How to choose the quality of heavy-duty tire chains?

As a key component of the chain connection, the quality of the connector is directly related to the operational reliability and safety of the entire chain system. Whether it is mining heavy-duty tire protection chains, tractor tire chains, snow chains, or other types of tire chains. So, how to accurately determine the quality of the tire chains?

Firstly, raw materials are the cornerstone that determines product quality. High quality tire chains components must be made of high-strength and high-density alloy steel, which contains alloy elements such as chromium and manganese in precise proportions. At the same time, Tongwei use the equipment such as spectrometers to detect material composition and ensure that the alloy content meets the standard. State owned cooperative partners will be selected to ensure the quality of raw materials; The purer the steel, the better. Steel with fewer impurities is stronger and less likely to break under stress.

Our factory uses a metallographic microscope to examine the microstructure of the steel. If the alloy distribution is uniform, it indicates good quality and the entire chain will not break locally under stress;Each link and side ring of the chain must be made of the same high-quality steel, without any hardness or softness. Otherwise, with a strong force, the weakest one will break first, and the entire chain will be useless;

TONGWEI strictly controls the selection of raw materials and establishes long-term strategic partnerships with top suppliers in the industry to ensure that the purchased alloy steel materials have key indicators such as chemical composition, purity, and organizational uniformity that are superior to conventional industry standards.

In the hot processing stage, the company is equipped with an intelligent forging production line, which achieves precise temperature management throughout the forging process through a precision temperature control system. From the initial forging temperature to the final forging temperature, the process specifications are strictly followed to obtain the ideal metal fiber flow distribution, significantly improving the structural integrity and service reliability of the chain connector.

In the critical post-processing process, the enterprise has equipped itself with an internationally advanced online monitoring system for welding quality and an intelligent control device for heat treatment process parameters. Using digital non-destructive testing technology to conduct 100% quality screening of welded joints, ensuring that all welds meet Class 1 acceptance standards.

At the same time, by optimizing the heat treatment process window through big data analysis, the product achieves optimal matching in key performance indicators such as hardness and toughness, thereby endowing the tire protection chain with better service life and adaptability to working conditions.
