Abstract

Inventia se refera la un echipament pentru agitarea electromagnetica în câmp progresiv a miezului lichid al semifabricatelor de dimensiuni mari obtinute prin turnare continua. Echipamentul, conform inventiei, este alcatuit dintr-un inductor liniar plan bifazat cu câmp progresiv, care se plaseaza în zona de racire secundara a liniei de turnare continua si o sursa de alimentare de joasa frecventa având frecventa si tensiunea corelate cu grosimea zonei solidificate a semifabricatului, cu distanta dintre inductor si semifabricat si cu caracteristicile otelului turnat. Antrenarea electromagnetica a miezului lichid are ca efect îmbunatatirea structurii de solidificare si a proprietatilor de utilizare a otelurilor turnate continuu.The invention relates to an equipment for electromagnetic stirring in the progressive field of the liquid core of large-scale semifinished products obtained by continuous casting. According to the invention, the equipment consists of a linear planar biphasic field inductor which is placed in the secondary cooling zone of the continuous casting line and a low frequency supply having frequency and voltage correlated with the solidified area of the blank , the distance between the inductor and the blank and the characteristics of the cast steel. The electromagnetic entrainment of the liquid core has the effect of improving the solidification structure and the use properties of the steels cast continuously.
