Embodiment 1
[0069] The equipment used in this example is figure 1 shown.
[0070] In this embodiment, the steps of the continuous casting funnel mold molten steel solidification and slab simulation method are as follows:
[0071] 1) Put a 50Kg experimental steel block with a size of 50×50×50mm into the induction steelmaking furnace, and in the case of argon protection, start the induction heating to heat the molten steel to 1500°C and keep it for 20 minutes until it is completely melted into steel liquid.
[0072] 2) Add 100g of mold slag particles to the surface of the molten steel. The high-temperature molten steel will melt the mold slag particles into a liquid state and cover the surface of the molten steel to absorb the floating inclusions on the surface of the molten steel. After 5 minutes, the surface of the molten steel will absorb the inclusions. Remove the protection residue.
[0073] 3) Add 200g of mold slag particles to the molten steel again, and after standing for 10 min...

Abstract
The invention discloses a continuous casting funnel-shaped crystallizer molten steel solidification and casting blank simulation device and a using method thereof. The simulation device comprises a steelmaking furnace, a motor driving system, a continuous casting funnel-shaped crystallizer simulation system, a cooling water system and a temperature acquisition system. Accoridng to the device, by simulating a solidification process and a continuous casting process of molten steel in a funnel-shaped crystallizer in thin slab continuous casting production, an initial solidification slab shell with actual thin slab characteristics and a temperature change curve in the crystallizer are obtained, the simulation study on an initial solidification behavior of the molten steel in the funnel-shapedcrystallizer, and influence of the surface quality of a casting blank and continuous casting process parameters on the initial solidification behavior of the molten steel is realized. The device is suitable for simulating production of existing steel types and can also be used for development and research of thin slab continuous casting production of crack-sensitive steel types. Compared with an actual continuous casting industrial production process of a thin slab, the device has the advantages of simplicity and convenience in operation, low experimental cost and the like.
Description
technical field [0001] The invention discloses a continuous casting funnel-shaped crystallizer molten steel solidification and billet simulation device and a use method thereof, which belong to the technical field of iron and steel metallurgy. Background technique [0002] In the 1990s, after two oil crises and three financial crises, the global economy was sluggish. As an industry with high energy consumption and low profits, the iron and steel industry must face structural adjustment, technological optimization, and process improvement to enhance competitiveness and Guaranteed economic benefits. Therefore, the short-process process represented by thin slab continuous casting and rolling has received special attention from investors and manufacturers because of its low energy consumption, low cost and high efficiency. Since the first thin slab continuous casting and rolling production line-CSP process line developed by German SMS Siemag was completed and put into operation...
