According to the functional characteristics of bearings and the differences in the use of working conditions, after the selection of suitable bearing types, it is necessary to carry out routine inspection of bearings, including the specification and processing accuracy of bearings and assembly parts

Pearlite nodular cast iron rollers have high strength and toughness, can withstand high pressure and impact load, and are not easy to fracture or deformation, which ensures the stability of rolling. Pearlite nodular cast iron roll is suitable for roughing mill, which can meet the roughing requ

The HSS roll called by people at present is high carbon and HSS duplex roll. Namely the material of working layer is high carbon　and high-speed steel. The materials of core are spheroidal graphite cast iron, graphitic steel or forged steel etc. Two diferent kinds　of materials compounded by centrifug

ICDP rolling mill is a high-performance steel rolling mill, officially known as Indefinite Chill Double Poured Rolls, meaning "Infinite Cooling Double Poured Rolls". It is a composite material composed of a working layer with high surface hardness and strong wear resistance, and a cast iron layer with good central toughness, which is widely used in the steel metallurgy and non-ferrous metal processing industries.
