Mining Equipment Castings And Forgings With High Manganese Steel
1. Characteristics of high manganese steel castings and forgings
High manganese steel has good plasticity and impact toughness, under the impact of external force surface hardening layer, has hardened surface layer is worn, the appearance of a new surface layer, and continue to be work hardening. Therefore, high manganese steel castings have high surface wear resistance, and the inner part retains the original mechanical properties. Because high manganese steel has the above characteristics, so there is no wear-resistant material in the world can completely replace high manganese steel.
2. High manganese steel castings and forgings product parameters
| Main Chemical Composition (%) | |
| C | 1.0—1.4 |
| Mn | 11一14 |
| Si | 0.3—0.8 |
| P | ≤0.07 |
| S | ≤0.04 |
3. Performance indicators of high manganese steel castings and forgings
(1) Initial hardness HB 179 -- 229.
(2) In normal use, the casting will not appear fracture phenomenon.
(3) Take φ2.2 raw material ball mill as an example, the normal service life of the head bin lining board is more than 18 months (most cement factories reflect the use of more than two and a half years); The second bin lining board is more than 30 months (most cement plants reflect the use of more than 4 years).
4. Products with high manganese steel castings and forgings are recommended
Due to the advantages of high manganese steel castings with good toughness, wear resistance, high reliability and cheap price, most cement plants of various ball mill lining board; Hammer crusher hammer head, screen strip, lining board; Jaw crusher jaw plate, edge guard plate; Shaft machine jaw plate and so on use high manganese steel castings.
