摘要
在制备陶瓷内衬复合钢管时 ,在铝热剂中加入活性碳粉、合金粉末 ,使原来纯铁过渡层成为钢过渡层 ,硬度大幅度提高 ,从而使钢管抗压强度明显提高。
Activated carbon powder and alloy powder is added into the thermite at the time of preparing CLSP(ceramic-lined steel composite pipe).The hardness is improved greatly because the transition zone of pure iron is turned into that of steel.Thus the compression strength of steel pipe rises obviously.
