High-frequency electromagnetic induction straight hot press heating plate

Abstract

The invention discloses a high-frequency electromagnetic induction straight hot press heating plate. The high-frequency electromagnetic induction straight hot press heating plate comprises a steel plate and a high-temperature electromagnetic wire; a row of wire holes penetrating through the steel plate are formed in the positions, parallel to the upper surface and the lower surface, of the middleof the steel plate and are distributed at equal intervals, and the distance between centers of every two adjacent wire holes is 5-10 cm; when the distance between centers of every two adjacent wire holes is 5-8 cm, the high-temperature electromagnetic wire is threaded through the wire hole according to the principle that the current direction of every two adjacent holes is consistent as much as possible, and the two ends of the high-temperature electromagnetic wire are connected with a high-frequency heating power source and a controller. According to the high-frequency electromagnetic induction straight hot press heating plate, through the wire hole forming mode, the self structure of the steel plate is not changed as much as possible, and it is ensured that the mechanical property of thesteel plate is not changed; and meanwhile, it can be ensured that electromagnetic energy is absorbed by the steel plate sufficiently and converted into heat energy, the whole steel plate is uniform in heating, and an existing flat hot pressing plate is transformed advantageously.

Description

technical field [0001] The invention relates to the field of press equipment, in particular to an environmental-friendly, high-efficiency, energy-saving high-frequency electromagnetic induction direct heat press heating plate. Background technique [0002] At present, the production of wood-based panels (furniture) generally requires the use of hot presses. At present, the heat source of the hot press comes from the external heat source of the press, such as (coal, oil, gas, etc.) The heat energy is transferred to the hot pressing plate of the hot press for hot pressing and lamination of the plates (furniture). It is well known that the energy transfer process is accompanied by energy loss, and at the same time, due to the influence of heat exchange efficiency, the thermal efficiency is reduced, making the energy efficiency very low, so there is a huge waste in energy saving and economy. As more and more attention is paid to environmental protection issues, high-pollution e...

Problems solved by technology

However, the existing high-frequency heating methods all have the defect of destroying the mechanical structure of the hot-pressed steel plate. Due to the large size of the steel plate, the existing way of setting wire grooves has changed its original mechanical structure, which can easily cause it to sag due to gravity and withstand pressure shocks. while deformed
