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.
