The utility model has the advantages of simple structure, convenient installation, use and operation, safety, high electric straight-heated efficiency and electricity saving, and can carry out on-line bright continuous annealing for stainless steel, ordinary steel, copper strip, etc., and can shorten the length of the heating furnace.
Description
The online clean annealing device of a kind of electrically direct-heating stainless strip belongs to metal heat treatmet annealing device technical field, is mainly used in to make stainless strip continuous annealing and the maintenance light before being welded into pipe that is on the tinuous production; Also can be used for common steel band, the online bright continuous annealing of copper strips and aluminium strip continuous annealing (non-light is handled).
In the prior art, for the ease of to the stainless strip welding, generally all earlier with special annealing device band is carried out anneal before reaching the standard grade and be rolled into volume later on again, just reach the standard grade then, annealing heating simultaneously is to adopt electricradiator to generate heat band is carried out thermal radiation.So not only operation is loaded down with trivial details, wasting manpower and material resources and time, and also heating efficiency is low, the waste electric energy, and the original light of stainless strip also can be affected simultaneously.Find no through update search online stainless strip or other similar bands are carried out anneal and can make it continue to keep the annealing technology of surface-brightening.
It is a kind of simple in structure that the purpose of this utility model is to provide, install and use that operation is all convenient, safety, the big electric current of ultralow pressure directly can be led to needs heating piecemeal continuously on the online stainless strip of annealed, the heating efficiency height, power saving, the not oxidation of strip surface after the annealing can be made, the online clean annealing device of electrically direct-heating stainless strip that continues to keep its surface brightness after the strand-anneal(ing) can be made again.
According to the ultimate principle of metal anneal with to the particular requirement of strip surface afterwards of annealing, at existing questions in the prior art, basic design of the present utility model is: guide into after stainless strip is by the Abrollhaspel uncoiling on the passage of welding plant on the production line electrically direct-heating annealing furnace is set, it is depressurized to ten volts with interior ultralow pressure power supply by transformer with three-phase electricity, and this low-voltage and high-current is directly led on the one section stainless strip L that is positioned at annealing furnace by the conductive electrode of lead and special construction, make this section band L reach annealing temperature by its internal resistance RL heating, after keeping one section annealing time through thereafter soaking pit insulation soaking, cool off again and dry up; Between above-mentioned annealing furnace and transformer, be provided with again one by the ammonia bottle for ammonia, fill the ammonia destruction furnace of the well heater of catalyzer in also being equipped with in it by above-mentioned transformer-supplied, make ammonia (NH
3) resolve into H
2And N
2Gas mixture after feed in the above-mentioned annealing furnace H wherein
2Play reductive action, with the O in the stove
2Combine and generate H
2O makes the not oxidation of strip surface after the annealing, N
2Shield, make to keep light after the strand-anneal(ing).Along with band constantly advancing on production line, the whole piece band is able to progressively continuous annealing.
The online clean annealing device of electrically direct-heating stainless strip described in the utility model, it is characterized in that this clean annealing device by operation successively successively by strip uncoiler structure 1, electrically direct-heating annealing furnace 2 and be positioned at its nearby by ammonia bottle 9 for the ammonia destruction furnace 7 of ammonia and its dress heating arrangements 8 be 2 and the 8 above-mentioned transformers 3 of powering, soaking pit 4, cooling body 5 and dry body 6 constitute, be connected by lead between the heating arrangements 8 in above-mentioned transformer 3 and above-mentioned electrically direct-heating annealing furnace 2 and the ammonia destruction furnace 7, be connected by pipeline between above-mentioned ammonia destruction furnace 7 and ammonia bottle 9 and the annealing furnace 2.
Be filled with ammonia decomposition catalyzer 10 in the heating arrangements 8 in above-mentioned ammonia destruction furnace 7.
The utility model has the advantages that simple in structure, install and use that operation is all convenient, safety, can carry out bright continuous annealing to stainless strip, ordinary steel band, copper strip etc. on production line also can be to aluminum strip continuous annealing (non-light be handled), owing to be that low-voltage and high-current is directly led to heating continuously piecemeal on a bit of band, not only thermo-efficiency height, power saving, but also time saving and energy saving, again owing to add H in the annealing furnace
2And N
2Gas mixture, both can make the not oxidation of strip surface after the annealing, help welding, make annealing back band keep original light again.Compare with existing annealing technology, process furnace length can shorten 5～6 times, and economize on electricity is more than at least 50%.
Accompanying drawing is that one of the utility model most preferred embodiment one-piece construction is installed configuration schematic diagram.
Further describe constitutional features of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: stainless strip is double uncoiling mechanism 1 uncoiling of 500kg with load-bearing earlier before reaching the standard grade, and one twists in line annealing, and another volume is standby; The band of having gone up production line after the uncoiling passes through successively again: be located at before the jig on the production line, 1.2 meters of power 40kw, length, band conductive segment L=1 rice wherein, one end is established bronze medal graphite brush, the other end is established a pair of copper alloy roller, water flowing cooling in the roller, the heating top temperature can reach 1000 ℃ and its nearby be provided with by ammonia bottle 9 for ammonia, in adorn a stainless steel cylinder, adorn ammonia decomposition catalyzer 10 again in the tube, the heating arrangements 8 that imports current flow heats from the tube two ends also is connected with ammonia bottle 9 with it by flexible pipe respectively, per hour can decompose 0.5m
