High chromium cast iron slurry pump castings | EPC, hard core guards every inch of wear front!In the depths of the mine, the roaring workshop of the concentrator and the end of the tailings conveying pipeline, there is a working condition that is more scorching than high temperature and more destructive than high pressure-that is, the continuous scouring of high-concentration and highly abrasive slag slurry. Here, ordinary metals "flinch", only high chromium cast iron, with extraordinary hardness and wear resistance, has become the ultimate line of defense against wear. And we forge this "industrial armor" by EPC precision casting process-to create a core casting with real long life, high reliability and high efficiency for the slurry pump! Why do high-end slurry pumps choose our high-chromium cast iron EPC castings? Hard core material: Cr15Mo3/Cr26/Cr28, with hardness reaching HRC58-65. We use high-quality high-chromium white cast iron (such as Cr15Mo3, Cr26, Cr28, etc.), and the carbides are M₇C₃-type with dispersed distribution, and the hardness is far higher than that of ordinary cast iron and alloy steel. Under the impact of strong abrasive particles, it still maintains excellent wear resistance, and its service life can reach 3-5 times that of ordinary castings! Technological innovation: lost foam casting, one-step molding of complex runner The inner cavity structure of slurry pump shell, guard plate, impeller and other parts is complex, and the traditional sand mold is prone to problems such as sand inclusion, sand sticking and size deviation. And EPC (Lost Foam Process) uses the vaporizable foam model to realize: No parting surface, no draft angle, and the runner is smooth as a mirror. The wall thickness is uniform, the contour is accurate, and the hydraulic efficiency is improved by more than 10%. Near-net forming, greatly reducing the machining loss of expensive high chromium materials Dense structure: vacuum negative pressure casting to prevent porosity. The solidification shrinkage of high chromium cast iron is large, and it is easy to produce internal defects. Through vacuum sealing molding+directional solidification control, combined with strict melting degassing and fine-tuning of components, we ensure that there are no shrinkage cavities, pores and inclusions in the casting, and it will never be "make a fool of oneself" even under the impact of high-pressure slag slurry. Green and efficient: less pollution, high yield and quick delivery. The lost foam does not need binder sand, with less waste and low dust; The model can be numerically controlled and the development cycle is short. From drawings to finished products, proofing takes 7 days and batch takes 30 days to help you respond to project requirements quickly! Typical application scenarios Grinding and classification system of concentrator Thermal power generation desulfurization gypsum transportation Pressurized transportation of coal water slurry Tailings backfilling and long-distance pipeline transportation High wear slurry circulation system in metallurgy and chemical industry No matter AH type, ZJ type, SP series or non-standard customized pump type, we can provide complete sets of high chromium cast iron castings such as pump casing, front guard plate, rear guard plate, impeller and suction cover. We are not casting parts, but "the terminator of downtime" Every time the pump parts are replaced, it means that the production line is stagnant, the cost is soaring and the efficiency is lost. And choosing our high chromium cast iron EPC casting is to choose: Longer continuous operation cycle Lower spare parts inventory pressure Higher system comprehensive benefit Let wear and tear no longer become the bottleneck of production, and let efficiency continue to flow in hardness! High Chromium Cast Iron × EPC Process = "Golden Combination" of Wear-resistant Castings We use science and technology to cast a wear-resistant shield and keep the pulse of industry with ingenuity. Contact immediately to get the material report, wear test data and free sample! Hard-core castings, choose us-let the slurry pump become stronger and stronger in tempering!
