Pearlitic Ductile Iron Roll And Bainite Ductile Iron Roll Production

      Pearlitic ductile iron roll is a type of roller that has high strength, toughness, and wear resistance after heat treatment. This roller has a long service life, stable operation, high efficiency, and can improve the surface quality and dimensional accuracy of steel in production, effectively reducing mechanical and maintenance costs. In addition, Pearlitic ductile iron rolls also have advantages such as fatigue resistance and crack resistance, which can help steel enterprises reduce production costs and improve production quality, and enhance product market competitiveness. Bainite ductile iron roll is a roll with high hardness, high wear resistance and high thermal stability, which can meet the needs of high-speed rolling. Bainite roll has excellent rolling effect and long service life in steel production. This roller has the characteristics of high efficiency and energy conservation. While improving the surface quality and dimensional accuracy of steel, it can also reduce downtime and maintenance costs, helping enterprises reduce production costs and improve economic benefits. In a word, both pearlite rolls and Bainite ductile iron rolls are indispensable tools for iron and steel enterprises. By selecting roller types that are suitable for the needs of enterprises, production efficiency and economic benefits can be improved, and more social value can be created.

      Production process of SGP rolls
1. Mold design and manufacturing: Determine the shape, size, and other parameters of the roll mold, select suitable mold materials, use CAD or CAM software for design, add pearlite spheroidizing agent and inoculant to the mold material, and carry out mold manufacturing.
2. Melting: High quality blast furnace pig iron, scrap steel and other raw materials are selected for melting and heating, and pearlite spheroidizing agent and inoculant are added to spheroidize the iron liquid, forming pearlite ductile iron liquid.
3. Casting: By automatic or manual casting, the pearlite ductile iron liquid is injected into the casting mold, which is naturally solidified and cooled to form a rough ductile iron roller.
4. Heat treatment: Heat treat the nodular cast iron roller blank to ensure that its structure and performance meet the requirements.
5. Machining: Through machining processes such as turning, milling, and grinding, the pearlite ductile iron rollers are accurately processed to form the final product.

      Production process of SGA1 rolls
1. Mold design and manufacturing: Determine the shape, size, and other parameters of the roller mold, select suitable mold materials, use CAD or CAM software for design, add twinning elements of ductile iron to the mold material, and perform slag soaking and foaming treatment after the mold manufacturing is completed.
2. Smelting: high-quality blast furnace pig iron, scrap steel and other raw materials are used for melting and heating, and the spheroidizing agent and twin forming elements of nodular cast iron are added to make the molten iron form Bainite ductile iron liquid.
3. Casting: Bainite ductile iron liquid is injected into the casting mold by automatic or manual casting, and the rough roll of ductile iron is formed after natural solidification and cooling.
4. Heat treatment: Heat treat the nodular cast iron roller blank to ensure that its structure and performance meet the requirements.
5. Machining: After turning, milling, grinding and other machining processes, the Bainite ductile iron roll is accurately processed to form the final product.

      Advantages of SGA1 rolls
1. Good wear resistance: the dual structure of Bainite ductile iron Bainite and ductile iron matrix ensures its high wear resistance under high temperature and high pressure working environment.
2. Good corrosion resistance: the surface hardness of Bainite ductile iron roller is high, which has good corrosion resistance and is suitable for use under various working conditions.
3. Good processability: The Bainite ductile iron roll has good processability, can be processed by a variety of machining processes, and has high production efficiency.

      Pearlitic nodular cast iron roll and Bainite nodular cast iron roll are slightly different in production process and material composition, but both have their own advantages to meet the requirements of different industrial fields for roll performance. Both pearlitic ductile iron rolls and Bainite ductile iron rolls are high-quality metal products, which provide strong support for industrial development.
