High Manganese Steel Liner
production Description
High manganese steel liner is a kind of wear-resisting material with high strength, wear-resisting and toughness. is widely used in mining, cement, electric power, iron and steel and other industries.
The main features of high manganese steel liner are its excellent wear resistance and mechanical properties among which ZGMn13Cr2 and ZGMn18Cr2 are two common high manganese steel materials. The application of this material can significantly improve the durability and service life of the equipment, reduce the frequency of maintenance and replacement, thereby reducing production costs and improving production efficiency. The design and installation of high manganese steel liner should follow certain technical specifications, to ensure that it effectively protects the equipment from wear. , for example, the gap between adjacent lining plates should be controlled within 3~9mm, and should be laid between the lining plate and the ball mill cylinder body surface or filled with cement mortar with compressive strength grade according to the design requirements.
The use of high manganese steel liner not only improves the grinding efficiency of the mill, increases the output, also reduces the metal consumption, is an indispensable wear-resistant material in industrial production. It has a wide range of applications, including but not limited to mining, cement, electric power, iron and steel and other industries, provides important protection for the equipment in these industries.
Features
The main advantages of high manganese steel lining include high strength and toughness, good wear and impact resistance, and high adaptability.
high strength and high toughness: high manganese steel through the specific alloying element formula and heat treatment process, to achieve both tough and tough effect. its quenching hardness is as high as HRC45-55 or more ( is equivalent to HB about 390\~478) , impact toughness value is also more than 25J/cm². This characteristic makes the high manganese steel liner can withstand great impact without damage or deformation, can maintain stable performance in a long time of work.
Good wear resistance and impact resistance: When the high manganese steel lining plate is subjected to the direct friction of the abrasive body of the material, the cold work hardening phenomenon will occur on the surface, thereby enhancing its hardness and wear resistance. at the same time, it can also effectively resist the strong impact of the material without obvious damage. This characteristic makes high manganese steel liner show good durability and reliability in the field of mining equipment.
high adaptability: high manganese steel liner has a wide range of adaptability and use, is suitable for a variety of different types of wet, dry and mixed mine processing environment. Compared with other materials such as medium chromium cast iron, high manganese steel liner shows high applicability with its comprehensive properties and low cost, is one of the indispensable components in the field of mining equipment.
In summary, high manganese steel lining plate, because of its unique physical properties and mechanical strength, shows good economic benefits in practical application, is widely used in industrial fields, especially in improving the service life of equipment, improving production efficiency, reducing energy consumption and reducing emissions plays an important role.
