导致铸铁篦子生锈的原因有哪些?

铸铁篦子在使用的过程中,有的时候,会因为篦子生锈导致使用性能下降,使用寿命缩短。那么,在使用的时候,导致其出现生锈的原因有哪些呢?这就是小编今天想要跟大家来介绍的一个问题。

Cast iron grate in the use of the process, sometimes, because the grate rust will lead to performance degradation, shorten the service life。 Then, what are the causes of rust when they are used? This is a question that Xiaobian wants to introduce to you today。

如果铸铁篦子使用的环境中存在氯离子:氯离子广泛存在,比如食盐、汗迹、海水等。在氯离子存在下的环境中,腐蚀很快,甚至超过普通的低碳钢。所以对篦子的使用环境有要求,而且需要经常擦拭,除去灰尘,保持清洁干燥。

If there are chloride ions in the environment where iron grates are used, chloride ions are widespread, such as salt, sweat stains, seawater, etc。 In the presence of chloride ions, the corrosion is very fast, even more than ordinary low carbon steel。 Therefore, there are requirements for the use of the grate environment, and the need for frequent wiping, dust removal, keep clean and dry。

篦子被天生的晶间腐蚀:这种不含钛和铌的材料有晶间腐蚀的倾向。加入钛和铌,再配以稳定处理,可以减少晶间腐蚀。在空气中或化学腐蚀介质中能够抵抗腐蚀的一种高合金钢。

The grate is naturally intergranular corrosion: this material without titanium and niobium tends to intergranular corrosion. The intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. A high alloy steel that resists corrosion in air or chemical corrosive medium.

没有经过固溶处理:合金元素没有溶入基体,致使基体组织合金含量低,抗蚀性能差。所以大家要注意这方面的保护措施。

No solid solution treatment: alloy elements did not dissolve into the matrix, resulting in low alloy content in the matrix structure, poor corrosion resistance. Therefore, we must pay attention to the protection measures in this area.

以上三个方面就是常见的导致铸铁篦子生锈的原因,我们在使用过程中,一定要尽量为其提供一个有益的环境,这样能够减少篦子的锈蚀,延长使用寿命。

The above three aspects are the common causes of rusting of cast iron grate, we must try to provide a beneficial environment in the use process, so as to reduce the corrosion of the grate and extend its service life.
