Abstract
The invention provides a metering nozzle quick-change device for a tundish. The metering nozzle quick-change device comprises a chassis fixed on the bottom face of the tundish; an opening which is used for clamping an upper nozzle brick is arranged on the chassis; a guiding device is fixed below the chassis; and a guiding groove which is used for placing a lower nozzle to be changed is arranged at an inner side of the guiding device. According to the invention, the change of the whole tundish is avoided through changing a metering nozzle, and the time for the process of changing the nozzle is shortened to 0.2 s, so that the efficiency is greatly increased, the service life of the tundish is prolonged, and a significant function for the continuity of molten steel casting is exerted.
Description
Technical field
The present invention relates to a kind of tundish metering nozzle fast replacing device, relate in particular to and a kind ofly in the molten steel casting process, continuous casting tundish metering nozzle is carried out quick-replaceable device.
Background technology
At present, be installed on the tundish between the tundish metering nozzle that steel mill uses, in the process of molten steel casting; Hole, the mouth of a river is easy to corroded by high-temperature molten steel, causes the brick at place, the mouth of a river to be damaged, and whole tundish just can not use; Must change tundish, cause whole tundish short service time, the replacing time is long; Also improved the cost of steel-making greatly, efficient reduces greatly.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, a kind of tundish metering nozzle fast replacing device is provided.
The object of the invention is realized through following technical scheme:
A kind of tundish metering nozzle fast replacing device; Comprise the chassis of being fixed in the tundish bottom surface; Offer the opening that is used to clamp upper nozzle brick on the said chassis; Below, said chassis is fixed with a guiding device, and said guiding device inboard is provided with and is used to place the guiding groove at the mouth of a river down to be replaced, an end on said chassis be connected with one be used to change down the mouth of a river the device of propelling.
Further, described tundish metering nozzle fast replacing device, the upper nozzle brick of wherein said fast replacing device become 45 degree oblique angles stacked up and down with the drift angle of lower nozzle brick.
Further, described tundish metering nozzle fast replacing device, wherein said chassis be about two and half dishes be fixedly connected, be provided with spring between said guiding device and chassis.
Beneficial effect of the present invention is mainly reflected in: through the replacing to metering nozzle; Removed from and changed whole tundish, and the process time weak point of changing the mouth of a river reaches 0.2S, improved efficient greatly; Prolonged the service life of tundish, the continuity of molten steel casting has been played a significantly greater role.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Fig. 1: tundish metering nozzle fast replacing device structural representation of the present invention.
The A-A cross-sectional view of Fig. 2: Fig. 1.
The assembling sketch map of Fig. 3: Fig. 1.
Wherein:
12 times mouths of a river of 1 half dish 11 filling pipe ends
2 guiding devices, 21 guiding grooves, 3 springs
4 axostylus axostyles, 5 fixed bars, 6 bolts
The specific embodiment
The present invention has disclosed a kind of tundish metering nozzle fast replacing device; As shown in Figure 1, shown in Figure 2, comprise by about two and half dishes 1 connect to form; Chassis for fixing to the tundish bottom surface; Offer the opening that is used to clamp upper nozzle brick on the said chassis, the below, chassis is fixed with a guiding device 2, and guiding device 2 inboards are provided with and are used to place the guiding groove 21 at the mouth of a river 12 down to be replaced.Be provided with spring 3 between said guiding device 2 and chassis.
The concrete assembling of this invention is as shown in Figure 3, about partly coil 1 and upwards fix at X through fixed bar 5 and bolt 6, the Y direction, fixed bar 5 passes fixing hole and is connected with spring 3 and guiding device 21 downwards in turn, simultaneously, makes progress at Z, connects through axostylus axostyle 4.This device is fixed in the bottom of tundish, newly descends the mouth of a river to place in the guiding groove 21, after the mouth of a river 12 is corroded instantly, then through catapult-launching gear (meaning not shown in the figures) replacement is directly ejected at the new mouth of a river down in the guiding groove 21 and damages the mouth of a river.The whole working time only needs 0.2S.Removed from and changed whole tundish, improved efficient greatly, prolonged the service life of tundish, the continuity of molten steel casting has been played a significantly greater role.
One end of this device be provided with one be used to change down the mouth of a river cylinder (meaning not shown in the figures), the following mouth of a river that will damage through cylinder action is ejected the back replacement and is gone up the new following mouth of a river.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming all drop within the scope of requirement protection of the present invention.
