采用ＳＨＳ铝热－重力分离法制备氧化铝陶瓷内衬复合钢管，研究了预热、保温、装料密度、添加剂等因素对所制备的内衬陶瓷复合管涂层厚度的影响，分析了陶瓷层的组织和性能。结果表明，通过预热、保温、控制装料密度和添加剂等可有效地提高熔体流动性，使陶瓷的凝固、结晶过程得到进一步控制，从而达到控制复合管内衬陶瓷层厚度的目的。
The effects of preheating, heat preservation, loading density, additives and other factors on the coating thickness of ceramic-lined composite tube were studied by SHS thermogravimetry and thermo-gravimetric separation method. The effects of ceramic layer Organization and performance. The results show that the solidification and crystallization of the ceramics can be further controlled by preheating, holding temperature, controlling the density of additives and other additives to effectively improve the fluidity of the melt so as to achieve the purpose of controlling the thickness of the ceramic layer lined by the composite pipe.
