重型球墨井盖的材料必须是铸铁打造

来源:http://www.kpp647.com添加时间:2018-02-09 18:29:48

1应用范围和场合不一样。重型井盖一般应用于载荷比较重的场合,比如机场,高速路,码头,二环路,城市快速路等,这种场合有一个共同的特点就是经过会受到高负荷和重压。

1 the application range is different from the situation. The heavy shaft covers are usually applied to heavy load occasions, such as airports, highways, wharfs, two loops, urban expressways, etc. this situation has a common feature, that is, it will be subjected to high load and heavy pressure.

2材料不一样。材料不一样是指,重型球墨井盖的材料必须是铸铁的,因为只有铸铁材料才能达到要求的强度,而普通的井盖材料可以应用铸铁也可以应用其它的材料,比如复合材料,树脂材料,高分子材料等。

2 materials are different。 The material is not the same as that of Heavy Ductile iron manhole cover material must be cast, because only cast iron materials in order to meet the requirements of the strength, and covers the common materials can be used cast iron can also be applied to other materials, such as composites, resin materials, polymer materials etc。。

3产品的细节不一样。重型球墨铸铁井盖厚度要比一般的井盖厚出很多,而普通的井盖则从重量上要轻很多,厚度上要薄很多。

The details of the 3 product are different. The thickness of the heavy ductile iron shaft cover is much thicker than the general well cover, and the common well cover is much lighter from the weight, and the thickness is much thinner.

山东球墨铸铁井盖

球墨铸铁井盖是球墨铸铁产品的一种,球墨铸铁通过球化和孕育处理得到球状石墨,有效地提高了铸铁的机械性能,特别是提高了塑性和韧性,从而得到比碳钢还高的强度。

The ductile iron manhole cover is a kind of ductile iron product. Nodular graphite cast iron is spheroidizing and inoculating to obtain spherical graphite, which effectively improves the mechanical properties of cast iron, especially improves plasticity and toughness, so as to get higher strength than carbon steel.

球墨铸铁的成分含碳量大于2%的铁碳合金,工业生铁含碳量一般在2。5%--4%,并含C、SI、Mn、S、P等元素,是 用铁矿石经高炉冶炼的产品。根据生铁里碳存在形态的不同,又可分为炼钢生铁、铸造生铁和球墨铸铁等几种。析出的石墨呈球形的铸铁。

The iron carbon alloy nodular cast iron composition containing more than 2% C, industrial iron carbon content is generally in 2.5%--4%, including C, SI, and Mn, S, P and other elements, is the use of iron ores in blast furnace smelting products. According to the different forms of carbon in the pig iron, it can be divided into iron making, cast iron and spheroidal graphite cast iron. The precipitated graphite is spheric cast iron.

球状石墨对金属基体的割裂作用比片状石墨小,使铸铁的强度达到基体组织强度的70~90%,抗拉强度可达120kgf/mm2,并且具有良好的韧性。球墨铸铁除铁外的化学成分通常为:含碳量3.6~3.8%,含硅量2.0~3.0%,含锰、磷、硫总量不超过1.5%和适量的稀土、镁等球化剂。

The splitting effect of spherical graphite on metal matrix is smaller than that of flaky graphite. The strength of cast iron reaches 70 to 90% of the strength of matrix, and its tensile strength reaches 120kgf/mm2, and has good toughness. The chemical composition of ductile iron for removing iron is usually: carbon content 3.6 ~ 3.8%, silicon content 2 to 3%, manganese content, phosphorus and sulfur content not more than 1.5% and proper amount of rare earth and magnesium nodulant.
