What is the nature of the mining bimetal composite liner?
The mining bimetallic composite liner has been of different grades and representativeness in the world, but the basic concepts are similar. Let's take a look at the chemical properties of the bimetallic composite liner:
The mining bimetallic composite liner has been of different grades and representativeness in the world, but the basic concept is similar
Under the technical conditions of existing enterprise products, the high-strength mining bimetallic composite lining plate is not the standard brand Drawing on the standards of foreign companies and the actual situation of our country, the achievements of our high-strength bimetallic linings are mostly imported brands. The current use is confusing. We should adopt the naming of grades and unify them. We should promote the use of common standards and the development of high-strength bimetallic linings with high promotion standards, and the high-strength Jiangsu bimetallic lining system GSM. The value of the combination (HB) of the user's bimetallic composite liner plate, Jiangsu bimetallic liner plate brand selection and the use of Pinyin Brinell hardness consistent with the embodiment.
The mining bimetallic composite liner construction machinery is generally made of traditional high manganese steel. Although high manganese steel is strengthened, it has a strong hardening ability under impact stress in future use. It can only play a large impact load in its role, and the wear resistance under the impact condition of small load cannot be improved by hardness and hardening of high manganese steel. The yield strength is not high, and the workpiece can also crack under a large force, It is difficult to achieve the required service life.
Therefore, compared with high manganese steel, in recent years, low alloy is used to produce small and medium-sized bimetallic composite liner mechanical parts, which can be applied in the field of mechanical engineering. The high manganese steel used in the extension and expansion is recognized by the mechanical industry and has become a trend.
