Excavator bucket manufactured from temperature-changing-resisting high-strength alloy steel

Abstract

The invention relates to the technical field of mechanical manufacturing, in particular to an excavator bucket manufactured from temperature-changing-resisting high-strength alloy steel. The alloy steel used for the bucket is prepared from, by mass, 0.10-0.16% of C, 0.24-0.26% of Si, 0.6-0.8% of Al, 0.11-0.14% of Mo, 0.14-0.18% of Cr, 0.03-0.09% of Ni, 0.34-0.37% of Cu, 0.04-0.06% of V, 0.005% orless of P, 0.008% or less of S, 0.03-0.08% of microelements and the balance Fe and inevitable impurities, wherein the microelements contain Ce, Sm, Dy and Y with the mass ratio being 3:1:1:2. The alloy steel is manufactured through the steps of smelting, refining, heat insulation, rolling, quenching, hardening and tempering, aging and the like, and the steel is machined through a lathe and weldedto form the bucket, and the surface of the bucket is subjected to nanometer enhancement treatment. The temperature changing resistance of the metal materials of the bucket is high, the prepared bucketis high in mechanical strength and good in wear resistance, and a manufactured excavator is wide in working temperature range and quite excellent in performance.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an excavator bucket made of temperature-resistant high-strength alloy steel. Background technique [0002] A bucket is a structure installed on an excavator or loader for excavating or containing bulk goods. This structure is the main functional part of the excavator and loader. Therefore, the quality and performance of the excavator bucket are required to be very good. [0003] The performance of the bucket is mainly the impact resistance of the block, the tensile performance and the wear resistance and corrosion resistance. For excavator buckets using conventional high-strength steel, these indicators can basically meet the requirements. However, the working temperature of ordinary excavators is within the normal temperature. For the work in high temperature and extremely cold environments, special excavators are required. The mechanical parts and materials of...

Problems solved by technology

However, the working temperature of ordinary excavators is within the normal temperature. For the work in high temperature and extremely cold environments, special excavators are required. The mechanical parts and materials of this excavator have been adapted to the working environment. The adaptability of the excavator to the extreme temperature environment has been improved, but the metal material of the current bucket has relatively poor performance in dealing with high temperature and extreme cold environments with large temperature changes. The large temperature change environment will affect the performance of the bucket and reduce the bucket service life
