连铸机主要设计参数的确定(国外英文资料) The determination of the main design parameters of the continuous casting machine (6) the flow of a continuous casting machine A continuous casting machine can cast the total number of castings at the same time as the number of streams for a continuous casting machine. One machine has only one unit, which can only be cast and cast in the first class. If two or more castings can be cast, it is called a multi-stream. In the case of a continuous casting machine, multiple units are cast and cast separately, which is called multi-machine multi-flow. A multi-flow machine multi-flow equipment weighs light, investment province. But it is difficult to make the whole machine stop and the production operation and the flow is difficult. Under the condition of certain operation technology level, when casting billet section size was determined, by throwing speed and ladle allows pouring time limit, if increase the production capacity of continuous casting machine, you must increase the number of flow continuous casting machine, in order to shorten the casting time. In recent years, the small square billet casting machine has cast up to 12 streams at most, most of them with one to four streams, and the large slab has the maximum cast of four streams, often one to two streams. If the capacity of the ladle is G (t), of each flow casting off area of S (m2), when the casting speed v (m/min), a continuous caster must flow number n, can press type calculation: N is equal to 7 minus 17. Type: G - steel capacity (t); T - the amount of time that the ladle allows, min; S -- the area of the cast billet, m2; V - pull speed, m/min; Rho - cast billet density (t/m3), carbon calmness steel rho = 7.6, the boiling steel rho = 6.8. The flow number of a continuous casting machine depends mainly on the capacity of the ladle, the process of smelting, the casting and casting machine, and the speed of the casting. Calculation of the production capacity of the continuous casting mach
