Heat resistant grate bars for wast incinerator or other
incinerators
Grate and grate bars are easily damaged parts which been widely
used for wast incinerator, biomass and coal-fired boiler, sintering
machine and other machines. It is produced by heat resistant steel
with different type of structures. We are able to produce and offer
a large range of grate bars by different materials or grate types.
With the support of our production team, we can cooperate with our
customers to improve their materials and designs in order to
increase the life span of their products.
We strictly comply with the high standards of production, pay
attention to the return charge percentage, process control and
product inspection to ensure our customers get right quality
products.

Shell molding is the most common process for our products for grate
or grate bars. By this process, we can get high quality castings
with good dimensional accuracy and high internal quality, but the
cost is not as high as lost wax castings. For higher requirement
castings, we use lost wax process as priority, and by this process
we can get best surface and dimensional quality.
For simple castings such as grate bars, we use both lost foam
process or shell molding process. By lost foam casting process, we
can get much higher production efficiency to reduce production
cost.
