Problems solved by technology

However, since this method does not have the internal temperature data of molten steel, it is easy to bring large errors to the measurement. At the same time, this measurement method is not suitable for the measurement under the alternating magnetic field.
Due to the alternating magnetic field, it brings harmonic interference to the thermocouple data acquisition on the mold surface, and shielding measures must be applied

Abstract

The invention discloses a method for measuring a coefficient of heat transfer of a solidification interface under the action of an alternating magnetic field. The device comprises a thermocouple for measuring the temperature change of a metal melt and the temperature change of a cylindrical mould, an induction coil, a heat insulation material and a data collecting and calculating system. Through measuring the temperature change of the metal melt and the mould under the action of the alternating magnetic field generated by the induction coil and using a reverse heat transfer calculation program, the coefficient of the heat transfer of the solidification interface in the metal solidification process is obtained. The device is capable of measuring the coefficient of heat transfer of the metal interface under the action of the alternating magnetic field, and provides a basis for applying the electromagnetic field in the solidification process.

Description

technical field [0001] The invention belongs to the technical field of metal solidification heat transfer measurement, and in particular relates to a device for measuring interface heat transfer coefficient in a metal solidification process under the action of an alternating magnetic field. technical background [0002] In the metal casting process, due to the good thermal conductivity of the metal material, the heat transfer resistance between the casting and the mold is mainly concentrated on the interface between the two, and the control of the interface heat transfer coefficient during the solidification process often becomes the controlling factor of the solidification heat transfer , has a great influence on the solidification process of castings. Since there are many factors affecting the interfacial heat transfer coefficient, such as interface contact conditions, physical conditions, chemical conditions, and interface temperature, the interfacial heat transfer coeffi...
