The sample is taken from the edge, 1 / 2R and center of lzqt600-3 ductile iron profile. It is first
From the development and research trend of chemical heat treatment in atmosphere in recent years, it is still a hot
When the piston pump works under high hydraulic pressure, abrasive wear and adhesive wear are the main failure causes of
Nowadays, friction, lubrication and wear are the three most important research topics in tribology. Friction will cause wear, resulting in
The diffusion coefficient of nitrogen atom in α – Fe is larger than that of carbon atom. The main mechanism
Soft nitriding, also known as nitrocarburizing, is a process of infiltrating nitrogen into the surface of workpieces and also carbon
Carbon and nitrogen elements are infiltrated into the workpiece surface at the same time. The process is called carbonitriding. The
In the presence of active nitrogen atoms in the gas, liquid or solid as the medium, under a certain temperature
Carbon atoms are infiltrated into the surface of steel samples, and carburizing layer is formed on the surface of steel
In the hydraulic system, the most important function similar to the “heart” is the high-pressure plunger pump, which is also
As shown in the figure is the schematic diagram of the horizontal continuous casting cast iron profile production line. After
The production efficiency and yield of continuous casting billet can be improved by this process, the cost is lower than
The most important part of equipment manufacturing industry is hydraulic system, which plays an important role in various engineering fields.
With the development of computer hardware and simulation software and the maturity of various finite element software, the application of
The design takes the tractor split axle housing as the research object. The axle housing is made of zg40mn low
When the molten metal is poured into the mold, the volume shrinkage will occur during cooling and solidification. This shrinkage
The numerical simulation of temperature field is the basis of ProCAST software simulation, and also the core module. Through the
In the filling process, the flow of molten metal will have a great impact on the quality of the axle
ProCAST casting computer simulation process: firstly, Creo software was used to establish the three-dimensional numerical model of the casting system
The gating system is the channel to guide liquid metal into the mold cavity in sand mold. Its structure is
Numerical simulation is a method that uses the correspondence between different things to verify measures. Numerical simulation is irreversible. Casting
Casting process parameters mainly include dimensional tolerance, linear shrinkage, draft angle and other aspects. The determination of these process parameters
The linear shrinkage of the bridge shell has a great influence on the accuracy of the size of the bridge
Generally speaking, the higher the pouring temperature is, the better the fluidity of alloy liquid is, and the more favorable
For sand mold casting, in order to realize sand molding, mold taking, pouring riser setting and sand core installation, the
The pouring position usually refers to the position of the axle housing in the mold when pouring. The pouring position
For cast steel, the main raw materials include scrap steel, ferrosilicon, manganese iron and aluminum alloy deoxidizer, and the main
(1) Scrap steel is the main raw material for casting smelting. Two samples are randomly selected from each batch for
The structural types of axle housing can be roughly divided into three types: open type, integral type and combined type.
