What is the influence of the five elements on casting
Stainless steel is cast steel with carbon as the main alloying element and a small amount of other elements. Carbon content is less than0.2%Is cast low-carbon steel, containing carbon0.2%——0.5%Is cast medium carbon steel with carbon content greater than0.5%Is cast high-carbon steel. With the increase of carbon content, the strength of cast carbon steel increases and the hardness improves. The cast carbon steel for coffee machine parts has high strength, plasticity and durability, and low cost. It is used in heavy machinery to make parts that accept heavy loads, such as rolling mill racks, hydraulic press bases, etc.; used in railway vehicles to make Parts that are subject to great force and impact, such as bolsters, side frames, wheels, and couplers.
Generally speaking, for medium and large castings, iron castings can be produced with resin hard sand molds and steel castings with water glass sand molds. Castings with the correct size and clean surface can be obtained, but the cost is high. Of course, the precision, surface cleanliness, material density, metallographic structure, and mechanical properties of the castings produced by sand precision casting manufacturers are very poor. When the performance requirements of the castings are higher, other casting methods should be used.
The service life of precision casting is very long because of its accuracy. If other parts need to be replaced due to a long history, the service life of precision casting is only a childhood if calculated according to the average life of a person.
Castings may not be subject to the metal material, limit size and weight of the tube bundle. Casting materials can be various kinds of pig iron, steel castings, aluminum alloy profiles, alloy copper, die-cast aluminum, titanium metal, zinc alloy materials and various non-alloy materials; castings can be as small as multiple, as large as hundreds of tons ;The wall thickness of the casting can be from0.5mmUp to one meter; the length of the casting can range from millimeters to ten meters.
Casting can produce blanks of various chaotic shapes, and is very suitable for the production of blanks with chaotic inner walls, such as various shells, engine blocks, leaves, centrifugal impellers, etc.
The shape and size of the casting can be very close to the part, which saves metal materials and saves comprehensive man-hours for drilling, production and processing.
The origin of the general application of castings is widely used, and the castings are low-cost.
