Abstract
"APARELHO E PROCESSO PAPA FABRICAçãO DE UMACHAPA DE AçO LAMINADA A QUENTE, PROCESSO EAPARELHO PARA PRENSAGEM DE ESPESSURA DE CHAPA EPROCESSO PARA FORMAçãO DE PLACA". De acordo com umaparelho e um processo para fabricação de uma chapa de açolaminada a quente, um processo de desbaste para reduzir umaespessura de uma placa continuamente lingotada é executadopara obter uma barra de chapa, e um processo de laminação deacabamento para laminar a barra de chapa é efetuado paraproduzir uma chapa de aço laminada a quente tendo umaespessura de chapa predeterminada. Depois de esfriamento, achapa de aço laminada a quente é então laminada. Um par dematrizes 6 cada uma das quais têm uma parte afilada 6b em umlado de entrada e uma parte paralela 6b em um lado de saída sãousadas em pelo menos parte do processo de desbaste. Ademais,antes de executar prensagem de espessura de chapa a ummaterial em uma direção de espessura de chapa usando asmatrizes 6, pelo menos uma de uma extremidade dianteira e umaextremidade traseira do material é prensada em uma direção nosentido de largura para ser pré-formada."APPLIANCE AND PAPA PROCESS MANUFACTURING A HOT-LAMINATED STEEL UMACHAPA, PROCESS AND APPLIANCE FOR PRESSING PLATE THICKNESS AND PROCESSING FOR PLATE FORMING". According to a device and a process for making a hot rolled steel plate, a roughing process to reduce a thickness of a continuously cast plate is performed to obtain a plate bar, and a finishing lamination process to laminate the plate bar is made to produce a hot rolled steel sheet having a predetermined sheet thickness. After cooling, the hot rolled steel slab is then rolled. A pair of matrices 6 each of which have a tapered part 6b on an input side and a parallel part 6b on an output side are used in at least part of the roughing process. In addition, before performing plate thickness pressing on a material in a direction of plate thickness using asymmetries 6, at least one of the front end and one rear end of the material is pressed in a direction in the width to be preformed.
