Apparatus for heat treatment of strand material

摘要

Apparatus for heating strand material comprises two tubular liquid containing manifolds in liquid connection with a plurality of elongate tubular strand heater members and a tubular housing which contains a liquid heating unit and a liquid circulation pump. The tubular housing is connected by its ends to the central regions of the two manifolds and each heater member is connected at each end to a manifold by a short tube. The circulation pump comprises a rotary axial flow vaned impeller and an expansion tank is mounted above the tubular housing.
