热熔稀土浸铝—冶金采矿
Hot-Dipped Rare Earth Aluminum -- Metallurgy and Mining


冶金工业多数在高温、高磨损及特定的腐蚀环境中作业,存在大量的高温和硫、氯的腐蚀,采矿业对竖井、设备、管道存在大量的吸氧腐蚀,电化学腐蚀及冲刷磨蚀,特别是煤矿和铁矿用本公司的浸铝技术,可以有效地解决以上问题。

方案一:在500℃以下的工况环境下,其管材、型材及金属制品,经浸铝后可直接使用,特别是动力系统的给排水、燃气、蒸汽等大多是管道输送。对于地下管网除存在土壤腐蚀外,还普遍存在杂散电流的腐蚀,造成地下管道腐蚀穿孔。用上浸铝技术后,可有效地解决腐蚀问题。

方案二:在500℃以上的工况环境下,其管材或钢制品在浸铝后要进行高温扩散热处理,使钢体表面的铝扩散到钢基体的金相格里,形成很好的铁铝合金。这不仅能起到耐高温腐蚀的作用,还具有很好的耐磨蚀作用。

多年来,我们为日本生产的熔镁锅,为多家钢厂生产的耐热换热器管束,为日本新日铁生产的熄焦床车,医院用垃圾焚烧炉等,都有很好的使用效果。


The metallurgical industry works in high temperature, high wear, high heat, sulfuric and chlorine corrosive environment. Whereas in the mining industry, there exists a lot of corrosive factors on the shaft well, equipment, piping, oxidation, electro-chemical corrosion and abrasion erosion elements. This is particularly true in the coal and iron ore operation. The use of the company's Hot-dipped aluminum technology, can effectively solve the above problems.

Option One: Under 500 ℃ environmental conditions, the piping, profiles and metal products, can be used directly after Hot-Dipped Aluminum with Rare Earth. This is specially critical in the power supply and drainage systems with gas, steam and mostly in the pipelines. In addition to the existence of underground pipe network confronted by soil erosion, but also the prevalence of stray current corrosion, resulting in the underground pipeline corrosion and perforation. After the Hot-Dipped Aluminum process, it can effectively solve corrosion problems.

Option Two: above 500 ℃ environmental conditions, the pipe or steel products after Hot-Dipping run through high-temperature heat diffusion treatment. This will diffuse aluminum on the surface of the steel micro-structure creating a good layer of Aluminum-Ferrous Alloy. This not only exhibit high-temperature Anti-corrosion nature, but also has good abrasive resistance.

Over the years, we have processed many Japanese Magnesium melting pots, steel-heat exchanger tubing, Nippon Steel Melting production beds, hospital waste incinerators’ structure, with excellent results.
