High Chromium Cast Iron Solution

Process development process:

Demand analysis and material selection: The team first had in-depth communication with the customer to understand the working conditions and equipment wear of the concrete mixing plant. Combined with the needs, it was determined to use high-chromium cast iron as the main material, because high-chromium cast iron has excellent wear resistance and good impact resistance, and can effectively cope with the high-intensity wear of concrete and sand and gravel.

Alloy formula design: According to the use environment of the concrete mixing plant, engineers optimized the alloy formula of high-chromium cast iron, and enhanced the wear resistance and hardness of the casting by adjusting the ratio of chromium, carbon, molybdenum and other elements. At the same time, considering the impact resistance of the casting under high-intensity work, the matrix structure was further optimized to ensure that it has sufficient toughness while meeting the wear resistance requirements.

Manufacturing process development: During the manufacturing process, the imported DISA vertical line process is used to strictly control the casting temperature and cooling rate to prevent thermal cracks and pores in the castings, ensuring that the internal structure of the castings is dense and the performance is stable. In addition, after the castings are manufactured, they are quenched and tempered to optimize their microstructure and further improve their wear resistance and service life.

Performance testing and adjustment: The produced castings have undergone a number of rigorous performance tests, including hardness testing, wear resistance testing, impact toughness testing and usage simulation experiments. Test results show that these high-chromium cast iron castings perform well in the high-wear environment of concrete mixing stations, with significantly improved wear resistance and a service life that is more than 30% longer than that of traditional materials. Based on the test data, the team fine-tuned the manufacturing process to ensure product consistency and reliability.

Application and customer feedback:

High chromium cast iron wear-resistant castings have been successfully used in customers' concrete mixing plants. The frequency of replacement of mixing blades and liners has been greatly reduced, and the downtime of the equipment has been reduced. Customer feedback shows that this product not only improves the efficiency of the equipment, but also significantly reduces operating costs.
