Features of resistance alloy wire :
Our furnace resistance alloy heating ribbon is of high quality with following features:
1. A quite reasonable price
2. Stable performance resistance alloy wire : high working temperature(The highest temperature can be 1400), high strength under temperature, corrosion resistance, long life-span, allowable high surface load, small specific gravity, good formability and weldability.
Delivery status and supply state of furnace resistance alloy wire :
Wire and plate with the looseness or oxidation colour soft modal supply.
Strip except special requirements outside, general with after annealing oxidation colour supply.
The flat silk thread and protecting gas to light after annealing soft modal supply.
2, product packaging of furnace resistance alloy heating ribbon
Wire or strips to pack cloth bandaged volumes supply.
Thread and flat silk, axis encapsulate supply.
3, export products and users have special requirement, negotiation.
note
1, when the design should be based on the power wiring method, reasonable surface load, the correct choice of silk diameter,
2, before installation coping furnace thorough examination, cleared ferritic, "carbon, and the electric stove contact risks to avoid short circuit, in case caused furnace silk breakdown,
3,when installation should press design wiring method properly connected;
4, in use before should check the sensitivity of the temperature control system, in case of failure, cause temperature burnt
