Wear-resisting round link chains and slag dragging chain
Product Details
According to GB12718, DIN22252 standards and related industry standards.
use
Used in power plant slag removal machines, the slag extraction chain has two series of T-level and E-level, with multiple grades, suitable for high anti-wear, high wear-resistant working conditions and high anti-wear and high-strength working environment requirements. DIN22252, DIN764, GB/T12718 and other standards.
Technical characteristics
Breakdown distribution of T and E slag chains
There are differences in the operating conditions of the slag chain in actual use. We provide two different types of slag chains based on T-grade and E-grade. The hardness distribution has different differences. Under various working conditions, chains with different technical conditions should be selected.
Because the slag chain produced by Gelin has excellent willfulness, it has a very high tensile strength. At the same time, the surface layer has excellent wear resistance after being treated by special heat treatment.
Typically, as the hardness layer increases, the wear resistance also increases, but the breaking strength decreases. Gelin technical experts provide professional solutions, so that the chain has high wear resistance while still showing outstanding breaking strength, which ensures the reliable operation of the equipment. Especially suitable for high-power and high-efficiency bucket elevator transportation equipment.

Contains Cr, CrN or CrNiM. The alloy material has high purity and fine grains. During heat treatment, the carburizing process is used to obtain ultra-high hardness from the surface to the center of the chain to obtain ultra-high wear resistance.
T-class slag chain
Usage
For working environments with particularly high requirements for wear resistance.
The T-level slag chain is divided into T40 series of MnV series alloy steel and T80 series of CrNiMo high-quality alloy steel according to the alloy type; according to the depth of the effective hardened layer, it can be divided into three grades: K4, K6 and K8. Gelin has adopted containment manufacturing, and has undergone a special optimized heat treatment process to obtain a higher working load to meet the needs of the majority of users.

During the use of the slag chain, it is necessary to regularly test and analyze the breaking strength, fatigue strength, hardness distribution and wear resistance of the chain and related components.
Tolerance of the chain
1. The manufacturing tolerance of the standard length chain is +0.4%~-0.15%o, that is: the maximum tolerance is equal to 0.55% (the maximum allowable tolerance for a chain with a length of 10 meters is 55 mm).
2. The length tolerance of the paired chain: AX does not exceed 0.05%, that is, the maximum tolerance of two pairs of chains with a length of 10 meters is 5 mm.
When the paired chain length is less than 8 meters, the maximum pairing tolerance is 4 mm.
Slag ring chain
According to GB12718, DIN22252 standards and related industry standards.
use
It is used in working environments with general requirements for wear resistance. The slag ring chain is divided into MnV series and CrNiMo high-quality alloy steel according to the alloy type; according to the strength, it can be divided into B grade and C grade, and products of various specifications are available for the majority of users to choose.
