Monoblock cast all-purpose horizontal high-chromium cast iron collar and preparation method

Abstract

The invention discloses a monoblock cast all-purpose horizontal high-chromium cast iron collar. The monoblock cast all-purpose horizontal high-chromium cast iron collar is composed of two mixing components, one component comprises, by mass, 1.70-2.10% of C, 0.40-1.00% of Si, 0.70-1.20% of Mn, 0.20-1.30% of Ni, 10.00-20.00% of Cr, 0.50-1.50% of Mo, less than or equal to 0.03% of S, less than or equal to 0.03% of P and the balance Fe and inevitable impurities; and the other mixing component comprises, by mass, 0.70-1.20% of C, 1.30-1.90% of Si, 0.50-0.80% of Mn, less than or equal to 0.50% of Ni, less than or equal to 0.50% of Cr, less than or equal to 0.15% of Mo, less than or equal to 0.03% of S, less than or equal to 0.03% of P and the balance Fe and inevitable impurities. Meanwhile, the preparation method of the high-chromium cast iron collar is further disclosed. The produced high-chromium cast iron collar is high in hardness and good in abrasion resistance, and meanwhile the high-chromium cast iron collar has long service life.

Description

technical field [0001] The invention belongs to the field of iron and steel forging, and in particular relates to an integrally cast universal horizontal high-chromium cast iron roll ring and a preparation method thereof. Background technique [0002] With the serious overcapacity of the steel industry, major steel mills pay more attention to energy saving and consumption reduction, especially for large H-shaped steel roll rings. At present, the products with large diameter and large specifications are mainly imported products, especially the large diameter and large specifications of more than 1400mm. Can't make a good product yet. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a universal horizontal high chromium cast iron roll ring for integral casting to address the deficiencies of the prior art. [0004] The invention also discloses a preparation method of the integral cast universal level high chromium...
