sg cast ductile iron casting parts manufacturers suppliers
2022-05-10 17:40:47
We know that iron can be traced back to the frontier of history, and blacksmiths cast iron casting in technical ways. The combination of various precision iron casting parts has created countless miracles for mankind. Still, we need to pay attention to its longevity.
In this article, you will get tips to improve the service life of cast iron platforms and cast iron castings, as well as an understanding of ductile iron castings. These will come from one of the world's professional sg iron casting manufacturers-Minghe.
How do improve the service life of cast iron castings and cast iron platforms?
Needless to say, you need to know the quality standard of cast iron platforms, that is, the working surface is free of casting defects such as cracks, pores, and blisters. This is not allowed, so when using it, we need to handle the workpiece lightly, let alone move the rougher workpiece.
Master the working conditions of the parts
First, master the specific working conditions of the parts and the type of wear that plays a major role, and then it is possible to select materials reasonably. When selecting materials, considering the specific situation in your country, in addition to resource conditions, you should also consider the economic conditions of the people and the affordability of the factory.
Let's take wear-resistant cast iron as an example. If you want to have enough wear resistance and a favorable price, you can choose from several items listed, such as low-alloy white cast iron, medium manganese ductile iron, ordinary white cast iron, etc. Some users will choose less expensive
materials, although this will require frequent replacement of parts.
Reasonably determine the lower and upper limits of hardness
The hardness of cast iron plates and castings is inversely proportional to the toughness and wear resistance of the material, so if the hardness is increased, catastrophic failure may result. Plus, under certain circumstances, microscopic cracks will occur in materials that are too hard. At this time, increasing the hardness will reduce the wear resistance of the material. Thus, the lower and upper limits of the hardness should be reasonably determined.
Ensure good internal quality
An important factor affecting the service life of wear-resistant cast iron platforms and cast iron castings is the internal quality of cast iron castings. Most of the anti-wear cast irons are white cast irons with different compositions, so defects such as internal shrinkage holes, shrinkage porosity, pores, inclusions, and even cracks are prone to occur grinding ability. Therefore, it is a very important link to use the correct process method to ensure internal quality.
In the above content, we mentioned that ductile iron has a high-cost performance. So is there any benefit to using ductile iron casting?
Benefits of ductile iron castings
Ductile iron casting is a kind of spheroidal graphite, which greatly improves the mechanical properties of cast iron, especially in terms of plasticity and toughness, so it is stronger than carbon steel.
It has the characteristics of good size shape and repeatability and fine casting, which can replace fine casting to a certain extent.
Castings with high surface finish
Eliminates sand cores and cores
Simplify the molding process
The use of no binder effectively eliminates various disadvantages caused by moisture, additives, and binders
Simplified sand handling system, almost all molding sand is reused.
It is easier to shake out the sand, which greatly reduces the workload and labor intensity of the falling sand.
Castings have no flash and burrs, reducing the cleaning and grinding workload by more than 50%.
Well-shaped casting risers can be set in the ideal position
Above all are its advantages, which can be for your purchase reference. If you are looking for cost-effective cast irons, we recommend ductile irons. If you decide to choose, comparing ductile iron casting suppliers is a wise way, and Minghe can offer Ductile Iron (SG) Casting, we are one of the professional sg cast ductile iron casting parts manufacturers supplier in the world. Any interests, welcome to contact us.
