球墨铸铁的强度和铸钢的强度是可比的

  由于球墨铸铁的球状石墨微观结构,铸铁井盖技术要求1、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。2、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。

  Due to the microstructure of nodular graphite cast iron, the technical requirements of cast iron manhole cover, 1, to reduce vibration capacity, ductile iron is better than cast steel, so it is more conducive to reduce stress。 2。 One of the important reasons for the selection of nodular cast iron is that the ductile iron is lower than the cost of the cast steel。 The low cost of ductile iron makes this material more popular, higher casting efficiency, and less machining cost of ductile iron。

  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。性好。延伸率≥7%,与高碳钢材相近,而灰铁材料延伸率为零。

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

  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。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,其屈服强度最低为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。

  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。 The strength of the ductile iron is comparable to the strength of the cast steel。 The nodular cast iron has a higher yield strength, the yield strength is lowest 40K, and the yield strength of the 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 spheroidal graphite cast iron exceed the cast steel。

  济南球墨铸铁井盖特点:

  Characteristics of Ji'nan spheroidal graphite cast iron well cover:

  1、外形美观:线条简捷。银色外表,现代潮流。

  1, the appearance is beautiful: the line is simple. Silver appearance, modern trend.

  2、最佳排水:漏水面积达83。3%,是铸铁的两倍多。

  2, the best drainage: the water leakage area is 83.3%, which is more than two times the cast iron.

  3、防盗设计:盖与框用铰联接,防盗,安全,开启方便。

  3. Anti-theft design: the cover and the frame are articulated with the hinges. The security, security, and the opening are convenient.

  4、节省投资:大跨。重载时,比铸铁价低且节省被盗话压碎更换的费用。

  4, save investment: large span。 The heavy load, save the cost of replacement than stolen words crushed cast ironto。

  5、高 强 度:强度和韧性远高于铸铁,可用于码头,机场等大跨度和重载荷的环境。

  5, high strength: strength and toughness far higher than cast iron, can be used in wharf, airport and other large span and heavy load environment.

  6、规 格 多:满足不同环境,载荷。跨度,尺寸及形状所需。

  6, many specifications: to meet the different environment, load。 Span, size and shape required。
