It is really huge wattage, which probably requires 3 phase current. It is good to know that Lindberg protects the life of the heating elements by slowing down the heat-up rate. I will try to follow this approach.
Based on my considerations the full wattage would bring your furnace to 800 C within 10 minutes but at the cost of thermal shocks.
Modern high temp furnaces use molybdenum disilicide elements.
Buying Kanthal A1 wire, you are sure it is from Sandvik in Sweden. Winding the coils using the lathe is not very difficult.
