Maximizing Safety and Improving Efficiency with Sow Furnace Technology

Casthouses in North America are increasing safety and operational efficiency through Pyrotek sow preheater furnace technology.


"We want our customers to have the safest process possible," says Steve Sames, Sales Engineer for Pyrotek and a former Casthouse Manager. "Using the sow preheater removes the possibility of a cold/wet sow going into your furnace." 

Along with a safer operation, casthouse managers are seeing increases in productivity and efficiency. One casthouse manger Pyrotek works with in New York state, USA, saw the most improvement during alloy changes. In a charge of 40,000 pounds (18,000 kilograms) of prime aluminium T-bar or ingot/sow, he saw a reduction of melt times from 7 hours to 4 hours. He also saw an increase in production of 35,000-70,000 pounds (16,000-32,000 kilograms) in the first month of use.

"If I were still a casthouse manager and didn't have a sow preheater, I would get one," says Sames. "It's the piece of mind that your employees are safe that's the most valuable."
