Continuously Casting of Micro Section Babbitt Alloy Flat rods Through Dynamic Molds to Prepare Near-Final-Size Wire
Babbitt alloy is usually used as wear reducing layer,but there are the low bonding strength,low material utilization,and segregation.Overlay welding is gradually replacing casting for preparing the wear reducing layer.Using Babbitt alloy wire for overlay welding instead of Babbitt alloy ingots is a development trend in the field.The poor plasticity of Babbitt alloy makes it difficult to prepare thin wire diameter using conventional processes such as extrusion and drawing.On the other hand,the extrusion defects such as"core wrapping"in the extruded rods are harmful for the quality of overlay welded layer.Given this,a dynamic mold continuous casting micro-section Babbitt alloy flat billet device was designed.Tthe device can continuously cast flat rods with a cross-sectional area of 24.6mm2.Through rolling,slitting,deburring and roll drawing processes,wire with the diameter less than 2.00mm was acquired,free from impurities,bubbles,core wrapping,and oil residue,good economic efficiency.
