Abstract

The invention discloses a ZG25MnSY6 casting material. The ZG25MnSY6 casting material consists of the following components by mass percent: 0.15-0.2% of C, 0.3-0.45% of Si, 0.8-1.1% of Mn, less than or equal to 0.01% of S, less than or equal to 0.015% of P, less than or equal to 0.06% of Al, 0.6-0.9% of Cr, 1-1.2% of Ni, 0.3-0.5% of Mo, 0.1-0.15% of V and the balance of Fe, 100% in total. The invention also discloses a method for preparing a casting by using the ZG25MnSY6 material. According to the casting material, a certain alloying element is reduced or increased, smelting is carried out in an electric-arc furnace and refining furnace, an alterant is added in the later refining stage and heat treatment is carried out, so that the metallographic structure of the casting is good, the mechanical property of the casting is greatly improved, the strength and toughness are enhanced, and the service time of the casting is prolonged.

Description

technical field [0001] The invention belongs to the technical field of casting materials, and relates to a ZG25MnSY6 casting material, and also relates to a method for preparing castings by using the ZG25MnSY6 material. Background technique [0002] With the development of casting technology, the performance requirements of castings are getting higher and higher, which requires castings to have better materials, good metallographic structure and higher mechanical properties, so as to ensure that the castings are wear-resistant and wear-resistant during use. Fatigue resistance, to ensure that the casting will not be deformed or broken during use. Especially in coal mines for underground coal mining, the safety of castings plays a vital role in the safety of operators' lives and the continuity of equipment operation. Contents of the invention [0003] The object of the present invention is to provide a ZG25MnSY6 casting material, which solves the problems that the existing ...
