Abstract
The invention discloses a method for treating desulfuration slag through a grating. According to the method, the assembled grating is placed in a desulfuration slag tank in advance, liquid slag pouring is conducted, segmentation or separation is conducted through the grating, and finally, natural segmentation is realized, so that production of 'large slag blocks' is avoided; and residual steel slag after treatment can also be used as a raw material for machining grating prefabricated panels and can be recycled. By the aid of the method, the level and the capability of recycling of slag steel can be strengthened, the efficiency of slag block treatment and the comprehensive utilization level are greatly improved, and environmental pollution and space waste are reduced.
Description
Technical field
The treatment process that the present invention relates to desulfurization slag, desulfurization slag is cut apart separation by grid, finally realizes nature and disintegrates, and has avoided the generation of " large slag ", has promoted the level of comprehensive utilization of slag, has avoided the pollution of environment and has avoided causing space waste.
Background technology
Along with the development of Iron And Steel Industry, slag amount also increases thereupon.At present, desulfurization slag Technology of Steel Slag Processing has many, be exactly the most directly that hot melt slag is after the quenching of fetching water processed, with shovel loader, drop hammer, the equipment such as Cinder crusher, power shovel excavates entrucking, be transported to again Dumping Sites, in this way, storing up of desulfurization slag not only takies a large amount of arable lands, contaminate environment, and in slag, also has the iron of callable 20-40% to waste.
In prior art in cold steel scoria processing method, processed uncured moistening cold slag and directly pour diagrid into and sieve, the clinker that is greater than 300mm drops hammer after processing and loops back diagrid through screening; The clinker that is less than 100mm falls within on transfer roller, through belt tramp iron separator, removes surperficial iron content, enters trommel screen and screens; The clinker that is greater than 100mm enters crusher and carries out fragmentation, and the vibratory screening apparatus of delivering to of 0-30mm screens.
And the object that desulfurization slag is processed is all to extract metalliferous material, clinker wherein cannot be processed, and can only stack and bury, and such processing has not only caused waste, and the metalliferous material in clinker cannot be separated fully with slag former, for the production of iron and steel enterprise has brought very large waste.
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 iron, and adopt the off-line processing treatment methods such as oxyacetylene metal-cutting hammering method and explosion hammering method, by steel scrap, enter stove requirement, carry out fragmentation, cutting, processing treatment, make every effort to whole recyclings of slag iron resources in desulfurization slag slag.
The efficient circulation of the large slag steel that desulfurization slag process to produce is utilized difficult problem, is mainly reflected in three aspects: the one, and desulfurization slag the quenching weak effect of fetching water, easily forms large slag in slag ladle bottom; The 2nd, the Production Flow Chart of broken complete processing off-line is extremely long, causes processing efficiency extremely low, and cost is high; The 3rd, processing crushing process tradition falls behind, and general disintegrating apparatus is difficult to meet the processing requirements of bulk slag stone roller, causes a large amount of slag iron to stick together and cannot utilize, and can only store up.
Summary of the invention
For addressing the above problem, the invention discloses a kind of method that grid is processed desulfurization slag of applying, by to the preset grid assembling in desulfurization slag slag ladle, desulfurization slag is divided into several aliquots, desulfurization slag is naturally diminished in slag ladle, prevent that " large slag " produces, fetch water again quenching, with magneticchuck, sort after turning over fallers hammer, remove the scum silica frost on slag steel surface, finally with magneticchuck, carry out selected, improve the purity of slag iron block, meet the requirement of returning production.
