Analyzing on the Reasonable Composition of High-Chromium Alloy Cast Iron to Make the Mud Pump Shell of Dredger

Abstract:

Chose high-chromium cast iron as the material to make the mud pump shell, the composition of high-chromium alloy has been optimized and five kinds of alloy ( A, B, C, D and E) are designed. Furthermore, using the heat treatment method of air-cooled quenching of 1040°C + 260°C tempering, the relationship among material hardness, the impact toughness and the heating temperature is analyzed after heat treatment. Finally, the abrasion performance of wear-resistant materials is tested. The test result shows that all kinds of wear-resistant materials display well anti-abrasion performance, where the material E has the best relative wear resistance and 19.3% higher than the imported pump casing material. The results provide a scientific standard for selecting the practical wear-resistant materials and locating the piece casting bivalve pump of Cr26 high-chromium cast iron.
