Hi everyone.
Currently In a large steel manufacturing company they use customized welded HSS cutting tool for machining roll mills for manufacturing wide flange beam hot rolling roller.
They use 1.3355 (S200) steel sheet that is welded to steel body and cut using wire cut machine to desired form for finish machining the form. the profile of the cutter sometimes is so large about 200*200mm and the thickness of HSS they use is 15mm.(the diameter of roller is 2meter and the cutting speed is about 7-10m/min)
now they asked me about replacing the cutting tool material . i suggested them replacing HSS with carbide plate that can be brazed and cut with wirecut but they told carbide has not the desired toughness and will chip at edges easily .
now I'm thinking of hardfacing the tool edge (complete profile shape) with hardfacing materials like stellite family , deloro family or even abrasion resistance electrode( like E10-UM-65-GZ , etc. )then grind the face and wire cut to the shape . ( the depth of the weldment would be 2-3mm)
do you think it would be an optimal method for making cutting tool . if so what material you suggest for harfacing alloy .
Any help would be really appreciated .
