本文以碎矿机中高锰钢锤头的实例,反映加钒试验的结果。由于高锰钢中加钒,使其金相组织、机械性能有明显改善。相同条件下,加钒高锰钢的耐磨性可提高20％。由于使用寿命延长,铸件的消耗相应减少,在扣除钒铁所增加的成本后,每用一吨加钒高锰钢铸件可节省60元左右。本文还根据硅还原渣中钒氧化物的原理,结合电炉炼钢工艺,提出含钒高锰钢重熔的冶炼工艺。并对进一步做好胀在高锰钢生产中的应用提出看法,供讨论。
In this paper, crushing machine high manganese steel hammer example, reflecting the results of vanadium test. Due to the high manganese steel plus vanadium, so that the microstructure, mechanical properties improved significantly. Under the same conditions, the wear resistance of vanadium-added manganese steel can be increased by 20%. As the service life is prolonged, the consumption of castings is correspondingly reduced. After deducting the added cost of ferrovanadium, it can save about 60 yuan for every ton of vanadium-added high manganese steel castings. Based on the principle of reducing vanadium oxide in silicon and combining with EAF steelmaking process, a smelting process of vanadium-containing high manganese steel remelting was proposed. And to further expand the application in the production of high manganese steel put forward their views for discussion.
