Electromagnetic suspension type solar heat treatment furnace

Abstract

The invention discloses an electromagnetic suspension type solar heat treatment furnace comprising a furnace body, a solar automatic tracking and heating system, a solar photovoltaic power supply system, an electromagnetic suspension system and a temperature control system. A to-be-processed workpiece is arranged in the furnace body; and the focal point formed by the solar automatic tracking and heating system is located on the to-be-processed workpiece. The solar photovoltaic power supply system receives sunlight and transforms the sunlight into the electric energy and is used for providing power for the solar automatic tracking and heating system, the electromagnetic suspension system, and the temperature control system. The electromagnetic suspension system generates a multi-dimensionalmagnetic force to control the to-be-processed workpiece to be suspended and rotate. According to the invention, the to-be-processed workpiece is heated by using the sunlight directly and is controlled to be suspended and rotate by using the multi-dimensional magnetic force generated by the electromagnetic suspension system, so that the to-be-processed workpiece is heated by the focal point of a Fresnel lens uniformly. Therefore, the uniformity of heating of the to-be-processed workpiece is ensured and a phenomenon that the to-be-processed workpiece is damaged due to the too high local temperature is avoided.

Description

technical field [0001] The invention belongs to the field of heat treatment equipment, and relates to a heat treatment furnace, in particular to an electromagnetic levitation solar heat treatment furnace. Background technique [0002] When heat-treating workpieces, current heat-treatment techniques usually use electrical energy for heating. Due to the need for high temperature and long-time heating for the work, a large amount of electric energy is consumed, and the cost of electric power consumption and heat treatment is high. Now solar energy is used to melt materials for casting, or melt working fluid for heat conduction and energy storage, or use concave mirrors for daily cooking. However, since the workpiece is heated by focusing the solar energy, the energy density at the focus of the solar energy is extremely high, and the heat is too concentrated, which will cause the local temperature of the workpiece to be too high and damage the workpiece.
