An Experimental Rolling Mill of "Replacing Wide with Narrow" Thick Plate

Abstract

The invention discloses an experimental rolling mill for "replacing width with narrow" thick plate, which includes an ultra-fast cooling device, a roller table and a rolling mill. The rolling mill includes a frame, two pressing devices and work roll assemblies. The upper part of the frame, the work roll assembly is arranged in the frame; the work roll assembly includes the upper work roll assembly and the lower work roll assembly, the upper work roll assembly includes the upper work roll, and the two ends of the upper work roll are respectively equipped with a limited width plate and a width limit plate It is sleeved on both ends of the upper work roll and fixedly connected to the sides of the two ends of the upper work roll. The lower work roll assembly includes the lower work roll and the adjustment device arranged on the left and right sides of the lower work roll; the upper work roll assembly is fixedly connected to the pressing device. The upper work roll assembly is slidingly connected with the frame, the lower work roll assembly is arranged directly below the upper work roll assembly, and the adjustment device is fixedly connected with the frame. The rolling mill of the invention has simple structure and flexible operation, can carry out thick plate rolling in a small environment such as a laboratory, and can ensure a research effect close to that of wide and thick plate industrialized rolling experiments.

Description

technical field [0001] The invention relates to the field of metal rolling and forming, in particular to an experimental rolling mill for "replacing width with narrow" thick plate. Background technique [0002] The rolling mill is the equipment that realizes the metal rolling process, and generally refers to the equipment that completes the whole process of rolling material production. Rolling mills include large and medium-sized rolling mills for production, ordinary rolling mills and small rolling mills for laboratories. [0003] The roll diameter, roll width and rolling force of wide and thick plate rolling mills used in actual production are relatively large. Due to the large width and thickness ratio during wide and thick plate rolling, sometimes the width in the rolling process can be ignored. In the scientific and technological research of wide and thick plate rolling process Sometimes it can be simplified to a two-dimensional plane problem. However, when conducting...

AI Technical Summary

Problems solved by technology

However, when conducting experimental research on wide and thick plate rolling, the weight of the plate is too large, and the cost of industrial experiments is too high. Therefore, when conducting research on wide and thick plate rolling, sometimes the plate is reduced in proportion. Due to the original characteristics of the thick plate, the experimental process cannot accurately represent the actual rolling process
