如何提高球墨铸铁井盖的质量?

来源:http://www.zgcjxdw.com添加时间:2021-02-25 12:00:40

大家知道吗?影响球墨铸铁井盖的质量有很多因素,比如,设计工艺,材料,铸造工艺等因素。购买一件产品,都想长时间的使用,而不是用一段时间后就坏了。与其这样,我们还不如想点办法,提高其质量,球墨铸铁井盖也是一样,我们该采取哪些方法提高其质量呢?

Do you know? There are many factors affecting the quality of ductile iron manhole cover, such as design process, material, casting process and so on. When you buy a product, you want to use it for a long time instead of breaking down after a period of time. Instead of this, we might as well think of some ways to improve its quality. It's the same with nodular cast iron well covers. What methods should we take to improve its quality?

1、要有合理的铸造工艺。即根据铸件结构、重量和尺寸大小,铸造合金特性和生产条件,选择合适的分型面和造型、造芯方法,合理设置铸造筋、冷铁、冒和浇注系统等。以保证获得优良产品。

1。 Reasonable casting technology is needed。 That is to say, according to the structure, weight and size of the casting, the characteristics of the casting alloy and the production conditions, the appropriate parting surface, molding and core making method should be selected, and the casting rib, chill, pouring system and gating system should be set reasonably。 In order to ensure the quality of products。

2、球墨铸铁井盖铸造用原材料的质量。金属炉料、耐火材料、燃料、熔剂、变质剂以及铸造砂、型砂粘结剂、涂料等材料的质量不合标准,会使铸件产生气孔、针孔、夹渣、粘砂等缺陷,影响铸铁件外观质量和内部质量,严重时会使铸件报废。

2. The quality of raw materials for nodular cast iron well cover casting. If the quality of metal charge, refractory, fuel, flux, modifier, foundry sand, molding sand binder, coating and other materials is not up to standard, the casting will have defects such as blowhole, pinhole, slag inclusion, sand sticking, etc., which will affect the appearance quality and internal quality of the cast iron, and even make the casting scrapped in serious cases.

3、在生产球墨铸铁井盖的时候,一定要注意产品的质量,大家也知道球墨铸铁井盖是用来井口防护用。而且它的使用环境也非常恶劣,须具很高的耐腐蚀性,很强的抗压性能。

4、我们生产的井盖还应该具备很高的抗老化性能,一般球墨铸铁井盖出现的问题是破裂,破裂是因为铸造中热处理时温度过高,或者是在铸造中没有适当的加一些防止过硬改变适当的脆性造成破裂的有效成分。

4。 The manhole covers we manufacture should also have very high anti-aging properties。 The problem of the general ductile iron manhole cover is rupture, because the temperature is too high during the casting heat treatment, or is not effectively added in the casting to prevent the excellent change of the effective brittleness。

5、球墨铸铁井盖工艺操作,要制定合理的工艺操作规程,提高工人的技术水平,使工艺规程得以正确实施。

5. In the process operation of nodular cast iron well cover, it is necessary to formulate reasonable process operation procedures, improve the technical level of workers, and correctly implement the process procedures.

3d捕鱼由于球墨铸铁井盖在我们生活中涉及很多的场所,所以质量问题不容忽视,提高的产品的质量问题,使用的时间也长,还能减少故障产生。

As the ductile iron well cover in our life involves a lot of places, so the quality problem can not be ignored, improve the quality of the product, the use of a long time, but also reduce the failure.
