Abstract
The utility model discloses a purging upper nozzle for continuous casting tundish, which has the advantages of high molding efficiency, little mechanical working, and low cost. According to the different endure properties, the utility model is divided into multi parts and these parts are vibration molded to form an integral body by friction press or hydraulic press and pouring materials. The utility model comprises a flow control bowl part (1), a purging part (2), and a pouring part (3), wherein, the purging part (2) is installed at the inner side of the upper nozzle and closely connected with the flow control bowl part (1) at the upper side and the pouring part (3) at the outer side. Employing this structure, the utility model enables to effectively increase the strength of the flow control bowl part, therefore improving the endure property for resisting the steel water erosion.
Description
Technical field
The utility model relates to the used auxiliary material of a kind of metallurgical continuous casting equipment, wraps ventilating filling pipe end in particularly a kind of continuous casting.
Background technology
Middle bag ventilating filling pipe end is positioned at the bottom of the tundish bag, links to each other with submersed nozzle, passes to gases at high pressure to filling pipe end during continuous casting, can prevent the nonmetal inclusion deposition, thereby guarantee that continuous casting carries out smoothly.Document number is that the patent documentation of CN1726106A discloses a kind of breathable refractory materials that is used for ventilating filling pipe end by name, the structure of the ventilating filling pipe end that the document is described as shown in Figure 1, this structure is to form by the resin-bonded composition common compacting around this ventilative resin-bonded composition with standard; Traditional ventilating filling pipe end mostly is the structure of whole isostatic compaction in the prior art, and the shortcoming of this structure is: the shaping efficiency of structure is low, die cost is high, machining amount is big and product cost is high; And the intensity of isostatic pressing product is also lower, causes life of product shorter.
Summary of the invention
Technical problem to be solved in the utility model provides in a kind of shaping efficiency height, machining amount is little and cost the is low continuous casting and wraps ventilating filling pipe end.
For solving the problems of the technologies described above, the utility model has been described a kind of being combined in the pattern continuous casting and has been wrapped ventilating filling pipe end, and it comprises: control stream bowl parts, means for ventilation, pouring piece; Described means for ventilation is positioned at the inboard of described filling pipe end, and with the described control stream bowl parts and the pouring piece sealed connection that lay respectively at the described filling pipe end upside and the outside, reserves air chamber between wherein said means for ventilation and the described pouring piece; Described pouring piece is provided with the sealing gland groove.
Described control stream bowl parts can be pressed for machine and do not burnt part; Described means for ventilation can be pressed for machine and be burnt till part; Described pouring piece can be for not burning pouring piece.
Above-mentioned each machine pressure part can be friction press or hydraulic press profiled part, and above-mentioned pouring piece can be cast material vibration moulding parts.
Preferably, described control stream bowl parts, means for ventilation can be by sealed connections such as double buckle or chamotte, and adopt moulding by casting to connect to be integral body.
Preferably, described pouring piece outside can also comprise box hat.
Compared with prior art, the technical solution of the utility model has the following advantages: each building block that adopts friction press or hydraulic press moulding and water material feeding vibration moulding in the utility model, and shaping efficiency is higher; Each parts after compacting or the vibration moulding need not to carry out too much later stage machining, and the waste material that produces is less; The cost of producing the friction press of each parts or hydraulic press and cast mould therefor is very low, therefore and filling pipe end of the present utility model has only the part parts to carry out high-temperature process, and the whole cost of bag ventilating filling pipe end is lower and have an energy-conservation effect in the continuous casting described in the utility model; Difference according to middle each position serviceability of bag ventilating filling pipe end, be divided into a plurality of parts, and adopt friction press or hydraulic press and water material feeding vibration moulding, become as a whole, can improve intensity effectively like this, thereby improve the performance of flushing of its anti-molten steel.
And the utility model is owing to adopt friction press or the hydraulic press moulding, and product bowl portion intensity is apparently higher than waiting static pressure product, thus in the continuous casting of the present utility model the service life of bag ventilating filling pipe end longer.
Description of drawings
Fig. 1 is the structural representation that wraps ventilating filling pipe end in the prior art in the continuous casting;
Fig. 2 is the structural representation of bag ventilating filling pipe end in the continuous casting described in the utility model.
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments the utility model is elaborated.
Referring to Fig. 2, the bag ventilating filling pipe end comprises in the continuous casting described in the utility model: control stream bowl parts 1, means for ventilation 2, pouring piece 3, described control stream bowl parts 1 can be pressed for machine and do not burnt part, and described means for ventilation 2 can be pressed for machine and be burnt till part, and described pouring piece 3 can be for not burning pouring piece.
Described control stream bowl parts 1 are positioned at the top of filling pipe end shown in Figure 2, contact with the stopper that steel stream is controlled, and it adopts mechanical pressing, has higher-density and intensity, has fully satisfied the control of stopper to steel stream.
Preferably, described mechanical pressing can be friction press or hydraulic press moulding.
Described means for ventilation 2 is positioned at the inboard of filling pipe end shown in Figure 2, and connects with the bottom of described control stream bowl parts 1; Described means for ventilation 2 adopts mechanical pressing, after Overheating Treatment, has satisfied the demand of breathing freely in the steel pouring process, and its back 3 is owing to for the high densification of moulding by casting does not burn part, reduced the loss of mouth of a river internal gas back pressure effectively.
Preferably, described mechanical pressing can be friction press or hydraulic press moulding.
Described pouring piece 3 is positioned at the outside of filling pipe end shown in Figure 2, and flows the bottom of bowl parts 1 and the outer type of described means for ventilation 2 with described control; Described pouring piece 3 adopts moulding by casting.
Preferably, described moulding by casting can be the vibration moulding of cast material.
Can carry out sealed connection by double buckle, chamotte etc. between described control stream bowl parts 1, means for ventilation 2, the pouring piece 3 and wrap ventilating filling pipe end in the complete described continuous casting to constitute, reserve air chamber 4 between wherein said means for ventilation 2 and the described pouring piece 3, described air chamber can be certain clearance; Described pouring piece 3 further comprises sealing gland groove 6; Described pouring piece 3 outsides also comprise box hat 5.
More than in the continuous casting of the present utility model the bag ventilating filling pipe end be described in detail; for one of ordinary skill in the art; according to design of the present utility model, on the specific embodiment, all can make improvement, combine the protection domain that can not exceed the utility model claims.
