We supply all the types of oxygen lance pipes according to your requirement.
Oxygen Lance is a hollow electric welded tube used in various sizes from 1/8 INCHES to 2 INCHES inside diameter.
Oxygen Lance Pipe comes in a variety of end finishes. End caps are provided to prevent contamination. Oxygen Lancing is a reliable method for tapping heats or for other production operations.
Oxygen Lance Pipe is used to remove the carbon from molten metal. During the steelmaking process, a desired carbon content is attained by injecting oxygen into the molten metal. This process is used in blast furnaces, basic oxygen furnaces and also induction and electric furnaces
Lances are used for opening furnace tap holes, cleaning ladle well blocks, unclogging tundish nozzles, cutting ferrous materials, providing the steel or iron is hot enough to sustain burning, ie cutting skulls, spill clean-up, etc

Thermal lance also known as burning bar or thermic lance, made by hollow mild steel pipes filled with a number of iron wires, which is a powerful efficient cutting tool by high purity oxygen flow through the interior of the lance to create extraordinarily high temperature from 3,600 to 4,426�°C for cutting through just about anything. Thermal lance can be used whenever some ferrous and non-ferrous materials must be removed or cut into pieces, like sand casting riser cutting or ladle furnace tapping. When molten material is spilled, it can be allowed to solidify and then cleaned up with thermal lance. For coastal buildings, interior concrete sometimes breaks down to produce what is called concrete cancer, but thermal lance can be used to remove this degrading concrete so that replacement material can be packed in. These characteristics of the thermal lance make it a particularly efficient and cost-effective method of cutting steel and cast-iron materials too thick to be cut with a normal oxy-acetylene torch. In the case of thicker materials, during the operation, the lance tube will be consumed by the intense heat at the cut point and should be discarded once it becomes too short to be safely used.

Calorised Steel Pipe is continuously hot dip diffusion coated inner & outer with an aluminum coating according to the standard of GB/T18592-2001.The hot dip diffusion process, pioneered by Xingrui, provides a tight metallurgical bond between the steel and the coating,lance pipe lasts five to seven times longer than mid steel pipe in oxygen injection,also shorten the tap-time in the oxygen enrichment operation
In our calorising process, the diffusion layer formed is a mixture of iron and aluminides, dependent on the substrate material, with an aluminium content of between 30 and 45 wt. % at the surface. The percentage of aluminium gradually decreases through the diffusion zone to that of the substrate material.
This process results in a material with the strength of steel plus the corrosion protection of aluminum, and the synergistic heat protection of an aluminum alloy,high temperature resistance can reach to 600
In any calorising process, components are placed in a steel retort surrounded by a powder mixture containing aluminium, a halide and an inert diluent. The retort is then sealed, placed into a furnace and heated to an elevated temperature, held at temperature and then slowly cooled back to room temperature. After cooling the components are removed from the retorts and cleaned to remove any compound or residues.
In the process of steel manufacturing by open hearth or electric furnace, the consumption rate of lance pipes for oxygen injection sows rather high ratio owing to high temperature and severe oxidation. In general, steel pipes are used as lance pipes for oxygen injection. If mild steel pipes are treated by this process consumption rate of lance pipes will increase 6 - 7 times. It is necessary to make the pipe fireproof as a first step. Special treatment is then needed to protect the pipe from any falling-off or scaling-off by shock or by bending stress.
As a result of research conducted over many years, it was discovered that the most effectual method is to diffuse aluminium into the pipe's surface, so as to promote wear proof properties on steel pipe. That is to say, calorising is to be carried at, in and outside of the steel pipe to promote wear and fire proof properties of the pipe.
