) and inside diameter (ID) should be selected based on:
For limited working areas, smaller size options may be suitable.
Wall thickness influences:
A suitable thickness selection helps reduce the possibility of deformation during furnace-side applications.
Daiwa SC Lance provides different connection options, including:
The appropriate connection type can improve handling efficiency and help reduce the risk of oxygen leakage during operation.
Daiwa SC Lance is a self-consuming oxygen lance pipe designed for high-temperature metallurgical applications, including tap hole opening, slag removal, furnace cleaning, and oxygen cutting.
With mild steel construction, clean surface treatment, high-frequency welded seam quality, and ECT inspection, Daiwa SC Lance supports safer and more stable oxygen lancing operations in steel mills, foundries, and smelting plants.
