This sliding nozzle device is being installed under the situation of tundish, though the type of not using intermediate plate is also arranged, usually from last upper nozzle, upper board, intermediate plate, lower panel and 5 refractory bodies of lower nozzle of disposing in order.
For these refractory bodies are installed on sliding nozzle device, on-line job and off line job are arranged.On-line job be the slip nozzle on being arranged at the bottom of the tundish then and there (online) open metal frame and operational method that refractory body is installed.Off line job is the operational method of the integral replacing sliding nozzle device (loading and unloading type sliding nozzle device) that releasably is installed on tundish, changes refractory body in the place of leaving tundish (off line).
Under on line state, refractory body is installed in job step on the sliding nozzle device, is undertaken by following step.At first, insert the upper nozzle of week coating mortar outside in the endoporus of the nozzle cage brick in tundish.And, upper board is pressed in the bottom of upper nozzle and is fixed on the metal frame of sliding nozzle device across joint filler., intermediate plate and lower panel be fixed on the metal frame of sliding nozzle device on thereafter, last, lower nozzle is pressed in lower panel and fixing with bayonet socket etc. across joint filler.
And at joint fillers such as configuration setting joint filler or mortar between upper nozzle and the upper board and between lower panel and the lower nozzle etc., need with the thickness of this joint filler preferably in the span of control of ± 1mm precision manage well.
But, especially there is the seam caliper problem of fluctuation easily between upper nozzle and the upper board in the variable that has the position of nozzle cage brick or interior hole dimension, the outside dimension of upper nozzle, the mortar coating amount of upper nozzle periphery, the hardness of mortar etc.When seam caliper is too small, then be easy to generate the gap in use, when seam caliper was excessive, then the loss of seam portion became the danger raising of big bleed-out.
In others, the past motion has the various replacing methods of refractory body.For example, the method as change plate under on line state records the fixed disk that waters on the incrustation with respect to being arranged in patent documentation 1, the method for changing when being maintained fixed plate with the sliding panel that is fixed on the sliding panel gripper shoe by the plate control stick.

Summary of the invention
The invention provides a kind of upper nozzle-integrated template that makes upper nozzle and upper board integration, when it uses in sliding nozzle device, the thickness at the junction surface between upper nozzle and the upper board can be suitably kept, and after use, upper nozzle and upper board can be unloaded simply.
Be conceived in sliding nozzle device, by not being fully fixedly between upper nozzle and the upper board, but the bonding force of the degree that comes off easily after using by not coming off when refractory body is installed is next bonding, can unload upper nozzle and upper board simply after use.
Promptly, upper nozzle-integrated template of the present invention is can separate upper nozzle and lower panel and from the upper nozzle-integrated template of molten metal container dismounting after use, it is characterized by, have in the bottom upper nozzle of metal part and the nozzle bore that has the upper board of metallic plate in the above match respectively below joint filler butt upper nozzle with above the upper board, engage the metal part of upper nozzle bottom and the metallic plate above the upper board by the welding more than 2 places, this weld seam waist height is below the above 5mm of 2mm, the adding up to below the above 60mm of 5mm of fusion length.
Upper nozzle-integrated template of the present invention only engages the metal part of upper nozzle bottom and the metallic plate above the upper board by the form that approaches spot welding more than 2 places, because just the bonding force of the degree that is come off easily by the bonding part engages, therefore when changing refractory body, can easily separate upper nozzle and upper board.
Metal part as the upper nozzle bottom is specially, and the viewpoint of upper nozzle body difficult drop-off is more preferably the metal shell that covers the bottom from the side of upper nozzle during from installation, or at the lower end of nozzle side configuration metal system jacket.
In addition, as the metallic plate above the upper board, though the viewpoint of upper nozzle body difficult drop-off is more preferably the metal shell that utilizes the top and side that covers upper board during from installation, also annular disk-shaped metallic plate can be installed on upper board.Say briefly, because the metallic plate of the upper board that the present invention said is used for being provided with the metal part weld bonds of upper nozzle bottom, therefore can at least only be configured in the soldered position above the plate, also can put up a plurality of metallic plates or bury the part of metallic plate underground.And, as the metal shell of covering side above upper board, also can around the upper board side, metal jacket or becket be set, welding covers the metallic plate above the upper board on this metal jacket or becket.
