Abstract
The utility model relates to a hole enlarging device for a support ring trunnion of a steelmaking converter. An L-shaped or T-shaped support frame is fixed on the end surface of a trunnion. The support frame is provided with a power head. The power head is connected with a boring bar. The interior of the boring bar is provided with a screw rod, and the exterior of the boring bar is provided with a cutter head. The end of the boring rod is provided with a conical sleeve, a core shaft and a fan-shaped block. As the utility model is connected with the converter into a whole, the utility model is not affected by the on-site environment when the hole is enlarged and processed, and the processing precision and the amount of feed are greatly improved. As the hole enlarging operation is carried out in the converter destruction and watering periods, the overhauling time of converter stopping is shortened.
Description
The utility model relates to steel-making converter ring trunnion Counterboring apparatus.
In STEELMAKING PRODUCTION, the slag inclusion thing of removing in the molten steel is very important to the quality that improves steel ingot.At present, most of at home converter steelmaking factory all adopts slag-blocking ball to carry out pushing off the slag." the pneumatic pushing off the slag of tap hole " technology that " VAI " proposes is to utilize the electromagnetic detection principle, the band quantity of slag in the tapping process is monitored, when the slag in the molten steel reaches the threshold value that sets, the pneumatics action, elevated pressure nitrogen is blocked tap hole, thereby reduces the band quantity of slag in the molten steel.
Adopt the penetration pipe of pneumatic shelves slag its pressurized gas pipeline of device and detection cable to pass from the gudgeon endoporus.In a single day original gudgeon endoporus does not satisfy by the needs of adorning pneumatic shelves slag device, will enlarge converter trunnion ring gudgeon endoporus.According to common way, generally all use boring machine to carry out reaming processing.Owing to be in production site operation, no matter be boring machine to be installed in also be mounted in the stove outside the stove, all can be subjected to the influence of situ production, its working accuracy is not high and the processing duration is longer.
The purpose of this utility model is: providing a kind of can improve the trunnion of converter Counterboring apparatus that working efficiency is processed in the gudgeon reaming again by site work.
A L type is set or T type carriage is fixed on the gudgeon end face by bearing gland and bolt; Unit head is installed on the carriage; In connecting, establishes by unit head the boring bar of screw mandrel peripheral hardware cutterhead; The end of boring bar is provided with tapered cover; Axle and secter pat are set in the tapered cover.
Because boring device is installed in converter outside, gudgeon be work piece be again the Equipment Foundations of Counterboring apparatus, form one with Counterboring apparatus.Therefore, can not be subjected to the influence of in-situ production environment, can process with bigger amount of finish.During converter is ruined stove and is fetched water, just can carry out reaming processing to gudgeon, thus shortened the left alone without help stove repair time greatly, thus economic benefit increased.
Accompanying drawing 1 is a main TV structure synoptic diagram of the present utility model;
Accompanying drawing 2 is boring bar partial enlarged drawings of accompanying drawing 1;
Accompanying drawing 3 is the utility model carriage and gudgeon connection portion master's pseudosection;
Accompanying drawing 4 is the utility model boring bar end tapered nested structure master pseudosections.
Side at converter trunnion ring 12 gudgeons 2 is provided with a L type or T type carriage 1, be fixed on the gudgeon end face 13 by bearing gland 3 and bolt 14, be connected as a single entity with converter 15, unit head 4 is installed on the carriage 1, the boring bar 5 of establishing screw mandrel 7 peripheral hardware cutterheads 6 in unit head 4 connects stretches into gudgeon endoporus 11.The end of boring bar 5 is provided with tapered cover 8.Axle 9 and secter pat 10 are set in the tapered cover 8.
Unit head 4 rotates, and drives boring bar 5, cutterhead 6, the few poor tooth transmission of screw mandrel 7 employings.Cutterhead 6 moves as length feed along 5 of boring bars under the screw mandrel 7 of boring bar 5 drives, and finishes reaming processing with boring bar 5 rotations.The other end of boring bar 5 is provided with tapered cover 8, and when the axle 9 in the tapered cover 8 was subjected to axial force, secter pat 10 will move along the inclined-plane of axle 9, and radially swelling is in gudgeon endoporus 11.
