Abstract

The invention relates to a connecting device for a converter backing ring and a furnace shell. The connecting device for the spherical hinge slider type converter backing ring and the furnace shell comprises three connecting units, wherein each connecting unit comprises a hanging disc, a big ear base, a supporting shaft, a sliding sleeve and a spherical hinge shaft; the hanging disc comprises a backing ring welded on the furnace shell and rib plates radially arranged around the backing ring; the rib plates are respectively welded with the backing ring and the furnace shell; the big ear base is positioned under the backing ring and is fixedly connected to the backing ring; the big ear base is provided with a sliding sleeve through hole; the sliding sleeve is arranged in the sliding sleeve through hole; an external end of the supporting shaft is fixed with the sliding sleeve; an interior end of the supporting shaft is the shaft shoulder; the interior of the supporting shaft is fixedly connected to an inner ring of the spherical hinge shaft; the spherical hinge shaft is outside of the shaft shoulder; and the outer ring of the spherical hinge shaft is fixed with the backing ring. The connecting device of the invention is characterized by simple and reliable structure, bearing static determinacy of furnace shell and capability of improving bearing condition.

Description

technical field [0001] The invention relates to a connection device between a converter support ring and a furnace shell, which is applied in the technical field of converter steelmaking equipment, or the technological requirements of other similar smelting furnaces. Background technique [0002] The connection device between the converter shell and the supporting ring is an important part of the converter equipment, through which the supporting ring can drive the furnace shell to rotate to complete the operations of charging, sampling, temperature measurement, slag tapping and steel tapping in the steelmaking process. Therefore, the connection device should be able to ensure that the furnace shell load can be transferred to the support ring when the converter is at any tilting position, and maintain the correct position of the furnace shell in the support ring, and at the same time be able to adapt to the expansion of the furnace shell in the axial and radial directions. , ...
