油炸機(jī)為什么會發(fā)生腐蝕現(xiàn)象？

Why does the frying machine corrode?

在所有不銹鋼全自動油炸機(jī)腐蝕損壞后，不能采用更換損壞設(shè)備和零件的簡單方法。這不僅可以解決腐蝕和斷裂的問題，還會造成浪費。正確的方法是對自動煎炸機(jī)損壞的整體進(jìn)行嚴(yán)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，確定不銹鋼全自動油炸機(jī)腐蝕斷裂的性質(zhì)，找出引起腐蝕破壞的原因。

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

第二，提出防止或克服腐蝕破壞事故的措施，防患于未然，不使事故再現(xiàn)。

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

第三，收集和整理重要的現(xiàn)象和數(shù)據(jù)，為研究和驗證腐蝕斷裂機(jī)理提供可靠的依據(jù)。

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

為了針對所遇到的具體破壞事例進(jìn)行事故的分析，還要進(jìn)行實際工況或生產(chǎn)、使用現(xiàn)場的調(diào)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)全自動油炸機(jī)所使用的不銹鋼材生產(chǎn)工藝情況的調(diào)查。因為不銹鋼設(shè)備、部件的應(yīng)力腐蝕與鋼材本身的成分、性能、生產(chǎn)工藝條件、交貨狀況、表面質(zhì)量、應(yīng)力狀態(tài)等冶金因素直接有關(guān)。

(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)破損全自動油炸機(jī)的加工制造工藝過程的調(diào)查。要了解從不銹鋼材進(jìn)廠到加工制成設(shè)備的全過程。

(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)破損的全自動油炸機(jī)實際使用情況和破壞發(fā)現(xiàn)過程的調(diào)查，其中包括國內(nèi)正在使用的同類型設(shè)備情況的調(diào)查。因為產(chǎn)生與沒有產(chǎn)生應(yīng)力腐蝕破壞的同類型設(shè)備的對比，會給我們分析應(yīng)力腐蝕原因提供重要的線索。對產(chǎn)生應(yīng)力腐蝕的設(shè)的實際工況或現(xiàn)場的調(diào)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.
