The Cast Iron Rivet Welding Plates is mainlyuse for rivet and welding techniques. The holes and T-slots on the workingsurface can clear the iron cake and welding castoff during the riveting andwelding processing. The T-slots are using for fixing the weld assembly. The raw material of cast iron rivet welding plates is the high-strength cast iron GG20-GG30 (HT200-HT300). After twotimes annealing treatment, the cast iron rivet welding plates have the featuresof steady precision and abrasion resistance. The size range is from 100mm 100mm to3000mm 8000mm. Larger one can be made according to thedrawing.
