Electron beam melting furnace
Under high vacuum, high-speed electron beam kinetic energy is converted to heat as a heat source for metal smelting a vacuum melting method.
Electron beam melting furnace equipment
A typical electron beam melting furnace generally consists of 6 parts:
(1) electron gun. Electron gun is the heart of electron beam melting furnace. It includes a gun head (usually by the filament, cathode, anode, etc.), focusing coil and deflection coil. According to its structure, electron guns can be divided into axial guns (also known as Pierce guns), non-self-accelerating annular guns, self-accelerating annular guns and transverse guns. Their basic structures and their operation during electron beam melting are shown in Fig. 2. The number of electron guns single gun, double guns and more guns.
(2) feed system. If the raw materials for the prefabricated consumable electrode, the general use of vertical or horizontal mechanical feeding: If the raw material for the crumbs, blocks or granular, then the way to the silo.
(3) ingot system. Including mold, pull ingot institutions and institutions out of the bar.
(4) vacuum system. Including vacuum units, vacuum chamber, vacuum piping and valves and vacuum measurement system.
(5) power system. Including the main power (gun power) and control power and operating power.
(6) cooling system. Including all cooling water and pipeline valves.
Melting power of electron beam melting furnace
Ingots in the melting of the required electron beam production, the commonly used graphical method for electron beam melting power. From Figure 4 can be referred to as the melting power ~ (kW) or melting power, which with the melting of gold to see, the melting power and material; the same material, with the ingot directly under the species, crucible diameter and melting speed, the general The square of the diameter can be proportional to the following formula; and when the same power, then the natural diameter of the ingot: logarithm and metal material is inversely proportional to the melting point.
