| Calorised Steel Pipe is continuously hot dip diffusion coated inner & outer with an aluminum coating according to the standard of GB/T*********1.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 *0 and *5 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 **0℃。 | ||
| 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. |
| Oxygen Lance Pipe,are small diameter pipes used with oxygen is an invaluable tool for the primary metals industry. It is used daily in almost all ferrous and non-ferrous primary production facilities.This small diameter pipe serves below purposes for these industries: | ||
| Oxygen lance tube for decarburize： | ||
| Carbon and other chemical constituents impart certain attributes or properties to a metal and these elements must therefore be carefully measured and controlled during the smelting process. Employed in blast furnaces, basic oxygen furnaces as well as induction and electric arc furnaces, oxygen lance tube is used for decarburize i.e. a process of pumping an oxygen rich mixture at high pressure through oxygen lance tube into the melt. The oxidizing effect burns off the excess carbon in the molten metal thus reducing the percentage of carbon to an acceptable level. | ||
| Oxygen lance tube are used for opening furnace tap holes: | ||
| When the desired steel composition and temperature has been reached, the furnace tap hole is opened through a combination of drilling and tapping using oxygen lances. Lances are coupled to a high pressure oxygen supply, the end of the lance is ignited and through careful and skillful manipulation, the tap hole clay which can be up to **0mm thick is effectively burnt away, facilitating the pouring of the molten metal for further processing. | ||
| Oxygen lance tube for cleaning ladle well blocks: | ||
| Ladle well blocks require cleaning once the casting process has been completed. Ladles are tipped to remove the slag. Oxygen lances are employed to clean both the upper and lower nozzles and if necessary, the bottom of the ladle is also cleaned with a lance tube if it contains impacted debris. | ||
| Oxygen lance tube are used for unclogging tundish nozzles： | ||
| Tundishes are receptacles used to temporarily store a batch (melt) of molten metal while it is moved through the production process. Unclogging nozzles with oxygen lance tube is a more cost effective option than replacing entire nozzle systems. | ||
| Oxygen lance tube are used for cutting skulls | ||
| Oxygen lances are used effectively to cut and clean skulls which are layers of slag and process metals that have solidified or frozen against the refractory material forming a layer of insulation which reduces heat losses and protects the furnace lining from erosion, chemical attacks and thermal shock. | ||
| Oxygen lance tube are used for cleaning up spillages | ||
| Oxygen lances are used to cut up solidified molten metal spillages into smaller pieces facilitating handling and thus aiding the re-smelting or disposal of the sometimes valuable spilt material. |
