Metallurgy and Heavy Industry
It is required to cope with harsh environments such as high-temperature dust and high-pressure water descaling. For example, the valves of blast furnace hot blast stoves need to withstand high temperatures of 1200℃ and isolate dusty flue gas; the high-pressure water descaling system for steel rolling needs to withstand high-frequency impact water hammer above 30MPa; and the high-temperature alkali solution in alumina production requires resistance to strong alkali scouring and anti-scarring.
