Technical Elements To Bucket Teeth Conjunction

There are many technical elements that effect the conjunction of bucket teeth. Such as drawings cooperation scale, coating and so on. Precise cooperation scale can ensure the bucket teeth cooperate closely. The metal has been shortened to 2%-3% freely. With the condition of sand hinder, shortening will be less than 2%. When you coating the bucket teeth, you should be very careful. Coating evenly and control the coating layer thickness of the sand mold and core strictly.

Tooth tip and tooth seat had better do heat treatment in the production process. Because the fallen oxide skin will affect the platform scale. Certainly due to the casting structure is not same, the casting shortening will be reduced after the molten steel poured into the mold casting. The operation technical of casting in the process has an influence on cooperation scale. After the expansion steel pulling into the sand mold, the mold can produce phase change and even has effect on casting cooperation scale.

The final cooperation state of bucket tooth is result in above factors. So the key to solve cooperation doubt is precise designing size, strict processing controlling and known about reasonable casting technology of scale.
