Non-standard Heating System of Chamber Heat-treatment Furnace with Fixed Hearth

Abstract

This article describes specific features of thermal operation and design of new heattreatment furnaces constructed and operated in conditions of production restrictions. The requirements for high-quality and energy-efficient production of finished metal products are especially manifested during final heat treatment aimed at receiving the specified physical and mechanical properties of the products.



Keywords: heat-treatment furnace, heating for hardening, steel sheet, heating system, high-speed recuperative burner
