Technical Field

The invention relates to the technical field of steel smelting, in particular to a vertical casting machine, an alloy molten iron granulating system and an alloy molten iron granulating method.

Background

The grain size of the ferroalloy used in the steel making process is generally 10 to 60 mm. The current production methods of ferroalloys with such particle sizes include the following:

(1) Casting pit layer casting: the two casting pits are used in turn, and the casting pits are surrounded by thick and large cast iron blocks. After the first casting pit is full, the ferroalloy is shoveled by a loader and is transported to a transport vehicle to be transferred to a jaw crusher for crushing and screening, and the particles meet the contract requirements of bagging and packaging and are not qualified or are sold at low cost or are remelted in a furnace. The smaller ferroalloy enterprises adopt a large ingot mould or a sand pit to cast liquid ferroalloy into a large iron ingot with the single weight of about 2000kg, and after cooling, the liquid ferroalloy is manually deslagged, impurity removed and crushed into particles with the particle size of 10-60 mm. There are five major problems: firstly, the alloy has high pulverization rate, and the unqualified powder is usually 5 to 20 percent; secondly, the process is long, the labor productivity is low, and the quality is difficult to control; secondly, the time from tapping to packing lasts for more than 2 days, and an enterprise producing 1000 tons of alloy per day needs about 500 persons to carry out finishing and crushing, so that the labor cost is high, and the time consumption is long; thirdly, the environmental pollution is serious, and the iron alloy forms a big mushroom cloud direct-flushing blue sky along with high-temperature heat waves due to high-concentration dust generated by the contact of the ingot mold coating and high-temperature molten iron during casting, so that the environmental pollution and the atmosphere are serious; fourthly, the casting workshops are dirty, messy and hot, the whole workshop is a ladle, refractory materials, a sand mold or an ingot mold, coating and the like which are used all at present, and most of the casting workshops of enterprises have no qualified safety channel and have serious potential safety hazards; fifthly, in the processes of slag skimming, casting and finishing, workers must work at the environmental temperature of 1500-300 ℃, and the working environment is severe.

(2) Casting by a belt casting machine: the molten iron was continuously cast using a belt caster and then manually crushed. The method is that a flat plate type ingot mould for casting is arranged on a belt type machine, a motor drives a chain to rotate after speed reduction, and the mould arranged on a transmission belt continuously moves along with the chain. When the device is used, the belt casting machine is started, the crane is used for hoisting and conveying the molten iron to a casting station or a tipping device, the molten iron in the ladle is slowly injected into an ingot mould on a continuously moving transmission belt or is introduced into the casting mould through a flow divider and a slag decanter by manual control, finally, cast ingots with the length and the width of 500-1000mm and the thickness of 50-70mm are obtained, and the cast ingots are demolded and cooled and then are manually crushed into the granularity of 10-60 mm. The mode has certain effects of improving the production efficiency and reducing the labor intensity. The problems that it has: firstly, high-temperature molten iron is continuously flushed to the mold wall and the mold bottom, so that the mold is seriously damaged, and the cost of the mold of a unit product is high; secondly, in the casting process, molten iron directly rushes to the die wall, the die edge and the die bottom, so that the splashing is serious, and a gap between the dies has more iron leakage, so that the yield of the molten iron is low; thirdly, the length of the belt casting machine is usually as long as 50-100m, the weight of the equipment is large, and the occupied area is large; fourthly, the alloy pulverization rate is high, and the yield is low; fifthly, casting dust and smoke are difficult to capture, and the environmental pollution is serious.

(3) Casting by a disc casting machine: the equipment for casting the copper anode plate comprises a disc, a driving system of the disc, a quantitative casting device, a spraying cooling system, a pre-jacking and jacking device, a mold locking device, an extractor, a cooling stacking device, a mold coating system and the like. The copper water flows from a copper outlet of the anode furnace to a tundish through a chute, the tundish is equivalent to a copper water storage device and alternately pours the copper water to casting ladles on two sides, the casting ladles are arranged on an electronic scale and are collectively called as a quantitative casting device, and the weight of a cast anode plate is controlled by the quantitative casting device; in the whole casting process, the disc is in the alternate of operation and stop, when the disc is static, the quantitative casting device pours molten copper into the casting mould, after casting, the disc rotates two mould positions, and the next anode plate is cast; after the anode plate is sprayed and cooled, the anode plate is loosened by pre-jacking, and in order to balance the upward acting force applied to the disc by the pre-jacking device, a mold locking mechanism is arranged above the copper mold corresponding to the pre-jacking position; taking the loosened qualified anode plate away by an extractor, and taking the unqualified anode plate away by a waste anode crane; the anode plates taken away by the extractor are placed into a water tank for cooling again and are automatically arranged into an anode stack, and finally the anode stack is transported away by a forklift. The empty copper mold is transferred to a coating station where the coating system sprays the BaS04 mixture to prevent the anode plate from "sticking". The continuous casting can be realized by continuously repeating the process. The weight of one anode plate is 250-300kg, and the rotation period of the disc is about 30 s. If the casting method and the casting equipment are applied to ferroalloy casting, massive ferroalloy is obtained, and the problem of the massive ferroalloy is basically consistent with that of a belt casting machine.
