Information

The standard of corrosion resistance of bucket elevator for cement plant is artificially determined. It is necessary to recognize it, use it, and not be constrained by it. It is necessary to determine whether it is a specific standard of corrosion resistance according to the actual application regulations. At this stage, the corrosion resistance of stainless steel mostly adopts the 10-level standard. Which level is selected as the corrosion resistance requirement, the bucket elevator for cement plant should be considered as the vertical conveying equipment, and the characteristics (thickness, size) of the parts should be considered. Length of service life, product quality (such as impurities, color, purity) and other requirements, generally speaking, for instruments and parts that require a clean mirror surface or precise dimensions during use, 1-3 standards can be selected; for close coordination, For equipment that does not leak for a long time or requires the use of length-limited equipment, the parts should be selected from grades 2 to 5.

Corrosion resistance is relative and conditional. It is often said that stainless steel is rust-resistant. Corrosion resistance refers to under certain conditions (medium, concentration, temperature, impurities, pressure, flow rate, etc.), relative to rusting and non-corrosion. . So far, stainless steel and corrosion-resistant stainless steel are not available in any corrosive environment. Therefore, the selection of bucket elevator materials must be selected according to the specific conditions of use. After the stainless steel grade is selected, the user department should also correctly use the characteristics of the selected stainless steel, that is, select the material reasonably and use it correctly to achieve the purpose of rust resistance or corrosion resistance.
When selecting stainless steel, not only its general corrosion resistance, but also its localized corrosion resistance should be considered. In some aqueous and chemical media, the latter requires more attention. This is because the material selection personnel of bucket elevator for cement plant usually pay more attention to the general corrosion resistance of stainless steel, and under the conditions of use, they are sensitive to localized corrosion, such as stress corrosion pit corrosion; in general corrosion resistance with good corrosion resistance In the environment, the local corrosion of stainless steel is more. Localized corrosion often leads to sudden damage to stainless steel equipment and parts, and its harm is far greater than general corrosion.
When using the corrosion resistance data of stainless steel in various manuals, it should be noted that many data are only some test results in experiments, which are often very different from the actual medium environment. In order to obtain corrosion resistance data that is closer to the actual use conditions, the test of the simulated device should usually be carried out in the laboratory for the corrosion test of the actual medium or the coupon test under field conditions.
In some applications, this kind of situation will also be encountered, when even a small amount of some metal ions in the stainless steel or in the industrial production commodity produced in the working medium will endanger the industrial production and manufacturing process. The quality of processes and industrially produced goods (including gloss, hue, purity, etc.). Such conditions are most prevalent in industrial production of fuels, pharmaceuticals, and pigments, where stainless steel or a moderately elevated corrosion-resistant grade of selected stainless steel is often chosen, in order to reduce metal ions to allowable limits. Understanding the delivery materials of the bucket elevator for cement plant also has practical significance for the selection of stainless steel materials.
If the parts of stainless steel manufacturing equipment fail due to corrosion, the cause of corrosion damage should be analyzed, and measures should be taken after finding out the cause.
In addition to the model, the material selection of the bucket elevator for cement plant is also very important. When selecting stainless steel in a corrosive environment, in addition to a detailed understanding of the specific application conditions of stainless steel, the main factors to be considered are: corrosion resistance, strength, toughness and physical properties of stainless steel, processing, formability, resources, price and difficulty in obtaining. Corrosion resistance includes the properties of stainless steel and corrosive media such as acid, alkali, and salt, as well as resistance to oxidation, vulcanization, chlorination, and fluorination. Since the selection of different stainless steels is mainly to solve various corrosion problems encountered by bucket elevator for cement plant in actual engineering, the corrosion resistance of stainless steel in corrosive environment is the first consideration for bucket elevator design and material selection personnel. question. Corrosion is the damage caused by chemical or electrochemical action between metal and medium, and corrosion resistance refers to the ability of stainless steel to resist medium corrosion damage, so when the selection of bucket elevator materials involves corrosion resistance, more attention should be paid .
