摘要
根据硅砖的损坏机理,研究开发了陶瓷喷涂层,通过对涂层后硅砖性能的测试可知,硅砖涂层后渗碳深度由涂层前的15mm降低到涂层后的0.5～3mm。涂层后硅砖的磨损失重量由涂层前的0.43g减少到涂层后的0.023～0.076g。涂层后硅砖的热震稳定性大大提高了。涂层前硅砖1～2次就出现裂纹,涂层后硅砖达到15～30次才出现裂纹。
Flame sprayed ceramic coatings on the wall of coke oven are characterized before and after melting according to the damage mechanics of silica bricks.The attempt has been made to investigate thermal shock resistant,carbon deposit resistant,wear resistant of the coated and melted samples.The results show that the carbon deposit depth of coated samples is 0.5 ～ 3mm,but the carbon deposit depth of uncoated samples is 15mm.The wear resistance of the coated samples are better than that of the uncoated samples.The lost mass of coated sample is 0.023 ～ 0.076g,but the lost mass of uncoated sample is 0.43g.The thermal shock resistance cycles of the coating samples are 15 ～ 30 times,but uncoated samples are only 1 ～ 2 times.The main reason is that he coating substrate interface shows no gaps or cracks and it blunt the micro-cracks in the substrate.
