贵阳铸铁井盖具有的特点你知道吗?

1贵阳铸铁井盖

Do you know the features of the ductile iron shaft cover?


贵阳铸铁井盖主要由球墨铸铁打造出来的井盖,这种井盖质量的好坏就牵扯到了球化率的问题。处理铸件的常用涂料就是防锈沥青漆了,当然贵阳铸铁井盖的表面也是经过喷涂防锈沥青漆处理的。贵阳铸铁井盖有一个优点,就是由于贵阳铸铁强度高、韧性好,使得贵阳铸井盖要比同类型的灰口铸铁井盖轻30%左右。

The cover of the Guiyang cast iron shaft is mainly made of spheroidal graphite cast iron. The quality of this kind of well cover involves the problem of the rate of spheroidization. The commonly used coatings for castings are anticorrosive asphalt lacquer. Of course, the surface of the Guiyang cast iron well cover is also treated by spraying antirust bitumen paint. The advantage of Guiyang cast iron manhole is that the cast iron covers of Guiyang are lighter than the same type gray iron covers by 30% because of the high strength and toughness of Guiyang cast iron.


贵阳铸铁井盖的特点:

The features of Guiyang cast iron shaft cover:


韧性好。冲击值与中碳钢材详尽,是灰铁材料的10倍以上。

Good toughness. The impact of value and medium carbon steel in detail, is more than 10 times the iron material.


抗腐蚀性强。喷水腐蚀试验,九十天的腐蚀量仅为钢管的1/40,是灰铁管的1/10。使用寿命是灰铁管的2倍,是普通钢管的5倍。

Strong corrosion resistance。 In the water jet corrosion test, the corrosion amount of ninety days is only 1/40 of the steel tube and the 1/10 of the ash iron pipe。 The service life is 2 times that of the gray iron pipe and 5 times that of the ordinary steel pipe。


塑性好。延伸率≥7%,与高碳钢材相近,而灰铁材料延伸率为零。

The plasticity is good. The elongation rate is more than 7%, similar to high carbon steel, and iron material extension rate is zero.


强度高。抗拉强度ób≥420MPa,屈服强度ós≥300MPa,与低碳钢材相同,是灰铁材料的三倍。

The strength is high. The tensile strength, yield strength, B = 420MPa, s = 300MPa, with the same low carbon steel, is three times the iron material.


由于贵阳铸铁的球状石墨微观结构,在减弱振动能力方面,贵阳铸铁优于铸钢,因此更加有利于降低应力。选择贵阳铸铁的一个重要的原因在于贵阳铸铁比铸钢成本低。贵阳铸铁的低成本使得这种材料更加受欢迎,铸造效率更高,也较少了球墨铸铁的机加工成本。

Because of the microstructure of the spheroidal graphite of Guiyang cast iron, the Guiyang cast iron is better than the cast steel in reducing the vibration capacity, so it is more beneficial to reduce the stress. One of the important reasons for the selection of Guiyang cast iron is that the cost of Guiyang cast iron is lower than the cost of cast steel. The low cost of Guiyang cast iron makes this material more popular, higher casting efficiency, and less machining cost of ductile iron.


贵阳铸铁的强度和铸钢的强度是可比的。贵阳铸铁具有更高的屈服强度,其屈服强度最低为40k,而铸钢的屈服强度只有36k。在大部分市政应用领域,如:水、盐水、蒸汽等,贵阳铸铁的耐腐蚀性和抗氧化性都超过铸钢。

The strength of the cast iron in Guiyang is comparable to the strength of the cast steel. The yield strength of Guiyang cast iron is higher, the yield strength is lowest 40K, and the yield strength of cast steel is only 36K. In most of the municipal applications, such as water, brine, steam, and so on, the corrosion resistance and oxidation resistance of Guiyang cast iron exceed the cast steel.
