摘要： THE OPERATION OF DRIVERS FOR THE ROLLS OF A ROW OF ROLLS STANDS IN A ROLLING MILL FOR TREATMENT OF HOLLOW BLOOMS WHICH ARE MOUNTED ON MANDRELS AND ARE CONVERTED INTO TUBULAR ARTICLES DURING A PASS THROUGH THE MILL IS REGULATED IN SUCH A WAY THAT THE SPEED OF THOSE ROLLS WHICH ENGAGE THE BLOOM IS REDUCED WHEN THE LEADING END OF THE BLOOM REACHES THE ROLLS OF THE SECOND STAND AND, WHERE APPROPRIATE, AGAIN WHEN THE LEADING END OF THE BLOOM REACHES THE ROLLS OF ONE OR MORE NEXT-FOLLOWING STANDS, AND WHEN THE TRAILING END OF THE BLOOM LEAVES THE ROLLS OF THE FIRST STAND AND, WHERE APPROPRIATE, AGAIN WHEN THE TRAILING END OF THE BLOOM LEAVES THE ROLLS OF ONE OR MORE NEXT-FOLLOWING STANDS. THE REDUCTION IN THE SPEED ROLLS IS A FRACTION OF THE DIFFERENCE BETWEEN THE SPEED OF THE MANDREL PRIOR AND SUBSEQUENT TO ENTRY OF THE LEADING END OF THE BLOOM INTO A PARTICULAR STAND OR A FRACTION OF THE DIFFERENCE BETWEEN THE SPEED OF THE MANDREL PRIOR AND SUBSEQUENT TO ISSUE OF THE TRAILING END OF THE BLOOM OUT OF A PARTICULAR STAND.
摘要翻译： 管坯在支撑在心轴上的同时在连续研磨机中还原，心轴在轧制过程中向前进给。 当整个坯料已经减少时，心轴的上游端保持静止，并且轧辊由辊7从心轴剥离。 然后使用驱动辊6将该心轴从磨机中取出。

摘要： A method for rolling down tubular material in a rolling mill wherein in the vicinity of the starting sections and/or end sections of the tubular material normally having thickened portions a stepwise variation of the rotational speeds is provided at the roll stands deforming these sections, said stepwise variation of said rotational speeds required for rolling the central section of the tubular material.
