Abstract
The invention provides a kind of new automatic casting apparatus, this apparatus features is that filler is contained in the tube in advance, and tube is inserted in the filling pipe end.
When molten steel entered ladle, owing to be plugged with this device in the filling pipe end, so molten steel just can not condense in filling pipe end, when opening slide gate nozzle, the filler in this device had just flowed, and molten steel just flows through the realization automatic casting from tube.Because it is the filler to filling pipe end dress is good by wound packages, just can carry out from the rear of ladle so this device is installed, very convenient, save trouble.
Description
Patent of the present invention relates to a kind of ladle nozzle automatic casting apparatus, particularly slide gate nozzle automatic casting apparatus.
The steel that waters of ladle is to realize by the switch at the mouth of a river, the mouth of a river of using mostly is a slide gate nozzle at present, it is made up of parts such as filling pipe end, upper slide, lower skateboards, the effect of filling pipe end is to have molten steel to guide to the slide plate place of slide gate nozzle in the bag, because the bottom of ladle is lined with refractory brick, so the thickness at the bottom of the whole ladle is very big, so filling pipe end must have certain length.After molten steel injected ladle, a part of molten steel had just flowed in the filling pipe end, solidifies because of cooling soon, and when opening slide gate nozzle, molten steel just can not automatic casting.
For addressing this problem, common way is to insert filler in filling pipe end, makes molten steel can't enter filling pipe end, also just can inside not solidify, stop up, and so just opens easily and has watered.But still there is following problem in this method: automatic casting ratio is lower, between 50%-90%, loads filler besides and will carry out work on scorching hot ladle, and the abominable labour intensity of environment is big.
The purpose of patent of the present invention provides a kind of improved automatic casting apparatus, and it can prevent solidifying of molten steel effectively, and guaranteeing at every turn can both automatic casting, and the work of filling material is fully simplified, and reduces labour intensity.
Patent of the present invention is achieved in that at filling pipe end fills in a tube, and this is that inside has filler, seal at two ends.When molten steel injects ladle, because filling pipe end is taken by filling tube, so molten steel can't enter filling pipe end, also just can not molten steel solidification have been arranged, when opening slide gate nozzle, the lower sealing of filling tube is opened, its inner filler all drops out under the effect of gravity, molten steel just crushes and seals, and flows out automatically, has realized automatic casting.Because its form that filling tube is special processing to be manufactured is fixed, the filler in the tube also installs as requested in advance, so the automatic casting ratio of this device is very high.Filling tube is very easy to the installation of wrapping, and at the rear portion of ladle, gets final product in the insertion filling pipe end in the upper slide hole, has so just greatly improved operating environment, has reduced labour intensity.The filler of filling tube inside, can be only at the very thin high temperature resistant filler of one deck of top dress, and, low-melting filler harmless to steel can be used in the bottom, also available one section support harmless to molten steel, like this, opening when watering,, also can not influence the quality of steel even if these fillers or support have been fallen in the molten steel.The available general refractory material of filling tube itself is made; also other material; it can open water after; dashed by molten steel through after a while and to melt or to burn so that next time, new tube was installed because filling tube do not washed out or burnt down before during this period of time; molten steel flows through in filling tube; directly do not wash away filling pipe end,, can improve the service life of filling pipe end so this automatic casting apparatus also has protective effect to filling pipe end.
Below with reference to accompanying drawing patent of the present invention is described in further detail.
Fig. 1 is the location drawing of automatic casting apparatus in ladle.
Fig. 2 is the automatic casting apparatus of interior filling material.
Fig. 3 is the automatic casting apparatus of interior filling material and supporter combination.
This device comprise filling tube (1), filler (2), supporter (5), on seal (3), lower sealing (4), since this device be inserted in the hole of filling pipe end (9), when so molten steel enters ladle (7), just can not flow in the hole of filling pipe end (9), just can not occur condensing, clogging yet.Open lower skateboard (6), when promptly opening slide gate nozzle, the lower sealing of this device (4) also is opened, filler wherein (2) or supporter (5) just can fall down, molten steel will damage by pressure and seal (3), and flow out the inside of self filler tube (1), realizes automatic casting.This device is very convenient when ladle (7) is gone up installation, it is inserted the filling pipe end (9) get final product in the hole of upper slide (8).
Claims (3)
1, a kind of steel ladle sliding water gap automatic casting apparatus, it comprises filling tube (1), filler (2), on seal (3), lower sealing (4), supporter (5), it is characterized in that the position of this device is to be contained in the hole of filling pipe end (9) and upper slide (8).
2, according to the described automatic casting apparatus of claim 1, it is characterized in that filler (2) is equipped with in the inside of filling tube (1), or the composition of filler (2) and supporter (5).
3, by the described automatic casting apparatus of claim 1, it is characterized in that the external diameter of filling tube (1) is greater than the aperture of lower skateboard brick (6).
