为了进一步肯定16Mn钢中加稀土的效果,我们在300吨倾动式碱性平炉上做了三炉不同稀土加入量及轧制方法的对比试验。一、试验方法及试样制备(一)钢的冶炼及浇注:1.熔炼成分,%。C 0.12～0.20;Si 0.40～0.60;Mn 1.30～1.60;P~0.04;S~0.04,加铝量400克/吨。2.稀土硅铁含R_xO_y 30%,Si 40%,Ti 3～5%。其加入方法是:将稀土硅铁加热至800℃以上焙烧,然后冷至炉前温度,装入纸袋内,待钢水用铝脱氧后加于钢水流中,

In order to further confirm the effect of adding rare earth in 16Mn steel, we compared the addition of three rare earths and the rolling method in a 300-ton tilting alkaline open hearth furnace. First, the test methods and sample preparation (A) of steel smelting and pouring: 1 smelting composition,%. C 0.12 to 0.20; Si 0.40 to 0.60; Mn 1.30 to 1.60; P to 0.04; S to 0.04, aluminum content 400 g / t. 2. Rare earth ferrosilicon containing R_xO_y 30%, Si 40%, Ti 3 ~ 5%. The joining method is: the rare earth ferrosilicon is heated to above 800 DEG C, then cooled to the temperature in the furnace, and then filled in the paper bag. After the molten steel is deoxidized with aluminum and added to the molten steel flow,
