Utilization of waste Annealing Furnace Gas for Core Drying Process in Ductile Iron Pipe Plant

0 0 /5
For drying the sand core which is utilized during Ductile Iron Pipe casting, we were using Thinner based paint and putting fire for drying it was not only unsafe but also incurring cost of thinner based paint, it was a concern for the management and it put forward the challenge to find any alternative for this, this eventually resulted in finding the alternate solution for this by using Waste heat flue gas of Annealing furnace(200 deg. C) for core drying in place of thinner based paint.
