陶瓷內襯鋼管的研究

An Investigation on Ceramic Lined Steel Pipe

  • 摘要: 采用SHS-離心法制備陶瓷內襯鋼管時,離心力對Fe2O3和Al的燃燒過程及其產物的相分離和組織有重要影響,陶瓷內襯鋼管具有良好的機械性能和耐蝕性,計算表明,復合鋼管中,陶瓷層受壓應力,金屬管受張應力,這種殘余應力分布使復合管具有良好的抗機械沖擊和抗熱沖擊性.

     

    Abstract: Ceramic lined steel pipe was produced by centrifugal-SHS process. Centrigugal force effects on the combustion process, the phase separation and microstructure of SHS products. Mechanical properties and corrosion resistance of the ceramic lined steel pipe are good enough for practical purposes. The calculation of residual stress shows that ceramic layer is compressed by the outer metal pipe and outer metal pipe is in tension. This type of distribution of residual stress gives high resistance against thermal and mechanical shock.
