Description
Technical field
The utility model belongs to field of metallurgy.Particularly; The utility model relates to a kind of ladle bag mouth monolithic molding device; Said mammoth conveter can overcome the deficiency of the bag mouth integral forming method that in the past adopted two kinds of methods of ramming and spraying with ladle bag mouth monolithic molding device; Make ladle bag mouth behind the global formation have enough compactness increasing its intensity, and construction is simple and easy to do relatively.
Background technology
At present, mammoth conveter generally has at least one to fall the bag mouth that iron uses with ladle, and ladle is in the opposite direction skimmed if desired, then need have two ladle bag mouths as shown in Figure 1.At this moment, because ladle bag degree of lip-rounding shape is irregular, and ladle bag mouth has certain gradient, generally can't adopt the method for brick anti-material to carry out ladle bag mouth forming construction.
The method of generally taking at present is: uses the method for ramming mass ramming or is sprayed on ladle bag oral area position to spray paint with the spray paint machine, then, the use of after the super-dry baking, reaching the standard grade.
Yet the technical problem that above-mentioned two kinds of methods all exist is, can't make that refractory material is enough closely knit resists the adhesion of washing away of molten iron when clearing up with ladle bag mouth.Thus, the ladle bag mouth that causes said method to be shaped, its service life is relatively low.Often generation can't can not synchronous problem of life-span with the ladle body, influences the ladle whole service life of anti-the material.
The utility model content
In order to overcome the problems referred to above; The purpose of the utility model is: a kind of ladle bag mouth monolithic molding device is provided; Said mammoth conveter can overcome the deficiency on two kinds of methods of said ramming and spraying with ladle bag mouth monolithic molding device; Make ladle bag mouth material enough compactness arranged increasing its intensity, and the utility model construction is simple and easy to do relatively.The mammoth conveter of the utility model is specially adapted to need on a ladle, to form the occasion of two bag mouths with ladle bag mouth monolithic molding device.
For achieving the above object, the technical scheme of the utility model is following:
A kind of ladle bag mouth monolithic molding device; Be used for the shaping of mammoth conveter with ladle bag mouth; It is characterized in that; Said mammoth conveter comprises with ladle bag mouth monolithic molding device: perisporium and ladle bag mouth inner wall shape coincide and with the ladle bag mouth molding die of ladle bag mouth inwall nogging upper edge wedge-like engagement; The ladle bag mouth molding die of said perisporium and ladle bag mouth inwall nogging upper edge wedge-like engagement is a taper type, and the radial dimension of said taper type ladle bag mouth molding die is less than gap thickness of ladle bag mouth inwall size, and said gap thickness is 150-200mm.
According to the utility model; Said gap thickness is used for cast aluminum silicon carbide castable between the perisporium of ladle bag mouth molding die and ladle bag mouth inwall nogging; With the ladle bag mouth wall behind the formation monolithic molding, the desired thickness of anti-material that promptly need construct.
Based on the utility model, because of ladle bag mouth inwall has certain gradient, said ladle bag mouth molding die perisporium and ladle bag mouth inwall nogging upper edge wedge-like engagement, during use, reliable gravity effect and ladle bag mouth brick are close to.
Said ladle bag mouth monolithic molding device according to the utility model is characterized in that, the perisporium of the ladle bag mouth molding die of said and ladle bag mouth inwall nogging upper edge wedge-like engagement is a steel plate.
Said ladle bag mouth monolithic molding device based on the utility model is characterized in that said mammoth conveter also comprises with ladle bag mouth monolithic molding device:
Be arranged at said ladle bag mouth molding die below, be used to support the hoistable platform of said ladle bag mouth molding die.
Said ladle bag mouth monolithic molding device based on the utility model is characterized in that, said ladle bag mouth molding die is two of symmetry, connects with the cross girder steel in the middle of two said ladle bag mouth molding dies.
With ladle bag mouth monolithic molding device, it is characterized in that said cross girder steel is an angle steel according to the said mammoth conveter of the utility model.
Said ladle bag mouth monolithic molding device according to the utility model is characterized in that said cross girder steel is a channel-section steel.
Because the utility model adopts integrated poured method to realize; Therefore, the said mammoth conveter of the utility model is done two perisporiums and two moulds that wrap nogging upper edge wedge shape butt, also are connected with the cross girder steel with ladle bag mouth monolithic molding device according to bag degree of lip-rounding shape.During construction mould is placed on and builds by laying bricks or stones,, therefore, do not influence personnel and on hoistable platform, construct because said two moulds connect through girder steel with on the hoistable platform.
Said ladle bag mouth monolithic molding device according to the utility model is characterized in that, the side girder steel in the said cross girder steel adopts two.
Said ladle bag mouth monolithic molding device according to the utility model is characterized in that, said cross girder steel can adopt the nut and the screw rod that are spirally connected to regulate length.
According to the described a kind of ladle bag mouth monolithic molding device of the utility model, its operating position is following:
At first, with mould hang through cantilever or the handling of driving a vehicle to the Bao Kou position, be coated with of the adhesion of last layer butter on mould and the face that pours contacts with minimizing mould and material.Because mould both sides wedgewise leans on gravity effect and ladle bag mouth brick to be close to.Then, adjust mold height with hoistable platform.The connection of die steel beam does not influence personnel and on hoistable platform, constructs.
The fragment of brick that in the gap of mould and ladle bag mouth brick wedge shape butt position, adds after ramming mass perhaps cuts tamps, in order to avoid leak material in the casting process.Then, in mould and ladle box hat gap, add the aluminium silicon carbide pours that stirs in advance, use the shock club tamping while adding.The air dry maintenance after 24 hours the demoulding can drop into baking and use.
According to the utility model, a kind of ladle bag mouth integral forming method: its characteristic: according to ladle bag degree of lip-rounding shape do two can with bag nogging upper edge wedge shape butt and two moulds that are connected with the cross girder steel.During construction mould is placed on and builds by laying bricks or stones, owing to be that girder steel connects and do not influence personnel and on hoistable platform, construct with on the hoistable platform.Reach optimum height through regulating hoistable platform, in mould and iron Baogang shell gap, add the pours that stirs in advance, and can drop into baking with the demoulding after shock club tamping, the air dry and use.Reduce workmen's labour intensity simultaneously.In addition, can improve the compaction rate of ladle bag mouth refractory material, all more closely knit than ramming and spraying method through the pours of shock club tamping, reduce in the hole of holding one's breath, and intensity increases.The workmen does not have the work of too big intensity in the while work progress.Except a mold needed to make separately, other equipment can both be built the shared extra increase that do not need by laying bricks or stones with ladle.Easy and simple to handle, small investment, effect are obvious.Can improve bag mouth and the ladle body synchronism in anti-material life-span.
