Technical Field
The utility model belongs to the technical field of double-geared roller crushers, and particularly relates to a split type high-speed steel tooth head for a double-geared roller crusher.
Background
In recent years, along with the continuous improvement of the industrialization rate of the mining in China, the double-geared roller crusher is rapidly popularized due to the advantages of large treatment capacity, regular product appearance and the like, wherein the detachable toothed head structure is low in maintenance cost and high in maintenance efficiency, and is widely applied to various mine production enterprises.
As a material with high hardness, high heat resistance and high wear resistance, the material performance of the high-speed steel is very suitable for an ore crushing process, and more crusher manufacturers begin to use the high-speed steel to replace the traditional manganese steel to manufacture the crusher tooth heads. However, the traditional integral high-speed steel tooth head has certain defects, although the hardness of the high-speed steel subjected to heat treatment is high, the toughness of the high-speed steel is poor, the tooth root part is easy to break under the strong impact working condition of ore crushing, the weldability of high-speed steel is poor, and the high-speed steel cannot be repaired by using the traditional welding method, so that once the tooth head is broken, the tooth head can only be replaced in a whole manner, and the use cost of equipment is greatly improved.
