Embodiment 1

[0019] Embodiment 1: according to the magnetic steel volume and outline mechanic, the mold of the magnetic steel heat-insulating protective cover is placed on the outer layer of the abrasive tool with an asbestos cover, and the three materials of resin, talcum powder and chopped yarn are mixed in a certain ratio (3: 2 : 1) Evenly apply 3-5mm on the surface of asbestos, dry naturally or in an oven, and finally evenly coat 1-2mm of aviation heat insulating paint on the outermost layer. When in use, use the magnetic steel heat insulation cover to cover the magnetic steel, and use the fixing bolts and fixing accessories to install the magnetic steel heat insulation cover with the magnetic steel on the inner side of the rail specified in the iron ladle tracking system. The communication cable of the pipe passes under the rail to connect with the communication equipment in the side box.

Embodiment 2

[0020] Embodiment 2: As a modified example of the magnetic steel heat shield of the embodiment, the mold of the heat shield can be processed according to the volume and contour of the communication product antenna in the iron bag tracking system, and the antenna magnetic steel heat shield can be produced. When in use, put the antenna heat shield from one end of the antenna and push it to the other end of the antenna, cover the antenna completely, and fix the antenna on the rail sleeper with bolts through the antenna fixing frame and fixing accessories, and fix the bolts at the same time Play the role of fixing the antenna and its antenna heat shield.

Abstract

The invention relates to a magnetic steel heat-insulating shield and a manufacturing method thereof, belonging to the technical field of magnetic steel protection. The shield comprises an upper shield (1) and a mounting bottom plate (2), wherein the mounting bottom plate (2) is provided with two mounting holes (3), and the upper shield (1) comprises three heat-insulating layers including an aviatic heat-insulating dope layer (4), a glass reinforced plastic heat-insulating layer (5) and an asbestos heat-insulating layer (6). In the manufacturing method, a mold for the magnetic steel heat-insulating shield is manufactured according to the volume and the contour of magnetic steel, asbestos casing is packed at the outer layer of the mold, and resin, talcum powder and spun yarn which are mixedby the ratio of 3:2:1 are evenly coated to the surface of the asbestos for 3-5mm, and are naturally dried or died by an oven; and finally, the aviatic heat-insulating dope is evenly coated at the outermost layer for 1-2 mm. The invention has the advantage that the working temperature of the magnetic steel is controlled to be below 65 DEG C, and completely reaches the working temperature required by the magnetic steel, thereby the microwave radio-frequency recognition technology can be used in an iron cased following system of a steel company.

Description

technical field [0001] The invention belongs to the technical field of magnetic steel protection, and in particular relates to a magnetic steel heat-insulating protective cover and a manufacturing method thereof, which can prevent communication products from being affected by external temperature during operation. Background technique [0002] The application of microwave radio frequency identification technology to realize logistics management on railway transportation lines has been mature, but in iron and steel enterprises, the application of this technology is limited because communication products are affected by the temperature of iron ladle. The reason is that the communication products (magnetic steel and antenna) tracked by the iron ladle need to be installed on the track and the sleeper respectively. Since the surface temperature of the ladle reaches above 130 degrees Celsius, the magnetic steel and antenna (the upper limit of the working temperature) installed on t...
