Wear-resistant thermocouple protection GuanTieJi contain aluminum and iron and aluminum porcelain cleverly add a12o3 powder, iron and aluminum porcelain was made by the ( 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. According to working temperature, wear condition, the type of medium, pressure equation, made into different series of iron and aluminum ceramic protection tube, the existing series: TLC, tlc1, tlc2, tlc3, tlc4 and tlc5 six big series. TLC: resistance to hydrochloric acid, nitric acid, sulfuric acid, sodium hydroxide, potassium hydroxide solution. Working temperature can be divided into: 350 ° c and 750 ° c. Tlc1 type: resistance to oxidation, sulfide, resist the corrosion of zinc vapor, has high wear resistance, good thermal shock resistance and working temperature: 1100 ° c. Through actual use in zinc concentrate fluidized bed life 4 months, in pyrite, fluidized bed life 12 months in a fluidized bed and circulating fluidized bed boiler furnace service life of 6 months, in the import and export service life of 6 - ball mill, fan mill 8 months. Tlc2 type: working temperature of 1250 ° c, wear-resisting performance is lower than tlc1 type, compared with ceramic tube thermal shock resistance, high temperature hot strong sex, the working pressure, 16 mpa and other technical indicators, particularly applicable to 1250 ° c indexing number s of the thermocouple protection tube. Tlc3 type: modified by tlc2 type, tlc2 model characteristics, has improved especially in the wear resistance, much higher than tlc1 type, under the same conditions, can improve the life of two times. Working temperature of 1300 ° c. Tlc4 type: type tlc1 will then have it tlc1 model characteristics, has improved especially in the wear resistance, much higher than tlc1 type, under the same conditions, can improve the life of three times the working temperature of 1100 ° c. Through actual use, import and export temperature measurement in the ball mill with protecting tube life up to 36 months. Wear-resistant thermocouple temperature metal alloys with special heat-resistant and wear-resistant alloy material as the temperature measuring external protecting tube, inner core body, both have high corrosion resistant performance of particle erosion, and under the condition of high temperature on the inner core body can play a good protective effect. Can adopt the flanged or threaded connection, 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 resistance using protection of silicon carbide ceramic tube, high temperature can reach 1300 ℃, built-in or k s dividing core body, specially applicable to the cement preheater, working condition of circulating fluidized bed contour U. S. wear-resisting of temperature measurement. Material composition: sic using temperature: 0 ~ 1300 ℃ high temperature metal alloys 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, and under the condition of high temperature on the inner core body can play a good protective effect. Can adopt the flanged or threaded connection, between 0 ∽ 1200 ℃ temperature measurement for a long time, is applied to metallurgical industry is ideal in high temperature, wear-resistant environment temperature sensor. Material: k1320 heat-resistant wear-resistant alloy temperature: 0 ~ 1200 ℃ hot blast stove is special wear-resistant thermocouple protection tube, using new type of silicon carbide ceramic high temperature can reach 1300 ℃, for inner core s degree or high b dividing WenXin body, specially suitable for hot blast stove temperature measurement.
