Description
Technical field
The utility model is related to vacuum metallurgy equipment technical field, specially one kind is placed in horizontal positioned magnesium vacuum reduction tank
Interior material boat prepares magnesium, lithium, the equipment of the high-vapor-pressure metals such as strontium, calcium available for thermal reduction.
Background technology
Magnesium, lithium, the high-vapor-pressure metals such as strontium, calcium can under vacuum be prepared using thermal reduction.Industry refining magnesium
Main method has electrolysis and thermal reduction.Smelting magnesium by thermal reduction process technology based on ferrosilicon process (i.e. Pidgeon process) is more perfect,
It is widely used for domestic most lifes.At present, it in China overwhelming majority magnesium smelting reduction pot without heat source, is come under vacuum state
External heat is successively transmitted from outside to inside with forms of radiation, and reductive jar central axis temperature is minimum, and pelletizing material is heated most slowly,
This temperature uneven phenomenon seriously restricts the raising of rate of reduction.Therefore, new technique and technology are studied, strengthens in tank and passes
Heat improves energy utilization rate, shortens reduction cycle, has higher research and application value.
Magnesium-smelting silicothermic process uses horizontal tank reduction furnace mostly：This reduction furnace is the structure of cylinder tank, due to its long-term work
Under 1200 DEG C of temperature, an extraneous atmospheric pressure, tank body is very long in addition, is just inevitably acted on by external force.This
Kind of high temperature, high pressure, external force integrated condition, reductive jar can deform in a short period of time so that the reductive jar lost of life.It is this
In addition to state increases energy consumption when because tank skin slagging, due also to its tank skin deformation and leading to not carries out mechanical Cosmetic material, discharging, clearly
The implementation and operation of a series of mechanization measures such as slag drastically influence the development process of refining magnesium industry.
Heat-transfer device is installed additional in reductive jar for the slow problem of heat conduction of material in reductive jar, Su Ming etc., so as to enhance
Heat transfer in tank makes the recovery time shorten to 4~5h, but heat-transfer device is chronically in hot environment, easily causes deformation,
Service life is shorter.Feng Jun little is using material in reductive jar as research object, influence of the analysis material distribution mode to heating time, and right
The diabatic process of material carries out numerical simulation, proposes a kind of novel refining magnesium material block.The material block can improve the heat transfer type of material, contracting
Short heating time improves production efficiency.The problems such as magnesium vacuum reduction tank overcomes yielding previous reductive jar, short life.Due to
Previous process for smelting magnesium so that reductive jar is yielding and leads to not carry out a series of mechanizations such as mechanical Cosmetic material, discharging, scarfing cinder
The implementation and operation of measure.Tinkling of pieces of jade etc. is appointed to be proposed for the present situation for manually taking on material in current metal magnesiothermic reduction process using nothing
Machinery dress discharge method of the axis conveyor screw as Guan Nei executing agencies.Dress discharging time can be shorten to 15min by 2h, contracted significantly
The time of short thermal reduction process.
Problem of the existing technology is：Without heat source in China's overwhelming majority magnesium smelting reduction pot, come under vacuum state
External heat is successively transmitted from outside to inside with forms of radiation, and reductive jar central axis spot temperature is minimum, and pelletizing material is heated
Most slow, this temperature uneven phenomenon seriously restricts the raising of rate of reduction；Previous process for smelting magnesium cause reductive jar yielding and
Lead to not carry out the implementation and operation of a series of mechanization measures such as mechanical Cosmetic material, discharging, scarfing cinder, extend reduction process
Time.
