A large number of furnace bottom rollers and radiation tubes in continuous heating furnaces and heat treatment furnaces in metallurgical plants are also made of high alloy heat-resistant steel centrifugal cast pipes. Commonly used grades include 0Cr18Ni9, 00Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 00Cr17Ni12Mo2, 3Cr24Ni7SiNRe, 0Cr23Ni13, 1Cr20Ni14, Cr25Ni20Si2, 00Cr10Ni20Mo6Cu6, 4Cr25Ni35NbW, 70CrMoVBRe, 4Cr28Ni48W5Si2, 3Cr26Ni4MnMoRe, etc.
In the cement industry, a large number of heat-resistant steel components such as 3Cr24Ni7SiNRe, 1Cr20Ni14, Cr25Ni20Si2, etc. are used in the preheating belt of wet cement kilns, the grate plate used in large cement inspection and cooling machines, and the material hopper used in cooling machines
