Description
Technical field
The utility model relates to the plumbous side-blown converter of a kind of refining, is specifically related to a kind of shell structure of refining outside plumbous side-blown converter cupola well.
Background technology
Side-blown converter is more and more many in the application of China's nonferrous smelting industry, for refining plumbous existing many industrial production examples.Side-blown converter refining lead is typical bath smelting, and during melting, air port wind speed is generally at 160-190 metre per second (m/s), can reach lower more than 800 millimeters of air port when air port wind speed reaches 150 metre per second (m/s) to the stirring scope of melt in stove.China is at present for refining distance at the bottom of plumbous side-blown converter air port center line to cupola well generally within 950mm, and when this means actual production, the metal liquid in cupola well is agitated.The phenomenon that side-blown converter runs not long time cupola well dilatancy at the plumbous stylish stove of refining, masonry is upwards raised happens occasionally, and reason is the plumbous molten mass in cupola well when being agitated, and obviously strengthens the penetration of cupola well refractory material masonry.And along with the raising of air port wind speed, the intensity that in cupola well, plumbous molten mass is agitated also increases, and permeability also improves thereupon thereupon.Although leave a certain amount of dilatation joint during cupola well refractory material masonry design, seem the swell increment can eliminated completely and produce when cupola well masonry is heated, actually for the faster infiltration masonry more early of plumbous molten mass provides possibility.What the cupola well housing of current side-blown converter adopted is rigidity fastening-type structural design, object is enclosed solidly in steel sheel by refractory material masonry, this and refractory material masonry super expect expand obviously contradictory, also the distortion of whole cupola well and raising of masonry is just caused, there is potential safety hazard, affect the life cycle of side-blown converter.
Utility model content
The object of utility model is to provide a kind of inflatable shell structure that can improve the plumbous side-blown converter cupola well safety in utilization of refining and life cycle.
The utility model discloses a kind of housing refined outside plumbous side-blown converter cupola well masonry, comprise base plate, end plate and side plate, two end plates and biside plate surround that box frame is mobilizable to be placed on base plate, for slidably to connect between adjacent side plate and end plate.
The outside of described end plate is furnished with some gussets in the horizontal direction, and the length of this gusset is greater than the length of end plate, and its two ends symmetry offers slotted hole along its length; Each gusset place outside described side plate on corresponding end plate is furnished with horizontal gusset, and the length of this gusset is less than or equal to the length of side plate, and its two ends symmetry offers circular hole.
Connect by connecting attachment strap between horizontal gusset corresponding on each gusset and side plate on described end plate, connect that the link of boards end of attachment strap has slotted hole along its length, horizontal gusset link has circular hole, two pieces connect the link that attachment strap clamps two gussets and are bolted.
Described adjacent end plate and side plate overlap joint interior angle place are fitted with angle steel along short transverse, and the length of angle steel is consistent with the length of end plate and side plate, angle steel with end plate or plate-side plate welding, another side and corresponding end plate and side plate are freely fitted.
The lower end of described end plate and side plate is connected by angle ring with between base plate, and the laminating base plate welding of angle ring, another side freely fits on end plate and side plate.
Operation principle of the present utility model is as follows: make end plate and side plate surround box frame by connecting attachment strap between the gusset outside end plate and side plate, the inner connecting attachment strap is connected by the bolt through circular hole with between side plate, on the slotted hole of its outer end and gusset respective end slotted hole between be bolted, and the direction of two slotted holes is vertical, make end plate and side plate all can along corresponding slotted hole Slideslip outward like this; The angle steel in box frame four bights has blocked the splicing seams between end plate and side plate, and angle ring has blocked the splicing seams between box frame lower end and base plate that end plate and side plate surround, and makes end plate and side plate can along base plate Slideslip outward.
The utility model cupola well masonry expanded by heating or be subject to plumbous molten mass infiltration strengthen expand time, housing outside it can Slideslip outward accordingly, doing so avoids the defect that cupola well is out of shape and masonry is raised that the fixed shell structure of prior art exists, improve safety in utilization and life cycle.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is that A in Fig. 1 is to schematic diagram.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model discloses a kind of housing refined outside plumbous side-blown converter cupola well masonry, comprise base plate 1, end plate 2 and side plate 3, two end plates 2 and biside plate 3 surround box frame and are placed on base plate 1.
The outside of end plate 2 is furnished with some gussets 4 in the horizontal direction, and the length of gusset 4 is greater than the length of end plate 2, and its two ends symmetry offers slotted hole along its length.
Each gusset 4 place on the corresponding end plate 2 in outside of side plate 3 is furnished with horizontal gusset 5, and the length of horizontal gusset 5 is less than or equal to the length of side plate 3, and its two ends symmetry offers circular hole.
Connect by connecting attachment strap 6 between adjacent gusset 4 and horizontal gusset 5.Connect that gusset 4 link of attachment strap 6 has slotted hole along its length, horizontal gusset 5 link has circular hole, two pieces connect the link that attachment strap 6 clamps two gussets and are bolted.
Adjacent end plate 2 and side plate 3 overlap interior angle place and are fitted with angle steel 7 along short transverse, and the length of angle steel 7 is consistent with the length of end plate 2 and side plate 3, welding with end plate 2 or side plate 3 of angle steel 7, and another side and corresponding end plate 2 and side plate 3 are freely fitted.The lower end of end plate 2 and side plate 3 is connected by angle ring 8 with between base plate 1, and the laminating base plate 1 of angle ring 8 welds, and another side freely fits on end plate 2 and side plate 3.
When cupola well masonry expanded by heating, the structural principle that end plate 2 outwards can slide along base plate 1 with side plate 3 is as follows: end plate 2 makes end plate 2 and side plate 3 surround box frame with horizontal gusset 5 by being connected attachment strap 6 with the gusset 4 outside side plate 3, the inner connecting attachment strap 6 is connected by the bolt through circular hole with between side plate 3, on the slotted hole of its outer end and gusset 4 respective end slotted hole between be bolted, and the direction of two slotted holes is vertical, make end plate 2 and side plate 3 all can along corresponding slotted hole Slideslip outward like this; The angle steel 7 in box frame four bights has blocked the splicing seams between end plate 2 and side plate 3, and angle ring 8 has blocked the splicing seams between box frame lower end and base plate 1 that end plate 2 and side plate 3 surround, and makes end plate 2 and side plate 3 can along base plate 1 Slideslip outward.
