HSI Blow Bars Material Choice!

lundi 31 octobre 2016

There are five kinds of material which we(JYS Casting) used in manufacturing HSI blow bars.Different material suit for different HSI crusher working conditions.

High Manganese. This material is widely used in crusher jaws,crusher cones and crusher shells,not common in impact crusher. However, when crushing less abrasive and large feed material(such as limestone), the manganese blow bars are the best choice.

Martensitic Steel. Martensitic steel lie between manganese and chrome steel. It’s used if the impact load is too little to harden the manganese steel,and good wear resistance is required along with good impact stress resistance.

Chrome Steel. Chrome steel is the common material in casting HSI blow bars,because it has very good hardness. Regularly,chrome steel typically has a hardness of 60 to 65 HRC. And if we increase the elements “Mo” content, it also can get very toughness and wearable,not easy break.

Metal Matrix Composites. This combination makes HSI blow bars very wear resistant but at the same time very impact resistant.With blow bars made of composites from the surface of ceramics, the working life can reach three to five times than simple martensitic steel blow bars.

Titanium Tungsten Alloy. In order to increase span life of blow bars in different conditions,our foundry success to use titanium tungsten alloy to cast HSI blow bars. Under this material, the span life can reach more than 2 times compare to chrome steel blow bars.
