Problems solved by technology

[0002] Metal smelting and purification have been widely used. During the smelting process, the furnace temperature can be as high as 2000°C. Since graphite is easily oxidized at high temperature, the furnace is evacuated and then filled with inert gas, but the investment in vacuuming equipment is very large. , and the sealing performance of the existing equipment is not very good
At the same time, the effect of refining the smelted metal is not very good, and it cannot make the smelted material have anisotropy and purify and remove impurities.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0021] Such as figure 1 As shown in the directional solidification melting furnace, a graphite heater 5 is arranged on the outside of the crucible. The outside of the graphite heater 5 is successively a heat-insulating reflective layer 6, a refractory layer 3 and an insulating layer 4. The effect of the heat-insulated reflective layer 6 is to dissipate heat It is reflected back to the crucible 1 to prevent the loss of heat. A thermocouple 17 is arranged on the top of the crucible 1 to measure the temperature in the crucible 1. An inert gas and a thermocouple socket 18 are arranged on both sides of the crucible 1. During the process, the furnace temperature is as high as 2000°C, and graphite is easily oxidized at high temperature, so the furnace body is filled with protective gas such a...

Description

technical field [0001] The invention relates to a smelting furnace, in particular to a water-cooled smelting furnace for melting metal and alloy ingots, purifying them and having anisotropy. Background technique [0002] Metal smelting and purification have been widely used. During the smelting process, the furnace temperature can be as high as 2000°C. Since graphite is easily oxidized at high temperature, the furnace is evacuated and then filled with inert gas, but the investment in vacuuming equipment is very large. , and the sealing performance of the existing equipment is not very good. At the same time, the effect of refining the smelted metal is not very good, nor can the smelted material have anisotropy and purification and impurity removal. Contents of the invention [0003] In order to solve the above-mentioned problems, the object of the present invention is to provide a directional solidification smelting furnace with simple structure, which can reduce the numb...
