Magnetism-centered high-temperature electromagnet system

Abstract

The invention discloses a magnetism-centered high-temperature electromagnet system which is applied in the steelmaking industry. The magnetism-centered high-temperature electromagnet system comprises spiral rollers, a reference wall, a hydraulic lifting device, a pair of sizing scissors and high-temperature electromagnets, wherein the high-temperature electromagnets consist of high-temperature electromagnet coils; an attract state and a release state of a steel plate to be cut are controlled according to the condition that whether current exists in the high-temperature electromagnet coils or not; the high-temperature electromagnets are fixed at proper positions according to the thickness of the steel plate to be cut and the on-site height; when the steel plate to be cut is required to be cut, the high-temperature electromagnets are transiently excited to attract the steel plate to be cut and completely fix the steel plate to be cut. According to the magnetism-centered high-temperature electromagnet system, some key problems such as the difficulty in fixing of the steel plate and low working efficiency in a process of positioning and cutting the steel plate are solved. The system can completely fix the steel plate and accurately and quickly attract and release a material; the on-site space is saved, and remote control is easy to implement; the magnetism-centered high-temperature electromagnet system can resist high temperature and is convenient to maintain, safe and reliable.

Description

technical field [0001] The invention belongs to the field of magnetism, and in particular relates to a magnetic force pairing medium and high temperature electromagnet system, which is suitable for a steel plate cutting control system to be cut in the steel manufacturing industry. Background technique [0002] At present, most steel mills in the country use high-temperature electromagnet magnetic lifting beams to lift and transport the finished steel plates to be cut. During the hoisting and transportation of the steel plate to be cut, due to the large weight of the high-temperature electromagnet, a certain degree of impact will inevitably occur when the high-temperature electromagnet contacts the steel plate to be cut. When hoisting and transporting the steel plate to be cut in the steel plant, in the heat treatment area and the transfer area of ​​the cooling bed, because the steel plate to be cut has just come out of the furnace, the rest of the temperature is relatively h...
