APPARATUS FOR CONTROLLING PUSH-UP OF ROLLING MILL OF A ROLLING EQUIPMENT FOR STEELWORKS AND SENSOR ASSEMBLY THEREOF

摘要

PURPOSE: A press roller elevating device of a roller for an iron mill, and an assembly sensor which is applied in the same are provided to detect the accurate displacement of a cylinder rod by preventing the twisting of the cylinder rod using a guide part. CONSTITUTION: A press roller elevating device of a roller for an iron mill comprises a pressing cylinder(100), an elevating plate(200), a sensor assembly(300), and a guide unit(400). The pressing cylinder comprises a cylinder body(110), a cylinder rod(120), and a rod cover(130). The elevation plate is ascended and descended with the cylinder rod. The sensor assembly comprises a sensor case(310), a moving body(320), and a scale rod. The scale load passes through the detection sensor within the sensor case. The guide unit prevents the twisting of the cylinder rod in ascending and descending of the cylinder rod.
