There is provided an electrolytic tank assembly facilitating alignment and levelling of an electrolytic tank with respect to adjacent electrolytic tank. A levelling assembly can include a plurality of adjustable levelling mechanisms being independently actuable to cause upward or downward movement of the electrolytic tank. A sole assembly can include friction and sliding soles for controlling transversal movement of an electrolytic tank with respect to support beams onto which the tank is supported. A strap assembly comprising a vertically extending strap and a connector provided at an end of the vertically extending strap can be connected to each adjustable levelling mechanism of the levelling assembly. Various type of connectors can be provided at the other end of the strap to provide anchorage to accessory for operation, lifting, maintenance, etc.

The system includes a raw material predrying kiln, a preheating kiln, a reduction rotary kiln, a cooling rotary kiln, a ball mill, a magnetic separator, a reduced iron powder drying kiln, a blank prefabricator, a blank drying kiln, a sintering furnace, a fused salt electrolysis tank, a titanium cleaning device, a filtering device, a vacuum dryer, a waste heat boiler, and a steam turbine generator. In the present disclosure, a high-temperature flue gas produced by the reduction rotary kiln is directly used to preheat a raw material. The CO-containing high-temperature flue gas discharged by the reduction rotary kiln and the CO discharged at the fused salt electrolysis stage are recovered and used for power generation and steam production of the waste heat boiler. Due to a low moisture content of the flue gas, a low-temperature flue gas obtained after the waste heat recovery is used for drying.
