Abstract
The utility model discloses a high-temperature electric forge comprising a forge body. The forge body comprises a heat processing section, and the heat processing section sequentially comprises a forge shell, a carbon black heat-insulating layer and a carbon brick lining layer from outside to inside. The carbon black heat-insulating layer and the carbon brick lining layer are adopted, so that defects that high-alumina bricks cannot bear high temperature over 1400 DEG C and the lining is burned out are overcome, delivery rate of power can reach 2000-2500 KWH, temperature of a position close to carbon bricks can reach and exceed 2000 DEG C, carbon particle raw materials in the forge can be evenly heated to the temperature higher than 2000 DEG C, and performance of the carbon particle raw materials can be greatly improved.
Description
Technical field
The utility model belongs to the metallurgical engineering field, is specifically related to a kind of high temperature electric forge furnace.
Background technology
The electricity forge furnace is in the metallurgical industry, the stove equipment that charcoal crude granule raw materials such as anthracite, petroleum coke, pitch coke, metallurgical coke, the roasting of charcoal piece be broken are heat-treated.Electricity forge furnace integral body is the tubular structure of vertical hollow, and the charcoal crude granule is added continuously from electric forge furnace top, discharges continuously in electric forge furnace bottom.The top of electricity forge furnace is provided with upper electrode, and the bottom is provided with lower electrode, when the charcoal crude granule passes through the body of heater cavity from top to bottom, and electric forge furnace energising, charcoal crude granule itself forms the heating of the resistance bed of material, utilizes electric energy to carry out self heating.The electricity forge furnace can be heat-treated to charcoal crude granule raw material average more than 1700 ℃ by electric energy, thereby exclude impurity such as volatile matter in the charcoal crude granule, sulphur, nitrogen, simultaneously, improve the real density of charcoal crude granule, the resistivity of reduction charcoal crude granule, so that these charcoal crude granules are being used as carbon block for blast furnace, when aluminium is used the raw material of cathode carbon pieces, electric furnace charcoal piece and carburant, are having excellent performance.
In realizing the utility model process, the inventor finds that there is following technical problem in the common electrical forge furnace: exist thermograde radially in the stove, that is, the centre temperature can reach more than 2000 ℃ in stove, but at stove inner rim position, temperature can only reach 1200～1400 ℃.Charcoal crude granule quality after electricity is forged like this is inhomogeneous, thereby having limited with it is the carbon block for blast furnace of raw material, the raising that aluminium is used cathode carbon pieces, electric furnace charcoal piece and carburant performance, especially require very low senior carburant for sulfur content and nitrogen content, then can not make with this charcoal crude granule.Though, by improving in the common electrical forge furnace input power or prolonging the charcoal time of staying of crude granule in stove, can improve heat treatment temperature on the whole, but because common electrical forge furnace, its liner is built by laying bricks or stones with high-alumina brick, high-alumina brick can not bear for a long time and be higher than 1400 ℃ temperature, therefore, can't realize carrying out the charcoal crude granule in the even heat treatment that is higher than under 2000 ℃ with the common electrical forge furnace.
Summary of the invention
Given this, the utility model purpose is to provide the uniform electric forge furnace of temperature in a kind of heat treatment temperature height, the stove, and the charcoal crude granule quality of utilizing this electricity forge furnace to produce is even, can be used for making for sulfur content and the very low high-grade products of nitrogen content requirement.
For solving above technical problem, the technical scheme that the utility model provides is, a kind of high temperature electric forge furnace is provided, and comprises a body of heater, and body of heater comprises a heat treatment section, and the heat treatment section is followed successively by furnace shell, the carbon black insulation bed of material, brick fuel inner liner from outside to inside.
Further, described body of heater also comprises a preheating section, and this section is followed successively by furnace shell, high-alumina brick inner liner from outside to inside.
Further, the gross thickness of the thickness of described high-alumina brick inner liner and the carbon black insulation bed of material, brick fuel inner liner is suitable.
Further, described body of heater also comprises a cooling section, and this section internal layer is graphite brick.
Further, the skin of described graphite brick is equipped with water collar.
Compared with prior art, a technical scheme in the technique scheme has following advantage:
1, the utility model high temperature electric forge furnace liner has adopted carbon black insulation material and brick fuel liner, having overcome high-alumina brick can't bear for a long time and to surpass 1400 ℃ high temperature, so that liner can be burnt out, send electrical power can reach 2000～2500KWH, local temperature near brick fuel can meet and exceed 2000 ℃, charcoal crude granule raw material in the stove can be heat-treated to more than 2000 ℃ uniformly, can improve the performance of charcoal crude granule raw material widely.Carbon material can bear more than 2000 ℃ for a long time, even the high temperature more than 3000 ℃, and at high temperature intensity increases, and possesses the condition as electric forge furnace liner.
2, the utility model high temperature electric forge furnace has adopted the carbon black insulation, has improved efficiency of utilization.
3, the utility model high temperature electric forge furnace has been built the higher graphite brick of thermal conductivity factor by laying bricks or stones at the body of heater salband, and thermal conductivity factor is up to 100～120W/ (m.K), and skin has increased cooling jacket, thereby has strengthened the cooling effect of material.
