The structure of this article details the elements of design, execution and operation of a heat treatment furnace (TT). It features a gas-based cylinder heat source supercharged by a blower that brings extra air to the centrally arranged burner area in the upper furnace panel. The walls of the furnace enclosure are lined with refractory brick, the housing consists of steel sheet S235JR and is placed on 4 feet that allow to adjust the vertical position of the furnace by means of screw assemblies. The oven temperature is adjusted by means of onehour taps that offer the possibility of varying the flow rate of the fuel mixture and the additional air flow brought by the blower. The indoor temperature is monitored using a thermocouple. The furnace also features a metal door lined refractory. The performance of the furnace in operation can be assessed based on the temperature reached, the heating speed, the controlled cooling speed (in air flow, possibly), based on the types of TT that can be achieved on this furnace.
