Wear-resisting coupling is a kind of common measuring instruments, are widely used in metallurgy, chemical industry, cement plants, power plants, etc. Wear resistance even at high temperatures and abrasion resistant environment plays a major role, the material of wear-resisting accidentally is varied and the characteristics of each type of material are different. Wear-resisting I accidentally high temperature alloy wear-resistant material 1 features, wear-resisting with special heat-resistant and wear-resistant alloy materials as temperature measuring external protecting tube and wear-resisting head, inner core body, the erosion of fly ash particles can not only has high corrosion resistance, long-term between 0 ~ 1200 ℃ temperature measurement, high temperature is used in metallurgical industry, wear-resisting environment ideal temperature sensor. Material: k1320 heat-resistant wear-resistant alloy temperature: 0 ~ 1200 ℃, high temperature metal alloys can be between 0 ~ 1200 ℃ temperature measurement for a long time, high temperature is used in metallurgical industry, wear-resisting material: environment ideal temperature sensor 3 yc52 or gh3030 heat-resistant wear-resistant alloy temperature: 0 ~ 1200 ℃, metal ceramic wear-resistant material components: sic using temperature: 0 ~ 1600 ℃ 4, hot blast stove is special wear-resisting specially suitable for hot blast stove temperature measurement. Material composition: sic using temperature: 0 ~ 1600 ℃, wear-resisting aluminium porcelain protect GuanTieJi containing aluminum and iron skillfully join a12o3 powders, namely system of iron and aluminum porcelain ( tlc) Special gold, iron and aluminum alloy porcelain made thermocouple ( Resistance) Protecting tube, become iron aluminum ceramic thermocouple (namely Resistance) - key parts Iron and aluminum ceramic protection tube.
