Abstract

The invention discloses a high-strength and high-wear-resistant cast steel reel formed by processing a cast steel material. The cast steel comprises the following components in percentage by weight: 0.60-0.85% of C, 6.0-8.0% of Mn, 0.8-1.2% of Si, 4.5-5.5% of Cr, 0.8-1.2% of Mo, 0.3-0.5% of Cu, 1.0-1.2% of Ni, 0.15-0.25% of Ti, 0.20-0.40% of V, 0.030-0.040% of RE, 0.020-0.030% of Mg, less than 0.02% of S, less than 0.03% of P and the balance of Fe and unavoidable impurities. The high-strength and high-wear-resistant cast steel reel has relatively high strength and wear resistance and can be suitable for large or superlarge engineering equipment. The invention also discloses a preparation method of the cast steel reel.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a cast steel reel with high strength and high wear resistance and a preparation method thereof. Background technique [0002] The reel is one of the key components of large-scale lifting equipment, rotary drilling and hoisting reducer. Since the load-bearing wire rope is directly wound on the reel, the reel directly bears the lifting load. The safe operation of rotary drilling and winch reducer has a vital impact. As the development of modern engineering tends to be large-scale, the application of large-scale or super-large lifting equipment, drilling equipment and hoisting reducers in the construction machinery industry is becoming more and more extensive, and the lifting weight and lift are greatly increased. For example: the hoisting weight of super-large hoisting equipment has reached several thousand tons; the lift of super-large hoist has reached hundreds of ...
