Howto
- Sand blast
- Base bath - 10 minutes min
- Base bath - 7 minutes min
- Flux - ammonium
- Actual dip - 3.5 minutes (until base metal reaches melt temp of 835F)
- Water - trapped water explodes, and is dangerous, so first dip is dangerous and venting must be assured.
- Zinc - 2400 lb blocks are the feedstock for hot dip baths. This is only 0.1 cubic meter - or 4 cubic feet.
