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 mixed by 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
The invention belongs to magnet steel guard technology field, particularly relate to a kind of magnetic steel heat-insulating shield and manufacture method thereof, be not subjected to the heat-insulating shield of extraneous thermal effect when making communication products work.
Background technology
Adopt the microwave radio recognition technology, realize that the application of logistics management on railway supplyline is ripe, but in iron and steel enterprise,, make this The Application of Technology be restricted because communication products are subjected to iron bag Temperature Influence.Reason is that the communication products (magnet steel and antenna) of iron packet tracing need to be installed on track and the sleeper respectively, because the surface temperature of ladle reaches more than 130 degrees centigrade, cause the magnet steel that is installed on track and the sleeper and antenna (70 degrees centigrade of the working temperature upper limits) at the iron bag through out-of-date because of being subjected to Temperature Influence cisco unity malfunction even damage.
Summary of the invention
The object of the present invention is to provide a kind of magnetic steel heat-insulating shield and manufacture method thereof, solved the working environment problem of magnet steel, make magnet steel under its protection, not be subjected to Temperature Influence and work that can normal reliable.And then the reliable application of realization microwave radio recognition technology in iron packet tracing system of iron and steel enterprise.
Originally give out a contract for a project and draw together cover (or antenna heat-insulating shield), installation base plate, base plate is processed with 2 rectangle mounting holes, and the adjusting when conveniently magnet steel being installed is with fixing.
The cover of going up of the present invention is made up of three thermofins, comprises aviation insulating moulding coating layer, frp layer, asbestos layer.
Of the present invention to go up the cover innermost layer be asbestos, because it is soft relatively, its processing in the innermost layer, in heat insulation, bumped the mill of magnet steel and played buffer action through out-of-date vibrations and middle layer housing to magnet steel the iron hired car.
Upward cover of the present invention middle layer is a fiberglass, and the one-tenth of fiberglass is grouped into has selected resin+talcum powder+weak point yarn cutting, makes it when finishing heat-blocking action, also plays effect fire-retardant and increase heat-insulating shield intensity.
Upward cover outermost layer of the present invention is the aviation insulating moulding coating: be used for further strengthening effect of heat insulation, the heat reflectivity of this material heat is 0.85, and the continuous firing temperature is-51 ℃-206 ℃.
The manufacture method of heat-insulating shield of the present invention is: the mould for preparing magnetic steel heat-insulating shield by magnet steel volume and profile, asbestos cover on the outer pad of mould, resin, talcum powder, three kinds of materials of short yarn cutting are mixed in (3: 2: 1) ratio, evenly be applied to asbestos surface 3-5mm, nature or baking box oven dry are evenly coated aviation insulating moulding coating 1-2mm at outermost layer at last.
Effect of the present invention: after using heat-insulating shield of the present invention that the magnet steel that is installed in the track inboard is carried out heat insulation protection, the working temperature of magnet steel is controlled in below 65 degrees centigrade, reached the desired working temperature of magnet steel fully, made the microwave radio recognition technology in iron packet tracing system of iron and steel enterprise, obtain to use.
