Description
The present invention relates to a kind of plate and be assembled to structure on the metal framework the kalamein of tabular refractory material and so on, described plate is used for being contained in the sliding nozzle device on the container of deposite metal, and " plate " used herein speech comprises upper and lower plate in two plate member or upper plate and the lower plate in three plate member.
Mention the tabular refractory material that is used for sliding nozzle device, known notification number is the plate that the uncensored Japan Patent of 48-6932 discloses a kind of kalamein.From notification number be the uncensored Japanese Utility Model patent of 49-119422 and 52-115607 and the uncensored Japan Patent that notification number is 60-234765 as can be known, about how tabular refractory material being assembled in the metal framework, some of the recommendations have been proposed so far.
At notification number is in the uncensored Japan Patent of 1-218761, has proposed a kind of dependence with the concentric metallic sheath outside of the nozzle bore of sliding nozzle device and realizes the method that sliding panel is located, thereby simplified being connected of sliding panel and sliding metal framework.But, the shortcoming of this proposal is, because the outside of the metallic sheath that is used to locate is round the access hole of deposite metal, if therefore the temperature that the outside size of metallic sheath becomes between big and metallic sheath and the sliding metal framework in cooling procedure becomes too big, the gap between metal and the sliding metal framework will reduce so.And the known metal cover can be inserted among the metal framework dearly, and sliding panel can be killed sometimes, thereby harms the replacing of sliding panel.
Therefore, an object of the present invention is to provide and a kind ofly on metal framework, load onto or pull down fixed head easily or have the structure of the sliding panel of non-sliding surface.
Another object of the present invention provides a kind of structure, in this structure, even after the injection, also can change above-mentioned plate very stably under the still very high situation of the temperature of plate.
Another purpose of the present invention is to make above-mentioned plate in simple mode.
For achieving the above object, according to the present invention, the plate of kalamein with its sliding surface facing surfaces on be shaped on one or several projections.Each projection is made following shape, in the time of promptly in this projection is packed metal framework into, between this projection and the metal framework along have on the glide direction of plate a scope at 0.1mm to the fit tolerance between the 1.0mm, and, the diameter of the cylindrical part of each projection is less than 1/3rd of the width of plate, it highly is 1-5mm, and the bowl-shaped portion of projection links to each other with the top of cylindrical part.
When work, moving synchronously of plate and metal framework, and in order to simplify the replacing operation of plate, be formed on projection on the metallic sheath and make on the sliding surface facing surfaces that abuts against with plate, the outer shape of each projection become and metal framework between have a scope at 0.1mm to the fit tolerance between the 1.0mm.Preferably have a plurality of (with only one opposite) projection, rotate to prevent plate.
In addition, the influence of hot load when under the state of cooling, not sprayed for the projection that makes plate and the tolerance between the metal framework, the external diameter that makes each projection is all less than 1/3rd of the width of plate.And, because hot load, can between the projection of plate and metal framework and position that plate cooperates, cause the temperature difference usually during injection.That is to say that the temperature on the side of plate becomes greater than the temperature 20-100K on the metal framework side, thereby make the tolerance between plate and the metal framework on the glide direction of plate, reduce.Therefore, 1/3rd of the width by the external diameter of projection being reduced to plate just may reduce the difference of tolerance between the state of cooling and hot state.This has just prevented projection because tolerance becomes too big and asynchronous with the sliding metal framework, or since tolerance become too little and kill with the sliding metal framework.
In order to simplify the location of tabular refractory material with respect to metal framework, projection comprises a cylindrical part and a bowl-shaped portion that links to each other with the top of this cylindrical part, the diameter of described cylindrical part less than plate wide 1/3rd, and its height at 1mm between the 5mm.
For simplify plate on metal framework installation and pull down, each projection all has one highly to be the cylindrical part and a bowl-shaped portion that links to each other with the top of cylindrical part of 1-5mm.If cylindrical part, the height of mating part that also is projection are less than 1mm, it is just not firm to cooperate; And when height during greater than 5mm, plate on metal framework installation or just pull down to advance like that and pull out and seem inconvenient as drawer.In addition, when slide, the projection of plate not only is subjected to the effect of shearing force, but also is subjected to the effect of bending force, therefore can reduce the intensity of projection.In the time of in plate is packed metal framework into, the bowl-shaped portion that links to each other with the top of cylindrical part plays the effect of guiding.And, by forming bowl-shaped portion rather than make the cylindrical intensity that improves projection with cylindrical part simply, thereby the mobile of metal framework transferred on the plate reliably.
According to the present invention, for simplify plate on metal framework installation or pull down, when in course of injection, carrying out important positioning action, high-precision cooperation only is provided on glide direction, and on the direction vertical, leaves sizable gap value with glide direction.Like this, by this gap allowance, just simplified the dismounting of plate.
According to the present invention, for simplifying the manufacture process of plate, the projection of metallic sheath made abut against on sliding surface facing surfaces plate and plate, make the height of the cylindrical part of each projection be less than 5mm, and will make bowl-type with the part that the top of cylindrical part links to each other.These metallic sheath projections are matched with the recessed portion of metal framework.Also can on metal framework, form same projection, and on metallic sheath, form same recessed portion, but this set can cause the lay problem of tabular refractory material in metallic sheath.When forming recessed portion on metallic sheath, the thickness of adhesives that is used for connecting metallic sheath and refractory material is blocked up.The height that must comprise each recessed portion.This will make that the whole thickness of material is blocked up.In addition, also can originally form recessed portion on one's body, but because refractory material ftractures easily, therefore this method is worthless at refractory material.
As for the manufacture method of metallic sheath, considered that welding is arranged, forging, punching press, sheared or be used in combination these methods, but simple punch process is not only convenient but also efficient.When carrying out punch process, need use pressing mold, importantly avoid making the inappropriate mould of shape this moment.The mould that shape is suitable can increase the service life, thereby reduces cost.According to the present invention, each metallic sheath projection made comprise one at the height of the pressing direction cylindrical part less than 5mm, a bowl-shaped portion with certain curvature that links to each other with the top of this cylindrical part and a flare also have the part of the answer section of the thickness that keeps adhesives.
