发明名称 CONTROL METHOD FOR PLATE WIDTH IN HOT STRIP MILL
摘要 <p>PURPOSE:To control the width of a hot strip with high accuracy by adjusting the plate width adjusting quantity of a finishing rolling mill with the subtraction of the winding front face target width and the winding tension varying width from the finishing front face plate width in the rough rolling mill group and finishing rolling mill group consisting of vertical and horizontal rolls. CONSTITUTION:The hot strip having passed the vertical rolling mill 1 consisting of a vertical roll and horizontal roll and a rough rolling mill group 2 is wound to a winder 7 through a finishing rolling mill group 3. the value WR of the roughened face width measuring instrument 4 of the front face of the finishing rolling mill group 3, the value WCA of a winding front face width measuring instrument 6 and the value of the finished face width measuring instrument 5 are found. The width of the finishing rolling mill group 3 is adjusted by the adjusting width DELTAWCA of the winding front face width measuring instrument 6. The plate width of the hot strip is controlled with high accuracy because of the plate width variation by the tension of the winder 7 being added to.</p>
