The segment discusses the ongoing renovation of the blast furnace, expected to be reignited in a few days.

• A new hot air nozzle is being installed to stoke the embers as part of the renovation.
• The production engineer Rain Clock is overseeing the €200 million sanitation project.
• The renovations take place in areas not normally accessed during operation to perform the necessary repairs.

The segment provides details about the blast furnace's dimensions, capacity, and the work of the engineers.

• The furnace has been functioning for 20 years and requires improvements.
• Only Rain Clock and a colleague can access the last open ventilation gallery, and they film with a mini camera for safety reasons.
• The furnace is the largest in Europe, with a volume of 5500 cubic meters and a diameter of nearly 15 meters.

This segment outlines the blast furnace's production capacity and the meticulous work required to maintain it.

• The furnace can produce up to 12000 tonnes of pig iron daily.
• Maintenance procedures like taping need to be done by hand to ensure precision and proper sealing.
• The heat must be confined to prevent it from leaking to the furnace's outer shell.

The segment describes the working conditions and the continuous production process of the blast furnace.

• Rain Clock is accustomed to the foggy conditions when it rains around the 100-meter tall furnace.
• Thyssenkrupp has four such furnaces in the Ruhr region, producing pig iron for steelmaking.
• As a production engineer, Rain Clock ensures that at least three furnaces remain operational.

This segment provides insight into the continuous operation and quality control measures in place at the facility.

• The production process involves continuously filling a torpedo depending on the speed, lasting between 30 minutes to an hour.
• After quality control checks, Rain Clock orders the furnace to continue running.
• With 12000 employees, the factory is the largest in Europe, boasting enormous dimensions and efficiency.

The segment covers the routine and the personal connection of the workers with the production process.

• Rain Clock finds the daily production routine exciting, with each day bringing different challenges.
• The pouring of molten iron is particularly fascinating, a process he admired since childhood, following in his grandfather's footsteps.

The segment highlights the control station operations and the materials used in the blast furnace.

• Rain Clock comes from a family of metalworkers and studied metallurgy, which is common among his colleagues.
• The control station is modern and electronic, ensuring constant communication with outside employees to quickly address problems.
• The furnaces are filled with two types of materials: iron ore (red) which melts into pig iron, and coke (black) which is part of the charge mixture.

The segment describes the final renovation steps of the blast furnace and the urgency to resume operations.

• At the end of the day, Rain Clock meets with construction workers at a 40-meter height to review the completion of cold water connections.
• The team works day and night to ensure that the blast furnace will be operational again in just a few days.
