Abstract

This paper introduces the status quo of current heat treatment procedure of aluminum alloy castings,Heat treatment furnace burner uses cold air as a fuel and the resulting emissions are directly discharged to the atmosphere instead of being recovered, so a great number of residual heat resources are wasted. Therefore, the basic principle - waste gas heat utilization is proposed, but equipment operation synchronous rate, utilization of system equipment and one-time full recovery shall be considered, finally, "heat supply of aging oven" is selected according to actual situation of this project. The cut-and-try heat balance method is applied to calculate the consumption of natural gas in each furnace per hour and energy economic ratio after waste heat recovery, produces the obvious energy saving effect and high investment value and guides and demonstrates the energy saving transformation of heat treatment procedure of aluminum alloy castings.
