| description | The invention relates to a device and method for inhibiting molten steel liquid level fluctuation in a crystallizer, a stable liquid level control device is of a single-piece frame structure, a body is made of a high-melting-point and high-thermal-conductivity material, and a high-thermal-conductivity refractory material coating is sprayed on the surface of the stable liquid level control device; the overall density is 4.0-7.0 g/cm < 3 >, and the casting powder can float on the contact surface of casting powder and molten steel in a crystallizer; and the contact area between the stable liquid level control device and the upper surface of the molten steel accounts for 20-80% of the total area of the upper surface of the molten steel. On the premise that existing continuous casting process operation is not changed and normal filling of casting powder is not affected, the stable liquid level control device is adopted for effectively restraining fluctuation of the liquid level of molten steel in the crystallizer, |
