本热轧钢球生产线主要旋切球磨钢球,球磨钢球是筒形球磨机中用来粉磨矿块的一种研磨介质,广泛应用于铁矿和有色金属矿山选矿厂、水泥厂、火力发电厂、耐火材料厂、钢铁厂、磷肥厂等粉磨行业。
热轧钢球-耐磨钢球
HOT ROLLED STEEL BALL-GRINDING BALL
我公司是按国家标准生产热轧球磨钢球的企业。年产6万吨Φ20mm—Φ 150mm的球磨钢球。热轧球磨钢球技术是我公司开发的一项全新技术,其钢球轧机是由我公司自主研制而成,其质量优良,且公司选用优质特种钢作为原材料,在根本上提高了钢球的质量。
Jiangyin Jibang Machinery Co.,Ltd is a manufacturer of hot-rolled steel ball by national standards.The annual output of grinding balls is 60000 Tons.Hot-rolled steel ball process is a new technology developed by our company,it has a good quality.Our company choose the high quality special steel as a raw material,it fundamentally improves the quality of steel balls .
其工艺特色为:
①选择对应钢球规格的圆钢作为原材料②把圆钢加热至1080℃③通过钢球轧机一次成球④通过淬火,回火的过程使得钢球具有高韧性,破碎率极低,在各类矿山、各种规格磨机、各种恶劣环境下,长期使用稳定,效果理想。
Its process characteristics as follows :
①Choose the high quality special steel as a raw material.②Heat up the round bar to 1080℃.③Round bars are rolled to steel ball by skew rolling mill④The steel balls has high toughness and extremely low broken rate by quenching and tempering.It is stable in long-term use and the use effect are satisfactory in different mines,all kinds of grinding machines, all kinds of bad environments.
特点如下:
1、 高硬度、高耐磨、整体硬度高:表面硬度HRC57-67,心部硬度HRC56-64各,内外硬度差≤5HRC
2、 高韧性:冲击韧性≥12J/cm2
3、 破碎率极低:抗剥落及抗破碎性能强,落球冲击次数达20000万次近于无破碎,实际破碎率<1%
Parameters of hot rolled steel ball:
1. The overall high hardness: surface hardness of 57-67 HRC, volume hardness of 56-64 HRC, and the hardness gradient distribute evenly.
2. High impact toughness: more than 12 J/CM2
3. Low broken rate: anti-broken and anti-broken off performance is 10 times of general casting steel ball, balls impact times over 20,000 times, the actual broken rate is less then 1%, close to no broken
