Abstract

FURADEIRA DE PE RCUSSãO. Trata-se de um instrumento para limpeza da barra de mandril capaz de suprimir eficientemente a carburização gerada na superfície interna de um tubo ou cano, sendo que o tubo ou cano é alongado e laminado sem interferir na operação. Um instrumento para a limpeza da barra de mandril 15, de acordo com a presente invenção, limpa uma barra de mandril B retirada de uma linha de transporte da barra de mandril após ter sido usada para alongar e laminar um tubo ou cano em uma usina de mandril 8. O instrumento para a limpeza da barra de mandril 15 é dotado de dispositivos de transporte 17 e 18 que transportam a barra de mandril B na direção axial à medida que rotacionam a mesma na direção periférica, dotado de dispositivos de limpeza ld que são dispostos de maneira oposta ao lado da barra de mandril B transportada pelos dispositivos de transporte 17 e 18 e dotado de água de alta pressão que possui uma pressão de água de 0,2 a 150 MPa (preferencialmente, 20 a 150 MPa) em direção à superfície externa da barra de mandril B.
