A Melting and Electromagnetically Constrained Forming System with High Efficiency Electrothermal Conversion

Abstract

The invention discloses a melting and electromagnetic constraint shaping system capable of performing efficient electro-thermal conversion, relates to a melting and electromagnetic constraint shaping system, and aims to solve the problems of excessively large loss of a crucible, difficulty in smelting a high-titanium-niobium aluminum alloy or poor superheat degree of high-titanium-niobium aluminum alloy liquid, non-uniform electromagnetic force and poor organization control effect due to small cavity size of the conventional continuous melting and electromagnetic constraint system and unreasonable matching of a sensor and the crucible. The melting and electromagnetic constraint shaping system comprises a crucible main body, a water inlet pipe, a water outlet pipe, a thin water pipe, an induction coil and a magnetizer, wherein the crucible main body consists of an upper half body and a lower half body; each of the upper half body and the lower half body is processed from an integral copper block through linear cutting and drilling; the water inlet pipe is communicated with the lower half body through the thin water pipe; the water outlet pipe is communicated with the lower half body through the thin water pipe; the induction coil sleeves the upper half body; the magnetizer surrounds the outside of the induction coil. The melting and electromagnetic constraint shaping system is applied to the field of electro-thermal conversion.

Description

technical field [0001] The invention relates to a melting and electromagnetic constraint forming system, in particular to a high-efficiency electrothermal conversion system for forming high-melting point and high-activity metals by melting and electromagnetic constraint. Background technique [0002] The patented continuous melting and directional crystallization square cold crucible (Patent No.: ZL200710072714) solves the problem of directional solidification of titanium-aluminum alloy in the existing cold crucible, but its energy utilization rate is low, and it cannot be used for lateral heat dissipation. Thermal compensation, resulting in the discontinuity of columnar crystals. Some features of the cold crucible are that the cross section of the main body of the crucible is square, the slots are located on the four sides, and there are no diagonal slots at the four corners. Previous studies were mainly aimed at melting cold crucibles, and the optimization ideas of direct...
