Description

复合碳硅锰钡铝合金块
本发明涉及炼钢工艺过程的合金化,终脱氧,增碳,三位一体的一种新型多元素合金块。
目前大部分冶金炉合金化都在炉外进行。由于合金的比重不同,易造成钢的成分不均匀,脱氧剂与脱氧用的合金都是单一的合金,都要分别加入,脱氧效率低,除了影响钢质量外,又不经济。本产品既适用又经济,给应用厂家带来较大的经济效益。
本发明的任务是:利用炼钢用的铁合金破碎的筛下料及渣中精选出来的合金粒,经再粉碎、配入不同含量的其它合金及催化剂、速溶剂、粘结剂,再经压力加工成块,生产出一种多元素的复合碳硅锰钡铝合金压块。以铁合金合金化的形式加入钢包中,既起合金化作用,又能增碳,还可代替一般钢号的终脱氧铝。此合金比重小于钢水大于钢渣,配入速溶剂及催化剂的快速反应及扩散使钢的化学元素快速均匀,能保证钢的化学成分均匀,脱氧好,钡的参入又能使钢晶粒细化。保证了钢的力学性能和提高钢的内在质量。
本发明是如下方式实现的:
采用配方C3-14%;Si14-16%;Mn60-65%;Ba0.5-2%;Al2-4%;催化剂0.05%;速溶剂0.05%;粘结剂1.4%。经破碎,物料表面处理,用混料器混均,然后压坯成型、烧结。
其制作工艺:
1.将物料用破碎机及球磨机破碎至-100目以下;
2.由一组振动筛给料机按各种合金,速溶剂,催化剂,粘结剂比例配料;
3.混料机将配好的物料混匀;
4.用专用压力机在1200kg/cm2下将料压坯成型;
5.在150℃-200℃条件下烧结24小时,成为合格品。
采用本发明的配方及工艺生产的复合碳硅锰钡铝合金块具有以下优点:
(1)成分易于控制,产品质量稳定,P<0.20%;S<0.05%;H2O<0.50%;
(2)生产出的复合碳硅锰钡合金块强度高。表面规整,比重适中,易于运输,不粉化,适用于炼钢炉外合金化工艺,使多种合金变为一种多元素合金,节约能源,节约铁合金,提高经济效益;
(3)原料来源广泛,生产工艺易于掌握,成品率高,成本低。
图1为本发明的复合碳硅锰钡铝合金块横截面。
图2为复合碳硅锰钡铝合金块生产工艺流程图。
本发明的一个最佳方案:以制作1000kg复合碳硅锰钡铝合金块为例:选用配料硅锰粉(或硅粉、锰粉)915kg、碳40kg、速溶剂0.5kg、催化剂0.5kg、粘结剂14kg、铝粉15kg、硅钡粉15kg,将上述各原料破碎-100目以下,然后对其表面加以处理,使物料露出新鲜表面,然后由一组振动给料机按照合金、催化剂的总量比例配料,用混料机将配好的物料混均,配入液体粘结剂混均,由专用压坯机在压力1200kg/cm2条件下压成坯,最后在150℃-200℃条件下烧结24小时成为合格品。
