Harvester Wheel Wearable Materials

Harvester Wheel Wearable materials

High chromium cast iron is a high chromium white mouth anti-wear cast iron referred to, is a good performance and special attention to the anti-wear materials. It is much higher than the alloy steel wear resistance, and much higher than the general white cast iron toughness, strength, while it also has good resistance to high temperature and corrosion resistance, combined with convenient production, cost is moderate, and was Known as one of the best anti-abrasive wear materials.

High-chromium cast iron is one of the most important wear-resistant materials for a variety of high-stress abrasive wear conditions, widely used in machinery, metallurgy, mining and mineral processing industries. In recent years, industrial countries have attached great importance to the research work of high chromium cast iron, with a view to making full use of its excellent wear resistance.

 High-chromium cast iron is already recognized as a good wear-resistant materials, mining, cement, electricity, road machinery, refractories and other aspects of a wide range of applications. This is because the organization of high-chromium cast iron is composed of tough matrix and hard spots, hard points highlight the working surface, bear the main task of resistance to wear, the matrix structure is to provide support and protection of hard spots, so high chromium Cast iron than the general wear-resistant materials, good toughness, high wear resistance. High chromium cast iron through heat treatment, can change the shape and distribution of carbides, and refine the matrix structure, in order to obtain the desired mechanical properties.

On the high-chromium cast iron processing characteristics are as follows:

(1) high chromium cast iron low thermal conductivity, poor plasticity, shrinkage, and casting performance is poor, in the casting should pay attention to the casting of the problem.

(2) shape should be a good transparency of the sand, paint should be used with high refractory magnesium or aluminum powder.

(3) the specific parts of the casting, it should be noted that casting can not be blocked phenomenon.

(4) pouring temperature is low.

(5) high-chromium cast iron riser is not easy to remove, in the shape of the use of riser on the side of the riser or easy to cut riser.
