貴陽鑄鐵井蓋具有的特點你知道嗎?

1貴陽鑄鐵井蓋

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


貴陽鑄鐵井蓋主要由球墨鑄鐵打造出來的井蓋,這種井蓋質量的好壞就牽扯到了球化率的問題。處理鑄件的常用塗料就是防鏽瀝青漆了,當然貴陽鑄鐵井蓋的表麵也是經過噴塗防鏽瀝青漆處理的。貴陽鑄鐵井蓋有一個優點,就是由於貴陽鑄鐵強度高、韌性好,使得貴陽鑄井蓋要比同類型的灰口鑄鐵井蓋輕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.


貴陽鑄鐵井蓋的特點:

The features of Guiyang cast iron shaft cover:


韌性好。衝擊值與中碳鋼材詳盡,是灰鐵材料的10倍以上。

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


抗腐蝕性強。噴水腐蝕試驗,九十天的腐蝕量僅為鋼管的1/40,是灰鐵管的1/10。使用壽命是灰鐵管的2倍,是普通鋼管的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%,與高碳鋼材相近,而灰鐵材料延伸率為零。

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


強度高。抗拉強度ób≥420MPa,屈服強度ós≥300MPa,與低碳鋼材相同,是灰鐵材料的三倍。

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.


由於貴陽鑄鐵的球狀石墨微觀結構,在減弱振動能力方麵,貴陽鑄鐵優於鑄鋼,因此更加有利於降低應力。選擇貴陽鑄鐵的一個重要的原因在於貴陽鑄鐵比鑄鋼成本低。貴陽鑄鐵的低成本使得這種材料更加受歡迎,鑄造效率更高,也較少了球墨鑄鐵的機加工成本。

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.


貴陽鑄鐵的強度和鑄鋼的強度是可比的。貴陽鑄鐵具有更高的屈服強度,其屈服強度最低為40k,而鑄鋼的屈服強度隻有36k。在大部分市政應用領域,如:水、鹽水、蒸汽等,貴陽鑄鐵的耐腐蝕性和抗氧化性都超過鑄鋼。

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.
