Abstract
The invention discloses a preparing method of a loader bucket plate, which comprises the following steps: (1) the bucket plate is formed by performing heat treatment on high nickel cast iron and high nickel nodular cast iron by adopting a two-step smelting method; (2) the surface of the high nickel nodular cast iron is subjected to surface treatment, oxide scale is treated by adopting a sand blasting or shot blasting method, and the preparing method has the characteristics of convenience in manufacture, good product quality and long service life.
Description
Technical field
The invention belongs to loader accessory technical field, relate to the preparation method of loading shovel plate.
Background technology
Loader is mainly used in the handling operation of material, and bucket configuration is more single, and the structure of scraper bowl directly governs the operating efficiency of loader, and the application life of scraper bowl is directly connected to the use cost of loader.Existing scraper bowl all adopts common iron structure.When scraper bowl is in the places such as mining site or building stones field during operation, because the quality of ore, rock is harder, during handling, the friction of scraper bowl and material is to loading shovel, especially the operator plate of scraper bowl and side cutting edge cause comparatively havoc, thus greatly reduce dependability and the life-span of loading shovel.At present, people adopt the operator plate existing common iron structure made and side cutting edge high-strength abrasion-proof steel to replace.But owing to loading and unloading frequently, after of long duration, loading shovel just can not insert in material preferably, makes the oil consumption of loader increase.
Summary of the invention
The present invention is intended to the defect overcoming prior art, provides a kind of preparation method of loading shovel plate, has easy to make, the feature of good product quality, long service life.
Object of the present invention carrys out specific implementation by the following technical programs:
A preparation method for loading shovel plate, comprises the steps, (1) scraper bowl plate is high nickel cast iron, and ductile Ni-resist cast iron heat treatment adopts two step smelting process process; (2) surfacing is carried out on ductile Ni-resist cast iron surface, adopts blasting method or ball blasting method to oxide skin process.
Further, two step smelting processes, metallic nickel and ferrosilicon are smelted into Ni-Si-Fe alloy by the first step makes its fusing point reduce, and when making second step melting, magnesium can remain on boiling point once; Second step melting obtains Ni-Mg-Si-Fe alloy.
Further, ball blasting method carries out shot-peening for using net belt type shot-blasting machine to oxidation sheet.
Compared with prior art, the present invention has following beneficial effect:
The present invention has easy to make, can effectively eliminate spheroidal graphite casting gas hole defect.Place the local shrinkage porosity defect of contraction cavity of internal densener and external chill solution foundry goods if desired.Add the application life of loading shovel.
Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
A preparation method for loading shovel plate, comprises the steps, (1) scraper bowl plate is high nickel cast iron, and ductile Ni-resist cast iron heat treatment adopts two step smelting process process; (2) surfacing and physical treatment are carried out in ductile Ni-resist cast iron surface, adopt blasting method or ball blasting method to oxide skin process, and wherein, ball blasting method carries out shot-peening for using net belt type shot-blasting machine to oxidation sheet.
Further, two step smelting processes, metallic nickel and ferrosilicon are smelted into Ni-Si-Fe alloy by the first step makes its fusing point reduce, and when making second step melting, magnesium can remain on boiling point once; Second step melting obtains Ni-Mg-Si-Fe alloy.
Last it is noted that the foregoing is only explanation embodiments of the present invention; be not limited to the present invention; for a person skilled in the art; within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
