4.product analysis
Unreasonable classification of slag discharge results in difficulty in slag discharge and exhaust.
5.Improvement measures
The following is for reference:
1. In the original plan, the input materials are all OK, and the slag discharge is a major flaw, so it is normal for the slag discharge to have holes and defects.
2. Adjustments to the original plan:
Do not seal off the original slag discharge, increase or increase the slag discharge of the sliders on both sides
At present, the parting of the mold structure cannot be moved to the movable mold, and the parting of the mold reopening must be staggered with the feed.
6.tips
About slagging:
