Why is the thickness of the mining lifting chain uneven?

Some experienced mine workers will conduct an inspection before using a mining lifting chain. Such inspection can promptly discover possible problems with the chain, such as uneven thickness of the chain. So, why does the lifting chain used in the mine have uneven thickness?

If it is the first time that the mining lifting chain has uneven thickness, it may be that the purchaser has encountered a black-hearted manufacturer. These manufacturers may do things that are shoddy and shoddy, so the produced chain may be different in thickness. all. If the chain that has been used for a period of time has uneven thickness, it may be that the wrong operation during use has caused some chain links to be severely worn; or after the chain is broken, the user uses the chain links of other chains to weld on his own On the lifting chain used in the mine.

When purchasing mining lifting chains, mine purchasers not only need to save the purchase funds as much as possible, but also need to pay attention to ensuring that the chains are sufficiently safe and reliable, so as to avoid accidents. At the same time, users also need to be careful not to repair damaged chains at will, and to check before use to find problems in advance, so as to ensure work safety.

What are the types of mining chains?

Mining chains are mainly used for mining, with relatively high requirements and a large toughness coefficient. At present, domestic mining chains are divided into B grade, C grade and D grade according to the strength grade. The materials are 25MnV and 23MnCrNIMo54. It is divided into flat chain, reinforced chain and anti-corrosion chain:

The reinforced mine circular chain series adopts forged vertical rings and special heat treatment, which has high tensile strength, long fatigue life and high toughness of domestic chains, and the optimal hardness distribution of each ring reduces the chain ring. The wear and tear between them significantly increases the service life.

Anti-corrosion mine circular chains and compact chains, developed for corrosive working conditions, developed a special raw material for anti-corrosion chains.When the water on the ground of the coal mine is particularly corrosive, corrosion pits and fatigue cracks will occur in ordinary chains. The anticorrosive mining chain is almost not affected by corrosion.
