Product Details

 

 

 

 

 

 

Specifications

1.High hardness, 
2.Good wear resistance and long life, 
3. Unbreakable, 
4.HRC:50-65 
5.High impact toughness 

 

Production Process of Grinding Steel Rods:

 

1.The blank used for producing the grinding alloy steel rods is hot-rolled bars with various kinds of  chemical compositons.Its diameter is the same as the nominal diameter of steel rods.

2.Bars are reheated to a proper temperature in a contious furnace.

3.After a red hot bar is conveyed into the furnace,it is transported directly to the online heat treatment equipment,specially designed for steel rods quenching and tempering.Alloy steel rods can obtain

very high and uniform hardness .

4.Finished steel rods are charaterized by the precise dimension and geometry,better anti-wear  properties and mechanical properties.

5.The products which passed inspection are transported to the finished product storehouse and then delivered to customers after being packed.
