Frequently Asked Questions

What temperature range does this billet heater achieve for aluminum extrusion?

Our billet heater uniformly raises aluminum billets to the optimal extrusion temperature range of 400-500°C (750-930°F), ensuring consistent material flow and quality.

How does the refractory insulation improve billet heating efficiency?

The refractory insulation materials and ceramic fiber insulation minimize heat loss, reduce energy consumption by up to 30%, and maintain precise temperature control throughout the heating chamber.

What maintenance is required for the Kanthal/NiCr heating elements?

Kanthal/NiCr alloy heating elements require minimal maintenance, typically lasting 5-7 years with proper operation. Regular inspection for oxidation and periodic calibration of temperature sensors ensures optimal performance.
