Abstract
A kind of continuous casting tundish of the utility model prevents that wearing packaging puts, comprise tundish involucrum, tundish permanent layer, dope layer, it is characterized in that arranging caisson at tundish bottom impact zone, caisson shell is connected with tundish involucrum, arranges two pieces of high aluminium-magnesia carbon bricks in caisson, be provided with tundish permanent layer between two pieces of high aluminium-magnesia carbon bricks, high aluminium-magnesia carbon brick Surface mulch is in dope layer.The utility model structure is simple, cheap, unpack difficulty and the high aluminium-magnesia carbon brick in one piece, bottom can not be caused to reuse because of dry slag, improves pouring box integral service life.
Description
Technical field
The utility model relates to a kind of continuous casting tundish and prevents that wearing packaging puts, and stops the large water-coating port impact zone of tundish and occurs wearing bag phenomenon.
Background technology
Existing conticaster when producing in large bag molten steel through excessive bag protective casing, then to wash away to tundish impact area basecoat.Owing to being subject to washing away for a long time and temperatures involved of molten steel, tundish impact area basecoat can be washed off by steel impaired, causes molten steel to corrode tundish paint layer and involucrum, passes, cause production and safety accident in tundish.And the dope layer of impact zone often just thickeies when building tundish processed by existing way, the not concrete precautionary measures, cannot avoid occurring that tundish wears bag accident.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of continuous casting tundish and prevents that wearing packaging puts, and reaches and prevents tundish impact area by the object of high-temperature molten steel erosion, burn through.
The utility model solves the technical scheme that its technical problem adopts: a kind of continuous casting tundish is anti-to be worn packaging and put, comprise tundish involucrum, tundish permanent layer, dope layer, it is characterized in that arranging caisson at tundish bottom impact zone, caisson shell is connected with tundish involucrum, arranges two pieces of high aluminium-magnesia carbon bricks in caisson, be provided with tundish permanent layer between two pieces of high aluminium-magnesia carbon bricks, high aluminium-magnesia carbon brick Surface mulch is in dope layer.
Above-mentioned tundish impact area settle two pieces of high aluminium-magnesia carbon bricks be specifically of a size of 800 millimeters × 800 millimeters × 200 millimeters, it can accept the erosion of washing away of high-temperature molten steel and slag, reaches the object preventing tundish from wearing bag.
The utility model advantage main manifestations is: structure is simple, cheap, can not cause because of dry slag difficulty of unpacking, and the high aluminium-magnesia carbon brick in one piece, bottom can reuse, and improves pouring box integral service life.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the top view of Fig. 1;
In figure: 1, tundish involucrum, 2, tundish permanent layer, 3, caisson, 4, high aluminium-magnesia carbon brick, 5, dope layer.
Detailed description of the invention
The utility model embodiment is: see Fig. 1: a kind of continuous casting tundish prevents that wearing packaging puts, comprise tundish involucrum 1, tundish permanent layer 2, dope layer 5, arrange caisson 3 at tundish bottom impact zone, caisson 3 shell is connected with tundish involucrum 1, arranges two pieces high aluminium-magnesia carbon bricks 4 in caisson 3, be provided with tundish permanent layer 2 between two pieces high aluminium-magnesia carbon bricks 4, high aluminium-magnesia carbon brick 4 Surface mulch is in dope layer 5.
The utility model can be transformed middle handbag shell 1, is cut off by tundish impact area involucrum steel plate, makes caisson 3 device of 850 millimeters × 850 millimeters × 200 millimeters of 40 millimeters of steel plates.First first piece high aluminium-magnesia carbon brick 4 being placed in caisson 3 before knotting tundish permanent layer 2, again second piece high aluminium-magnesia carbon brick 4 being built in the dope layer of tundish impact area when building tundish paint layer 5 processed.When molten steel casting, high-temperature molten steel directly impacts at high aluminium-magnesia carbon brick 4, because high aluminium-magnesia carbon brick 4 has the performance of good high temperature resistant, resistant to corrosion and resistance to erosion, so pouring box integral service life can be improved, stop to occur that the accident that tundish worn by molten steel occurs.
