Abstract
The utility model relates to a water cooling protective sleeve for a submerged arc furnace. In the water cooling protective sleeve for the submerged arc furnace, a large quantity of welded seams exist, so that the possibility of leak points is increased, and the manufacturing cost of the water cooling protective sleeve is increased greatly. The water cooling protective sleeve comprises an inner arc-shaped plate and an outer arc-shaped plate, wherein the inner arc-shaped plate and the outer arc-shaped plate are connected with each other through a plurality of uniformly-arranged pivots; the left and right sides and tops of the inner arc-shaped plate and the outer arc-shaped plate are provided with water stop sheets respectively; the bottoms of the inner arc-shaped plate and the outer arc-shaped plate are provided with steel pipes, so that a box is formed; the top of the box is provided with a water outlet and a water inlet; the water inlet is communicated with the steel pipe arranged at the bottoms; the other end of each steel pipe is provided with a water port communicated with an inner cavity; and each steel pipe is provided with a plurality of water holes. Due to the adoption of the water cooling protective sleeve, resistance loss of circulating cooling water in the box of the protective sleeve is reduced, the length of each welded seam is reduced greatly, and deformation of the water cooling protection sleeve, caused by overlarge internal welding stress, is reduced simultaneously.
Description
Technical field
The utility model belongs to the ore-smelting electric furnace field, is specifically related to the hot stove water-cooling protective sleeve in a kind of ore deposit.
Background technology
There is a large amount of weld seams in hot stove water-cooling protective sleeve in the ore deposit of usefulness at present; The residual stress that too much weld seam has increased interior welds can make the water-cooling protective sleeve profile change; Thereby in the process that electrode moves up and down with low hood on sealing device mutual friction and damaging mutually; Because position while welding is more, exists the possibility of leak source also can increase, too much weld seam has also increased the manufacturing cost of water-cooling protective sleeve greatly.In addition, it is not fine that the water-stop sheet Welding Structure causes the recirculated cooling water circulation in the water-stop sheet end regions, forms the dead band easily; The dead band local temperature is raise, will produce gas, press in local generation is higher when temperature is elevated to a certain degree; Press in this height not only water-cooling protective sleeve to be had a negative impact, these gases form " vapour locking " and then form " steam hammer " in the effusion process simultaneously, cause the rubber water pipe to come off; Compelled blowing out is handled, and influences ordinary production.
The utility model content
The technical problem that the utility model solved provides a kind of resistance damage of recirculated cooling water in protective sleeve that reduce, and has reduced the hot stove water-cooling protective sleeve in ore deposit because of the water-cooling protective sleeve distortion of the excessive generation of welding interior stress.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
The cold protective sleeve of a kind of ore deposit hot water; Its special character is: comprise arc inner panel, arc outside plate; The arc inner panel is connected through the rivet that several evenly are provided with the arc outside plate; The left and right sides and the top of arc inner panel and arc outside plate are respectively arranged with water-stop sheet, and the bottom of arc inner panel and arc outside plate is provided with steel pipe, constitute casing; The top of described arc inner panel and arc outside plate is provided with delivery port and water inlet; Water inlet is communicated with the steel pipe that the bottom is provided with through pipeline; The other end of steel pipe is provided with the mouth of a river and is communicated with the inner chamber of arc inner panel and arc outside plate, and steel pipe is provided with several water holes.
Several water holes that are provided with on the above-mentioned steel pipe are according to the from left to right ascending successively setting of diameter.
Compared with prior art, the beneficial effect of the utility model:
1, not only reduced the resistance of recirculated cooling water in the protective sleeve casing and decreased, and significantly reduced fusion length, also reduced water-cooling protective sleeve distortion simultaneously because of the excessive generation of welding interior stress in this.
2, the aperture of the inboard different-diameter that distributes of bottom thick walled steel tube makes cooling water flowing in water-cooling protective sleeve more reasonable.
3, adopt thick walled steel tube to replace traditional individual layer steel plate shutoff bottom half inner and outer plates, because the water-cooling protective sleeve bottom is in the high-temperature region, the thick walled steel tube of water flowing cooling is all having better effect aspect mechanical performance and the thermal stress resistance destruction.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 looks part sectioned view for the right side of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
Referring to Fig. 1,2; The utility model comprises arc inner panel 4, arc outside plate 2; Arc inner panel 4 is connected through the rivet that several evenly are provided with arc outside plate 2; The left and right sides and the top of arc inner panel 4 and arc outside plate 2 are respectively arranged with water-stop sheet, and the bottom of arc inner panel 4 and arc outside plate 2 is provided with steel pipe 1, constitutes casing 5; The top of arc inner panel 4 and arc outside plate 2 is provided with delivery port and water inlet; Water inlet is communicated with the steel pipe 1 that the bottom is provided with through pipeline; The other end of steel pipe 1 is provided with the mouth of a river and is communicated with the inner chamber of arc inner panel 4 and arc outside plate 2, and steel pipe 1 is provided with several water holes.
Several water holes that are provided with on the above-mentioned steel pipe 1 make water reasonably be full of whole water jacket cavity according to the from left to right ascending successively setting of diameter.
Through water-stop sheet recirculated cooling water at first is transferred to bottom thick walled steel tube 1; Cooling water is through bottom thick walled steel tube 1; Discharge from effluent pipe mouth after being full of in the water-cooling protective sleeve casing from the bottom to top, its thin portion structure such as Fig. 2 reinforce through rivet 3 between water-cooling protective sleeve outside plate 2 and the inner panel 4; Adopt the solder joint form between rivet 3 and the inner and outer plates; Adopt this scheme not only to reduce the resistance of recirculated cooling water in the protective sleeve casing and decrease, and significantly reduced fusion length, also reduced water-cooling protective sleeve distortion simultaneously because of the excessive generation of welding interior stress in this.The bottom of water-cooling protective sleeve is to adopt thick walled steel tube 1 as the welding end socket; Water-cooling protective sleeve bottom thick walled steel tube is provided with A, two mouths of a river of B; Cooling water directly leads to the A mouth of water jacket bottom thick walled steel tube through water inlet pipe, discharges inboard the distribution directly through ascending little water hole between A mouth and the B mouth behind the thick walled steel tube of flowing through from the B mouth; Make water reasonably be full of whole cavity; Because the water-cooling protective sleeve bottom is in the high-temperature region, compares with traditional unichassis, adopt the thick walled steel tube of water flowing cooling aspect mechanical performance and the thermal stress resistance destruction better effect being arranged all.At first recirculated cooling water directly imports the protective sleeve bottom, promotes the water-cooled wall thickness to the high-temperature region; Next reduces the magnetic loss that big current field causes the protective sleeve bottom, prolongs the service life of protective sleeve greatly.
