Slurry pump manufacturers and their parts processors face a critical decision when selecting mechanical cutting tools. This choice is primarily based on the fundamental performance characteristics of the pumps, which are designed to handle high-resistance fluid paths ideal for transporting abrasive or corrosive slurries. These pumps are widely used in industries such as mining, metallurgy, oil, coal, transportation, power, construction materials, and municipal engineering for tasks like mining, dredging, transporting tailings, concentrating sand, ash, sludge, and iron. Currently, most wear-resistant components of domestic slurry pumps are made from high-chromium cast iron. This material has a hardness of up to HRC 65 and is considered one of the best wear-resistant materials available. However, its production involves complex processes and significant alloy content. Since the 1980s, it has been widely used in China, especially in the 1990s. Machining this material typically requires cemented carbide cutting tools, which lead to a complicated process, high costs, and low efficiency. The difficulty in machining high-chromium cast iron has long been a challenge for many manufacturers. Ceramic cutting tools represent a modern advancement in metal-cutting technology. They offer high hardness, strength, red hardness, wear resistance, excellent chemical stability, and a low friction coefficient. These tools can machine hard-to-process superhard materials that traditional tools cannot handle, while also improving productivity. Several slurry pump manufacturers have successfully adopted ceramic tools, proving their effectiveness in solving the machining challenges of high-chromium cast iron. This not only reduces production costs but also significantly boosts efficiency. Wear parts of slurry pumps typically include components such as the casing (worm wheel), guard (front and rear), impeller, secondary impeller, and vacuum cap. A detailed analysis of the machining process for these parts shows two main approaches: 1. **Traditional Tool Machining Process**: Casting – Annealing – Cutting – Quenching This method involves two heat treatments, leading to a long production cycle and higher costs. For parts like the guard plate and casing, they cannot be machined directly before annealing, requiring low-speed cutting and resulting in low efficiency. 2. **Ceramic Tool Machining Process**: Casting – Cutting This approach eliminates the need for two heat treatments, reducing energy costs and shortening the production cycle. With ceramic tools, roughing and finishing can be done directly after annealing, saving energy and enabling high-speed cutting, which greatly improves productivity. It also allows for lower equipment requirements or higher output with the same equipment. Despite the growing number of domestic manufacturers producing ceramic cutting tools, there is a wide range of materials and performance levels. Choosing the right ceramic tool for machining high-chromium cast iron is crucial. Improper selection can hinder the adoption of ceramic tools, disrupt production, and damage confidence in their use. Companies that have previously relied on conventional tools may struggle to transition effectively, potentially impacting their long-term development.
