球墨铸铁井盖的热处理工艺

来源:http://www.kpp647.com添加时间:2017-03-07 14:34:00

球墨铸铁井盖的热处理工艺是利用加热和冷却这两种方法进行,这样可以有规则的去改变铸铁的内部组织结构.

The heat treatment process of nodular cast iron manhole cover is carried out by heating and cooling of the two methods, the internal organizational structure to change the rules so that there can be cast.

从而使井盖获得材料本身对应的性能,这样才能满足重型车辆道路的需要,在硬度、韧性、耐磨性、强度、塑性等方面得到了很好的表现。

The performance so that the material itself covers corresponding, so as to meet the need of heavy vehicle road, has a very good performance in hardness, toughness, wear resistance, strength, plastic etc..

球墨铸铁井盖的每一个热处理过程的工艺都是在井盖固体状态下进行加热的,采用加热、冷却和保温三步工序制成的。

The process of each heat treatment process of ductile cast iron manhole covers are heated in solid state under the covers, heating, cooling and heat preservation is made of three steps.

铸铁件生产除了需要一些比较合适的化学成分来达到控制内部组织之外,而且热处理还能够控制和改进基体组织的结构,从而还能够达到提高铸铁的使用性能。

Cast iron production in addition to some of the more suitable chemical composition to control the internal organization, structure and heat treatment can control and improve the microstructure, which can improve the performance of cast iron.

球墨铸铁的热处理与钢的热处理有一样的地方,也有不同的地方。在热处理的方法中球墨铸铁是模仿钢的生产的处理工艺,但在工艺参数方面由于石墨的存在,金属固体和化学成分的都不同,使铸铁的热处理具有一定的特殊性。

The heat treatment of nodular cast iron is the same as that of steel. In the heat treatment of nodular cast iron is the production process of steel imitation, but in terms of process parameters due to the presence of graphite, solid metal and chemical composition are different, so that the heat treatment of cast iron has a certain particularity.

不管球墨铸铁采用什么方式制成的,在加工处理中一定要首选保证球墨铸铁有足够大的强度,因为这关系到市政道路上行人和车辆的安全。所以相对于其他井盖来说,球墨铸铁井盖的承载能力还是很大的。

No matter what kind of ductile cast iron is made, in the processing must be the first choice to ensure that ductile iron has a large enough strength, because it relates to the safety of pedestrians and vehicles on Municipal roads。 So compared with other covers, the bearing capacity of ductile iron manhole cover is great。
