Comparison Of Machinery Casting Part With Stainless Steel Forgings



Comparison of Machinery Casting Part with stainless steel forgings

We are not familiar with the Machinery Casting Part. The application of Machinery Casting Part has a long history. In ancient times, people used Machinery Casting parts to make coin offerings, weapons, tools and some living things. In modern times, however, Machinery Casting parts are mainly used for machine parts or for machine parts. In mechanical products, the proportion of Machinery Casting parts is increasing, and the amount of Machinery is increasing year by year. The shape and variety of the Machinery Casting Part are constantly changing. Machinery Casting Part has gradually become an indispensable Part of our daily life, and the use of Machinery Casting Part can be seen in various kinds of doors, door locks, water pipes and so on.
Machinery Casting Part has excellent mechanical and physical properties, it can have a variety of different strength, toughness and hardness with comprehensive performance, also can have one or more special performance, such as wear resistance, high temperature and low temperature resistance, corrosion resistance, etc.
Machinery Casting Part weight and size range is very wide, only a few grams of weight lightest and the heaviest can reach 400 tons, the most thin wall thickness of only 0.5 mm, the thickness can be more than 1 m, length can be made of a few millimeters to several meters, can satisfy the use requirement of different industrial sectors.
Comparison between Machinery Casting Part and stainless steel forgings:
1. Machinery Casting parts with good abrasion resistance and elimination function, because the graphite cast iron is helpful to lubrication and oil reservoir, so the wearability. Similarly, as a result of the existence of graphite, elimination of grey cast iron is superior to the steel.
2. Machinery Casting Part process performance is good, because the grey cast iron carbon content is high, close to the eutectic composition, low melting point, good liquidity, small shrinkage rate, thus suitable for complex or thin wall Casting structure Machinery Casting Part. In addition, due to graphite is easy to form a chip breaker when machining, so the grey cast iron can be cutting machining is superior to the steel.
3. Stainless steel can improve its organizational structure and mechanical properties after forging. Casting organization after forging method of thermal deformation due to the deformation and recrystallization of stainless steel, make the original bulky dendrite and columnar grain to grain is fine and uniform axial recrystallization organization, make the ingot in the original segregation, porosity, porosity, slag compaction and welded, such as its organization become more closely, plasticity and mechanical properties of the metal.
4. Mechanical performance of Machinery Casting Part is lower than that of forging mechanical properties of the same material. However, forging processing can guarantee the continuity of metal fibre, the forging of fibrous tissue and forging appearance is consistent, can guarantee the parts with good mechanical properties and long service life with precision die forging, cold extrusion, extrusion temperature and other process in the production of forgings, are Machinery Casting Part is incomparable.
Whether Machinery Casting Part or stainless steel forgings, is an indispensable Part of in the production of Machinery, in mechanical production, depending on the product performance, choose the corresponding Machinery Casting Part or forgings, only give full play to the Machinery Casting Part or the role of forgings, can have perfect mechanical products.
However, China's casting production technology is high and equipment is limited to a few backbone enterprises, and the overall technical level of the industry is backward. The shape of the mold is still made by hand or simple machine. The socialization, specialization and commercialization gap of the production supply of the original auxiliary materials can not meet the needs of new technological development in the aspects of variety quality. The process design is based on personal experience, computer control and auxiliary process cae technology is used less; Poor basic conditions of casting technical equipment; The production process has a high proportion of manual operation, and the field workers have low technical quality. Only a few large automobile, internal combustion engine group foundry adopt advanced modelling core technology, most foundry enterprise still USES earthquake pressure moulding machine even hand modelling is given priority to. Low pressure casting can only produce non - iron parts; The technical stability of epc technology is limited to the production of Machinery Casting parts, such as exhaust pipe and shell, and low productivity, low level of accuracy and surface roughness of Machinery Casting Part; Although a relatively complete standard system of casting industry has been built, most enterprises have passive standards, and some enterprises have a waste rate of up to 30%.
