Abstract
A cupola with a thin water-cooling furnace brick lining includes a vertically arranged cupola body, a front cupola arranged at one side of the lower section of the cupola body, an upper exhaust opening system mounted on the lower section of the cupola body and a cupola wall water-cooling system arranged in the middle section of the cupola body; the cupola body includes the cupola body at the upper exhaust opening section of a lower section, the cupola body of the thin furnace brick lining of a middle section and the cupola body of a pre-heating section of an upper section. The cupola has the advantages of compact structure, long continuous working time, high water-cooling effect, high thermal efficiency, good melting technical property, good stability, low cost, energy saving and environment pollution reducing. The utility model can be broadly applied in the melting process of molten iron during the casting industry.
Description
Affiliated technical field the present invention relates to a kind of water-cooled thin-lining furnace cupola, can be widely used in the fusion process of casting industry molten iron.
Background technology
Existing common furnace lining furnace cupola adopts conventional furnace lining, last exhaust outlet above to the refractory thickness below the preheating section greater than 230 millimeters, furnace lining is thicker.When work, it is insufficient to burn, and energy dissipation is serious, and the effective rate of utilization of heat is low, furnace wall iron easy to hang, dross, and the smelting technology poor performance, the water cooling weak effect, stream time is short, and the refractory consumption rate amount is big, and maintenance time is long, and environmental pollution is big.
Summary of the invention
The water-cooled thin-lining furnace cupola that the object of the present invention is to provide that a kind of compact conformation, stream time are long, the water-cooled effect is strong, the thermal efficiency is high, the smelting technology performance is good, good stability, cost are low, energy-conservation, reduces environmental pollution.
In order to achieve the above object, water-cooled thin-lining furnace cupola of the present invention comprises the body of heater of vertical installation, is installed in the forehearth of body of heater hypomere one side, is installed in the last exhaust outlet system of body of heater hypomere, is installed in the furnace wall water cooling system in body of heater stage casing; Said body of heater comprises the last exhaust outlet section body of heater of hypomere, the thin-lining body of heater in stage casing, the preheating section body of heater of epimere.
Water-cooled thin-lining furnace cupola of the present invention, its operation principle is: furnace charge adds in the stove from the gallery ports of charge door body, at pack into the coke of certain altitude of restoration of lower stack, after lighting, the air of being sent by air blast enters all presses bellows, is blown in the coke combustion-supporting by the air port conduit after all pressing.The order of pressing lime stone → iron charge → coke (coke charge) on coke (bed coke) adds furnace charge; Iron charge is preheated fusing, and is superheated to more than 1500 ℃ in molten iron drippage process, goes into forehearth from the gap bridge orifice flow of furnace bottom; In melting, cooling water pumps into the furnace wall water cooling system by water pump, to the furnace wall spray, takes away a part of heat, makes furnace lining keep lower temperature.Level-sensing device is measured material level in the stove at any time, and sends " full material " or " feeding in raw material " signal to charging (feeding) equipment, and the control furnace cupola keeps completely expecting duty.Flue gas and dust that the stove internal combustion produces arrive spark catcher through chimney, because flue gas falls off, make the bulky grain dust that suspends in the flue gas and the coke chip of burning, are deposited on the wedged bottom and have ash releasing tube to get rid of.
Water-cooled thin-lining furnace cupola of the present invention, vertical structure, floor space is little, and parts are few, compact conformation.
Water-cooled thin-lining furnace cupola of the present invention, supporter is installed on the charging scffold, support the weight of upper component, when the shaft expanded by heating stretches, be not subjected to the restriction of charge door with upper member, thereby slow down the erosion of fire proof material of furnace lining, make the furnace cupola can continuous smelting more than 16 hours, can reach a week in case of necessity.Therefore, stream time is long.
Water-cooled thin-lining furnace cupola of the present invention adopts water-cooled thin-lining structure, compares with common furnace lining furnace cupola, and the water-cooled effect is strong.
Water-cooled thin-lining furnace cupola of the present invention, but the long-time continuous melting makes full use of lasting, stable heat, the effective rate of utilization height of heat, therefore, thermal efficiency height.
Water-cooled thin-lining furnace cupola of the present invention, adopt water-cooled thin-lining structure, the erosive velocity that fire proof material of furnace lining has been slowed down in the thin furnace wall of water-cooled, make furnace diameter remain on very little excursion for a long time, formed stable fusing environment, thereby make the stable performance of furnace cupola, air supply velocity and melting intensity change very little.Water-cooled thin-lining structure, one side can significantly improve the effect of water-cooled, on the other hand, compares with liningless cupola, has reduced the sensitiveness of cooling water flow again, has prevented that the furnace wall from hanging iron, the excessively generation of dross phenomenon, makes furnace cupola have more the stability of operation.Even the short time cooling water stops, also can not destroy the normal smelting of furnace cupola.Therefore, the smelting technology performance is good.
Water-cooled thin-lining furnace cupola of the present invention, thin-lining thickness are meant that exhaust outlet is above to the lining thickness of preheating section with the lower part.Adopt water-cooled thin-lining structure, the thickness of general thin-lining only is 1/3～1/2 of normal furnace lining, and promptly lining thickness has reduced refractory consumption rate between 40mm～230mm, and the refractory consumption rate expense is low, has alleviated maintenance load, and cost is low.
Water-cooled thin-lining furnace cupola of the present invention, all press the middle band balancing orifice plate of bellows, make the air feed pressure difference in each air port minimum, guaranteed the air intake ratio in each air port, thereby guaranteed abundant, even, the reasonably burning of bed coke, molten iron temperature is stabilized in more than 1500 ℃, saves coke fuel, reaches purpose of energy saving.
Water-cooled thin-lining furnace cupola of the present invention because the lining wear amount is very little, is compared with common furnace lining furnace cupola, and slag amount significantly reduces, and has reduced heat waste and environmental pollution.
Water-cooled thin-lining furnace cupola of the present invention, its advantage of thin-lining are to make the erosion of furnace lining to reach balance, guarantee that the fusion zone of furnace cupola is stabilized in certain scope, have increased the stability of cupola melting process.
Water-cooled thin-lining furnace cupola of the present invention, the refractory material of thin-lining furnace cupola can be that moulding refractory brick is built by laying bricks or stones, also can use amorphous refractory, as water material feeding cast or ramming mass ramming.
In sum, water-cooled thin-lining furnace cupola of the present invention, compact conformation, stream time is long, and the water-cooled effect is strong, thermal efficiency height, the smelting technology performance is good, good stability, cost is low, and is energy-conservation, reduces environmental pollution.
