Control the temperature up to 1000°C of a 3-zones tubular furnace

How can I control the temperature and power supply a tube/tubular furnace with a Arduino? This furnace have 3 independent heating zones and I need apply heating in ramp of different velocity and then maintain the temperature stable.

You will need appropriate temperature sensors and a suitable furnace power supply controller. Given those, it should not be difficult to have an Arduino control the temperature.
