In billet furnaces, the discharge roller head plays a crucial role, as it needs to withstand extremely high temperatures and harsh working environments. Therefore, the selection of the appropriate heat-resistant steel material is essential to ensure the long-term stable operation of the discharge roller head. Among the many heat-resistant steel materials, ZG4CR28Ni48W5 stands out for its excellent performance and becomes an ideal choice for billet heating furnace discharge roller heads.
ZG4CR28Ni48W5 is a high-alloy heat-resistant steel with excellent high-temperature oxidation resistance and high-temperature strength. Alloying elements such as chromium, nickel and tungsten in its composition give it excellent oxidation resistance and high temperature stability. This enables ZG4Cr28Ni48W5 to maintain high hardness and strength in high-temperature environments, so as to effectively resist adverse factors such as thermal stress, thermal fatigue and thermal creep.
In addition, ZG4CR28Ni48W5 also has excellent corrosion resistance and can maintain a long service life in harsh working environments. Its moderate thermal conductivity and coefficient of thermal expansion enable the roller head to maintain a relatively stable size and shape when the temperature of the furnace changes, thus ensuring the smooth discharge of the billet.
To sum up, ZG4CR28Ni48W5, as a high-alloy heat-resistant steel, has become an ideal material for billet heating furnace discharge roller head with its excellent high-temperature oxidation resistance, high-temperature strength and excellent corrosion resistance. In practical application, it can effectively improve the high temperature resistance and service life of the discharge roller head, and provide a strong guarantee for the stable operation of the billet heating furnace.
