HUAMIN Grinding rods
is widely used in the mining and cement industry. HUAMIN Grinding
rods is different with common round steel bars, it is heat treated
grinding rods used in the Bar Mill, the wearing resistance is much
higher than common round steel bars by **6 time, the performance is
obvious.
HUAMIN Grinding rods
can fully produce according to customer’s requirement, the main
technical parameter is as
follows:
1. Diameter:
*8mm***0mm
2. Length:
**6m
3. Hardness: can be
produced by customer’s requirement, the common hardness is
HRC****5
4. Raw material: High
quality, and can be customized.
5. We can also
acceopt customer’s material for
processing.
The main question
analysis
1.Analysis for
breakage and bending of grinding
rods
a. main reason:1)
Material: Porosity and light
segregation existed within rolled steel and the inner mechanical
property is poor relatively. Only big steelworks can meet the
technical requirement of inner tightness. Especially size more than
*0mm, the compression ratio and hardenability characteristic is
poor even though the steel billet of most steelworks can finish the
moulding. 2) Process: the inner stress is not relieved. The
breakage of grinding rods is same like blast, which is happened
from the inside. Only the inner stress is relieved, it can avoid
the breakage.
b. Solution: 1) We
use raw material from big steelworks, and our new type alloy steel
material is developed by our company, which is has good
hardenability characteristic, also we have confidential agreement
with the steelworks.2)We have get patent of our developed grinding
rods process, which can highly improve the wear resistance of the
grinding rods, and no breakage.
2. Hardness of the
grinding rods
The optimum status is
HRC****0 of the grinding rods, we think, and if the hardness is
lower than HRC****0, the wear resistance will not be good, and if
the hardness is higher than HRC****0, the breakage rate will be
higher. The common hardness of rods from the steel makers is only
HRC****5, so the wear resistance of our grinding rods is much
higher than the round bars from the steel
makers.
We sincerely welcome
customers at home and abroad to visit our factory, and we will try
our best to offer best quality products, timely delivery,
competitive price and satisfactory service for our long-term
cooperation.
