Chamber Furnaces with Radiation Heating N 7/H - N 1491 —N 7/H These universal chamber furnaces with radiation heating are designed for highly adverse conditions during heat treatment. They are ideally suited for tooling construction processes and in the hardening shop, such as annealing, hardening or preheating for forging. The use of various accessories allow these furnaces to be modified for your application. Standard Features, Table-Top Models N 7/H - N 17/HR ■ Compact, low-cost construction ■ Heating from floor and both side walls ■ Heating elements on support tubes ensure free heat...

We recommend this useful accessory equipment for applications up to 1100 °C to protect the furnace floor. Tmax 1100 °C Three raised edges Hole for draw hook (see page 22 for draw hook) Made of heat-resistant alloy 314 (AISI)/(DIN material no. 1.4841) Material thickness 4 mm Larger plates and custom dimensions available upon request Article no. 601603960, 1 set of fiber insulation cord, 5 strips of 610 mm each

Neutral Annealing Coal ■ For protection of tool steel against oxidation and decarburizing, binds oxygen at all process temperatures ■ Workpieces are placed in a hardening box with annealing coal ■ Reusable multiple times with addition of approx. 20 % new granulate

Single parts requiring protection against decarburizing can be wrapped in a stainless steel heat treating foil off the roll or packed in prepared envelopes or bags. The rolls are available in various lengths and widths, the envelopes and bags are supplied in various dimensions. Foil off the roll can be cut to size using gold plates scissors and the workpiece can be wrapped to requirements. See page 9 for more details about accessory supplies required, such as tongs and special gloves. The protected workpiece can now be loaded into the heated furnace. Due to the foil’s thinness, it takes on...

Annealing Envelopes Annealing envelopes useful up to Tmax 1200 °C For hardening small parts Airtight lock by means of folds of a fold lock or suitable tools (page 8) Rapid heating of the foil binds the oxygen in the annealing envelope preventing virtually all oxidation and decarburizing Rapid quenching in air, oil or water, ensuring high dimensional accuracy Workpieces are placed as tightly as possible in the annealing envelope Envelopes made of ultra-thin stainless steel heat treating foil, welded on three sides, for single use

Working with the Protective Gas Annealing Bag and Holder When workpieces made of air-hardened steel must be heat treated under protective gas and quenched, the protective gas annealing bag with holder is an optimal solution. This system consists of a holder with charge carrier and protective gas tube as well as a bag made of stainless steel heat treating foil. We would be pleased to carry out trials at our technical center. The charge is placed on the charge carrier and covered with the protective gas annealing bag. The bag is preflushd with protective gases such as argon, nitrogen or...

Protective Gas Boxes for Models N 7 - N 641 Working with Protective Gas Boxes for a Protective Gas Atmosphere The hardening boxes for heat treatment under protective gas are equipped with a protective gas intlet and outlet. A box with protective gas is advisable for larger workpieces requiring defined heat treating. We would be pleased to carry out trials at our technical center. Up to furnace model N 61/H with downward door opening the gas ductway is laid through the upper section of the door collar, for larger furnaces with upward door opening the supply line is laid through the lower...

Protective Gas Boxes with additional Vacuum Lid for Models N 7 - N 161 Working with Protective Gas Boxes with additional Vacuum Lid to ensure Protective Gas Atmosphere When heat treating bulk goods and hollow parts under defined protective gas atmosphere we recommend the usage of protective gas boxes with an additional vacuum lid. Thus the traces of oxygen in the box can be reduced by a considerable amount which improves the quality of the components accordingly. These boxes are equipped with a lid for top charging, protective gas inlet and outlet as well as a vacuum lid with rubber sealing...

Vacuum Pump Oil sealed rotary vane vacuum pump for universal use within the low vacuum range. Highly compact and low noise construction. Vacuum pressure gauge included in delivery. ■ Sliding vane rotary pump Sogevac SV 16BG with sucking capacity of max. 16 m3/h ■ 0,5 mbar absolute ■ Connection hose made of stainless steel 1000 mm ■ Connector KF16 ■ Manometer (-1/0,6 bar) *Article no. for other possible supply voltages on request Protective Gas Boxes with Hinged Lids for Bulk Goods for Models N 7 - N 81 Working with Protective Gas Boxes with Hinged Lid for Protective Gas Atmosphere When...
