Abstract
The invention discloses a partial differential pressure elimination method inside a metal vacuum smelting reduction pot and a used reduction pot.The reduction pot is provided with a metal steam channel inside; a heat conductor connected to the internal wall of the reduction pot is opened with a groove as a lead-out channel of the metal channel during the reduction reaction; the lead-out channel is directly connected with a reduction crystallizer with high vacuum degree; the reduction crystallizer is capable of sending out all the metal steam inside the reduction pot. The invention eliminates the partial damage of the partial differential pressure to the reduction reaction condition when the metal steam escapes from the existing pot during the reduction reaction, thus further realizing the elimination of the partial differential pressure and improving the smelting metal output and quality in the reduction pot.
Description
Technical field
The present invention relates to a kind of smelting equipment, the particularly a kind of method of local partial pressure in the reduction jar for vacuum metal smelting and used reduction jar eliminated.
Background technology
In the hot reducing method metal vacuum smelting is produced, through the batching suppression process produce the reduction material send into the reduction jar in carry out reduction reaction, according to the difference of reductive agent, 1000～1300 ℃ of general requirement reduction reaction temperatures, reduction jar internal pressure is less than 10Pa～13Pa.And in the reduction reaction process, can constantly have metallic vapor from material, to overflow, because being, the reduction material in the reduction jar piles up placement, be positioned at the metallic vapor that intermediary reduction material produces, because being subjected to the covering of outer reduction material can not in time send, make this local pressure be higher than 10Pa～13Pa, (347～4560Pa), the local partial pressure that the metallic vapor that the reduction material produces forms is destroyed the condition part of reduction reaction to trend towards metal vapors effusion dividing potential drop.Continue normally to carry out thereby influence reduction reaction, reduced metal output, influenced the quality of output metal.
Summary of the invention
The objective of the invention is to: a kind of method of local partial pressure in the reduction jar for vacuum metal smelting and used reduction jar eliminated is provided,, improves the output and the quality of metal smelting to eliminate the reduction jar interior local partial pressure that forms in the reduction reaction process.
Technical scheme of the present invention: eliminate the method for local partial pressure in the reduction jar for vacuum metal smelting, it is characterized in that: in the reduction jar, set up metallic vapor and derive passage, metallic vapor is overflowed along deriving passage.
In the method for local partial pressure, described derivation passage is to be made of heat conductor that is provided with diversion trench or surperficial heat conductor or other conduit that is suitable for the surface of guiding gas circulation to have through hole that has the cavity type of communicating pores in the above-mentioned elimination reduction jar for vacuum metal smelting.
The used reduction jar of local partial pressure in the elimination reduction jar for vacuum metal smelting comprises reduction jar 2, is provided with metallic vapor and derives passage in reduction jar 2; Metallic vapor is derived passage and is made of the heat conductor 1 that the surface is provided with diversion trench 4, or has the heat conductor 1 of cavity 5 to constitute by inside, or by metallic vapor delivery line 3; Be equipped with communicating pores 6 on cavity 5 and the delivery line 3.
The used reduction jar of local partial pressure in the above-mentioned elimination reduction jar for vacuum metal smelting, the diameter of the width of diversion trench 4 and communicating pores 6 are preferably less than the particle diameter of reduction material.
Compared with prior art, the present invention can effectively eliminate the reduction jar for vacuum metal smelting local partial pressure that metallic vapor is overflowed and formed when reduction reaction, guarantees that reduction reaction continues normally to carry out, and improves the output and the quality of output metal.The present invention can be used in the Metal Production by the vacuum metling thermal reduction such as MAGNESIUM METAL, strontium, zinc, beryllium.
