Abstract
A crucible cooling device in a vacuum induction melting furnace is formed by abutting a furnace body wind path system to a furnace cover wind path system. An outer furnace pipe penetrates through a furnace wall and is communicated with inert gas in the furnace to form a furnace body wind path system, the outer furnace pipe is connected with a fan outside the furnace, the fan is connected with a gas-cooled heat exchanger, and the gas-cooled heat exchanger is connected with a wind source pipeline in the furnace through a pipe. The wind source pipeline extends upwards along an inner furnace wall, an outlet of the wind source pipeline is abutted to an abutting horn mouth of a cool wind pipe arranged on the furnace cover, and the air outlet of the cool wind pipe arranged on the furnace cover aligns to a crucible. Under argon atmosphere, the crucible cooling device conducts wind cooling on the crucible after the crucible is naturally cooled to a certain temperature. In the wind cooling process, residual alloy steel liquid coagulation in the crucible is avoided to be oxidized and slagged, so that yield is improved, and residual alloy steel liquid compositions and ingredient compositions are ensured to be basically consistent.
Description
Technical field
The invention belongs to cooling device, be specifically related to crucible cooling device in the vacuum induction melting furnace.
Background technology
[0002] in rare earth permanent-magnetic material is made, ready metal material by a certain percentage, to become alloy cast ingot (tabular, laminar) be important production process to vacuum induction melting under vacuum state.Under the condition of continuous operation, often the temperature of ingot casting has reached the temperature that can come out of the stove, but the temperature in the crucible is still very high, or even the rubescent condition of high temperature.If under such state, open the body of heater discharging, then: the 1st, the temperature in the crucible is too high can't carry out follow-up operation sometimes; The 2nd, under high like this temperature, the solid alloy of residual various forms and easy oxidative slagging thereof cause yield to reduce in the crucible, and the composition of residual alloy departs from.
Summary of the invention
In order to enhance productivity, make the cooling velocity of the cooling velocity of crucible and ingot casting synchronous, the oxidative slagging and the composition that reduce residual alloy depart from, and the utility model provides vacuum induction melting furnace crucible cooling device.
The utility model utilizes protective gas in the existing vacuum induction melting furnace stove, and protective gas is transported to outside the stove by pipeline, and heat exchange outside stove is after be transported to the bell airduct that is positioned on the bell by pipeline, the air outlet aligning crucible of bell airduct.
Concrete structure of the present utility model is made of body of heater air path system and the butt joint of bell air path system, wherein the bell air path system is the wind regime pipeline that is arranged on the bell, the body of heater air path system passes the furnace wall for the stove Outer Tube and is communicated with inert gas in the stove, the stove Outer Tube is connected with stove blower fan outward, blower fan connects air cooling heat exchanger, air cooling heat exchanger is connected with wind regime pipeline in the stove by pipeline, the wind regime pipeline makes progress along internal protecting wall, the delivery outlet of wind regime pipeline docks the horn mouth butt joint with cool air hose on being positioned at bell, the air outlet of the cool air hose on the bell is aimed at crucible.
Air cooling heat exchanger adopts cooling driers or copper pipe heat exchanger, is used for cool cycles gas.
The utility model treats that crucible begins to carry out air-cooled to crucible after naturally cooling to uniform temperature under the argon atmosphere of melting.Because the atmosphere of cool cycles gas of this moment is the protective atmosphere of inert gas such as argon gas; in air-cooled process; avoid the coagulative oxidative slagging of residual alloy molten steel in the crucible, improve yield, also guaranteed the basically identical of residual molten steel component and food ingredient simultaneously.
The utility model is especially more effective for the big place of single furnace output.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Among the figure, 1, air inlet, 2, blast pipe, 3, air-cooled blower fan, 4, air cooling heat exchanger, 5, outer cool air hose, 6, the furnace wall, 7, cool air hose in the stove, 8, the butt joint horn mouth, 9, the cold wind air outlet, 10, the bell airduct, 11, bell.
The specific embodiment:
Embodiment: shown in Figure 1, present embodiment is made of bell air path system and the butt joint of body of heater air path system, the air inlet 1 of body of heater air path system is communicated with vacuum induction melting furnace, air inlet connects air-cooled blower fan 3 by blast pipe 2, connect air cooling heat exchanger 4 after the blower fan, air cooling heat exchanger 4 is a copper pipe heat exchanger, air cooling heat exchanger 4 penetrates the furnace wall by outer cool air hose 5, and be connected with cool air hose 7 in the stove, cool air hose 7 upwards is connected to the butt joint horn mouth 8 of bell air cooling system in the stove along internal protecting wall, bell airduct 10 is fixed on the bell 11, one end of bell airduct 10 be with the body of heater furnace wall in horn mouth 8, one ends that dock of cool air hose pipeline be connected to the cold wind air outlet 9 of aiming at bushing position.
When bell was opened, bell upwards rose earlier, and the wind path docking port breaks away from, and made things convenient for the side shifting backward of bell.When preparing melting, bell moves to and covers upper/lower positions, is positioned at butt joint horn mouth on the body of heater this moment on the docking port on the forced air cooled tube of body of heater furnace wall.After bell covered, horn mouth docked with the bell horn mouth.Docking port adopts has reasonable flexible vacuum gum cover, realizes docking with bell-mouthed, reduces the interface wind loss.
When needs cool off, open air-cooled air-cooler, the protective gas (inert gas) in the body of heater is inhaled into air path system.Afterwards along cold wind pipeline process mating interface and bell airduct, from the ejection of cold wind air outlet, the cold wind air outlet is aimed at crucible to inert gas through cooling heat exchanger in the stove that blower fan drove, and the cold wind of ejection sprays to crucible, and crucible is cooled off.
Cooling blower adopts variable-frequency governor to drive, and when beginning to cool down, crucible temperature is very high, and the cool cycles blower fan adopts the little air quantity cooling of the slow-speed of revolution to prevent the crucible cracking, progressively increases rotating speed then, improves the mode of air quantity and cools off.
