球墨铸铁井盖的特点

来源:http://www.kpp647.com添加时间:2019-05-10 16:58:15

在现在的城市中,球墨铸铁井盖非常的常见,下面山东球墨铸铁井盖厂家就给大家普及一下球墨铸铁井盖的特点,希望对大家有所帮助!

Nodular cast iron manhole covers are very common in modern cities。 Now Shandong Ductile cast iron manhole covers manufacturer will popularize the characteristics of nodular cast iron manhole covers, hoping to help everyone!

1、韧性好。冲击值与中碳钢材详尽,是灰铁材料的10倍以上。

1。 Good toughness。 The impact value of medium carbon steel is more than 10 times that of gray iron。

2、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。

2. Strong corrosion resistance. In the spray corrosion test, the corrosion amount in 90 days is only 1/40 of steel pipe and 1/10 of gray iron pipe. The service life is twice as long as that of gray iron pipe and five times as long as that of ordinary steel pipe.

3、塑性好。延伸率≥7/100,与高碳钢材相近,而灰铁材料延伸率为零。

3. Good plasticity. The elongation (> 7/100) is similar to that of high carbon steel, while the elongation of gray iron is zero.

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

4. High strength. Tensile strength (> 420 MPa) and yield strength (> 300 MPa) are the same as low carbon steel and three times as that of gray iron.

球墨铸铁的强度和铸钢的强度是可比的,球墨铸铁具有更高的屈服强度,其屈服强度更低为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,球墨铸铁的耐腐蚀性和抗氧化性都超过铸钢,主要应用领域:市政道路,高速公路,通信,电力,自来水,小区,学校等各种园区。

The strength of ductile iron is comparable to that of cast steel. Ductile iron has higher yield strength, the lowest yield strength is 40k, while the yield strength of cast steel is only 36k. In most municipal applications, such as water, brine, steam, etc., the corrosion resistance and oxidation resistance of ductile iron are higher than that of cast steel. The main application areas are municipal roads, highways, communications, power, tap water, residential areas, schools and other parks.

5、较好的防盗与安全性能:球墨铸铁井盖篦子的抗拉强度及耐压性能与钢相似,因此又名铸钢。相比传统灰口铸铁其延伸率大大提高,具有良好的韧性,不易破坏,具有比普通铸铁井盖较好的防盗性能,整体性能更大大优于普通铸铁井盖。

5。 Better anti-theft and safety performance: Ductile iron well cover grate has similar tensile strength and pressure resistance to steel, so it is also known as cast steel。 Compared with the traditional grey cast iron, its elongation is greatly improved, its toughness is good, and it is not easy to be damaged。 It has better anti-theft performance than the ordinary cast iron well cover, and its overall performance is greater than that of the ordinary cast iron well cover。

6、无噪音:由于采用防止噪音的专利构造,井盖过车时无声音,不再扰民。

6。 Noise-free: Because of the patented structure to prevent noise, the cover of the well is silent when passing the car and will not disturb the people any more。
