Description
Technical field
The present invention relates to metallurgical mine comprehensive utilization of tailing field, particularly a kind of complete processing of applying grid processing residual casting slag.
Background technology
In variety steel smelting process, in order to ensure the cleanliness factor of molten steel, conventionally can residual part casting residual molten steel in ladle.This part casting residual molten steel and slag are together introduced into slag ladle, condense into residual casting slag after cooling to cut or polish jade with an emery wheel.Along with the expansion of steel kind and the development ，Ge steel mill of Clean Steel technology have firmly all become the integral part of the supporting residues processing technique of extremely important smelting with slag processing system, basic demand is that fast, the large ability of producing of processing rhythm is strong.But due to residual casting slag process mutually intersect with the utilization of bulk slag steel (iron), inseparable, technical process is longer, daily organization of production is also very complicated, often because processing the normal production of impact not in time.
Therefore, domestic Ge great steel mill is specially when having the supporting production plant that drops hammer, open up the broken processing space of recycling of bulk slag steel, and adopt the off-line processing treatment methods such as oxyacetylene metal-cutting hammering method and explosion hammering method, further to enter stove requirement by steel scrap, fragmentation, cutting, processing treatment, make every effort to whole recyclings of slag iron and steel resource in residual casting slag.
Residual casting slag is processed the efficient circulation of the large slag steel producing and is utilized difficult problem, is mainly reflected in three aspects: the one, and the Production Flow Chart of broken complete processing off-line is extremely long, causes processing efficiency extremely low, and cost is high; The 2nd, processing crushing process tradition falls behind, and security incident easily occurs or have serious production safety hidden danger; The 3rd, the dense smokes such as gas cutting have caused big factors and the problems such as serious environmental pollution and resource loss.
Summary of the invention
For addressing the above problem, the invention discloses a kind of complete processing that grid is processed residual casting slag of applying.
In order to achieve the above object, the invention provides following technical scheme: a kind of complete processing of applying grid processing residual casting slag, comprises the following steps:
(1) carry out the assembling of grid;
(2) residual casting slag tank is sprayed, after spraying is good, carry out drying pot;
(3) after residual casting slag tank drying pot, padding slag processes;
(4) by driving, slag ladle is hung to grid installation place, carry out the lifting of grid;
(5) slag ladle that presets grid is transported to and specifies under stove, wait for deslagging;
(6) the residual casting slag tank of good slag being transported to appointed place carries out cooling;
(7) cooling good residual casting slag tank being transported to slag processes across turning over fallers hammer between dropping hammer;
(8) with Cinder crusher, steel more than the casting of dropping hammer is carried out to slag hitting, remove the scum silica frost on the remaining steel of casting surface;
(9) with magneticchuck, the residual casting slag to dropping hammer, after slag hitting carries out selectedly, further improves the purity of the remaining steel of casting, directly returns STEELMAKING PRODUCTION;
(10) residue tailings is transported to converter slag sorting line and carries out sorting, by screening magnetic separation process, fully reclaims ferrous metal in tailings.
As a modification of the present invention, described grid is comprised of the flase floor that is isosceles trapezoid shape, and described flase floor comprises that three bottoms are provided with the Under The Grille plate of slot and the upper flase floor that three top is provided with slot.
As a modification of the present invention, the thickness of described slag ladle pad slag is 210-230mm.
As a modification of the present invention, in described step (6), the cooling time is 8 hours.
The invention has the beneficial effects as follows:
Application grid disclosed by the invention is processed the complete processing of residual casting slag, by to by the preset slag ladle of the grid assembling, carry out liquid state and award slag fusion, by grid, cut apart separation, finally realize nature and disintegrate, avoided the generation of " large slag ", promoted the use of grid new technology, more contribute to strengthen large slag steel recycle level and ability, greatly promoted slag and processed and the economic and technique level fully utilizing, avoided the pollution of environment and avoided causing space waste.By setting, be the sliceable grid of isosceles trapezoid shape, can be convenient to the installation of grid and the making of grid, by remaining in slag ladle just having been turned over to fallers hammer, remove the remaining steel surface recrement of casting and the magneticchuck residual casting slag to dropping hammer, after slag hitting and carry out selectedly, improved the utilization ratio of iron and steel.

Embodiment
Below with reference to specific embodiment, technical scheme provided by the invention is elaborated, should understands following embodiment and only for the present invention is described, is not used in and limits the scope of the invention.
A kind of complete processing of applying grid processing residual casting slag as described in Figure 1, comprises the following steps:
(1) carry out the assembling of grid, grid is comprised of the flase floor that is isosceles trapezoid shape, described flase floor comprises that three bottoms are provided with the Under The Grille plate of slot and the upper flase floor that three top is provided with slot, and the slot by upper flase floor and Under The Grille plate is spliced;
