關于球墨鑄鐵井蓋的知識你了解多少?

發布日期:2018-03-20 作者:貴州鑄造 點擊:

球墨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。處理鑄件的常用涂料就是防銹瀝青漆了,當然球墨鑄鐵井蓋的表面也是經過噴涂防銹瀝青漆處理的。球墨鑄鐵井蓋有一個優點,就是由于球墨鑄鐵強度高、韌性好,使得球墨鑄井蓋要比同類型的灰口鑄鐵井蓋輕30%左右,貴州鑄造告訴大家市面上所說的鑄鐵井蓋指的就是球墨鑄鐵井蓋。

The cover of spheroidal graphite cast iron is mainly made of spheroidal graphite cast iron. The quality of this kind of well cover is involved in the problem of the rate of spheroidization. The commonly used coatings for castings are anticorrosive asphalt lacquer, and of course the surface of the ductile iron cover is also treated by spraying antirust bitumen lacquer. The advantage of ductile iron well covers is that the strength of ductile iron covers is about 30% lighter than that of the same type of gray iron covers because of the high ductility and toughness of ductile iron. Guizhou foundry tells you that the cast iron manhole covers on the market refer to the ductile iron manhole covers.

特點

Characteristic

韌性好:沖擊值與中碳鋼材詳盡,是灰鐵材料的10倍以上。

Good toughness and impact value: 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: water spray corrosion test, ninety days of corrosion is only 1/40 of steel pipe, is 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。

Good plasticity: elongation rate greater 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。

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

鑄鐵井蓋廣泛用于市政道路,高速公路,通信,電力,自來水,小區,學校等各種園區。

Cast iron shaft covers are widely used in municipal roads, expressway, communications, electricity, tap water, residential areas, schools and other parks.

鑄鐵井蓋一般分圓形和方形,鑄鐵井蓋規格尺寸:重型400KN,普型250KN,輕型125KN,方型:500*500  600*600  700*700 450*750等  圓型:600 700 800 900 1000等, 每種規格的重量分很多種,導致承重有所不同。

Cast iron manhole covers generally round and square, cast iron manhole cover size: heavy 400KN, general 250KN, 125KN light, 500*500 600*600 700*700 450*750: a square round type: 6007008009001000, the weight of each specification is divided into many kinds, resulting in different bearing.
