| Meishan Iron and Steel Company converter reduce the oxidation rate of molten steel had achieved results
r2MoWVNI nitride with and without nitrogen feeding hot forging die life are HI1】 steel 150.8% and 65.5%, while the cost price of 4Cr2MoWVNi guillotine and H11 steel cylinder is roughly equal to j {die life extension, each lower cost of production forgings, rings and has a high economic benefits and promote the value of respect. 5 Conclusion (1) 4Cr2MoWVNi the best heat treatment process for steel: quenching +590 1000 Shantou. ℃ second tempering (2) 4Cr2MuWVNi steel quenched by the Organization for the lath martensite, granular carbide + austenite to stay a few jiao, the group tempered sorbite + {is tempered Liu granular carbon, and carbon fine and homogeneous distribution of matter. The thermal stability and strength and toughness than H11: Information: Steel: (3) 4Cr2MoWVNi nitriding steel for hot forging dies and does not link the life of nitride is about H1t of I. 5 times,ed hardy, significant economic benefits. Touch in the hot forging press die application.

Beijing: Machine Industry withdrawal of T mn. 2o00 received revised :2005 -07-29 Meishan Iron and Steel Company converter reduce the oxidation rate of molten steel over the effectiveness of Baosteel Group Meishan Iron and Steel made to the implementation of standardized operating steel mill, to launch research and other staff to carry out self-management measures to reduce steelmaking converter blowing over water oxidation rate,stivali ugg, and achieved good economic molten peroxide not only shorten the converter lining life, but also reduce the Taijin yield, increase the consumption of refractories and the cost of oxygen scavenger. Steel mill led to the causes of copper water peroxide through scientific analysis, through the promotion of advanced methods of operation. Improve the oxygen lance operation by energy, steel-making model and automatically play ERE role of production management systems to reduce the oxidation rate of molten steel too. Converter operator also \Through the efforts,ugg prezzo, molten steel mills have reduced the oxidation rate of 15 percent, reducing the material consumption of converter furnace protection,ugg stivali, extending the transfer Shanghai life and reduce the Taijin costs. Only a monthly consumption of aluminum Taijin can save 43 million yuan.
