Embodiment Construction

[0018] Embodiment: the existing reduction tank is a tubular hollow structure, as shown in Figure 7, the temperature of the reduction material 4 in contact with the tank body 2 in the reduction tank rises rapidly, and the reduction material 5 that cannot be in contact with the tank body 2 can only pass through The reducing materials in contact with it transfer heat and radiate heat to increase the temperature to reach the reaction temperature to realize the reduction reaction. The temperature of these reducing materials relying on indirect heat conduction rises slowly, and it takes a long time to reach the reaction temperature. The method of the present invention is to add a heat conductor 1 connected to the tank body 2 in the reduction tank, increase the heat conduction area inside the reduction tank and reduce the heat conduction distance between the heat conductor 1 and the reduced material, thus increasing the contact area between the reduced material and the heat source , a...

Abstract

The invention discloses a material heating speed increase method in a metal vacuum smelting reduction pot and a reduction pot. The invention is provided with a heat conductor connected with the pot body inside the metal vacuum smelting reduction pot to increase the heat conduction area and decrease the distance between the heat conductor and the reduction material and therefore the heating speed of the reduction material is enhanced. Under the condition of having no effect to the reduction reaction, the heat conductor shape and setting mode are arbitrary. By adding the heat conductor inside the reduction pot, the invention is not only capable of shortening the heating time consumption during the reduction reaction, improving the production efficiency of unit time, decreasing the energy consumption and production cost, but also capable of enhancing the strength of the reduction pot and prolonging the service life. The invention can be applied in the metal production of the magnesium, strontium, zinc, beryllium, etc. through the vacuum smelting heat reduction.

Description

technical field [0001] The invention relates to a method and device for metal vacuum smelting, in particular to a method and device for rapid reduction of metal vacuum smelting in a reduction tank. Background technique [0002] In the production of metal vacuum smelting reduction method, the reduced material produced through the batching and pressing process is sent to the reduction tank for reduction reaction. According to the difference of the reducing agent, the reduction reaction temperature is generally required to be between 1000 and 1300 °C, and it can be heated by fuel or electricity. The reduction tank makes the reduction material reach the required temperature value to realize the reduction reaction. The existing reducing tank has a tubular structure. When the reducing material is loaded into the reducing tank for heating, the heat conduction is transferred to the reducing material through the tank wall of the reducing tank, and the material that cannot be in conta...
