Box Type Resistance Furnace
Temperature range is where the big differences show up. We make models for 1200°C, 1400°C, 1600°C, 1700°C, and 1800°C. The heating element changes with the temp. Resistance wire for the lower ranges, silicon carbide rods for the middle, and molybdenum disilicide (MoSi₂) for the really hot stuff.

Product Definition
Box-type resistance furnace is the workhorse electric furnace you see in a lot of shops. Comes in vertical, horizontal, split, or integrated – whatever fits your space.
Temperature range is where the big differences show up. We make models for 1200°C, 1400°C, 1600°C, 1700°C, and 1800°C. The heating element changes with the temp. Resistance wire for the lower ranges, silicon carbide rods for the middle, and molybdenum disilicide (MoSi₂) for the really hot stuff.
Working Principle
The chamber has electric heating elements inside – resistance wires mostly. Turn on the power, current flows, the elements get hot. Electrical energy turns into heat.
The design of the chamber gives you good heat transfer. The heat spreads through the whole space. You hit your target temperature and hold it there accurately.
Features
- Flexible. Open chamber, movable trolley on some models. You can load odd sizes and heavy weights. Much easier than trying to cram everything into a pit or bell furnace.
- Handles heavy loads. Big castings, large forgings – stuff that won't fit anywhere else goes into a box furnace.
- Good temperature control. Multi-zone heating plus PID controller. We hold within plus or minus 5°C.
- Sturdy. Heavy steel frame, thick refractory lining. Takes the heat and keeps coming back for more.
- Easy to maintain. Simple structure. When something breaks, you can get to it. Part replacement is straightforward.
- Safe. Tight door sealing, safety interlocks, overheat protection. Standard stuff but we don't cut corners.
- Saves energy. Ceramic fiber lining cuts heat loss. Heats up faster, cools down faster, uses less power.
Applications
The box-type resistance furnace is widely used in many fields,including:
Heavy machinery and forging
Annealing, normalizing, stress relieving for large castings, forgings, structural steel components.
Automotive manufacturing
Big parts – engine blocks, crankshafts, heavy duty gears.
Steel and metal processing
Tempering and annealing thick steel plates, large pipes, heavy metal coils.
Aerospace
Large aircraft structural components and landing gear parts.
General foundries
Batch heat treatment of iron and steel castings.
Research and labs
Material testing and small batch experimental work.
