ADAMITE ROLLS PDF

Share to Adamite Roll Adamite rolls have the good abrasion resistance and the chemical composition contains various alloying elements. The carbon content of the alloy adamite roll is usually between 1. It has the feature of small hardness drop, good wear resistance, good toughness, significantly reduced consumption and the surface are made of the quality of section steel and beams is improved obviously. In addition, the semi-steel adamite roll is cast as a whole and there is no weak interface in compound casting roll, thus it has a better capacity, strength and toughness than cast iron roll. The rolls can be used as work roll, back-up roll and vertical roll for large-class and medium-class rough rolling mill and intermediate rolling mill of section steel, wire rod, rail beams, steel billet, hot rolling steel strip. Most of the semi-steel rolls are produced by the static integral casting method.

The rolls can be used as work roll, back-up roll and vertical roll for large-class and medium-class rough rolling mill and intermediate rolling mill of section steel, wire rod, rail beams, steel billet, hot rolling steel strip.

Most of the semi-steel rolls are produced by the static integral casting method. The centrifugal composite semi-steel back-up rolls are made of semi-steel material, the body and neck of the rolls are made of nodular cast iron, and they have been successfully used in hot-rolled strip steel finishing mill. The semi-steel roll ring is produced by composite centrifugal casting. The outer layer of the roll ring is high-carbon semi-steel.

The inner layer of the roll ring is graphite steel or ductile iron. Use a high-speed rotating centrifuge to make two different types of molten steel poured and cast. Adamite rolls must be subjected to high-temperature diffusion annealing. Generally, semi-steel rolls are required to control the total amount of non-metallic inclusions below 0. Application Work roll, back up roll and vertical roll for section steel mill, wire rod and bar rough rolling, medium rolling mill, large and medium section steel rolling mill, rail beams, steel billet mill, universal section steel mill; hot rolling steel and strip rough rolling mill.
