rp electrode graphite

Solution to rp electrode graphite breaking

The damage of rp electrode graphite is partly due to its operation and control, but the quality of rp electrode graphite itself is also a decisive factor in the damage.

(1) The reason for the fracture of the rp electrode graphite joint is that the joint plays a key role in the connection of the rp electrode graphite during the steelmaking process. The quality of welded joints is directly related to the use of rp electrode graphite in steelmaking. The connection area formed by the rp electrode graphite and the joint is a complex part with large electrical, thermal, and mechanical loads, and it is also a common part of fracture. According to relevant data, more than 80% of rp electrode graphite accidents in electric furnace steelmaking are caused by joint fracture or loosening. As far as the quality of the joint itself is concerned, the main reasons for the joint fracture are: small volume density, low strength, easy to break during use; high electrical resistivity, and the temperature of the joint rises quickly when energized, which will cause greater heat generation at the rp electrode graphite joint stress. Increase the possibility of joint fracture; insufficient fracture strength; internal cracked joints mixed with finished joints, forming major hidden dangers; joints and rp electrode graphite processing accuracy indicators are unreasonably matched and easy to break.

(2) The reason for the fracture of rp electrode graphite is usually that the probability of rp electrode graphite fracture is low. The main reasons for the fracture of rp electrode graphite are: quality defects of screw holes; insufficient bulk density and strength of rp electrode graphite; mismatch between rp electrode graphite and joint index, and processing accuracy is not high; deep cracks at the end of rp electrode graphite are due to threaded holes Caused by substandard quality. Thermal shock resistance of rp electrode graphite. In addition, there is a great risk of damage to the rp electrode graphite with no internal transverse cracks detected in the finished product.
