What is? Eh? When we introduced the ductile iron manhole cover before, we also talked about its nature, performance and application. As a symbol of safety, we must do a good job in use and production to ensure the quality of its use. It is made of high-strength materials, so we can rest assured when using it. Now let's find out what is Hainan ductile iron manhole cover.
Hainan nodular cast iron manhole cover is one of the products of nodular cast iron. Nodular graphite is obtained from nodular cast iron through spheroidizing and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than carbon steel. Ductile iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is precisely based on its excellent performance that it has been successfully used to cast some parts with complex stress and high requirements for strength, toughness and wear resistance. Ductile iron has rapidly developed into a widely used cast iron material, which is second only to gray iron. The so-called "replacing steel with iron" mainly refers to nodular cast iron.
Nodular cast iron manhole covers are mainly made of nodular cast iron. The quality of such manhole covers is related to the spheroidization rate. The commonly used coating for processing castings is antirust asphalt paint, of course, its surface is also treated by spraying antirust asphalt paint. It has an advantage that because of its high strength and good toughness, it is about 30% lighter than the same type of gray cast iron manhole cover.
The reason why the ductile iron manhole cover is called ductile iron is of course determined by its own material, so when we use this product, we must first understand its performance and advantages, specific applications, which are the key issues, so I hope you can have a better understanding of today's introduction.
