2, the use of anti rust lubricating oil, cleaning kerosene and other products of the quality of the product can not reach the requirements of the technical requirements.
3, due to the gradual decline in the price of the chain steel, resulting in a gradual decline in the chain steel material. Such as the high content of non-metallic impurities in steel and metallographic structure deviation, etc.. The production enterprise is used to produce the chain of the chain steel material is poor.
4, the chain is located in the location of the poor environmental conditions, high levels of harmful substances in the air, the turnover of the site is too small, it is difficult to carry out effective anti rust treatment. Coupled with the hot weather, the production workers in violation of the rules of rust prevention and so there is no lack of.
