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在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,也较少了球墨铸铁的机加工成本。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*氧化性都超过铸钢。

Due to the spheroidal graphite microstructure of nodular cast iron, nodular cast iron is better than cast steel in reducing vibration, so it is more conducive to reducing stress. An important reason for choosing nodular cast iron is that the cost of nodular cast iron is lower than that of cast steel. The low cost of nodular cast iron makes this material more popular, higher casting efficiency and less machining cost of nodular cast iron. The strength of nodular cast iron is comparable to that of cast steel. Nodular cast iron has higher yield strength, and its yield strength * is as low as 40K, while the yield strength of cast steel is only 36K. In most municipal applications, such as water, salt water, steam, etc., the corrosion resistance and oxidation resistance of nodular cast iron are higher than that of cast steel.

他的抗震和抗腐蚀性强。喷水腐蚀试验,九十天的腐蚀量仅为灰铸铁井盖的1/40,是灰球墨井盖的1/10。使用寿命是复合井盖和水泥井盖的2倍,河南球墨铸铁井盖是普通灰铁井盖的5倍。球墨铸铁井盖只有我们对球墨井盖进行合理的使用与耐心的维护,它的使用寿命才会延长的奥。

He is strong in earthquake resistance and corrosion resistance. In the water spray corrosion test, the corrosion amount in 90 days is only 1 / 40 of that of gray cast iron well cover and 1 / 10 of that of gray nodular graphite well cover. The service life of well cover made of Henan gray iron and cast iron is 5 times that of ordinary well cover. The service life of nodular cast iron manhole cover will be prolonged only if we use it reasonably and maintain it patiently.

(6)稀土镁球墨铸铁。在高强度低合金球墨铸铁方面,除了对铜、钼研究较多外,还对镍、铌等进行了研究。在利用**钒钛生铁制作钒钛合金球墨铸铁方面,中国国内一些单位进行了大量、系统的工作。中锰球墨铸铁虽然在性能上不够稳定,在系统研究与生产应用,取得了显着的经济效益。球墨井盖主要应用领域:市政道路,高速公路,通信,电力,自来水,小区,学校等各种园区。

(6) Rare earth magnesium nodular cast iron. In terms of high strength and low alloy nodular cast iron, in addition to copper and molybdenum, nickel and niobium were also studied. Some units in China have done a lot of systematic work in the production of vanadium titanium alloy nodular cast iron from * * vanadium titanium pig iron. Although the properties of medium manganese nodular cast iron are not stable enough, remarkable economic benefits have been obtained in systematic research and production application. Main application fields of nodular well covers: municipal roads, highways, communications, electric power, tap water, residential areas, schools and other parks.

球墨井盖能装饰城市道路。马路上的球墨井盖很多,铸铁井盖上面的花纹、字样都不一样,井盖的用途也不一样,下面为大家介绍一下这些井盖井底下面的世界1、排水工程井盖:于雨水、污水管线。2、给水工程井盖:应用于自来水、消防工程等。3、供热工程井盖:应用于热力臂线。4、供电工程井盖:应用于电力供应缆线、电信工程、电话、通信电缆管线。5、园林工程井盖:应用于配套综合管线。6、燃气工程井盖:应用于煤气工程、**气管线等。7、路灯工程井盖:应用于供电、照明、电缆管线。

Nodular well covers can decorate urban roads. There are many nodular well covers on the road. The patterns and words on the cast-iron well covers are different, and the purpose of the well covers is also different. Here is a brief introduction to the world under the bottom of these well covers. 1. Well covers of drainage engineering: for rainwater and sewage pipelines. 2. Well cover of water supply engineering: used in tap water, fire engineering, etc. 3. Well cover of heating engineering: applied to thermal arm line. 4. Well cover of power supply engineering: it is applied to power supply cable, telecommunication engineering, telephone and communication cable pipeline. 5. Garden engineering well cover: used for supporting comprehensive pipelines. 6. Gas engineering well cover: used in gas engineering, * * gas pipeline, etc. 7. Street lamp engineering well cover: used for power supply, lighting and cable pipelines.
