Mechanical Wear-resistant Castings Wear Resisting Vertical Mill Roller Shell Grinding Parts
Description
The roller sleeve is the main spare part of the vertical mill, so the quality of the product directly affects the normal use or operation progress of the vertical mill. Hefei Hengcheng sells various models of high-quality vertical mill roller sleeves, with reliable quality and high wear resistance.
【Material】 High chromium
【Application equipment】 Cement vertical mill, mineral powder
vertical mill, coal mill
Product advantages
1. According to the usage environment of the roller sleeve, choose
to use high chromium material with high hardness and good wear
resistance;
The process of vertical grinding high chromium roller sleeve Cr20
using metal mold casting is used to obtain a structure with an
austenitic matrix, no pearlite appearance, and isolated block like
distribution of carbides in the cast state; The hardness reaches
HRC65 degrees and has a high impact toughness.
2. During the production process of roller sleeves, heat treatment
methods are used to achieve good crack resistance;
3. Smooth and smooth, with excellent workmanship and smooth
surface, which is beneficial for improving grinding efficiency
4. Each product undergoes professional flaw detection and reliable
quality testing before leaving the factory
5. Convenient maintenance and repair
Reduce costs, improve production and inspection efficiency, and
ensure the quality of factory products.
(6) Casting high chromium roller sleeve Cr20 with metal mold can
reduce the addition of precious alloy elements and reduce
production costs.
(7) For vertical grinding roller sleeves that cannot undergo
conventional heat treatment, metal mold casting can be used to meet
the usage requirements in the as-cast state.
(8) The cooling rate of metal casting is fast, which can refine the
structure. In addition, utilizing the characteristics of
solidification forming of the high chromium roller sleeve of the
vertical mill, the high-temperature castings can be air-cooled
(quenched), followed by insulation treatment at low temperatures to
reduce the internal stress of the high chromium roller sleeve of
the vertical mill. This not only saves energy, but also enables the
production of wear-resistant, corrosion-resistant, and ductile
castings that can be directly applied in the as-cast state.
The vertical grinding high chromium roller sleeve produced by Hefei
Hengcheng Technology has the characteristics of good crack
resistance, good wear resistance, high hardness, and strong
load-bearing capacity.
Vertical mill high chromium roller sleeve manufacturers have a
unique aspect in casting materials, which not only overcomes the
shortcomings of ordinary vertical mill roller sleeves such as non
wear resistance, short service life, and easy cracking. High
chromium roller sleeves have advantages such as good wear
resistance, high hardness, long service life, and strong
load-bearing capacity. It also has better hardenability than
traditional materials, lower cost, high output per unit time, and
increased economic benefits.
Hefei Hengcheng Technology castings use high chromium cast iron
wear-resistant materials, which have more stable product quality,
longer service life, and wide applicability. The quality and
cost-effectiveness of the products have reached a high level in
China. Different from other types of roller sleeves produced, the
wear surface is generally uniform and smooth, without any pits or
grooves. After long-term operation, there are no phenomena such as
detachment, cracks, or cracking.
