Properties Of Materials For Forged-steel Roll

The materials used for forged-steel roll pass through the processes including smelting,forging and heat treatment,it is ensured that the working surface on roll barrel has the characteristics of uniform metallurgical structure,high hardness,high abrasive resistance and excellent failure-resistance ability,meanwhile the neck and core of roll has a certain strength and high ductility.As the forged-steel roll has the sole properties,it has the advantages not substituted by the cast…

Design of work Roll

The modern col-rolled joint unit has really realized high-speed and continuous endless bar rllingThe productivity of roll has increase greatly. The cold-olled products has developed in the direction ofhigh-precision, high-quality and multi model The quality of cold-rolled working roll shall affect directlythe surface quality of plate material, the qualifed rate and operating rate of mill Therefore, the quality ofcold-rolled working roll is very important. The basic…

Mold Crystallizer aluminum for continuous Casting machine-HZ

The cast roller core material used 42CrMo. Roller cover material use special material: 32Cr3Mo1V. We use scientific method to design various types of aluminum cast roll and the cast roller. Finished product own better quality and long service life. The Mold Crystallizers for casting rolling mill are of good heat, corrosion, wear-resistant properties, working at high temperature environment on average: 800 to 1200°C, which are used…
