Special Quenched and Tempered Spring Steel Belt For Saw Blades
Spring steels are used in components that are subjected to high stresses. They combine high strength, wear resistance and toughness. Typical applications include link plates, belt buckles, springs, steel caps for safety shoes, saw blades and knives.
The steel must be hardened and tempered to give it the required properties. This process involves heating the steel to its critical transformation temperature and then cooling it.
Strength
Stainless steel is a high-performance alloy that provides excellent strength and wear resistance. It is ideal for applications that require high stress and long life, such as chain straps, springs, steel caps for safety shoes, and saw blades. Its good toughness enables it to withstand bending, twisting, and cutting without deforming. The addition of aluminium and chromium enhances its resistance to corrosion. It also improves its machinability and high temperature non-scale performance.
Heat treatment is a thermal process that strengthens steel strips through controlled heating and cooling. The strip is heated to the critical transformation temperature of its grade, quenched, and then tempered in a tempering oven. The tempered strip is then ready for use in various industrial applications.
Waelzholz Brasmetal offers cold rolled martensite-hardened and tempered steel strip for wood band saw blades in different application-optimized Special quenched and tempered spring steel belt for saw blades grades. The material’s extreme flatness reduces both saw tooth wear and saw blade loss to a minimum. This is particularly crucial when working with extremely hard materials, such as marble and granite. It is also important for sawing tasks that demand absolute precision, such as stone window sills. These are clamped into special saws known as stone gang saws, and they must cut precisely so that they do not damage the rock beyond the kerf. The steel used for these saws must meet the following requirements:
Toughness
Unlike ordinary carbon steel, spring steel can be hardened and tempered without losing its resilience. This makes it more durable and suitable for a wide variety of applications. It can withstand considerable bending and twisting without losing its shape or strength. It is also less likely to rust or wear out than other types of metals.
The toughness of this type of steel can be further increased by using a process known as differential hardening. This involves heating the steel evenly to a red-hot temperature and then rapidly cooling it, which turns part of the steel into very hard martensite while the rest cools more slowly and becomes softer pearlite. This increases the toughness of the blade and prevents it from breaking under stress.
Another feature of this kind of steel that makes it very tough is that it has a perfectly straight edge. This ensures that the saw teeth attached to the material will produce a precise and clean cut every time. This is especially important for stone gang saws, which need to be able to cut through very thick and rough materials. A straight edge will also minimize the amount of stone dust that is produced during cutting. This Tinplate steel coils Manufacturer can help reduce the need for frequent cleaning and maintenance of the saws. This will save money and time in the long run.
Durability
When cutting through hard-to-cut metals, a carbide blade is the way to go. Carbide is an extremely durable material that resists heat, resulting in a longer blade life and increased performance. However, it’s important to note that the durability of a saw blade depends on several factors, including the type of machine used and the experience of the operator. A trained operator is more likely to use the proper cutting parameters, properly break-in the blade, and perform preventative machine maintenance.
Differential hardening is a technique used to heat treat swords and knives to make them resistant to breaking. It involves adding a heat insulator to the spine of the blade, such as clay. This allows the edge to cool faster than the rest of the blade, allowing it to reach high levels of hardness without making the whole blade brittle.
In the heat treatment of steel for metallurgical saw blade, the present invention adopts online or off-line quenching+tempering heat treatment technique and utilizes water medium to quench, which is beneficial to the protection of the operator’s healthy and the environment, is effective in the high-temperature non-scale and corrosion resistance, improves the machinability and hot workability, and makes the hardness of the saw blade even. Moreover, by using the appropriate chemical component design and coordinating it with suitable quenching mechanism, it can simplify again production technique, shorten the production process and save energy.
Flexibility
During the process of making special quenched and tempered spring steel belt for saw blades, it is important that the steel remains its shape. This can be achieved by heat treating the steel to a certain temperature, then quenching it quickly in some liquid. This hardens the steel, but it is still able to bend and retain its form. The next step is tempering the steel. This softens the steel, but it also increases its toughness.
This hardened and tempered steel is used in a variety of different applications, including saw blades, industrial knives, and automobile components. The flat springs for automobile clutches, safety seat belt buckles, and horn diaphragms are made of this material. It is also found in masonry and agricultral tools, gang saws for marble cutting, and band saws.
Carbide tipped saws are another type of band saw that requires exceptional durability. The backing for these blades is a flexible spring steel that allows it to bend and flex, which helps prevent the teeth from wearing down too fast. The carbide tip is electron-beam welded onto this backing, which is milled into teeth pockets. The result is a blade that cuts both marble and granite reliably without damaging the stone beyond the kerf. This high level of precision reduces both wear on the saw teeth and waste of high-quality stone materials.
