Hearth structure of unmuffled furnace: The whole hearth forms a circulated channel to make internal atmosphere flow circularly, guarantee atmosphere diffuse evenly, reduce carbon deposition , prolong radiative pipe's life and make quality stable.
Bottom of hearth adopts anit-cementite “08”brick , “06” temperature-preservation brick and alumina silicate fibre; and the roof adopts carborundum cover, imported cerablanket and alumina silicate fiber; so the whole hearth has remarkable properties of temperature preservation and energy saving.
New type Sweden transmission mechanism: Transfer mesh belt stably with no deflection and low noise; adopt variable frequency speed regulation to control; display time for quenching and heating; operate intelligently and easily.
The first-developed sealing device: Save about 65% atmosphere; layer of cementite is much deep when it is not less than 10~100pa and the surface is much smooth. This device is developed and tested by our company.
Cementite control is composed by oxygen probe, carbon control instrument and valve with high control precision and good effect of cementite. While temperature and carbon potential is recorded with paperless recorder.
Perfect automatic control system is safe and convenient; as well as may be equipped with feeding machine, cleaning machine and annealing furnace to form automatic production line.
Working temperature: 950℃ below;
