Description

A kind of secondary metal smelting furnace
Technical field
The utility model is related to a kind of smelting system more particularly to a kind of secondary metal smelting furnaces.
Background technology
Smelting furnace be include the metals such as aluminium regeneration melting ingot casting system it is indispensable or device, the shape of smelting furnace, knot The consumption etc. of structure composition, the operational efficiency for not only directly affecting smelting system, fuel, such as smelting furnace material fluidity, furnace chamber pressure Uniformity coefficient of power and temperature etc.;But also smelting technology operation being directly affected, such as the maintenance maintenance scarfing cinder of smelting furnace, this is right Yu Danlu or structure composition it is not reasonable more stoves combination, influence it is all the more apparent.For example existing smelting furnace is due to its furnace body The reasons such as the shape and structure of inner cavity, if the shape at its bottom wall position is in reversed trapezoidal shape, not only scarfing cinder is inconvenient, needs to spend Time is long, and scarfing cinder is painstaking, scarfing cinder is not clean, influences production efficiency.Also, due to its internal structure external structure etc., scarfing cinder Process also impacts ambient enviroment, and Metal Melting slag falls completely or scald people, exactly punctures tire of mucking haulage.In addition, by In the high temperature and particularity of Metal Melting, bad setting has adjustable for height discharge portion, in this case, existing molten The Liu Tangkou of furnace(Metal smelting liquid floss hole)Setting structure is unreasonable, and causes the discharge of melting liquid and submergence absolute altitude There are contradictions with furnace chamber scarfing cinder, it is impossible to mutually coordinated cooperation.Scarfing cinder is inconvenient or immersion metal absolute altitude is limited, and shadow Submergence Smelting Effect is rung, energy consumption is increased and reduces production efficiency.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, providing a kind of secondary metal smelting furnace.This is again Raw metal smelting-furnace theory structure is simple, reasonable, can improve melting ingot casting production on-site environment, can also improve life to a certain degree Efficiency is produced, and scarfing cinder is more simple and convenient, reduce labor intensity;Meanwhile with preferably Smelting Effect and higher molten Efficiency is refined, adaptability is good, strong applicability.
The technical solution of the utility model secondary metal smelting furnace includes furnace body, described set on the breast hole of the furnace body Furnace body includes skeleton layer and internal layer, and the skeleton layer includes refractory brick course, further includes guiding device, the guiding device includes One is connected to the furnace body or the slag-guiding plate of the furnace body is connected to by attachment device, and the slag-guiding plate is correspondingly arranged at described clear The lower part of cinder notch, the slag-guiding plate, which tilts down, protrudes from corresponding furnace body outer wall face.
Its attachment device of the slag-guiding plate includes being opened in the coupling recesses of the lower part of the stream soup mouth of the furnace body, Yi Jihang Walk formula bearing support.
The utility model secondary metal smelting furnace due to shape and structure advantages of simple in its furnace chamber, scarfing cinder is simple and convenient, Quickly, it is time saving and energy saving, and scarfing cinder overall process is not in scaling-off in Workplace ground always, not only improves safety, but also Improve production environment;Which solve molten metal is needed to drain when scarfing cinder or maintenance to submerge with melting production process molten metal simultaneously The problem of absolute altitude requirement is conflicting.This secondary metal smelting furnace has relative productivity high and energy saving, is adapted to not of the same race Class, characteristic raw material regeneration melting.The resistance to body corrosivity of its inboard wall of furnace body is strong, and maintenance cost is low, repair takes a short time, and makes Use long lifespan.
Description of the drawings
Fig. 1 is one example structure schematic diagram of the utility model secondary metal smelting furnace.Fig. 2 is the utility model regeneration gold Belong to another example structure schematic diagram of smelting furnace.Fig. 3 is the utility model secondary metal smelting furnace another embodiment structural representation Figure.Fig. 4 is the guiding device structure diagram in another embodiment of the utility model.
