Description

A kind of copper and copper alloy tube bar heating furnace

Technical field

The utility model relates to heating furnace field more particularly to a kind of copper and copper alloy tube bar heating furnace.

Background technique

Seam resistance furnace is one of the main heat-processing equipment of domestic and international metal material and its alloy material tube rod, with For 130 type seam resistance furnace of ZL94-, there are it is various objectively due to, equipment fault is high, causes work efficiency It is low, and seriously affect the direct motion of production, become the technology " bottleneck " of enterprise's production, seam resistance furnace is primarily present following several ask greatly Topic:

1. output power design is insufficient.Output power is relatively low, only 30KW, when heating big tube rod due to adopting power mode, Speed is slow, the temperature not reached requirement, it is difficult to meet the needs of quickly making first-born production, cause production efficiency low, product yield It is relatively low；And if raising temperature, resistance wire are easily blown；

2. unreasonable structural design.(1) heating element arrangement is unreasonable.Heating element is 4 millimeters of OCr25Al5 high of diameter Electric resistance alloy silk is placed in wall and furnace bottom behind two side of burner hearth and puts on brick after being concatenated, intermediate link is more, resistance wire fault point is more, It is easy to damage, furnace, baker need to be built again, extremely inconvenient, labor intensity of workers is big, not only delayed work but also mistook；(2) furnace cavity is set It counts small.Heating element after of short duration use, Yi Fasheng crackle, kinking, abjection put brick, it is even short-circuit phenomena such as so that heating unit Part maintenance and replacement are more frequent, affect the direct motion of production；(3) furnace lining is easy to damage.1. collapsing.Furnace lining in use, Vulnerable to shock, cause to collapse damage；2. inconvenient.It need to often remove furnace internal oxidition metal fillings, furnace lining easy to damage, also very not Just；3. refractory material cracks.In use, it can cause refractory material that cracking occurs and damages furnace lining due to being brought rapidly up；

3. production cost is too high.Since heating element service life is short, frequently, maintenance cost increases, in addition for maintenance replacement It delays work, cost of mistaking, has seriously affected economic benefit；

4. there are security risks.Operative employee's usually insulation meeting due to improper use, between phase and phase, eduction rod and furnace shell Cause short circuit, seriously affects the person and equipment safety.

5. metal pipe bar heating temperature is uneven.When especially heating to big tube rod, fire box temperature is uneven, influences gold Belong to tube rod phase transformation, and then influences the progress of the quality and subsequent handling of tube rod.
