In our calorising process, the diffusion layer formed is a mixture of iron and aluminides.
Calorised Steel Pipe is continuously hot dip diffusion coated inner & outer with an aluminum coating according to the standard of GB/Tl8592-2001.The hot dip diffusion process, pio- neered by Xingrui, provides a tight metallurgical bond between the steel and the coat- ing,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, de- pendent on the substrate mater, 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 resis- tance can reach to 600°C .
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.
