Abstract
The utility model relates to a device for preventing a tundish permanent lining from being damaged. The device comprises a permanent lining, enclosing boards, a buffer spring and a steel shell, wherein the enclosing boards comprise the enclosing board I and the enclosing board II; an upper groove is formed at one end of the enclosing board I; the other end of the enclosing board I is fixedly arranged on the steel shell at the outer side of the permanent lining by a bolt; a lower groove is formed on one surface of the enclosing board II; the other surface of the enclosing board II is fixedly arranged on the upper-edge end surface of the permanent lining; the enclosing board I and the enclosing board II are fixedly connected by the buffer spring between the upper groove and the lower groove; the buffer spring is 45mm-55mm; the elastic force of the spring is larger than or equal to 135 KN; and the thickness of the steel shell is 35mm-45mm. Compared with the prior art, the device for preventing the tundish permanent lining from being damaged has the beneficial effects that the structure is simple, the use is convenient, and the practicability is high strong; and the service life of the tundish permanent lining is effectively prolonged, the level degree of the upper edge of the tundish steel structure is ensured, the production cost is reduced, and the utilization rate of the tundish permanent lining is improved.
Description
Technical field
The utility model relates to the continuous casting technology field, particularly a kind of device that prevents the breakage of tundish permanent liner.
Background technology
China is big steel country, also be continuous casting big country simultaneously, the steel-making continuous casting tundish is important metallurgical reaction, raising along with the continuous casting level, the a large amount of use of dry type material tundish working lining is produced the end back when removing working lining when dry type material tundish permanent liner, adopts tipping table to realize the disengaging of working lining and permanent liner by the upset roof pressure more, tundish is subjected to gravity effect to cause the distortion of tundish permanent liner damaged easily in switching process downwards, the service life of reducing the tundish permanent liner.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to use, improves the service life of tundish permanent liner, the device of prevention tundish permanent liner breakage.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of device that prevents the breakage of tundish permanent liner, comprise permanent liner, coaming plate, buffer spring and box hat, described coaming plate is made up of coaming plate one and coaming plate two, one end of coaming plate one is provided with groove, the other end of coaming plate one is by on the box hat that is bolted to the permanent liner outside, the one side of coaming plate two is provided with lower groove, and the another side of coaming plate two is fixed on the upper edge end face of permanent liner, and coaming plate one and coaming plate two are fixedly connected by the buffer spring between last groove and the lower groove.
Described buffer spring be 45-55mm, its spring force is more than or equal to 135KN.
Described box hat thickness is 35-45mm.
Compared with prior art, the beneficial effects of the utility model are:
A kind of device that prevents the breakage of tundish permanent liner, have simple in structure, with low cost, easy to use, practical characteristics, effectively raise the service life of tundish permanent liner, guaranteed the levelness of tundish steel construction upper edge, reduce production cost, improved the utilization rate of tundish permanent liner.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further specified:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of device that prevents the breakage of tundish permanent liner of the utility model, comprise permanent liner 1, coaming plate, buffer spring 5 and box hat 2, described coaming plate is made up of coaming plate 1 and coaming plate 24, one end of coaming plate 1 is provided with groove 7, the other end of coaming plate 1 is fixed on the box hat 2 in permanent liner 1 outside by bolt 6, the one side of coaming plate 24 is provided with lower groove 8, the another side of coaming plate 24 is fixed on the upper edge end face of permanent liner 1, and coaming plate 1 and coaming plate 24 are fixedly connected by the buffer spring 5 between last groove 7 and the lower groove 8; Described buffer spring 5 be 45-55mm, its spring force is more than or equal to 135KN; Described box hat 2 thickness are 35-45mm.
When the utility model is installed, after permanent liner 1 is made and is finished, box hat 2 is fixed on the outside of permanent liner 1, again coaming plate 24 upper edges are arranged, one end of buffer spring 5 is fixed in the lower groove 8, the other end of buffer spring 5 is fixed in the groove 7, and an end of coaming plate 1 and coaming plate 24 are linked together, and utilizes bolt 6 that the other end of coaming plate 1 is fixed on the box hat 2 then.
Above described only be basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
