High Chromium Cast Iron Wear Resistant Liner Board

High Chromium Cast Iron Wear Resistant Liner Board

In the fields of mining, cement, electric power, metallurgy and other heavy industries, equipment such as crushers, ball mills and conveyor systems are often in harsh working conditions of high-intensity friction, impact and corrosion. The inner liner of the equipment, as a key protective component, directly determines the service life, operation efficiency and comprehensive production cost of the equipment. The High Chromium Cast Iron Wear Resistant Liner Board, as a high-performance wear-resistant product carefully developed for extreme wear conditions, relies on its excellent material properties and scientific structural design to become the preferred lining solution for major industrial enterprises to improve equipment reliability and reduce maintenance costs.
The core advantage of High Chromium Cast Iron Wear Resistant Liner Board lies in its high-quality material formula and advanced heat treatment process. We adopt high-chromium alloy raw materials with a chromium content of 15%-30%, and properly add molybdenum (Mo), nickel (Ni) and other alloying elements to optimize the material structure, so that the liner board forms a uniform and dense (Fe, Cr)₇C₃ carbide phase during the casting process. This special carbide has extremely high hardness, up to HV1200-1600, which is much higher than the hardness of common mineral abrasives and traditional cementite carbides, laying a solid foundation for the super wear resistance of the product. After high-temperature quenching and low-temperature tempering treatment, the liner board obtains an ideal structure of martensite matrix + carbide, which not only ensures ultra-high hardness (up to HRC60-65), but also balances toughness, effectively avoiding brittle fracture under medium impact conditions, and adapting to the complex working environment of alternating wear and impact in industrial production.

Products Description

 

 

Compared with traditional manganese steel, low-chromium alloy and other liner products, High Chromium Cast Iron Wear Resistant Liner Board has obvious performance advantages. Under the same working conditions, its wear resistance is more than 10 times that of ordinary steel, 4 times that of high manganese steel liner and 2 times that of low chromium alloy steel liner, which can significantly extend the service life of the liner board to 3-18 months according to different working conditions. At the same time, the high chromium content endows the product with good oxidation and corrosion resistance, which can resist the erosion of corrosive media in the production process, and is suitable for harsh working environments such as high temperature (≤600℃) and humidity. In terms of economic benefits, although the unit price of High Chromium Cast Iron Wear Resistant Liner Board is slightly higher, its ultra-long service life can greatly reduce the frequency of liner replacement, reduce maintenance man-hours and downtime losses, and ultimately reduce the comprehensive production cost of enterprises, realizing the goal of cost saving and efficiency increase.

We adhere to the concept of customer-oriented and scenario-adaptive, and provide flexible customization services for High Chromium Cast Iron Wear Resistant Liner Board. According to the actual needs of customers' equipment models, working conditions (material hardness, impact intensity, temperature, etc.), we can customize liner boards of different thicknesses (20-100mm), shapes and specifications, and even optimize the design scheme according to the specific working conditions of customers to ensure that the liner board can be perfectly matched with the equipment and play the best protective effect. In terms of installation, we provide three convenient installation methods: bolt fixing, inlay type and welding type (needing special welding materials). The bolt fixing type is easy to disassemble and maintain, the inlay type can form mechanical interlock with the equipment matrix, and the welding type is firm and reliable, which can meet the installation needs of different equipment and working scenarios. In addition, our products comply with international standards such as AS 2027, ASTM A532 and BS 4844, ensuring stable product quality and wide applicability in the global market.

01

Excellent wear resistance:

The alloy layer has a carbon content of about 4% for ultra-high hardness, with wear resistance more than twice that of traditional cast alloys, greatly extending equipment service life and reducing replacement frequency.

02

Strong impact resistance:

Adopts a bimetal structure, combining the superior wear resistance of the alloy layer with the high load-bearing capacity of the low-carbon/low-alloy steel base layer; stably withstands impact and wear in material handling systems, and is not easily damaged even under high-intensity operation.

03

Outstanding heat resistance:

Operates stably at temperatures below 600°C; the high-temperature resistance can be upgraded to 800°C by adding vanadium/molybdenum, with synchronous improvement in wear resistance, suitable for high-temperature and harsh working conditions.

04

Scientific structural design:

The bimetal composite structure balances wear resistance and load-bearing capacity perfectly, adapting to the complex operation requirements of various material handling systems with high operational stability.
