Tulaga Faʻatino
1. The furnace is horizontal, single chamber, horizontally loading structure. The way of opening door is optional according to customer's requirement.
2. The hearth consists of wide nickel-chromium heating zone and multi-layer stainless steel heat insulation with good temperature uniformity performance.
3. Tempering is finished under the high vacuum. The jobs after treatment are bright without any color changes.
4. O le faiga malulu vave e aofia ai i totonu exchanger vevela ma kasa cooling taamilosaga e mafai ona puipuia lelei vaega mai tempering brittleness.
5. Vacuum tempering tube furnaces have convection heating device, which can ensure the temperature uniformity at the state of low temperature.
