Abstract
The utility model relates to a novel electric arc furnace water-cooling furnace cover which comprises a bottom plate. The bottom plate is sequentially provided with multiple round partitions from outside to inside. A circulating waterway is formed between every two adjacent round partitions, the top of each circulating waterway is sealed through a ring with the same width as the corresponding circulating waterway, each circulating waterway is provided with a water inlet, a water outlet and a partition board, each water inlet and the corresponding water outlet are formed in the two sides of the corresponding partition board, and each water outlet is provided with a flange; the top of the innermost round partition is provided with a small center furnace cover body, feeding holes are formed in corresponding positions of the small center furnace cover body and the bottom plate respectively, and electrode holes are evenly formed around the feeding holes. The novel electric arc furnace water-cooling furnace cover has the advantages that the tops of the circulating waterways are sealed, water channeling is prevented, flow of water is accelerated, and heat loss is little; each water outlet is provided with one flange, so that descaling can be directly carried out by opening the flanges when descaling is needed, time is saved, energy is saved, consumption is reduced, and repairing and waste utilization are achieved.
Description
Technical field
The utility model relates to a kind of New Arc stove water cooled cover.
Background technology
Electric arc furnaces mainly divides upper, middle and lower trisome.Especially the bell on top, because environment temperature is high, meets the control of demineralized water index not in place, and inside is easy to fouling.Electric arc furnace water cooled bell (with reference to figure 1 and Fig. 2) originally comprises base plate 1, the outward flange of base plate 1 is provided with a circular partition 2, upper strata adopts monoblock steel plate 12 to do spot welding, in real work, run into following problem: when (1) scale removal, upper strata monoblock steel plate 12 must be cut open and can operate, waste time and energy like this, efficiency is extremely low, increase cost; (2) 4 road circulation waterways 3 channeling water back and forth, causes under high temperature water outlet interrupted, has reduced service life.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, and a kind of New Arc stove water cooled cover is provided.
Based on above-mentioned purpose, the utility model adopts following technical scheme:
New Arc stove water-cooled center bell comprises base plate, it is characterized in that: progressively from outside to inside on base plate be provided with some circular partitions, every two adjacent circular form circulation waterway between cutting off, the top quilt annulus equal with circulation waterway width of each circulation waterway seals, on every circulation waterway, be equipped with water inlet, delivery port and dividing plate, water inlet and delivery port are distributed in the both sides of dividing plate, and delivery port is provided with flange; The circular top cutting off of innermost layer is provided with small center furnace cover, and the opposite position of small center furnace cover and base plate is equipped with charging aperture, is equipped with electrode hole around charging aperture.
The utility model water cooled cover has done following improvement: 1) top of circulation waterway is sealed, prevent channeling water back and forth, accelerated flowing of water, thermal loss is little; 2) per pass delivery port is provided with flange, when scale removal, as long as open directly scale removal of flange, not only can reduce the time like this, and energy-saving and cost-reducing and repair the old and utilize scraps.
