Performance Characteristics of Wear Resistant Ceramic for Induced Draft Fan
According to the different working temperature, the use of wear-resistant ceramic fan is divided into three areas, namely:
Wear-resistant fan impeller use a wide range of use mainly based on the operating temperature of the fan to determine, not affected by the impact of wear media.
Its resistance to grain erosion and wear performance at least ordinary tungsten carbide surfacing, spray spray welding and alloy powder welding and other conventional treatment methods to improve more than 5 times higher than the matrix 16Mn steel more than 100 times; thickness of 1.5mm ceramic actually use
As the fan blade working surface composite ceramic layer hardness HRA ≥ 86 (toughened alumina composite material), local wear serious parts of the use of secondary sintered silicon nitride toughened ceramic or zirconia toughened alumina ceramic, up to HRA94 above,
