An apparatus useful in treating a carbon fibre precursor material under predetermined conditions of temperature and gaseous environment. The apparatus includes a housing, and a reaction chamber disposed within the housing. The reaction chamber is elongate and has an entry port at a first end and an exit port at a second end. The entry and exit ports are configured to allow passage of a carbon fibre precursor material into and out of the reaction chamber respectively. A heater or heating system is configured to heat a wall of the reaction chamber. In use, a precursor material is passed through the reaction chamber and is thereby heated.

A dross processing assembly includes a stirring station at which dross in a first dross recovery vessel is stirred and a pressing station at which previously stirred dross in a second dross recovery vessel is pressed simultaneously with the stirring of the dross in the first dross recovery vessel. The stirring station and the pressing station may be commonly housed in an enclosure. A conveyor system may advance dross recovery vessels through the dross processing assembly for continuous dross processing.

The present invention relates to a furnace device for heating a plate, in particular a metal plate, by convection. The furnace device has a housing, in which a temperature control region for temperature-controlling a component part and an adjustment region are formed, wherein the adjustment region has a temperature control device for adjusting a temperature of a temperature control fluid. Further, the furnace device has a positioning device for positioning the plate in the temperature control region in a predetermined orientation, and a ventilator, which is arranged in the housing and which is adapted to circulate the temperature control fluid in the housing between the temperature control region and the adjustment region such that the temperature control fluid is flowable in a flow direction along a surface of the plate.