When welding upper nozzle and upper board, making the weld seam waist high is below the above 5mm of 2mm, and the adding up to below the above 60mm of 5mm of fusion length.Bonding force is not enough easily if the high not enough 2mm of weld seam waist then becomes difficulty on solder technology, if surpass 5mm, then compares with the thickness of the metal that uses and becomes blocked up and unrealistic.In addition, if the not enough 5mm of the total of fusion length, upper nozzle separates easily with upper board when then operating, and is if surpass 60mm, then not easily separated after use.This weld seam waist high with the weld zone 6 of fusion length at upper nozzle shown in Figure 11 and upper board 2 in, the width S of weld seam is defined as weld seam waist height, the length L of weld seam is defined as fusion length.
In the present invention,, the method that pulls upper board or sliding nozzle device from the outside of molten metal container is arranged, reach the method that pulls the method for upper nozzle or release to the inside from the inboard of molten metal container as the method for separating upper nozzle and upper board.When pulling upper board, have by artificial use lever nail puller and wait the method for digging out plate, utilize power source such as hydraulic cylinder to pull the method for plate or sliding nozzle device.But, when the bonding force of welding is excessive, then, there is difficult drop-off in order to separate the very big power of weld zone needs, or the problem that deforms in the sliding nozzle device.
In addition, according to the shape or the execution conditions of upper nozzle, also can be by upper nozzle is dragged or released from the weld zone and unload to the molten metal container layback.And, also can be and unload upper nozzle simultaneously by drawing back the metal on being set at the bottom of the molten metal container.
Not easily separated for upper nozzle when when carrying or the execute-in-place with upper board, and after use, separate from the weld zone easily, the product W of total L2 (mm) that is more preferably high S of weld seam waist (mm) and fusion length is in the scope below 300 more than 25.The calculated value that W=25 is equivalent to weld the bonding force that is produced is about 0.5t (ton), and the calculated value that W=300 is equivalent to weld the bonding force that is produced is about 7t.In other words, if W less than 25, bonding force deficiency then has the possibility that comes off in carrying or in the operation, if W surpasses 300, then bonding force is excessive and the weld zone difficult drop-off might deform in sliding nozzle device.
In the present invention, because welding upper nozzle and upper board under the state of guaranteeing the gap between upper nozzle and the upper board in advance, therefore the seam caliper that is made of mortar between upper nozzle and the upper board is formed necessarily, can wait precision to manage seam caliper well by manufactory.Therefore, can eliminate the loss of the seam portion that causes owing to seam is blocked up, or owing to crossing thin cause the producing unusual melting loss of caused refractory bodies such as gap or the danger of bleed-out, stable operation.
In addition, this upper nozzle-integrated template is fit to be used in the loading and unloading type sliding nozzle device.This is because because the loading and unloading type sliding nozzle device for example is replaced chassis and pulls out as citing document 2 after use, therefore can utilize this pulling capacity to separate the weld zone of upper nozzle and upper board.If the pulling capacity deficiency of this loading and unloading type sliding nozzle device, the power that then strengthens power source and be motor or cylinder etc. gets final product.And, because can be installed in upper nozzle and sliding nozzle device simultaneously in the molten metal container, therefore also have the advantage of operating efficiency raising.
In addition, in the loading and unloading type sliding nozzle device,, utilize its hydraulic pressure to separate the welding of upper board and upper nozzle by between fixing metal frame and molten metal container, disposing plunger-type cylinder.Even the result also can unload sliding nozzle device in the hypodynamic loading and unloading type sliding nozzle device of drawing from molten metal container.
And, at the recess of fixing metal frame the lever nail puller is set and inserts and use groove, the lever nail puller is inserted into this lever nail puller inserts in usefulness groove, can dig out with easy method with the lever nail puller and separate upper nozzle-integrated template.Though can utilize lever principle to separate upper nozzle-integrated template by using the lever nail puller with easy method, but in order to carry out operation with a people's the power and the lever nail puller of use suitable length, the weld seam waist height that is more preferably the upper nozzle-integrated template that uses this moment is as below the above 4mm of 2mm, and the adding up to below the above 20mm of 10mm of fusion length.
And in order more easily to separate with the lever nail puller, the product W of total L2 (mm) that is more preferably the high S of weld seam waist (mm) and fusion length is in the scope below 100 more than 25.The calculated value that W=25 is equivalent to weld the bonding force that is produced is about 0.5t (ton), and the calculated value that W=100 is equivalent to weld the bonding force that is produced is about 2t.As long as in this scope, just can come separating plate to the power of 2 human lever nail pullers by 1 people.
Because can therefore can eliminate the danger of bleed-out or the unusual melting loss of refractory body, stable operation with the management of the seam caliper between upper nozzle and the upper board for certain.Therefore in addition, because can easily separate upper nozzle and upper board, can reduce and be used for upper board from time that molten metal container is dismantled.And because upper nozzle and loading and unloading type sliding nozzle device can be installed simultaneously, so operating efficiency improves.
