油炸机为什么会发生腐蚀现象？

Why does the frying machine corrode?

在所有不锈钢全自动油炸机腐蚀损坏后，不能采用更换损坏设备和零件的简单方法。这不仅可以解决腐蚀和断裂的问题，还会造成浪费。正确的方法是对自动煎炸机损坏的整体进行严重事故分析，其主要目的是:　

The simple method of replacing damaged equipment and parts cannot be used after all stainless steel automatic frying machines are corroded. This can not only solve the problems of corrosion and fracture, but also cause waste. The correct method is to conduct a serious incident analysis of the overall damage of the automatic frying machine. The main purpose is:

第一，确定不锈钢全自动油炸机腐蚀断裂的性质，找出引起腐蚀破坏的原因。

First, determine the nature of stainless steel automatic frying machine corrosion fracture, to find out the cause of corrosion damage.

第二，提出防止或克服腐蚀破坏事故的措施，防患于未然，不使事故再现。

Second, put forward the measures to prevent or overcome the corrosion damage accident to prevent the accident from happening again.

第三，收集和整理重要的现象和数据，为研究和验证腐蚀断裂机理提供可靠的依据。

Thirdly, important phenomena and data are collected and collated to provide a reliable basis for the research and verification of corrosion fracture mechanism.

为了针对所遇到的具体破坏事例进行事故的分析，还要进行实际工况或生产、使用现场的调查。

In order to analyze the specific damage cases, it is necessary to investigate the actual working conditions or the production and use sites. 

(1)全自动油炸机所使用的不锈钢材生产工艺情况的调查。因为不锈钢设备、部件的应力腐蚀与钢材本身的成分、性能、生产工艺条件、交货状况、表面质量、应力状态等冶金因素直接有关。

(1) investigation on the production process of stainless steel used in automatic frying machine. Because the stainless steel equipment, parts of the stress corrosion and steel itself composition, performance, production conditions, delivery status, surface quality, stress state and other metallurgical factors are directly related.　

(2)破损全自动油炸机的加工制造工艺过程的调查。要了解从不锈钢材进厂到加工制成设备的全过程。

(2) investigation on the processing and manufacturing process of the damaged automatic frying machine. Understand the whole process from stainless steel entry to finished equipment.

(3)破损的全自动油炸机实际使用情况和破坏发现过程的调查，其中包括国内正在使用的同类型设备情况的调查。因为产生与没有产生应力腐蚀破坏的同类型设备的对比，会给我们分析应力腐蚀原因提供重要的线索。对产生应力腐蚀的设的实际工况或现场的调查。

(3) investigation of the actual use of the damaged automatic frying machine and the process of damage discovery, including the investigation of the same type of equipment in use in China. Because the comparison of the same type of equipment that produces and does not produce stress corrosion failure will give us important clues to analyze the causes of stress corrosion. Investigation of the actual working condition or field of the hypothesis producing stress corrosion.
