How We Produce Tool Steel
The diagram below illustrates the production process of forged tool steel. Our production mainly focuses on providing high-quality forged round bars and plates. The process begins with melting and refining the raw materials, casting, and optional remelting for improved purity. The forged steel is then shaped, annealed for better machinability, and processed to remove the oxide scale. Finally, surface finishing is applied to ensure the desired quality and appearance.
This image shows an Electroslag Remelting (ESR) machine in operation. ESR is a specialized process used to improve the purity and quality of steel. During this process, a pre-cast ingot is remelted under a layer of molten slag, which acts as a purifier by removing impurities and inclusions. The refined steel solidifies as it cools, resulting in a material with a uniform structure, enhanced mechanical properties, and superior surface quality. This process is essential for producing high-performance tool steels and other critical materials.
In this video, you can see the forging process of a heated tool steel ingot. After being heated to the required temperature, the tool steel ingot is placed under a mechanical press. The forging press applies immense pressure to shape the steel into the desired form, enhancing its internal structure and mechanical properties. This process eliminates internal defects, refines the grain structure, and improves the material’s strength and durability, making it ideal for high-performance applications.
This video showcases a centerless grinding machine processing a tool steel round bar. In this operation, the round bar is precisely ground to achieve the required diameter and surface finish without needing a center to hold the material. This high-efficiency process ensures excellent dimensional accuracy, smooth surface quality, and consistent roundness, making the finished product suitable for demanding industrial applications.
