Technical Field
The utility model belongs to the field of steel-making devices, in particular to a converter trunnion bearing slag-blocking and slag-sliding device.
Background
The converter trunnion bearing device is an important part of converter tilting, supports the whole weight of a converter body, liquid metal, steel slag, a trunnion ring and a tilting speed reducer, and plays a role in transmitting the torque of a tilting mechanism. The installation position of the trunnion bearing device is close to the furnace body, steel slag splashing often occurs in the converter steelmaking process, although a trunnion heat-insulating plate is installed between the converter and a bearing seat for protection, gaps still exist between the trunnion and the heat-insulating plate in order to ensure the normal rotation of the trunnion, and the steel slag enters the positions near the trunnion bearing along the gaps. Long-time unclean, the slag just piles up, not only can wear and tear the trunnion body, can burn out trunnion bearing moreover and seal, enters into trunnion bearing even inside, and the trunnion bearing rolling element that wears out consequently produces great influence to trunnion bearing's life-span.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
As shown in fig. 1-2, the embodiment of the utility model relates to and provides a converter trunnion bearing pushing off slag swift current sediment device, including setting up converter trunnion 7 and the trunnion bearing 6 of setting on converter trunnion 7 in 8 both sides of converter, be provided with the last trunnion heat insulating board 4 that is located converter trunnion 7 top and the lower trunnion heat insulating board 41 that is located converter trunnion 7 below between converter 8 and the trunnion bearing 6, the one end that is close to converter trunnion 7 on going up trunnion heat insulating board 4 and the lower trunnion heat insulating board 41 all is provided with pushing off slag board 5 towards one side of trunnion bearing 6, the upper portion of trunnion heat insulating board 41 is provided with swift current sediment arc board 3 down, it is provided with upper pushing off slag arc board 1 by converter 8 one side to go up trunnion 4, converter trunnion 7 below upper pushing off slag arc board 1 on set up the lower pushing off slag arc board 2 of round.
The upper slag blocking arc plate 1 extends out along the axial direction of the converter trunnion 7, so that the covering area of slag blocking is enlarged.
The slag sliding arc plate 3 is in a semi-conical shape and can play a good role in guiding the steel slag.
Do the utility model discloses an installation: an upper slag blocking arc plate 1 is welded on the lower portion of an upper trunnion heat insulation plate 4, a lower slag blocking arc plate 2 is welded on a converter trunnion 7, a slag blocking plate 5 is welded on one side, close to a converter trunnion bearing device 6, of the upper and lower trunnion heat insulation plates 4 and 41, the gap between the upper and lower trunnion heat insulation plates 4 and 41 and the converter trunnion can be controlled within 5mm during installation, and a slag sliding arc plate 3 is welded above the lower trunnion heat insulation plate 41.
