Embodiment Construction

[0033] According to the background technology, the quality of the ingot produced by smelting in the prior art needs to be further improved.

[0034] The crystal grains of the ingot produced by smelting in the prior art are relatively coarse, so that the strength, hardness, toughness and plasticity of the ingot need to be further improved.

[0035] After analysis, metals are usually polycrystals composed of many crystal grains. The grain size can be characterized by the number of crystal grains per unit volume. In a certain volume of crystals, the more grains there are, the finer the metal grains will be. Generally speaking, the finer the grain of the metal part, the better the plasticity and toughness of the metal.

[0036] The method of improving the mechanical properties of metal materials by refining grains is called fine grain strengthening. Generally, the fine-grain strengthening method of an ingot is that after the ingot is produced by smelting, the ingot is subjected t...

Abstract

The invention relates to smelting equipment and a smelting method. Specifically, the smelting equipment includes: a crystallizer; an ingot pulling mechanism, which is connected to the bottom of the crystallizer; a vibrating mechanism, which is suitable for vibration of the ingot pulling mechanism. The equipment and method provided by the invention simplify the metal grain refinement process whilereducing the grain size of the ingot, make the later TMP (plastic deformation and recrystallization process) operation simple, and also reduce the heat treatment procedure and equipment investment, thereby substantially lowering the production cost.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a smelting equipment and a smelting method. Background technique [0002] Electron Beam Refine Furnace (EB furnace) is a vacuum melting equipment that uses the kinetic energy of high-speed moving electrons to convert heat energy as a heat source to melt metals into ingots. Due to the high vacuum degree and good purification effect of the EB furnace, it can simultaneously remove non-metallic element impurities and low-melting-point metal impurities in metals, so it is widely used in the production of clean metals and plays an important role in the production of high-purity refractory metals and refractory metal alloys. important role. [0003] The electron beam melting furnace bombards high-temperature refractory metals with high-speed electron beams emitted by one or more electron gun cathodes under relatively high vacuum conditions, and the kinetic energy of the electron...
