Through intermediate control production, molten iron is discharged into a ladle at regular time through a furnace mouth, solution is used as a cooling mould through a crown block crane and an ingot mould, finally a solid alloy product is formed, and molten iron casting is the most commonly used method for changing liquid iron alloy into solid alloy.

Meanwhile, in the ingot mold casting process, crown block iron clamping is needed, more labor is needed in front of the furnace, the labor intensity of workers is high, the operation environment is poor, and potential safety hazards in the operation process are high.
2. Pool casting is a pit casting method in which casting of iron alloy is completed in a pit of a special construction. The bottom and side walls of the pit are pre-paved with a solid alloy of similar composition to the alloy being cast, then the liquid alloy is poured into the pit, and the pit is covered as much as possible, so that a thin layer is formed, and the molten iron is quickly solidified. After cooling for a certain time, the solidified ferroalloy may be re-poured with a liquid alloy. Casting for many times to ensure that the thickness of the whole alloy reaches 1200-1800 mm and the whole pit is filled. When the pit casting method is adopted, at least two pits are arranged in the casting field and are used in turn. One pit is used for casting, and the other pit is used for taking iron and preparing for casting. The pit casting method is characterized by high labor productivity, no consumption of ingot mould, low production cost, but poor labor condition.
3. The casting machine is used for casting, and through finishing all procedures of the whole casting process of mould preparation, alloy injection, demoulding and the like in the casting machine, the labor intensity of workers can be effectively reduced, but the automation degree and the production efficiency of the casting machine are also various.

Specifically, referring to fig. 2-4, in operation of the twin-wire continuous casting system, an empty ingot mold is first placed on the first and second rails 16, 26 of the first and second casting platforms 1, 2, respectively. By starting the first pushing device 11 of the first casting platform 1, the first ingot module 10 corresponding to the first casting platform 1 is slowly moved. Simultaneously, the second propelling device 21 of the second casting platform 2 is started, so that the second ingot module 20 corresponding to the second casting platform 2 slowly moves. The first transfer stage 3 is started, and the ingot module moved to the end of the second casting stage 2 is transferred to the starting end of the first casting stage 1 by the first transfer stage 3. The second transfer platform 4 is started, and the ingot module moving to the tail end of the first casting platform 1 is transferred to the starting end of the second casting platform 2 through the second transfer platform 4. The fixed point casting of molten iron is performed at this time by fixing the first ladle 12 and the second ladle 22. The first ingot mould set 10 after casting molten iron generates a product, the product is moved to the first crushing device 15, the product mould iron is crushed to be separated from the first ingot mould set 10, meanwhile, the first mould turning device 14 is utilized to change the movement track of the product, demoulding is instantaneously completed, the demoulded first ingot mould set 10 is transported to the second casting platform 2 through the second transporting platform 4, the second mould gap device 23 and the second mould coating spraying device 27 are sequentially used for completing iron powder spraying and coating, and the subsequent procedures are sequentially completed through the second molten iron ladle 22, the second crushing device 25 and the second mould turning device 24. That is, the first ingot mould set 10 in the first casting platform 1 is firstly processed in the first casting platform 1, transferred by the second transfer platform 4, and then processed in the second casting platform 2. Similarly, the second ingot mould set 20 is processed on the second casting platform 2, transferred by the first transfer platform 3, and then processed on the first casting platform 1.
The structure of the two-wire continuous casting system can be described with reference to the text related to fig. 2 to 4 in the above embodiments, and will not be described herein again.
The embodiment of the invention provides a method for controlling a double-line continuous casting system, which is characterized in that the starting end of a first casting platform 1 is connected with the tail end of a second casting platform 2 through a first transfer platform 3, and meanwhile, the tail end of the first casting platform 1 is connected with the starting end of the second casting platform 2 through a second transfer platform 4, so that the first casting platform 1 and the second casting platform 2 are matched with the first transfer platform 3 and the second transfer platform 4 to form an annular production line, on one hand, smoke dust generated in the casting process is more easily collected by using the double-line continuous casting system to meet the environmental protection requirement, on the other hand, the double-line continuous casting system can replace the casting system in the current ferrosilicon and industrial silicon industry, the economic benefit is improved, the labor intensity of workers is reduced, the mechanical automation level of casting is improved, and the problems of smoke emission, high labor intensity, high potential safety hazard, poor working environment, low mechanical automation degree and the like in the casting process are effectively solved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
