Vertical Atmosphere Furnaces series VAF and PAF

Pit-type atmosphere furnace (PAF)

This type is fully automated with sliding safely opening door. Vertical type batch loading/unloading carries on by transporter crane. The furnace housing is composed of carbon steel. The internal wall is lined with fibre insulation. There is a inlet/outlet of cooling gasses on the furnace bottom. All heat treatment processes are controlled by a logic controller according to programmed data. The control system contains a register with written down function and auto data save on a hard disc. The ceramic fiber insulation lines internal furnace wall. This insulation type shortens warming-up time, saves user´s money and natural environment. The furnace heating system is installed around the batch (360°) directly on internal chamber wall. It ensures best usable values such as the temperature uniformity in whole the heat zone. The furnace consists of an external air blower which cools the heat zone down to 100°C.

Processes: tempering, annealing, hardening, normalizing.
