PhosphatePhosphate is an antioxidantAntioxidant commonly used for impregnating treatment of low-temperature and medium-temperature carbon sleeves for continuous annealingContinuous annealing furnace in siliconSilicon steelsteelSteel production. The microstructureMicrostructure, topography and composition of the buildups embedded on and adhered to the surface of the carbon sleeveCarbon sleeve were investigated by SEMSEM and EDX. The water resistance performance of carbon sleeveCarbon sleeve dipping with phosphatePhosphate was tested by soaking method. It is found that the buildups contain high phosphorus which mainly comes from phosphatePhosphate antioxidants in the carbon sleeveCarbon sleeve. A large quantity of white substances seeped out to the surface of carbon sleeveCarbon sleeve after soaking for 24 h. The water resistance of carbon sleeveCarbon sleeve treated with phosphatePhosphateantioxidantAntioxidant was poor. In terms of the resistance to buildups formation and water, phosphatePhosphate is not a good antioxidantAntioxidant for carbon sleeveCarbon sleeve in continuous annealingContinuous annealing furnace for silicon steelSteel production.
