Description

A kind of converter water-cooled backing ring device

Technical field:

The utility model relates to the smelting equipment technical field, particularly relates to a kind of converter water-cooled backing ring device.

Background technology:

Converter trunnion ring is important carrying and the drive disk assembly in the metallurgical converter equipment, when work, to bear the thermal load of static load, dynamic load and thermal radiation, thermal conduction generation, working conditions is very abominable, in the converter production practice, the major cause that thermal load normally causes backing ring to lose efficacy is a converter trunnion ring refrigerative main purpose so reduce the suffered thermal load of backing ring.The present existing converter trunnion ring type of cooling is a lot, mostly adopt water-cooling pattern to cool off reducing thermal load, but cooling performance has nothing in common with each other.Because the water-cooled process can produce part vapour (gas) body, if untimely discharge can accumulate in the backing ring, influence the backing ring cooling performance, produce more thermal load, present water-cooled backing ring mostly can't be discharged this part vapour (gas) body timely and effectively, so that has influenced the work-ing life of converter trunnion ring.

Summary of the invention:

The purpose of this utility model provides a kind of converter water-cooled backing ring device, by the improvement to converter water-cooled backing ring structure, makes the smooth and easy discharge of vapour (gas) body that produces in process of cooling, improves the cooling performance of converter trunnion ring, improves the work-ing life of converter trunnion ring.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of converter water-cooled backing ring device is provided, mainly form by cover plate, cover plate two, gudgeon, inner ring, outer ring, central dividing plate, dividing plate one, dividing plate two, cover plate, cover plate two, inner ring, outer ring and gudgeon are welded into the body structure of backing ring, feature is: the central dividing plate that has a plurality of water flowing circular holes is welded on the body structure position intermediate, and body structure is divided into two portions up and down; Dividing plate one and the staggered respectively both sides that are welded on central dividing plate up and down of dividing plate two are divided into a plurality of cavitys with casing, and each cavity all comprises the water flowing circular hole of a central dividing plate; Automatic exhaust steam valve is installed on the cover plate, riser welds with cover plate two and gudgeon respectively, the gudgeon both sides are separated into two obstructed each other cavitys, the gusset that has the water flowing circular hole is welded between gudgeon and the cover plate two, L shaped pipe is connected with the gudgeon prosopyle, its opening part is pressed close to cover plate, and gusset and riser are installed in the gudgeon groove fixedlys connected with gudgeon; Its feature also is: the blocking technological holes that a plurality of blind plates are opened during with dividing plate one, dividing plate two and cover plate and inner ring, the welding of outer ring side plate; Blind plate has the ventilation aperture near close cover plate up and down; As the L shaped tube opening of cooling-water duct up, its mouth of pipe height next-door neighbour cover plate; One section that inserts the gudgeon case on the gudgeon be groove-shaped that two diameter is big, mid-diameter is little, is fixedly mounted on the M shape structure of gusset and riser and gudgeon formation embedding in the groove on the gudgeon.

The beneficial effect of this utility model is: owing to adopt L shaped pipe and automatic exhaust steam valve, in time discharge vapour (gas) body that process of cooling produces, reduce the backing ring thermal load, improved the cooling performance of converter trunnion ring, owing to adopt the porous shape alternating structure of intermediate plate and dividing plate, make cooling-water flowing in backing ring, form the wave pattern of heaving and dipping, improve the heat exchange efficiency of water coolant and backing ring body, strengthened cooling performance and prolonged work-ing life of converter trunnion ring.
