Abstract

The invention discloses a production process of a high-performance ceramic-lined composite steel pipe, and relates to the field of steel pipes. The production process comprises the following steps: adding 2, 4-diaminotoluene into a three-neck flask, adding dried pyromellitic dianhydride to obtain a product B, uniformly mixing SiO2 and B4C, adding a silane coupling agent, carrying out ultrasonic dispersion to obtain a product C, and adding the product C into the product B to obtain an additive A. The problems that an existing ceramic steel material cannot meet the high-temperature-resistant requirement, cracks are likely to be generated in the impact and vibration process, raw materials are likely to be agglomerated, and the dispersity is poor are solved. When the ceramic steel pipe is impacted, SiO2 dispersed in a matrix can absorb impact energy of microcracks in the matrix and prevent the cracks from expanding, so that the mechanical property of a system is enhanced, B203 in a molten state can flow to the cracks of a ceramic interface to inhibit crack diffusion, and the ceramic interface is denser, therefore, the ceramic steel pipe is resistant to high temperature and not prone to cracks.

Description

technical field [0001] The invention relates to the field of steel pipes, in particular to a production process for high-performance ceramic-lined composite steel pipes. Background technique [0002] Metal matrix composite material is a high-tech new engineering material with high specific stiffness, specific strength, excellent high temperature performance, low thermal expansion coefficient, good wear resistance and friction reduction, the most representative is ceramic steel Materials are more and more used in our lives. Because ceramic steel materials have many advantages of ceramics and steel, they are favored by users. Ceramic steel pipes are composite pipes that combine ceramics and metals. Ceramics Steel pipe has excellent wear resistance and corrosion resistance; [0003] The existing ceramic steel materials cannot meet the requirements of high temperature resistance, and are prone to cracks in the process of impact and vibration, resulting in damage to the ceramic ...
