The specific embodiment
Below, describe exemplary embodiment of the present utility model in detail with reference to accompanying drawing.
Corundum pocket block of the prior art is prefabricated profiled, namely pour into a mould the corundum spinelle castable by mold integral, obtain finally by Overheating Treatment, so its porosity is large, erosion-resisting characteristics and the anti-poor-performing that declines, in tapping process, exist unavoidably the part slag to cause its erosion rate to be accelerated by the pocket block etch mouth of a river, therefore service life is very short, and because it is integral prefabricated moulding, need integral replacing after damage, consumption of materials is large, and cost is higher.
Fig. 1 is the structural representation of upper brick cup of the combined type mouth of a river brick cup of the utility model exemplary embodiment, Fig. 2 is the structural representation of middle brick cup of the combined type mouth of a river brick cup of the utility model exemplary embodiment, Fig. 3 is the structural representation of lower brick cup of the combined type mouth of a river brick cup of the utility model exemplary embodiment, and Fig. 4 is the structural representation of the combined type mouth of a river brick cup of the utility model exemplary embodiment.As shown in Figures 1 to 4, comprise according to the combined type mouth of a river brick cup of the present embodiment upper brick cup 1, middle brick cup 2 and the lower brick cup 3 that combines from top to bottom, the molten steel channel 4 of pocket block 5 runs through brick cup 1, middle brick cup 2 and lower brick cup 3, and upper brick cup 1, middle brick cup 2 and lower brick cup 3 are compressing magnesium carbon brick.At first, because the present embodiment adopts compressing pocket block, therefore can produce respectively brick cup 1, middle brick cup 2 and lower brick cup 3, and its combination is built by laying bricks or stones be pocket block 5, in use can change and reclaim according to the operating position of each brick cup, be conducive to the reduction of cost.Particularly, in pocket block 5 after combination, only have the upper surface of upper brick cup 1 directly to contact with molten steel or slag with inner surface, and middle brick cup 2 only has inner surface directly to contact with molten steel or slag with lower brick cup 3, therefore only need to be when the ladle light maintenance on brick cup carry out rational local replacing and can realize the raising in pocket block life-span and the reduction of consumption, effect is remarkable.
In addition, compressing is to process raw material by equipment such as jaw crusher, ball mills, and then through the hydraulic press mode that raw material is compressing, therefore its porosity is less, and the material of magnesium carbon brick is the magnesium carbonaceous, it has stronger slag resistance, therefore be not easy to be corroded by slag, has obtained further guarantee service life.
According to the structure of upper brick cup 1, middle brick cup 2 and the lower brick cup 3 of the combined type mouth of a river brick cup 5 of the present embodiment as shown in Figure 1 to Figure 3, its concrete size and structure can be carried out specific design according to ladle and Production requirement.For example, in the present embodiment, the height that the height of upper brick cup 1 and middle brick cup 2 is 210mm, lower brick cup 3 is 195mm, the diameter of molten steel channel 4 (being the internal diameter of brick cup 1, middle brick cup 2, lower brick cup 3) is 145～155mm, be preferably 150mm, reduce to some extent than 176.7mm of the prior art, thereby improved the effective thickness of pocket block 5, if the diameter of molten steel channel 4 is too large, service life and poor effect; If the diameter of molten steel channel 4 is too little, can affect self-opening rate.In addition, the molten steel channel in the part molten steel channel in middle brick cup 2 and lower brick cup 3 can also be toroidal, is conducive to like this outflow of molten steel, slag.And, also should be designed with the structure that can mutually make up between upper brick cup 1, middle brick cup 2 and lower brick cup 3, for example can adopt protuberance commonly used in prior art and the positioning combination structure of recess.
Generally speaking, the opening part of the molten iron passage 4 of pocket block 5 is provided with the back draught of certain altitude, so that the inflow of molten steel or slag, in an embodiment of the present utility model, the opening back draught height of the molten steel channel 4 of pocket block is 15～25mm, is preferably 20mm, reduce to some extent than 65mm of the prior art, thereby can improve the resisting longitudinal erosiveness of pocket block, if this opening back draught height is too large, may affect the life-span; If this opening back draught height is too low, may cause drainage effect not good, equally also affect self-opening rate.
At last, the carbon increasing amount of every stove molten steel checks after the brick cup of the combined type of the present utility model mouth of a river to using, and concrete data are as shown in table 1:
Table 1 carburetting computational chart
Illustrate: a cover combined type mouth of a river brick cup nearly weighs 150Kg, rolls off the production line during with residual thick 50mm, consumes altogether gross weight and is about 73Kg; Magnesium carbon brick requires carbon content C 〉=10%, if with 15% calculating, consume altogether 10.95Kg; With 40 calculating in minimum service life, average every stove carburetting 0.27Kg, carburetting 0.00014% is namely about 1.4～2.0ppm, therefore carburetting is vestige.
In sum, adopt the utility model not only can improve the service life of pocket block and guarantee that carburetting is vestige, effectively improved the service life of ladle and the controllable force of refractory material cost, and significantly improved the benefit of steel mill.
Although the above illustrates and has described the utility model in conjunction with the embodiments, but what those skilled in the art will appreciate that is, in the situation that do not break away from the spirit and scope of the present utility model that limit as claims, can make the various changes on form and details here.
