Procedure for fabrication of thin cast strip by means of duo rolling cast aggregate and aggregate for implementation of this procedure

FIELD: metallurgy. SUBSTANCE: casting aggregate consists of pair of casting rollers (22) arranged horizontally and adjacent to each other forming a gap for continuous metal strip casting. A drive mechanism consists of engines (320, 330) rotating casting rollers (22) by means of driven shafts (311, 312) in opposite directions. At rotation a mechanism of control can vary angle of centring between casting rollers (22) to reduce effect of eccentricity of casting rollers on shape of strip profile. Feedback signals (371) from sensor (370) enter mechanism of control (340). The mechanism of control registers changes of strip thickness profile coming from casting rollers (22). Additional signals (351, 361) enter the mechanism of control and reflect angle positions ω 1 and ω 2 of the casting rollers. Signals (351, 361) come from sensors (350, 360) recording angular positions of driven shafts (311, 312). EFFECT: reduced deviations of cast strip thickness from required. 9 cl, 7 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 395 365 (13) C2 (51) МПК B22D 11/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21), (22) Заявка: 2008102939/02, 26.06.2006 (24) Дата начала отсчета срока действия патента: 26.06.2006 (72) Автор(ы): БЛЭЙДЕ Уолтер (US), ЭДВАРДС Джим (US) (43) Дата публикации заявки: 10.08.2009 2 3 9 5 3 6 5 (45) Опубликовано: 27.07.2010 Бюл. № 21 (56) Список документов, цитированных в отчете о поиске: US 6474406 B1, 05.11.2002.

Method and device for control over continuous cast billet solidification at continuous caster in starting casting process

FIELD: process engineering. SUBSTANCE: proposed method is implemented at continuous caster equipped with process controller. Said controller incorporates first software tool 2 to make computation in real time and to regulate casting. It incorporates second fast-computation software tool 2 to influence casting process in its starting procedure or in changing continuous cast billet parameters in current casting. Software tool 1 processes actual data of current casting process and/or data stored in data base 8 to generate correction factors. Second software tool 2 creates corrected ratings for casting using said correction factors. First software tool 2 controls casting solely with the help of said data unless casting is completely represented by data calculated in real time.
