5. Iron aluminum ceramic protective tube

Iron based materials containing aluminum and cleverly adding A12O3 powder can produce iron aluminum ceramic (TLC) with special gold content. By making the iron aluminum ceramic alloy into a thermocouple (resistor) protective tube, it becomes the most critical component of the iron aluminum ceramic thermocouple (resistor) - the iron aluminum ceramic protective tube. According to the working temperature, wear condition, medium type, pressure equation, different series of iron aluminum ceramic protective tubes are made. There are currently six series: TLC, TLC1, TLC2, TLC3, TLC4, and TLC5.

TLC type: resistant to hydrochloric acid, nitric acid, sulfuric acid, sodium hydroxide, and potassium hydroxide solutions. The working temperature is divided into two types: 350 ° C and 750 ° C.

TLC1 type: resistant to oxidation, sulfurization, and zinc steam corrosion, with high wear resistance, good heat and earthquake resistance, working temperature of 1100 ° C. After actual use, it has a service life of 4 months in zinc concentrate boiling furnaces, 12 months in pyrite boiling furnaces, 6 months in boiling furnaces and circulating fluidized bed boiler halls, and 6-8 months in ball mills and fan mills inlet and outlet.

TLC2 type: Operating temperature of 1250 ° C, with lower wear resistance than TLC1 type. Compared with ceramic tubes, it has far superior technical indicators such as thermal shock resistance, high temperature thermal strength, and working pressure (16MPa), making it particularly suitable for thermocouple protection tubes with a scale of S at 1250 ° C.

TLC3 type: Improved from TLC2 type, it not only has the characteristics of TLC2 type, but also has a special improvement in wear resistance. Under the same working conditions, it can increase the service life by twice. The working temperature is 1300 ° C.

TLC4 type: derived from TLC1 type, in addition to possessing the characteristics of TLC1 type, it has a special improvement in wear resistance, far higher than TLC1 type. Under the same working conditions, it can increase the service life by three times, with a working temperature of 1100 ° C. Through practical use, the service life of the protective tube used for temperature measurement at the inlet and outlet of the ball mill can reach 36 months.
