山东球墨铸铁井盖深受欢迎的原因!

来源:http://www.kpp647.com添加时间:2019-09-21 15:19:31

我们也不难发现,有很多有很多井盖现在都选择了山东球墨铸铁井盖,那么这种井盖如此深受欢迎到底是因为什么呢?是因为山东球墨铸铁井盖有如下几点特色:

It's not difficult to find that many well covers are now chosen by Shandong ductile iron well covers, so what is the reason why such well covers are so popular? It is because Shandong Ductile Iron Well Cover has the following characteristics:

1.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。

1. 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. Its service life is twice that of grey iron pipe and five times that of ordinary steel pipe.

2.塑性好。延伸率≥7%,与高碳钢材相近,而灰铁材料延伸率为零。

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

3.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。

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

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

4. Due to the microstructures of spherical graphite in nodular cast iron, nodular cast iron is better than cast steel in reducing vibration ability, so it is more conducive to reducing stress. An important reason for choosing ductile iron is that the cost of ductile iron is lower than that of cast steel. The low cost of nodular cast iron makes this material more popular and more efficient. It also reduces the processing cost of nodular cast iron.

5。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。

5。 The strength of ductile iron is comparable to that of cast steel。 Ductile iron has higher yield strength, its yield strength is lower than 40k, while the yield strength of cast steel is only 36k。 In most municipal applications, such as water, brine and steam, the corrosion resistance and oxidation resistance of nodular cast iron are higher than that of cast steel。
