Embodiment Construction
[0028] The specific implementation of the method for slab continuous casting mold breakout prediction based on casting resistance is divided into the following steps:
[0029] IData collection
[0030] Data collection is completed by the selected hydraulic crystallizer vibration device and power meter.
[0031] i) Due to the extremely harsh environment of the billet shell, the interior is hot molten steel, the exterior is mold slag (or liquid or solid or molten state) and water-cooled mold copper plate, making it difficult to directly measure the casting resistance. So use the indirect method of measurement:
[0032] F = 9.545 × ΔP × η f × r
[0033] In the formula, F-drawing resistance (KN); ΔP-vibration motor power difference between drawing and empty vibration (KW); η-mechanical transmis...
