Abstract

The invention discloses a processing technique for a crane cable pulley. The processing technique comprises the following steps: Si) slowly heating a stainless steel casting to Ac1 above 20-50 DEG C and maintaining for 10-15min; and Sii) cooling at the rate of 1-5 DEG C / min. The stainless steel casting contains less than or equal to 0.02% of C, less than or equal to 0.75% of Si, less than or equal to 0.05% of Mn, less than or equal to 0.01% of S, less than or equal to 0.02% of P, 21.00-23.00% of Cr, 8.00-9.50% of Ni, 0.30-0.45% of Cu, less than or equal to 0.03% of N, less than or equal to 0.04% of Ti and the balance of Fe and inevitable impurities, wherein 2C is less than or equal to Ti. A preparation method for the stainless steel casting comprises the following steps: carrying out cold rolling on the raw materials and then performing solution treatment, wherein the temperature for solution treatment is 1050-1075 DEG C and the solution treatment time is from 5min to 15min. The processing technique has an effect of reducing the rusting possibility of the crane cable pulley.

Description

technical field [0001] The invention relates to crane equipment, in particular to a processing technology for a crane cable block. Background technique [0002] The cables on the crane are generally carried and driven by cable pulleys for walking. The cable pulley is exposed and is eroded by rain all the year round. The bearings of the cable pulley rollers are prone to rust, so that the cable pulley rollers cannot rotate on the track but rub hard. In the case of strong pulling and pulling, the cable pulley is pulled down or The case where the cable falls off. In order to solve this problem in the prior art, generally adopt the cable block that stainless steel is material, to reduce the possibility of getting rusty. [0003] The application publication number is CN103131961A, and the Chinese patent application publication date is June 5, 2013 discloses a corrosion-resistant stainless steel plate and its preparation method and application, which consists of the following com...
