Description
Technical field
The present invention relates to steel slag production application technical field, specially a kind of steel slag production line proposes production method.
Background technique
Steel slag is one of steelmaking process byproduct, it is by impurity such as silicon, manganese, p and s in the pig iron in fusion process
The salt that various oxides and these oxides made of middle oxidation are generated with solvent reaction is formed, contain in steel slag there are many
Useful component: metallic iron 2%~8%, calcium oxide 40%~60%, magnesia 3%~10%, manganese oxide 1%~8%, therefore can
It is used as Ferrous Metallurgy raw material, the mineral composition of steel slag is based on tricalcium silicate, followed by dicalcium silicate, RO phase, ferrous acid two
Calcium and free calcium oxide, steel slag are clinker, are remelting phases, and fusion temperature is low, and when refuse, liquid phase forms morning, good fluidity,
Steel slag is divided into electric furnace slag, open hearth steel slag and 3 kinds of converter slag, and country's steel slag main process has at present: hot application method, wind quenching
Method, drum process, granulating wheel method and the bored method of heat, wherein hot application method, drum process and the bored method of heat are the most commonly used.
For steel slag as secondary resource comprehensive utilization there are two main path, one is sharp in our factory's circulation as solvent is smelted
With not only can replace lime stone, and can therefrom recycle a large amount of metallic iron and other useful elements；The other is as system
The raw material for making road-making material, construction material and agricultural fertilizer, with the development of the production model of 2+3, at the former steel slag formulated
Science and engineering skill and the slag processing equipment of design are not able to satisfy existing steel slag yield, in order to be effectively improved slag processing ability
Problem improves slag processing amount and reduces ton Slag treatment cost, it is necessary to production technology and production equipment optimized,
Output can not only be improved can reduce production cost again, so propose a kind of steel slag production line proposes production method to solve among the above
The problem of proposed.

40 °, screening installation is mounted on 1# skin fortune machine inlet, is sent steel slag on screening installation using load wagon and excavator, under sieve
Object enters broken production equipment to finishing operation, oversize by load wagon and excavator be sent to weight fracture area concentrate it is broken
It is broken, the step is repeated after broken and is screened, and screening is not repeated brokenly by entering broken production equipment by person
It is broken, the step for mainly make steel slag screening installation, screenings enters broken production equipment, and oversize returns back to weight fracture area
It carries out being again introduced into screening installation after being crushed, in order to the whole uniformity of steel slag；
3) it adjusts equipment and is transported, 1# belt conveyer is increased into bandwidth 800mm by original bandwidth 650mm,
29.5 meters of Pi Yunji overall length, tail wheel φ 630 uses spiral fastening, and great wheel category driving wheel φ 630 is matched using cylindrical gear reducer
Set 15 kilowatt motors driving, 1# belt fortune tail wheel at increase a motor oscillating batcher according to crusher processing capacity control to
Doses, 2# belt conveyer increase to bandwidth 800mm by original bandwidth 650mm, and 18.5 meters of overall length, tail wheel is using outside φ 600
Dress formula motorized roller, great wheel use 600 permanent magnetic pulley of φ, and tension mode uses vertical counter-weight, all Pi Yunji spare parts and three benefits
It is unified that new district 800mm bandwidth travelling belt unanimously ensures spare part, and then makes 1#2# belt conveyer because being transformed dilatation, thus
Meet and carrys out Slag treatment ability；
4) electromagnetism belt iron dressing machine is removed fixed bracket by secondary adjustment equipment, whole to translate 100mm to great wheel direction,
Magnetic force range is kept and 2# Pi Yunji glue surface 350mm distance, and mouth increases a motor oscillating batcher elimination slag under slag steel chute
Steel scratches the factor of travelling belt, transports steel slag after adjustment, after replacing electromagnetism belt iron dressing machine and again fixed
Position, and mouth increase batcher can eliminate the factor that slag steel scratches travelling belt under chute；
5) what transformation finished proposes production effect, and the production place of production is on the basis that original production ability is 1.66 ten thousand tons/month after transformation
On be promoted to 2.2 ten thousand tons/month, and can monthly handle steel-making completely and ironmaking carrys out slag, and can Processing for removing generate not in time
Steel slag accumulation, 45% or more magnetic separation slag steel iron content, 50% or more fine slag iron iron content.
(3) beneficial effect

Range is kept and 2# Pi Yunji glue surface 350mm distance, and mouth increases a motor oscillating batcher elimination slag steel and draws under slag steel chute
The factor for hurting travelling belt, transports steel slag after adjustment, after replacing electromagnetism belt iron dressing machine and relocates, and
Mouth, which increases batcher, under chute can eliminate the factor that slag steel scratches travelling belt；
5) what transformation finished proposes production effect, and the production place of production mentions on the basis of original production ability is 1.66 ten thousand ton/month after transformation
2.2 ten thousand tons/month are risen to, and can monthly handle steel-making completely and ironmaking carrys out slag, and can the steel slag that generates not in time of Processing for removing
Accumulation, 45% or more magnetic separation slag steel iron content, 50% or more fine slag iron iron content.
