Mechanical test furnace - 1 100 °C
The apparatus that performs the reduction test through electric heating under load serves as static iron ore determination device according to ISO 7992 and ISO 11256 and without pressure can be used for other ISO tests like ISO 11258, ISO 4695, etc.Abiding by the ISO standards, the reduction test apparatus comprises of the pit furnace, the retort, the measuring and control station, the process gas control and the weighing equipment. The reduction furnace is made like a vertical tube furnace. The retort and the pressure device hangs freely swinging within the furnace below the balance. The furnace, the balance along with the retort are built inside a shock-resistant frame mount. The regulation of the temperature is done by SIEMENS S7-PLC control system. Only the over temperature circuits are designed according to the laid down regulations for hardware controllers. The gas regulation per gas circuit is with
