After testing basic aspects such as the microstructure and impact abrasion weight loss, trial products were then mounted on actual machines for evaluation.
These tests revealed that 1.5C-18Mn-Cr high-manganese cast steel, and high-chromium cast iron with Cr/C =7,had excellent performance, extending the wear life of crusher parts.
In some cases, requirements cannot be satisfied simply by changing the material,and for these cases various composite methods were developed using low-alloy cast steel as the base metal with high-speed tool steel on the wearing surface, and using high-chromium cast iron as the base metal with cemented carbide on the wearing surface.
The composite parts were evaluated by testing them on actual machines, and it was confirmed that a drastic increase in wear life was attained as compared with single-material parts. The composites were then mounted on crushing machines used to crush bulky solid waste,and on crushers used for particularly hard materials. These achieved an extension of parts life and reduced machine maintenance costs.
Niobium, like titanium and vanadium, forms superhard MC carbides that remain relatively pure in technical alloys on account of their low solubility for other metallic alloying elements. However, because they have a greater hardness than the precipitated chromium carbides commonly used in wear‐resistant alloys, they are suitable as alternative hard phases. This contribution deals with new wear‐resistant steels and casting alloys containing niobium carbide. These include a secondary hardening hardfacing alloy, a composite

Sustainable development has become an urgent need. Especially for foundry, foundry in our country is a traditional basic industry, at the same time, it is also a high investment, high consumption and high pollution industry.
The trend of "three highs" in foundry industry has prompted the industry to seek a new development mode-green management.
We have rich experience in the production of steel castings, steel ingots and other products, and the steel castings provided by the company are recognized by our customers. Many customers are very interested in how to improve the density of steel castings. We will simply summarize the knowledge of the density of steel castings for you.
1. If the density of steel castings is high, casting defects such as bubble cracks and the like will not occur, thus reducing the rejection rate of products.
2. High density steel castings are suitable for use as precision steel castings, and the steel structure of steel castings will be more accurate.
3. The density of steel castings has a great influence on toughness. The higher the density of steel castings, the higher the toughness.
Iron castings are obtained through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, thus obtaining higher strength than carbon steel.
With the rapid development of the metallurgical and mining industry market in recent years and the increasing demand for energy conservation and consumption reduction, wear resistant castings with high technical content will usher in a spring of developme...
