Steel drums or flexible container bags

We manufacture the product with the length of 2m to 6m and the diameter of 40mm to 140mm. Our product is characterized by low wear, unique chemical composition, high hardness of 45HRC to 55HRC and strong toughness. In addition, internal stress is removed by quenching and high temperature tempering treatment. Furthermore, our product has good straightness, and we can guarantee that problems such as break, bend or entanglement won’t occur during the service life of our product.

Ï?40-120mm, Length 2-6m ( HRC45-55)
The grinding rod has high hardness(45-55HRC),low wear friction,strong toughness,The wear-resistant effect is 1.5 to 2 times the raw steel rod,after refining,the internal stress was relieved.So the rods are perfectly straight and not break,,Two head not nozzle, and with good wear resistance.

Grinding steel rods:
Diameter: 50-120MM
Length: tailored.
Hardness: HRC45-55
Application: Various rod mills for metalic mines,phosphate mines,silca sand makings.

Charateristics: high hardness,no bending in the application,good wear resistance with long life.

The grinding rods are produced by alloy steel materials, which have got the national patent.

The grinding rods with heat treatment can improve the production and decreased the consumption up to 30% than the round steel bars used in the international market.

We have one complete strict quality control systems from the materials, production process and finished products to ensure the steady quality of the grinding rods.Each piece of grinding rods has to be inspected qualified before delivery.

Grinding steel rod, our company manufacture and export is as follows:
1. Specifications:
1) size: dia. 40 - 120mm, length 3000-6000mm

Product Description
1.Features and Advantages of Grinding Steel Rod
Concentrating on wear-resistant grinding material for 30 years, is one of the largest grinding rod manufacture in . We manufacture the product with the length of 2m to 6m and the diameter of 40mm to 140mm. The data is just for reference. The product can also be customized.
After years of research and development, we finally develop the new-type steel grinding rod successfully. The newly developed product is characterized by low wear, unique chemical composition, high hardness of 45HRC to 55HRC, and strong toughness. Meanwhile, via the quenching and high temperature tempering treatment, the internal stress is removed. The product has good straightness, and won't break, bend and come out with two tapering ends. The economic benefit is much in evidence.
a. The blanking of the steel grindng rod is implemented via the sawing machine. The dimensional tolerance would adide by the requirements of the order. After the implementation of blanking, the two ends of the raw material are polished into the R arc via the polishing machine.
b. The surface of the product for the rod mill cannot have the crack, overburning and fissure visible to the naked eyes.
c. The nonstraightness of the product is less than 0.2%. The diameter tolerance ranges from +0mm to -1.5mm. The length tolerance is fro +0mm-25mm. The fracture should be less than 3%.
2. Specification of Grinding Rod
AS in the following sheet.
1) Size: Dia. 40 - 120mm, Length 2000-6000mm
2) Hardness: HRC 45-55
3) Chemical elements(%):
