Advantage of high manganese steel blow bar: 

1. Long service life, light weight, thin thickness and power consumption.
2. Fast replacement and maintenance, easily installed and need less labor work.
3. Widely used for high, medium, and weak magnetic mineral.
4. Attached on the inner wall of cylinder by magnetic force, no pulp leakage and highly efficient.
5. Can be used for nonmagnetic mineral substance, but certain quantity of ferromagnetic substances such as broken steel balls and scrap iron must be added form protection layer.
Technology Process:
1. Employ the external refining technology effectively reduced the harmful elements, impurity and oxygen and hydrogen harm, greatly enhanced the abrasion resistance and impact toughness of the steel.
2. Using proprietary metamorphic agent for modification treatment, fine grains, improves carbide configuration and distribution, and to improves the abrasion resistance and tenacity.

3. Optimizing heat treatment process, make the product of uniform hardness especially, impact abrasion resistance becoming stronger.

Company information:

Our company is a professional manufacturer of wear-resistant materials and anti-friction materials. Our company was established in 1993 and has passed ISO9001:2000 International Quality Management Certification.

   Our business scope covers bimetal thermal-composite materials, a series of alloyed and super high-Manganese hammers, a series of medium high alloy steel materials and a series of high-chromium alloy iron wear-resistance products such as hammer heads, board hammers, hammer block lining plates and comb plates.

   We developed the following series of products with our hard work in science and research projects:

   In 1998 the alloyed super high-manganese hammer was launched into Chinese market. It won the honor of "Hard stone killer" with its excellent properties and high cost performance. 
  In 2002 the super high-manganese materials series were developed and the spare parts of crushers and mill equipment supplied by globally famous companies (such as Germany Aubema, Krupp & Hazemag) were made in China.

   In 2004, bimetal thermal-composite wear-resistance materials (China Patent No. 200810049101) were developed, and we have whole intellectual property. We successfully combined two different features of high-hardness materials and high-ductile materials together for the whole work. Thus our products are featured by abrasion resistance and impact resistance with excellent performance. Our products are especially applied to the hammers and board hammers of large crushers and the lining plates of large ball mills with remarkable effects particularly when our products are used in harsh environment for many crushing fields such as limestone, cement, clinker, sand stone, coal, spoil basalt and others.
