When we pour the bucket teeth, sometimes there will be sand sticking phenomenon, so how to prevent the bucket teeth from sand sticking?1. Compared with cast iron, the pouring temperature of cast steel...
Through the observation of the casting surface, the transverse crack was found not far below the cavity hole of the bucket tooth. The crack section is oxidized seriously, without metallic luster, the ...
Electric excavator is the main equipment of mining production. The assembly of bucket teeth and bucket lips in its working device is directly related to the safety and efficiency in the use process.Ac...
1. During the installation of the new electric excavator, the geometric dimensions of the assembly joint between the inner cavity of the fighting teeth and the outer part of the bucket lip shall be ac...
According to the abrasion degree of bucket teeth, we divide the abrasion of test bucket teeth into three levels: zero level abrasion, i.e. new bucket teeth without abrasion; medium level abrasion, i.e...
In the process of excavator operation, the bucket tooth is the working part with the largest load. The average service life of an excavator is 8 years, during which 4-5 buckets are consumed. Therefore...
(1) grind the surface of the base metal to 2-3mm with a grinding wheel to remove the original working hardening layer. When the base metal has cracks, V-groove shall be opened to completely remove the...
In mining, the bucket teeth of excavators are usually made of high manganese steel. However, due to the poor geographical environment in mining operations, excavators often need to excavate hard ore, ...
In general, the bucket tooth manufacturing material and ore will interact, so in the process of excavation, the edges and corners of ore will inevitably rub against each other at the tip of the bucket...
The bucket tooth is the terminal of the working device of the excavator. In the process of excavation, the bucket tooth is the working part with the largest load and belongs to the consumable part. Es...
The bucket material of excavator has good weldability. The bucket tooth material is high manganese steel. It has single phase austenite structure at high temperature. It has good toughness and high we...
Bucket teeth of excavators are important parts of excavators which are in direct contact with excavating media. There are two common structures of bucket teeth of excavators: direct and horizontal. Di...
The bucket teeth of high manganese steel can be repaired by the following surfacing process after extensive wear and tear. (1) Grinding 2-3 mm off the base metal surface with a grinding wheel to remov...
Bucket teeth are the main vulnerable parts on shovels in open pit mines. The casting weight is 130kg, the material is ZGMnl3, and the outline size is 944mm * 300mm * 150mm. This kind of castings are u...
I. Technical requirements for heat treatment of bucket and spade teeth The purpose of heat treatment of ZGMnl3 and ZGMnl3Re high manganese steels is to ensure that a single austenite structure can be ...
In the anti-wear measures of bucket teeth of large excavators, corresponding changes and breakthroughs can be made in material selection. Because excavators have to adapt to the mining needs of mines,...
