Abstract
The invention relates to a quick replacement device for a water-cooled discharge duct. The adopted technical solution is that the quick replacement device is made of steel plates which are 30 mm thick and are of Q235 and Q345 in material. A shaping dimension is thickness 30 mm * width 30 mm * length 50 mm, and vertical bar steel pressing plates which are 35 mm wide, 20 mm thick and 50 mm long and triangular wedge plates which are 30 mm thick are welded; during installation, six groups of pressing plates are preassembled and welded, and are fixed by six triangular wedge plates, and sealing is performed by matching with an asbestos cord, therefore the selection is completed. The quick replacement device disclosed by the invention has the beneficial effects of being convenient, rapid, simple to manufacture and low in cost; disassembly and assembly time can be shortened to about 1 hour, labor strength of a worker is reduced, and the repair and maintenance requirement of a converter is absolutely met.
Description
Art
The present invention changes water-cooled tremie pipe to realize fast, designs and produces for more tap to tap time are saved in steel-making. Adopt Q235, Q345 steel plate, it pre-assembled is fixed on movable sections flue, reduce welding job amount, directly water-cooled tremie pipe is fixed more fast, it is achieved change fast.
Background technology
Before the present invention comes into operation, installing water-cooled tremie pipe needs to weld, and welding job amount is relatively big, needs gas welding to cut during dismounting. Such as replacing tremie pipe, only removing and install water-cooled tremie pipe just needs 3��4 hours, and labour intensity is big, and waste of material is serious.
Summary of the invention
Change water-cooled tremie pipe in process of production waste a large amount of production times and manpower and materials and this difficult problem of material to solve, the present invention adopts pre-assembled pressing plate to coordinate wedge to be fixed the mode of tremie pipe, can effectively reduce the erosion of large cover, shorten the settling time, reduce labor strength.
The technical solution used in the present invention is: adopt the steel plate that 30mm is thick, material is Q235, Q345 to make by oneself and become. Compact dimensions is that 30mm is thick, and the long 50mm of wide 30mm* is welded with the vertical muscle pressing plate of the wide 35mm* long 50mm of thick 20mm* and thick three angle wedge plates of 30mm. Adopt six groups to carry out pre-assembled welding pressing plate during installation, it is fixed by six three angle wedge plates, and coordinates asbestos twine to close.
The invention has the beneficial effects as follows: convenient, fast, making simple, cost is low. Disassembly and assembly time can be shortened to 1 hours, reduce labor strength, meet the repair and maintenance demand of converter completely.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is little wedge construction drawing
Fig. 2 is the construction drawing of pressing plate
Fig. 3 is scheme of installation of the present invention
Embodiment
Q235, Q345 steel plate is adopted to make.
Adopt 30mm thick, material be Q235, Q345 steel plate self-control and become. Compact dimensions is that 30mm is thick, and the long 50mm of wide 30mm* is welded with the vertical muscle pressing plate of the wide 35mm* long 50mm of thick 20mm* and thick three angle wedge plates of 30mm. Adopt six groups to carry out pre-assembled welding pressing plate during installation, it is fixed by six three angle wedge plates, and coordinates asbestos twine to close. Complete this selection.
Claims (3)
1. realize the invention that converter water-cooling tremie pipe is changed fast, comprising: permanent sleeve, trilateral wedge two portions. It is characterized in that: steel plate that adopt 30mm thick, that material is Q235, Q345 is made by oneself and become. Compact dimensions is that 30mm is thick, and the long 50mm of wide 30mm* is welded with the vertical muscle pressing plate of the wide 35mm* long 50mm of thick 20mm* and thick three angle wedge plates of 30mm.Adopt six groups to carry out pre-assembled welding pressing plate during installation, it is fixed by six three angle wedge plates, and coordinates asbestos twine to close.
2. structure according to claim 1, is characterized in that utilization positioned with coordinating of water-cooled tremie pipe, it is ensured that accurately fix.
3. pressure plate structure according to claim 1, is characterized in that utilizing trench structure to coordinate with minor flaps, pre-welding movable sections tremie pipe position, it is possible to accurately ensure its firmness, and convenient and swift, and cost is lower.
