Product Description:
High boron steel roll is a high-performance roll material with high hardness and excellent wear resistance. It plays a significant role in stabilizing the rolling process, improving the level of negative control, increasing the overall rate of finished products, increasing production capacity and reducing process costs and other indicators, and is cost-effective in bar production line applications.
High Boron Steel Rolls organisation contains a large number of boron carbide, so that it has a high hardness, excellent wear resistance, high temperature stability, and lower production costs.
Product Performance:
High Boron Steel Rolls manufacturing centrifugal composite casting process, roll structure for the three-layer composite, the working layer of high boron high-speed steel materials, in order to prevent the boron element in the outer layer into the core and reduce the use of its performance, in the roll body of the working layer (High Boron Steel Rolls) and the core (ductile iron) to join the transition between the layer (ductile iron).
The hardness of high boron steel rolls is usually in HS75-80, and the hardness of its wear-resistant layer can be even higher, providing excellent wear resistance. The service life of these rolls is many times that of conventional rolls, contributing to increased productivity and reduced maintenance costs.
Product Advantage:
We produce High Boron Steel Rolls with compact structure, high toughness, good abrasion and impact resistance, which are not easy to produce pockmarks and meat loss in the process of use, so as to achieve the purpose of improving the service life of the rolls and reducing the production cost of the plant.
In terms of the manufacturing process, the smelting and casting processes for high boron steel rolls require precise control to ensure the material's performance. For example, the smelting process may require melting of low alloy HSS molten steel in an electric furnace, followed by alloying with ferro-vanadium and some ferro-boron during the process of removing from the furnace, addition of some ferro-boron and composite modifiers in the casting ladle, and addition of vanadium and nitrogen alloys, zirconium ferro-silicon, ferro-silicon and some ferro-boron particles in the flow during the casting process.
In addition, heat treatment of high boron steel rolls is an important step in improving their properties. The heat treatment regime may include heating, holding, and cooling processes to form the desired microstructure and hardness.
In terms of machine tool machining techniques, due to the high hardness of the high boron steel rolls, it is necessary to select appropriate cutting tools and parameters. For example, machining with CBN tools may be required to improve machining efficiency and extend tool life.
Overall, high boron steel rolls are widely used in the steel industry due to their excellent performance, especially in applications requiring high wear resistance and long service life.
