    Annual production of 60,000 tonnes of liquid iron

    The maximum production capacity of the current HIsarna pilot plant: 60,000 tonnes of liquid iron a year. As a comparison: Blast Furnace 7 in IJmuiden produces 10,000 tonnes of liquid iron a day.

    Preheating oven to 1,200 degrees Celsius

    Before the start of each testing campaign burners preheat the reactor of the HIsarna plant to a temperature of about 1,200 degrees Celsius. Next, a layer of liquid iron is poured into the bottom of the melting vessel, to facilitate the start-up of the process.
