Wholesale High Quality Small Box Type Tempering Furnace Manufacturer in China

China  Factory wholesale Price Small electric heat treat box type tempering furnace for sale - Rexin industrial furnaces manufacturer supplier

The box-type tempering furnace is a national standard type of periodic operation box-type furnace. It is equipped with a hot air internal circulation fan on the furnace top and is mainly used for tempering heat treatment of alloy steel products and various metal parts, as well as heat treatment of light alloys such as aluminum alloys and copper materials, including solution treatment, annealing, and aging.

Design Advantages:

1.Improved temperature uniformity ≤±5℃ throughout the working zone

2.Enhanced heat circulation for consistent tempering results

3.Rear-mounted fan saves front space and simplifies operation

4.Suitable for batch processing of metal parts requiring precise temperature control

1. The outer shell of the box-type tempering furnace is made of Q235 steel plate, and the inner lining is made of 3mm perforated stainless steel sheet. The furnace chamber is movable for easy maintenance and removal as a whole.

2. The temperature control system uses a power controller, with other components from Chint or Schneider Electric. It includes functions such as heat preservation timer and over-temperature alarm. The temperature control system uses a touch screen to effectively prevent over-temperature and temperature differences, ensuring more uniform temperature throughout the furnace chamber. It features 6-point temperature sensing control. The ammeter is digitally displayed for easy and clear reading.

3. The furnace door is a rocker-arm type, opening to one side. The door fits tightly against the furnace body surface to ensure uniform air circulation within the chamber. The furnace bottom is designed with guide angle irons for positioning forklifts. 4. A powerful, air-cooled centrifugal fan is installed to ensure more uniform temperature within the chamber. The fan has an extended shaft, and the blades and shaft are made of 304S stainless steel. The blade diameter is 400mm.

5. The heating element device uses spiral heating wires arranged in layers for easy disassembly and maintenance. The heating wires are positioned at the top, bottom, left, right, and near the furnace door to ensure uniform temperature within the furnace.
