Abstract

The utility model provides an improved liquid-steel pouring ladle gate, which comprises an installation plate arranged on the connection plate of a liquid-steel ladle, a sliding frame supporting a lower gate plate and a spring tightly pushing device. The spring tightly pushing device is composed of a spring, a spring box, a spring rack and a toggle lever. The toggle lever uniformly pressurizes and tightly closes an upper gate plate and a lower gate plate by the spring. The inner of the sliding frame is screwed with the tightly pushing device of a lower sleeve pipe. The tightly pushing device is composed of a tightly pushing device and a tightly pushing sleeve. The circumferences of the upper gate plate and the lower gate plate are hooped with metal and the bottom parts are adhered with metal asbestos plates or metal iron shells. The shape of each gate plate is an orbicular shape or an arris shape. The structure of the gate can effectively prevent steel leakage with the advantages of high safety and reliability.

Description

A kind of gate of molten steel casting ladle of improvement

The utility model relates to a kind of gate of metal casting ladle, the anchor gate of the molten steel casting ladle of more specifically saying so.

The gate of existing molten steel casting ladle, FHK-2C type (Fig. 1, shown in Figure 2) as Shanghai, this class molten steel casting ladle lower flashboard and setting of casing connect together and are assembled in the iron sheet cover, because assembling quality or the iron sheet cover rubescent generation plastic deformation of being heated in use make seam between lower flashboard and the setting of casing enlarge to produce to ooze steel; And the gate structure spring of this kind molten steel casting ladle is arranged in the slider bar below the lower flashboard, and spring directly contacts with lower flashboard, and spring is subjected to behind the high temperature fragile, causes bleed-out accident between the upper and lower flashboard; The flashboard of FHK-2C type is shaped as ellipse, and size is big, and materials are many.

The purpose of this utility model is to increase the setting of casing winding device on the basis of the gate mechanism of aforementioned this class molten steel casting ladle, guarantees that the gap between setting of casing and the lower flashboard is enough little; Improve the resiliency supported of sliding frame, make spring directly support flashboard change spring and support flashboard indirectly; Improve the shape of flashboard, its size is reduced.

Technical solution of the present utility model is: a kind of gate of molten steel casting ladle of improvement, has an installing plate 7 that can be contained on the ladle terminal pad 1, support the slider bar 15 and the spring top clamping device of lower flashboard, be rotary with the holding device of setting of casing 6 in the slider bar 15, this holding device is made of top-fastener 24 and tight sleeve 23, tight sleeve 23 and slider bar 15 match by screw thread, tight sleeve 23 also matches by line with top-fastener 24: described spring top clamping device is by spring 19, spring box 20, spring(-supported) mount 21 and angle lever 22 constitute, spring 19 is installed in the spring box 20, spring box 20 is installed in the spring(-supported) mount 21 of doorframe 11 both sides, angle lever 22 links to each other with axle 17, and angle lever 22 also links to each other with the key seat 12 of installing plate 7 with connecting rod 18 by pivot pin 14; Flashboard and metal shell that last lower flashboard (4,5) is made by refractory material constitute.

A kind of gate of molten steel casting ladle of improvement, hoop has a metal 25 around the lower flashboard on it (4,5), metal asbestos board or metal iron-clad 26 are pasted in the bottom, flashboard be shaped as oval or prismatic shape.

The structure that the utility model adopted can prevent the generation of bleed-out accident effectively, structurally with on the performance has safe and reliable advantage, has versatility on installing and operating.

Now in conjunction with the accompanying drawings and embodiments the utility model is described as follows:

Fig. 1 is the profilograph of FHK-2C shaped steel water casting ladle gate;

Fig. 2 is the drawing in side sectional elevation of FHK-2C shaped steel water casting ladle gate;

Fig. 3 is the utility model profilograph;

Fig. 4 is the utility model drawing in side sectional elevation;

Fig. 5 is the drawing in side sectional elevation of another state of the utility model;

Fig. 6 faces upward diagrammatic sketch for the utility model;

Fig. 7 is the utility model flashboard structure schematic diagram;

Fig. 8 is one of the utility model flashboard knot outline drawing;

Fig. 9 is two of the utility model flashboard knot outline drawing;

In the embodiment of Fig. 3 to Fig. 5, the terminal pad of 1 expression ladle bottom, in terminal pad 1, inserted a hollow brick 2, by bolt and alignment pin 8 terminal pad 1 and installing plate 7 are linked together, thereby the utility model molten steel casting ladle gate is fixed on the terminal pad 1, upper flashboard 4 places in the installing plate 7, be close to the last sleeve pipe 3 that places in the hollow brick 2, and with withstanding tight block 9, puller bolt 10 holds out against upper flashboard 4, prevent to come off, doorframe 11 is by installing plate pivot pin seat 12, doorframe hinge 13 is connected with pivot pin 14, lower flashboard 5 places slider bar 15, and tight sleeve 23 and slider bar 15 be by being threaded, and top-fastener 24 and tight sleeve 23 match with screw thread, setting of casing 6 is screwed in the tight sleeve 23 after top-fastener 24 matches, setting of casing 6 and lower flashboard 5 are adjacent to; Spring 9 places spring box 20, and spring box 20 is installed in the spring(-supported) mount 21, and by angle lever 22 lower flashboard 5 and upper flashboard 4 is adjacent to by spring 19 even pressurizations, and the ball pivot bar 16 on the slider bar 15 promotes lower flashboard 5 by the desired position that opens or closes; Upper and lower flashboard (4,5) side hoop has metal 25, bottom surface that the asbestos metal caul is arranged or is wrapped up by metal iron-clad 26; Also there is the iron-clad parcel at the following mouth of a river 6, and upper and lower flashboard (4,5) is shaped as avette or prismatic shape (as Fig. 8 and shown in Figure 9).
