The bearing box of the supporting roller on the transmission side of the hot rolling mill
Application scenarios of the support roller bearing box on the transmission side of the hot rolling mill
Core functions
Heavy load support: withstand rolling force (up to 3000-8000kN on one side) and transmit it to the frame.
Precise guidance: Ensure that the radial runout of the support roller is ≤ 0.03mm (guaranteeing a thickness tolerance of ± 0.1% for the strip steel).
Lubrication management: Integrated oil air lubrication system (pressure 0.2-0.5MPa), suitable for high-speed rolling (≤ 15m/s).
Typical compatible models
Four roll hot rolling mill: used for the production of carbon steel and stainless steel plates and strips (thickness 2-25mm).
Reversible roughing mill: capable of withstanding frequent reversing impact loads (rolling force fluctuations ± 20%).
