How are link chain made?

Link Chain are produced by small groups of equipment or units. These units include forming machines, welding machines, alignment machines and sometimes twisting machines. The former receives wire, stamps it with grade and tracking codes, and then cuts it to the approximate length required for the chain link. This part is formed as a link which interconnects with a previously formed link so that the links formed from the wire form a Link Chain.

The Link Chain is then passed to a welding machine, where each link is mechanically welded without filler by heating the edges of the wire ends and forging them together. Excess material is trimmed.

After the Link Chain is formed and welded, it is calibrated to ensure consistency in the length of each link. This process also tests the strength of the chain, focusing specifically on the welded parts.

Samples of welded chains cut multiple times from the production process are tested every shift to verify the integrity of the welds and check physical properties. Data from each test is stored electronically for future reference.

Some Link Chain are twisted and are used for cross chains in tire chains that come into contact with the road.

After the inspection is completed, the Link Chain will be loaded into the storage box and awaits the next step.

The next process step is determined by the grade of the Link Chain and the customer's special requirements. Some of the Link Chain will be sent to our quench and temper induction heat treater, where it will be heated to 1600 to 1700 degrees Fahrenheit, quenched in water, and then tempered at 400 to 600 degrees.

From here, the chain will automatically undergo verification testing to twice its workload limit. These Link Chains will be put into barrels or cut and assembled into many products, mainly drag and strapping chains and agricultural safety chains. Please note that all Link Chains must not be used with a load exceeding their rated working load limit and only alloy chains may be used for overhead lifting.

For other grades of Link Chain, such as inspection coils or high test chains, no heat treatment is required. Therefore, the next process after forming and welding will be packaging, shot blasting, hot-dip galvanizing, galvanizing or other special coatings. The finished welded Link Chain is packaged and ready for shipment, but is most likely just cut and assembled into various assembled products. The chain is then shipped to the customer ready for use or resale.

Characteristics and uses of link chains

The link chains is made of high quality stainless steel. As a common transmission product, it has obvious advantages compared with belt drive, and has the characteristics of high precision, fast use speed and good performance.

From the structure of the chain, it is just like a motorcycle chain: there are two types: roller chain and sleeve chain. Judging from the parts used on motorcycles, there are two types: those used inside the engine and those used outside the engine. A larger part of the chains used inside the engine are sleeve chains, while the chains used outside the engine are transmission chains used to drive the rear wheels, and most of them use roller chains. Therefore, we must take good care of these chains. Welding chains are widely used in food, chemical, pharmaceutical, printing and other machinery, and welding chain equipment now has equipment with excellent performance. It also has the characteristics of acid resistance, high temperature resistance, corrosion resistance, and long mechanical service life.

How is the Link Chain used in the construction industry?

Welded link chains are widely used in food, chemical, pharmaceutical, rubber, printing, wire cutting and other machinery, and are matched with various import and export machinery. It is an excellent piece of equipment in modern equipment. It is especially suitable for corrosion resistance, cleaning or some fields with high chemical requirements, as well as high and low temperature occasions. A welding chain is a friction-driven machine that transports materials in a continuous manner. Welded ring chains are widely used not only in the industrial field, but also in the construction industry.

430 stainless steel works equally well in cooler indoor environments. However, in both rural and urban areas, frequent cleaning is required in order to maintain its outdoor appearance. In heavily polluted industrial and coastal areas, dials may become dirty or even rusty. However, for the aesthetic effect of the outdoor environment, nickel-containing stainless steel mesh belts need to be used. In fact, welding chains are manufactured in completely standard hardware shapes and sizes, and there are many special shapes as well.

Welded link chain combines performance, appearance and usability as stainless steel continues to be one of the best building materials in the world. The requirements for the use of welded link chains are mostly to maintain the original appearance of the building for a long time. When specifying the type of stainless steel to be used, the main considerations are the aesthetic standards required, the corrosive nature of the local atmosphere and the cleaning policy to be adopted.

What are the specific requirements for storing welded Link Chain?

Storage of welded link chains is also critical to longevity. When these parts are not in use, they cannot be placed randomly, otherwise the quality of the welding chain will be easily damaged. Do not store these products in places with moisture, high temperatures, or chemical corrosion. Avoid storing it in a humid environment, because in a humid environment, the moisture and oxygen covering the surface of the self-strengthening chain will react chemically to form rust, which will damage the quality of the chain and affect sales.

With the development of the world economy, my country's welding chain industry is full of vitality. Many new changes have taken place in production development, product structure, technical quality, market development, and economic operations, and many new results have been achieved. While we have seen many achievements, my country's chain industry still has many problems such as insufficient brand effect, few high-end products, and difficulty in ensuring the quality of chain steel. my country's chain industry has relatively poor steel supply conditions and is basically in a seller's market. Although many companies have adopted diversified material selection methods, they are still limited in terms of price and specifications, and it is difficult to guarantee the inherent quality of steel.

The steel used in foreign chain manufacturing is matched by steel manufacturers according to requirements. Its composition, surface quality and geometric accuracy can all meet the requirements of use, providing an effective guarantee for the automation of chain product processing. This is why low-end products can be exported domestically, while high-end products need to be imported.

In the development of welding chains, in addition to the development of chain products and the emergence of new materials, the functions of welding chains have been enhanced, and the overall strength and stiffness have been improved. This is a huge boost. The electrical control system of the welding chain is equipped with high-precision, high-sensitivity, and high-reliability speed control, signal acquisition, signal transmission, and logic execution components, which enables rapid changes in the electrical control level of the welding chain. It makes it possible to implement some complex automated conveyor lines with logical network functions. At present, high-performance welding chains already have advanced functions such as fault self-diagnosis, fault level identification, and fuzzy intelligent control. The emerging fully digital welding chain is attracting attention from the welding chain industry.

A brief discussion on how to remove rust spots on the surface of link chains

To remove rust spots on the surface of the link chains, you can use pickling paste, which can improve the surface finish of the link chains. When using stainless steel, please apply pickling paste on the surface of the welding chain. The coating thickness is 0.5-2mm. The general reaction time is more than 3-10 minutes. When used below 0℃ or in places with thick oxide scale, the time needs to be appropriately extended. It is best to use the brush several times during the treatment. Good) rinse to avoid rust. If water comes out of the product, do not pour it out. Shake or stir well before use.

The friction between the chain plate and the conveyor belt is not enough to cause slipping, which may be caused by the absence of water or a humid environment. The solution is to add some rosin powder inside the drum. But be careful not to feed with your hands to avoid malfunction. If the initial tension is too small, the conveyor belt roller tension is not high, which usually occurs at startup. The solution is to adjust the chain plate tensioning device, lift the chain plate, and increase the initial tension.

When the stainless steel surface is contaminated with grease or lubricating oil, first wipe it clean with a soft cloth, and then clean it with a neutral detergent or ammonia solution.

When there is dust or dirt on the stainless steel surface, it can be washed with soap, weak detergent or requirements. The trademarks and films on the stainless steel surface should be cleaned with warm water or weak detergent, and the adhesive components should be cleaned with alcohol or organic solvents.

When stainless steel instant noodles become rusty, they can be cleaned with 10% nitric acid or abrasive detergent. The welding chain factory can use special cleaning agents. Therefore, if you want stainless steel to maintain a smooth surface and extend its service life, the stainless steel transmission chain must achieve the above points.

When rainbow patterns appear on the surface of stainless steel, it is caused by excessive use of detergent or oil. Use warm water and mild detergent when washing.
