Beschreibung
Zusammenfassung:	The invention discloses a semi-high-speed steel cold rolling work roller high in accident resistance and a manufacturing method of the semi-high-speed steel cold rolling work roller and relates to the technical field of machining and heat treatment. The chemical components of materials of the semi-high-speed steel cold rolling work roller comprise, by weight percentage, 0.60-1.20% of C, 0.8-2.00% of Si, 0.20-1.00% of Mn, 4.50-10.00% of Cr, 1.0-4.00% of Mo, 0.20-2.00% of V, not larger than 0.025% of S, not larger than 0.025% of P and the balance Fe and inevitable impurities. According to the semi-high-speed steel cold rolling work roller high in accident resistance and the manufacturing method of the semi-high-speed steel cold rolling work roller, by designing the reasonable alloy components and the reasonable machining technology, the semi-high-speed steel cold rolling work roller is good in accident resistance, the service life of the cold rolling work roller can be substantially prolonged, and production efficiency is improved.
