Product Description

CITICIC is the leader in offering wear solutions to crusher operators in China. We provide wear parts with designs and alloys specifically developed for each application and specific location within each crusher.Our crusher parts are made of manganese steel – the toughest and most wear-resistant steel available. In addition to the crusher components listed above, we also make cast components for the crusher itself such as the pitman arm, side plates, cheek plates, etc.

GENERAL DESCRIPTION

Wear components for crushing processes are subjected to severe impact and high abrasion, requiring components made from impact resistant and abrasion resistant alloys.
We increase crusher availability through:
• Increased wear life
• Less on-going wear part maintenance
• Designs and tools for quicker change out

Blow Bar

According to the characteristics of the global equipment, our experts, after long and careful research and long term experiment, produce the world-class sound quality material by making reasonable composition of super-high manganese material and specially treating them with variety of optimization modification. Our high quality impact crusher spare parts using this material above have successfully replaced the counter-attacking blow bar of Germany Hazemag and ect. Compared with similar imported products, our impact crusher parts have many advantages, such as safety, wear resistance, low price, ect., and short delivery time.Impact hammer sells well in many countries.

High Chrome Blow Bar

Our blow bars produced using abrasion resistant high chromium white cast iron material. While producing:

Using progressive solidification process and making Cr7C3 type carbide vertical growth against the working face. In the case of not lower the toughness of the parts, Meanwhile Cr7C3 type face macro hardness and micro hardness also increased.
Using multiple micro-alloyed methods to receive dispersion strengthened and progressive hardening and impact crusher wear parts .
Using annealing, quenching, tempering heat treatment process to make the blow bars’ surface hardness reaches 58-65HRC.

The specification of the impact crushers become bigger and the crushing capacity also become bigger. The impact crushers are widely used in construction industry, metallurgy, mineral processing, chemical industry and etc. Impact crusher is especially suitable for crush medium hardness brittle materials, such as limestone, coal, sandstone, cement clinker, iron ore, aluminum ore, and molybdenum ore for coarse, intermediate and finely crushing. Blow bars are the main impact crusher wear parts of impact crusher, mainly bear erosion and abrasives wear from the crushed material. The Germany crusher parts blow bars requires high hardness and certain impact toughness, so the high chromium cast iron is the most suitable material for the blow bars.

High chromium cast iron blow bar is of wear-resisting, because its matrix contains certain amount of Cr7c3 type carbide. The carbide quantity and distribution direct influence the performance of the blow bars. If Cr7C3 type carbide disorder distribution, the micro hardness of the part is 1300-1800 HV. However, if Cr7C3 directional distribution, the axial section micro hardness will reach more than 1800HV. After microalloyed, the micro hardness will be up 2000HV. This is also the main reason why directional solidification can improve the wear resistance of the high chromium cast iron. The blow bars of our company all adopt the technologies of directional solidification, compound modification treatment. We use multiple micros alloying to improve the carbide micro hardness and reasonable selection of Cr/C value, control the type and content of the carbide. So our high chromium blow bars can satisfy different users’ requirement at all kinds of working conditions.

Our blow bars can be compared with Germany crusher parts and had been widely recognized by customers at home and abroad market after they launch the market and the market share is improving constantly.

High Manganese Blow Bar

Blow bar is the main crusher spare parts of impact crushers. After water toughening treatment high manganese blow bar has very high impact toughness, which has the incomparable advantage over other wear-resistant materials. Our company produces the series of high manganese blow bar are: ZG120Mn13Cr2, ZG120Mn18Cr2, ZG120Mn13Cr2 tungsten titanium alloy blow bar, which mainly used in high hardness materials and hard broken condition. Super-high-manganese steel hammer after water toughening treatment, then using the aging tretment process,make the austenitic matrix dispersion distribution in the abrasive particles,thus greatly improve the wear resistance of high manganese blow bar.

The invention of high manganese steel material crusher spare parts has a history of more than one hundred years. Becauseof its excellent work hardening properties(maxium work hardening capacity is over 600 HBW), and make it has high wear resistance. The harder external shocks high manganese material crusher spare parts is attached,the higher wear resistance high manganese crusher spare parts. With the gaddul wear and tear of surface hardinglayer,the new will continuously form.So our high manganese crusher spare parts series blow bar issuitable for the complex structure, the big impact, high toughness condition.High manganese blow bar: while casting, we not only add molybdenum,vanadium,titanium, nickel, boron and other rare alloy elements. Meantime, wespecially adopt variety of alloy modifier to strengthen the matrix. Those blowbars use refining, vacuum casting, directional solid and etc technical’s toincrease the grain refinement and make the hammers performance achieve the bestperformance. Our crusher spare parts have successfully replaced the counter-attackinglarge Blow Bars of Germany Krupp, Blow Bars of Germany Aubema, counter-attackingBlow Bars of Germany Hazemag and make them nationalization.
Details:
· Emply the external refining technology effectively reduced the impact crushers, impurity and oxygen and hydrogen harm, greatly enhanced the abrasion resistance and impact toughness of the steel.
· Using proprietary metamorphic agent for impact crushers, fine grains, improves carbide configuration and distribution, and to improves the abrasion resistance and tenacity.
· Optimizing heat treatment process, make the product of uniform hardness especially, impact abrasion resistance becoming stronger.
