Innovative Casting Techniques for Mining Machinery
Casting, as one of the fundamental processes of industrial manufacturing, enables the production of large and complex parts of mining machinery. Due to the ability to form molten metal in a mold, heavy and integral parts such as mill shells, large shafts and rock crusher blocks are produced. For example, today’s advanced die casting methods are able to produce parts with complex shapes, precise dimensions, suitable surface finishes and high strength. For more than three decades, Sepahan Foolad Atashgah Foundry Industries Company has been able to produce thousands of key parts for the mining and steel industries in accordance with global standards, relying on advanced technologies and quality control systems. This history demonstrates the pivotal role of casting in the mining machinery industry and simultaneously highlights the urgent need for Innovative Casting Techniques Shaping the future of high-quality industrial components.
Traditional challenges in mineral casting
Traditional casting methods face challenges such as poor melt flow control, high defect rates (such as porosity and cold cracking), and trial-and-error mold design processes. Lack of accurate simulation results in long production cycles and increased material waste. Also, in large mineral parts (such as crusher shells or mill liners), phenomena such as uneven shrinkage, inhomogeneous solidification, and internal stresses affect the final quality. In short, traditional production often results in high cost, long lead times, and short part service life due to the lack of optimal mold design and accurate process control. Resolving these problems requires the use of new design methods, advanced materials, and Innovative Casting Techniques Shaping modern production standards.
New casting technologies in the world
Investment casting:
This method involves making a refractory mold by covering “lost” wax models and pouring molten metal. Its main advantage is the ability to produce metal parts with very complex geometry and high dimensional accuracy. Manufacturers use precision casting to form high-melting-point alloys (such as alloy steels and ductile irons) in complex molds. The waxing and gradual burning process of the pattern eliminates the need for extensive machining and produces parts with smooth surfaces and uniform mechanical properties, demonstrating the benefits of Innovative Casting Techniques Shaping advanced industrial parts.
Vacuum Die Casting:
In this method, air and gases are removed by a vacuum system before the molten metal is injected into the mold. This prevents the formation of gas bubbles and oxidation and minimizes melt turbulence. As a result, the process produces parts with excellent surface finish, high dimensional stability, and greater mechanical strength; it also shortens the production cycle time and minimizes gas defects. This technology is especially important in the production of thin and defect-sensitive parts and reflects the ongoing impact of Innovative Casting Techniques Shaping high-precision manufacturing.
Casting Process Simulation (CAD/CAE):
The use of computer-aided design and simulation (CAD/CAE) software allows for virtual study of melt flow, heat distribution, and solidification before the actual mold is built. Using simulation in the engineering stages enables designers to optimize the location of sprues, marks, and feed points, and avoid costly mistakes. According to experts, the development of CAD/CAE and integrated simulation methods in recent decades has significantly increased the quality of cast parts and reduced production cycles.
3D Printing Sand Mold:
The integration of 3D printing technology with traditional casting has revolutionized the manufacturing of complex molds. The ability to quickly produce custom sand molds with non-standard geometric shapes greatly reduces design time and production costs. According to additive manufacturing experts, “the ability to create custom molds with complex designs through 3D printing has revolutionized the casting process.” This method is particularly useful for rapid prototyping, producing highly detailed one-piece parts, and reducing product development time.
Smart and nanoscale alloys in casting:
New metallurgical trends focus on improving properties by modifying the microstructure. For example, researchers have succeeded in significantly enhancing the strength and hardness of aluminum and magnesium alloys by adding ceramic nanoparticles. Although it is difficult to disperse nanoparticles uniformly in the melt, the use of methods such as ultrasonic pulses in recent research has been able to reduce dispersion problems. These nanostructured alloys, while increasing wear and fatigue resistance, reduce part weight, and improve the overall efficiency of mining machinery. As research into ‘smart materials’ advances, experts expect that equipment with environmental responsiveness and internal monitoring capabilities (such as nanosensors) will enter the foundry industry in the future.
Implementation of modern techniques at Sepahan Foolad Atashgah
With over 30 years of experience, Sepahan Foolad Atashgah Company optimizes its production systems by utilizing advanced technologies. According to the company’s statement, one of their key policies is “using the latest technology, equipment, and technical knowledge available to improve the quality of products.” Accordingly, Sepahan Foolad Atashgah uses engineering simulation and CAD/CAE tools in mold design and casting processes to minimize production defects and ensure the quality of parts. The company also automates its casting lines as much as possible and implements digital quality control systems throughout the process.
Its 4 specialized laboratories (chemical, metallographic, mechanical properties, and NDT) enable engineers to closely monitor raw materials, semi-finished, and finished parts and measure important quality and safety parameters. In the field of materials, the company is working on the development of superhard and wear-resistant alloys. For example, Sepahan Atashgah has a track record in producing anti-wear manganese steels, which are used in mining wear parts. The company’s research and development department, in collaboration with universities and research institutes, pursues projects such as simulating new materials and improving chemical composition to continuously improve casting technology. The organization’s mission is also based on “producing and supplying high-quality castings” for the steel, mining and other industries, which is a step towards industrial self-sufficiency and developing the country’s exports.
Benefits of Innovations in the Production of Key Mining Parts
Implementing new casting techniques brings numerous benefits to the production of key mining machinery parts. Optimizing mold design and predicting melt behavior reduces defects such as porosity and stress in bulky parts (such as mill shells and crusher bodies). The use of advanced alloys and precise thermal control increases the hardness and wear resistance of components such as AG/SAG mill liners and rock crusher blades. As a result, the service life of these components is significantly increased. For example, Sepahan Foolad Atashgah is a leader in the production of ball mill liners (AG/SAG) and has succeeded in improving their durability by using modern casting.
Also, the production of high-quality cast iron balls (with precise spherical characteristics and uniform strength) reduces the maintenance costs of mills and increases their crushing efficiency. Sepahan Foolad Atashgah also uses modern technologies such as vacuum die casting to manufacture lighter but stronger components (for example, metal shells of mineral pumps or sensitive parts of gearboxes), which increases dimensional accuracy and reduces production energy consumption. In short, the above innovations lead to reduced production cycles, improved component quality, and significant cost and time savings for projects.
