摘要
铁合金连续成型技术经实验室的探索研究,找到了适合锰硅合金的连续铸造方法,为了使该项技术能够工业化,在广西八一铁合金集团有限公司兴建了一条年产12 500 t的连续铸造设备,并在此设备上完成了锰系铁合金的中试试验。依据连续铸钢的理论,对铁合金连续铸造所用的结晶器振动参数以及铸坯的拉速进行合理设置和修正,探索出适应于锰系铁合金连续成型的工艺技术条件,与连续铸钢的工艺相比,锰系铁合金由于其高的硬脆性实现连续成型比较困难,但在低频率、低振幅、较低拉速和合理的冷却能力下依然可以顺利进行。这种成型技术应用的最大优势就是可以减少合金的疏松和成分偏析,因而大大降低合金成型过程中的成粉率。
The continuous casting technique of research in a labotatory for one year, In order caster with 12 500 ton annual output was built silicon manganese ferroalloy was obtained through to apply the technology in industry, a single-strand in Guangxi Bayi Ferroalloy Co., Ltd, and medium experimentation was achieved for manganese ferroalloy. Drawing speed of casting blank and oscillating parameter of crystallizer were set and modified reasonably to ferroalloy on the basis of theory of continuous casting steel. Technological condition suiting for manganese series ferroalloy was found. Compared with the technique of continuous casting steel, the continuous casting of manganese ferroalloy is difficult to achieve due to high hardness and brittleness of the ferroalloy. However the technique can be completed at low frequency, low amplitude, low drawing speed and reasonable cooling capacity. The most advantage of the technology is to decrease porosity and component segregation, thus significantly decreases powder of ferroalloy.
