Abstract
The invention relates to a replacement method of a converter slag trap, which comprises the following steps: moving a slag wagon provided with a trap bin to below the slag trap to be maintained, putting the demounted slag trap to be maintained into the trap bin by using a chain hoist, and taking away the slag wagon with the slag trap to be maintained; and moving a complete slag trap to the position near the demounted slag trap by using the slag wagon, hoisting the complete slag trap to the original position of the demounted slag trap by using the chain hoist, and fixing. The method has the advantages of low cost, high safety and high speed, and is capable of enhancing the replacement efficiency of the slag trap, shortening the replacement time and reducing the participation of the maintainers; the replacement of one slag trap can be accomplished by 6 persons for 6 hours; and the method can avoid aerial work, thereby ensuring the safety of the working personnel.
Description
Technical field
The present invention relates to converter field, particularly a kind of replacing options of slag blocking plate of converter.
Background technology
In the converter lines of smelter, under stove, skimming plate plays vital effect as converter annex in smelting molten steel process.The dregs of the splashes such as fire door are in dropping process, and skimming plate changes its direction fallen, and makes dregs fall into stove slag basin, protects the building foundation facility of both sides, converter bottom simultaneously.Skimming plate under long-play can be damaged, and needs to change it.
Fig. 1 is the position view of skimming plate under Converter, and as shown in the figure, described converter 3 is arranged on converter and supports on 5, and nine meters of platforms 4 as converter producing and inspection platform are positioned at the surrounding of converter 3, have gap between nine meters of platforms 4 and converter 3.Skimming plate 1 and backplate 2 are installed in the below of converter 3.Referring to figs. 2 and 3, according to skimming plate 1 and the distance in gap between nine meters of platforms 4 and converter 3, skimming plate 1 is divided into the skimming plate 1-1 nearer with described gap and the skimming plate 1-2 away from described gap.When changing skimming plate under stove, due to the position of the building body 7 around converter, using the gap between nine meters of platforms 4 and converter 3 as hoisting port, because skimming plate 1-1 is comparatively near apart from this hoisting port, therefore by driving main hook 8, skimming plate 1-1 lifting is sent down; And skimming plate 1-2 is away from hoisting port, therefore need use jack 10 by skimming plate 1-2 from gap hoisting port level have bad luck to needs overhaul correct position.The above-mentioned upkeep operation to skimming plate 1-2 belongs to working aloft, and when manually skimming plate 1-2 jack 10 level of 2 tons heavy being had bad luck, securing band needs constantly to set out, and danger is higher, working efficiency is very low, changes one piece of skimming plate 1-2 and approximately needs 8 people 10 hours.If entirety has just changed the skimming plate of whole body of wall, then the repair time is longer.
At present, do not have a kind of low cost, substitute mode safely and fast, the replacing efficiency of skimming plate can be improved, reduce replacing construction, reduce the participation of maintainer.
Summary of the invention
The object of the invention is to overcome low, the dangerous higher defect of skimming plate replacing options efficiency of the prior art, thus a kind of replacing options of slag blocking plate of converter is provided.
To achieve these goals, the invention provides a kind of replacing options of slag blocking plate of converter, comprising:
Under the slag car being provided with baffle plate storehouse is moved to skimming plate to be repaired, by jack, the skimming plate to be repaired under dismounting is placed in described baffle plate storehouse, then removes this slag car with skimming plate to be repaired; Then intact skimming plate is moved to by the described slag car near the position of dismantling skimming plate, by described jack, this intact skimming plate is lifted into original position of dismantling skimming plate and also fixes; Wherein,
Described baffle plate storehouse is top end opening bottom end closure, vertical direction cross section three-dimensional box-like in echelon.
In technique scheme, the method comprises further:
Step 1), the slag car is when being in the slag car passage beyond skimming plate bottom, lifting baffle plate storehouse is mounted to slag car top and is connected firmly with the slag car, and converter is simultaneously shaken to horizontality;
Step 2), run the slag car and move to passage bottom converter, near the bottom of the skimming plate that need overhaul, by comprise jack, spanner, bolt equipment to be delivered to the position of skimming plate to be repaired by the slag car;
Step 3), jack is mounted to skimming plate top to be repaired;
Step 4), by jack hook connecting reception maintenance skimming plate, dismantle this skimming plate, pull jack skimming plate to be put into the baffle plate storehouse of the bottom slag car, then unclamp the connection of jack and skimming plate;
Step 5), when starting slag car passage that the slag car moves to beyond skimming plate bottom, skimming plate to be repaired is hung out baffle plate storehouse, intact skimming plate is hung in baffle plate storehouse;
Step 6), start the slag car and move to the passage dismantling skimming plate bottom, ensure that the skimming plate level attitude in baffle plate storehouse matches with the skimming plate position of dismantling;
Step 7), jack is connected intact skimming plate, pull jack intact skimming plate to be pulled to the position of dismantling skimming plate, after adjusting intact skimming plate position, fastening firm skimming plate, unclamps the connection of jack and skimming plate;
Step 8), dismounting jack, by comprising jack, the equipment of spanner bolt transports ground back by the slag car, completes maintenance.
In technique scheme, described baffle plate storehouse comprises: the first limit, storehouse, storehouse skewback, the second limit, storehouse, storehouse bottom panel; Wherein, described storehouse skewback is connected on the bottom panel of described storehouse, and angle is between the two 60 degree; The first described limit, storehouse, the second limit, storehouse are welded on storehouse skewback and storehouse bottom panel respectively, and described storehouse bottom panel is with bolt hole, and the first described limit, storehouse, the spacing on the second limit, storehouse are slightly larger than the width of the skimming plate that will change.
The invention has the advantages that:
Method low cost of the present invention, safely and fast, the replacing efficiency of skimming plate can be improved, reduce replacing construction, reduce the participation of maintainer, often change one piece of skimming plate, only need 6 people can complete for 6 hours, and can working aloft be avoided, ensure the safety of staff.
