DC11 steel plate makes knife in belt breaker

1, Overview of DC11 steel
DC11 steel is a steel grade manufactured by DaiDo (Japan) under JIS standards. DC11 steel is a premium grade steel used in cold stamping dies with excellent quality. DC11 steel has the following outstanding mechanical properties:
- Details can withstand high abrasion, excellent toughness at normal temperatures;
- Good mine permeability, mine stress is lowest;
- Improve performance and extend product life;
- Smooth, fine cutting machining surface;
- Hardness after heat treatment (vacuum annealing) reaches a perfect level of 60HRC - 62HRC;
- Can work continuously in continuous stamping conditions, high load or large impact force, ...
So from the above, DC11 steel sheet is used as a knife to break the belt like?
2, DC11 steel as knife in belt breaker
On the market today, the vertical or horizontal belt breakers mostly use SKD11 solid steel as a cutting knife. Depending on the machine model and the manufacturer's design, the tool will also have different shapes and sizes.
This difference is also one of the causes of knife breakage problems because of inconsistent knife structure or insufficient thickness of the tool to ensure durability during machine operation. So some manufacturing units have improved the cutter set and machine structure to use the sheet type to increase the stability of the knife set. At that time, the material used to make the best knife that could replace SKD11 solid steel was the DC11 steel plate.
Thanks to the outstanding mechanical properties of DC11 steel and the common specifications of DC11 steel, it has met the requirements of the knife breaker. After machining, the set of knives will be tempered to hardness 58HRC - 60HRC instead of from 55HRC - 57HRC as with solid steel SKD11. Because the mechanical properties of DC11 steel can reach hardness up to 60HRC - 62HRC after quenching but can still work effectively with high ductility, excellent abrasion resistance and strong impact force during cutting. Therefore, the use of DC11 sheet steel as a belt breaker is the perfect choice and cannot be better.
3, Advantages of DC11 steel as a knife in the belt breaker
DC11 steel is a high-class product line of DaiDo (Japan), the initial hardness and ductility are very uniform, so the steel is easy to process, saving time and tool cost.
The product has little deformation after heat treatment, uniform hardness at all points. After heat treatment, the hardness can reach ≥ 60HRC making the knife very hard, minimizing the abrasion or deformation but the mechanical and ductility of the steel is not affected. So the knife set will be very durable and limit cracking and cutting.
High tool life and durability help extend the service life, ensure productivity, save machining costs and replace knives many times when using unqualified materials.
