With continued reference to fig. 1, another embodiment of the present application also provides a slag-proof device for a converter bearing seat, which is applied to a converter. The slag-proof device of the converter bearing seat comprises a slag-stopping cover 4 and a protection plate 5, wherein the slag-stopping cover 4 is in an inverted funnel shape and covers the furnace body 1, and the small-opening end of the slag-stopping cover 4 is positioned at the furnace mouth of the furnace body 1. The center of the protection plate 5 is provided with a central hole which is sleeved on the trunnion 2 and is fixedly connected with the furnace body 1; the protective plate 5 is intersected with the slag blocking cover 4, the intersection line adopts welding sealing connection, and a welding line completely covers the radial direction of the trunnion 2. Keep apart slag and furnace body through pushing off the slag cover 4 for the slag is along pushing off the slag cover 4 whereabouts, and with guard plate 5 and 4 welded seal of pushing off the slag cover, make the slag of whereabouts drop along the welding seam, can not fall on trunnion 2 and bearing frame 3, consequently the slag can not follow trunnion 2 and get into bearing frame 3, and the pushing off the slag is effectual, can effectually carry out the separation to the slag, prevents the destruction of slag to the bearing, thereby plays fine guard action to the bearing, ensures the normal production of converter.
It is understood that the weld completely covers the radial direction of the trunnion 2 means: when the furnace body 1 furnace mouth is up, the orthographic projection of the welding seam is required to completely cover the width of the corresponding position of the trunnion 2, and the steel slag is required to be completely blocked.
In some specific embodiments, the protection plate 5 is welded with the furnace body 1 and the slag blocking cover 4 through the connecting section steel 7, the section steel has strong deformation prevention capacity, and the protection plate 5 can be prevented from being displaced and deformed due to insecure connecting pieces.
In some specific embodiments, the welding seam completely covers the radial direction of the central hole of the protection plate 5, so that the welding seam is as wide as possible, steel slag discharged along the welding seam can be further far away from the trunnion 2, and a better protection effect can be achieved.
Further, the upper part of the slag bridge 4 is a conical section, the lower part of the slag bridge is a cylindrical section, and the conical section and the cylindrical section are intersected with the protection plate 5 and are welded in a sealing mode. Therefore, the welding seam is in an inverted U shape, the upper part and two sides of the trunnion 2 are protected, so that the steel slag can not enter the trunnion 2 completely, and a further protection effect can be achieved.
Referring to fig. 2, in some embodiments, a hub-shaped steel skeleton 8 is disposed on one side of the protection plate 5, and the steel skeleton 8 can reinforce the protection plate 5 to prevent the protection plate 5 from deforming.
With continued reference to fig. 2, in some embodiments, the protection plate 5 is circular, which saves more material and reduces the overall weight.
With continued reference to fig. 2, in some embodiments, the slag-proof device of the converter bearing seat further includes a protective cover 6 for the protection plate 5. Specifically, the protection cover 6 can be installed on the inner wall of the dog house, and the protection cover 6 covers the edge of the protection plate 5, so that the protection cover can be prevented from overflowing from the edge of the protection plate 5 and falling onto the trunnion 2 again, and the protection grade is improved.
Referring to fig. 2, in some embodiments, the protective cover 6 may be a semicircular ring, and is installed on the inner wall of the passing room, and covers the edge of the protective plate 5 located on the furnace mouth side of the furnace body 1, and compared with the semicircular ring, the steel slag is from top to bottom, so that the protective effect is the same, and the material is saved; and steel slag can be accumulated on the lower half part of the whole circular ring.
Referring to fig. 3, in some embodiments, the hood 6 is mainly composed of a top panel 9 and side panels 10. The top plate 9 is in a semicircular arc shape, the side plate 10 is in a semicircular ring shape, the top plate 9 and the side plate 10 are arranged concentrically and are connected in a welding mode, and the whole section of the top plate is in an L shape. The top plate 9 is over against the side surface of the protection plate 5, and the side plate 10 is over against the bottom surface of the protection plate 5 facing the furnace body 1. A labyrinth is formed by matching the top plate 9, the side plate 10 and the protective plate 5, so as to block the steel slag.
It can be understood that, when the protection cover 6 is circular, the whole protection cover can be regarded as a cylinder, the side surface of the protection plate 5 is the side surface of the cylinder, and the bottom surface of the protection plate 5 is the bottom surface of the cylinder.
In conclusion, in the actual converter smelting and production process: when the converter blows, the slag and the granular steel splashed from the converter mouth slide down between the protective plate 5 and the slag blocking cover 4 along the slag blocking cover 4; when the converter is shaken, high-temperature slag and granular steel can slide to the ground from the front of the converter and the back of the converter; some cooled slag stays in a containing area between the protection plate 5 and the slag blocking cover 4, and the slag can be cleaned regularly due to the large (higher) containing area, so that the excessive accumulation of the slag is avoided. In addition, if the slag is accumulated too much, the labyrinth structure between the protection plate 5 and the protection cover 4 can block the slag and the granular steel for one time; in addition, the dog house can further stop the slag and the grain steel once again, and the slag and the grain steel are prevented from entering the bearing seat 3, so that the sealing slag-stopping effect is improved, and the damage to the normal operation of equipment is avoided.
