What type of steel should be used to make the belt breaker?

And one of the key parts in a belt breaker is a cutter (also called a belt breaker). In addition, the type of tool material required to meet the working frequency of the machine. Therefore, SKD11 solid steel as a knife in a breaker is often used by manufacturing units. To understand more about this material, let us find out soon.
1. Summary of belt breaking machine
The belt breaking machine was born to help make the formation of steel belts easier and faster than ever. With the ability to create different types of belts such as: Straightening, L-shaped belts, triangular belts, quadrilateral belts, pentagonal belts, ... Belt breaking speed reaches a speed of about 25m / min and output is reached. 3,000 products in a shift. With such working frequency, the parts of the machine must also work continuously with high intensity.
The breaker is basically structured with three main parts:
- Straightening set;
- Cutter;
- Hydraulic system.
In particular, the cutter is a component that works with a continuous frequency during operation, so the requirement is to ensure that the knife does not break or deform, wear resistance, cutting force, breaking force. biggest? What material would be best to make a knife? And the choice couldn't be any better than Japanese SKD11 steel.
2. SKD11 solid steel for making knives in belt breakers
With the requirement of continuous working, high abrasion resistance and impact force, the selection of a quality tool material is a prerequisite for the best set of knives.
As is known, SKD11 steel is a kind of steel with very good abrasion resistance, durability, ductility and resistance to deformation. In particular, SKD11 solid round steel is used to make shaped rolling shafts, slitting knives, punches, tooth shafts, large load gears, machine parts, precision parts, ... Therefore, the use of steel thickening SKD11 for making belt breakers is a better option.
As we all know in previous articles, carbon is the most important factor that determines the organization and properties of alloy steels in general and SKD11 steel in particular. Therefore, the carbon content in SKD11 steel accounts for about 1.5%, so the durability, stiffness, elasticity or impact resistance of SKD11 steel knives in belt breakers are very good.
In addition, in the chemical composition of SKD11, the addition of a large amount of Molybdenum (Mo) is about 1%, much higher than other steels, which makes the belt-breaking knives resistant to grinding. worn well.
Not only that, SKD11 steel also has other components such as Manganese (Mn), Silicon (Si), Chrom (Cr), ... all with equal effect between hardness and toughness for the knives, improve longevity or longer working time.
3. SKD11 steel heat treatment is an important stage
Thanks to the composition above, solid steel SKD11 as a knife in the belt breaker can heat anneal vacuum to hardness 58HRC - 60HRC. This is the second most important factor in creating a quality knife set. When the hardness is high, the cutter will work stably without being subjected to abrasion too quickly, avoiding the case of deformation under strong impact. In addition, the tool life is longer and the operation is more durable, providing the highest productivity and efficiency for the machine.
Above are two important factors to create the best quality knife breaker. In addition to using high quality steel such as Japanese SKD11 steel, the heat treatment process is a stage not to be missed.
Above is some information about SKD11 solid steel for making knives in the belt breaking machine in this article, which we would like to offer to our customers.
