Description

Technical Field

[0001] The utility model relates to the technical field of mica plates, in particular to a mica heating plate for a multi-layer high-temperature furnace. Background Art

[0002] Mica heating plate uses the good insulation performance and high temperature resistance of mica board (mica sheet). It uses mica board (sheet) as the skeleton and insulation layer, supplemented by galvanized sheet or stainless steel plate for support and protection. It can be made into various shapes of heating devices such as plate, sheet, cylinder, cone, tube, circle, etc. The designable power is up to 1000W and the temperature resistance is 600℃. The existing mica heater generally winds the heating wire evenly on the mica board, and uses the mica board as support and insulator. The disadvantage is that the volume of the whole heater is relatively large, requiring a large installation space, and the heating wire and mica board adopt a fixed structure. When the heating wire fails and breaks, it can only be replaced as a whole and cannot be repaired, which is costly.

[0004] In practical applications, the above technical solution has the problem that the heating wire and the mica board are integrated and difficult to repair.

[0005] Therefore, it is necessary to invent a multi-layer high-temperature furnace mica heating plate to solve the above problems. Utility Model Content
