Advanced Design for Hot Forming and Press Hardening

This paper presents an advanced innovative design of a continuous roller furnace. These types of furnaces are generally used in hot stamping / press hardening lines. Design is focused on optimal heating layout, modern drives of rollers, new design of furnace's input and output without movable parts and other items respecting the optimal technological and technical aspects. The cycle time of the hot forming process is a function of several technical parameters. Also the technological functions like the dew point temperature regulation, oxygen rate regulation with permanent monitoring function are described. All results are based on the theoretical background of heat and mass transfer, confirmed by numerical FEM (Finite element method) analysis.
