Abstract
The utility model provides the large lock of a kind of main trough of blast furnace to repair mould, is made up of fence, slideway and baffle plate; The side minor face of rectangle fence is welded with a slideway with angle steel, and slideway both sides are equipped with one piece of baffle plate respectively, and overlapping overlap joint is taked in two pieces of baffle plate connection portions.During repairing, fence is inserted in iron runner passageway, great Zha bottom without slideway side, according to the width of width adjustment two pieces of baffle plates wanting mend ditch, then at baffle plate with import fire-resistant pouring material between lock greatly, with the fire-resistant pouring material of instrument tamping, can put into production after oven dry.The utility model can carry out Rapid-Repair to large lock online, thus stop to wash away that erosion seriously causes due to large lock cross slag phenomenon, the iron ladle surface skull avoiding slag to cause, and two asymmetry problems that tap a blast furnace effectively preventing from blast furnace to be forced to change iron mouth causing, ensure blast fumance continuously and direct motion.
Description
Technical field
The utility model belongs to blast furnace and repairs fixture fields, particularly relates to a kind of repairing mould for the large lock of main trough of blast furnace.
Background technology
Blast furnace casting is the final purpose of blast-furnace smelting, it is that slag iron flows out together from iron mouth that modernized blast furnace goes out iron process, then through fecal iron separator, the slag sluicing system that iron mouth flows out is opened, slag flows to sluice by slag runner, and molten iron flows into iron ladle by iron runner, pendulum mouth to carry out making steel or other art breading." large lock " is the significant points being separated slag iron, and it is built by pouring material to form.To wash away by slag iron for a long time due to large lock and high temperature materialization is corroded, very easy breakage causes the pig iron to cross slag, if molten iron band slag will be made to flow into iron ladle once large lock leaks slag, not only affect tank state, bits also can form skull on iron ladle surface, cause steelmaking slag to rise, iron ladle is skimmed and is caused unnecessary ton steel cost to raise.More seriously cross slag once iron runner and seriously just again build tap drain with regard to likely causing tap drain iron influx not arrive, its consequence is that blast furnace is forced to change iron mouth, causes two to tap a blast furnace asymmetric, has a strong impact on smooth operation of furnace and serialization High-efficient Production.
Summary of the invention
The utility model aim to provide a kind of prevent large lock from washing away erosion seriously causes crosses slag phenomenon, mould repaired by the large lock of main trough of blast furnace that slag causes iron ladle surface skull and blast furnace to change iron mouth accident to avoid iron runner to cross.
For this reason, the solution that the utility model is taked is:
Mould repaired by the large lock of a kind of main trough of blast furnace, it is characterized in that, is made up of fence, slideway and baffle plate; The side minor face of rectangle fence is welded with a slideway with angle steel, and slideway both sides are equipped with one piece of baffle plate respectively, and overlapping overlap joint is taked in two pieces of baffle plate connection portions.Two pieces of baffle length after overlap joint are identical with the main iron hook width at place to be repaired.
Using method of the present utility model and beneficial effect are:
When finding that the large lock breakage of fecal iron separator needs to repair, do not had by fence slideway side to insert in iron runner passageway, great Zha bottom, depth of penetration is the distance between slideway and large lock, namely needs the thickness repairing large lock.According to the width of width adjustment two pieces of baffle plates wanting mend ditch, the width of such as ditch is 900mm, and two pieces of barrier width are also adjusted to 900mm; Then between baffle plate and large lock, import fire-resistant pouring material, with the fire-resistant pouring material of instrument tamping, can put into production after oven dry.
The utility model can be repaired being subject to washing away the damaged easy large lock crossing slag of erosion online, and the time of repairing is fast, the repairing to large lock just can be completed when another connects an iron, often repair and once can guarantee that large lock normally produces 7 ~ 8 days, that can stop that large lock washes away that erosion seriously causes crosses slag phenomenon, the iron ladle surface skull avoiding slag to cause, be conducive to improving molten steel quality, and two asymmetry problems that tap a blast furnace that can effectively prevent from blast furnace to be forced to change iron mouth causing, ensure blast fumance continuously and direct motion.
Accompanying drawing explanation
Fig. 1 is that mould structure schematic diagram repaired by large lock.
In figure: fence 1, slideway 2, baffle plate 3.
Embodiment
As seen from Figure 1, mould repaired by the large lock of the utility model main trough of blast furnace, is be made up of fence 1, slideway 2 and two pieces of baffle plates 3.The rectangular frame that fence 1 adopts 6mm Plate Steel to be welded, its dimensions is 1300 × 750 × 180mm, and the left side minor face of fence 1 is welded with a slideway 2 with 40# angle steel, and the width of slideway 2 is slightly larger than the thickness of 2 pieces of baffle plates 3.The both sides of slideway 2 are equipped with the baffle plate 3 of one piece of high 100mm, long 500mm respectively, two pieces of baffle plates 3 take the overlapping mode connection that partly overlaps, two pieces of baffle plate 3 length after overlap joint are identical with the main iron hook width at place to be repaired, the main iron hook width at place to be repaired is 900mm, then two pieces of baffle plate 3 lap width are 50mm.
Claims (2)
