High Chrome and High Manganese Impact crusher blow bars
Products 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.
