Abstract

The utility model relates to a novel ladle-building brick cup, which consists of two argon-blowing permeable brick cups and a pocket block; wherein, the argon-blowing permeable brick cups and the pocket block are respectively masoned on ladle bottom bricks; the two argon-blowing permeable brick cups are parallel to each other and are staggered from each other; and the pocket block is parallel to the argon-blowing permeable brick cups. The structure design of the novel ladle-building brick cup is reasonable, the phenomenon of ladle bottom expansion is effectively avoided, the breakout accident rate is reduced, and thereby, the stable and smooth production is guaranteed.

Description

The novel liquid steel jar is built brick cup by laying bricks or stones

Technical field

The utility model has related to a kind of novel liquid steel jar and has built brick cup by laying bricks or stones, belongs to field of iron and steel smelting.

Background technology

The molten steel jar is the large-scale instrument of STEELMAKING PRODUCTION indispensability, guarantees molten steel jar service life and safety, to reducing refractory consumption rate, reduce worker's labour intensity, guaranteeing that STEELMAKING PRODUCTION safety, direct motion play important effect.

The capacity of molten steel jar is bigger, in order to guarantee steel-making and refining quality, at the ventilative brick cup of two Argons of molten steel pot bottom design and a pocket block.Present building method, two blocks of ventilative brick cups of Argon are arranged on same the straight line, between them apart from 400mm, and brick is of a size of 300 * 160 * 100mm at the bottom of the molten steel jar jar, the brick-building art of brick is divided into and crouch builds and two kinds of laids on end at the bottom of the molten steel jar jar, when carrying out laid on end, the distance of 400mm is laid on end four row's end bricks just in time.When the molten steel jar is built by laying bricks or stones when toasting (temperature reaches more than 1000 ℃) after finishing, brick at the bottom of four row's laids on end, clay is met thermal expansion in ventilative brick cup of two Argons and the brickwork joint, (the square brick material is a pink fused alumina owing to above-mentioned material coefficient of expansion difference, jar end brick material is a magnalium carbon, clay is a high alumina), expansive force upwards bulges the ventilative brick cup of two Argons and four row's end bricks (above-mentioned situation has all appearred in the molten steel jar of being built before not improving after baking) about 10-15mm along same direction, the slit appears at the bottom of making molten steel jar jar, simultaneously, during converter tapping, molten steel shock point (promptly meeting the steel face) position is just around two blocks of ventilative square bricks, therefore easily produce bleed-out hidden danger at the expansion joint (E.J.) position, cause major industrial accident.

Summary of the invention

The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, and the not expansive novel liquid steel jar that is heated is built brick cup by laying bricks or stones.

In order to address the above problem, the utility model by the following technical solutions:

A kind of novel liquid steel jar is built brick cup by laying bricks or stones, comprise the ventilative brick cup of two Argons and a pocket block, ventilative brick cup of Argon and pocket block are built by laying bricks or stones respectively on brick at the bottom of the molten steel jar jar, and two blocks of ventilative brick cups of Argon are parallel to each other and stagger mutually, and pocket block and the Argon brick cup of breathing freely is parallel to each other.Breathe freely brick cup, pocket block of described Argon becomes 45-60 ° of angle with molten metal ladle trunnion.

Compared with prior art, the beneficial effects of the utility model are: spend around the hour hands rotation 45 of wherein being in a good mood on the former basis that reaches pocket block of breathing freely, rotating the ventilative brick cup relative position of back two Argons staggers mutually, two blocks of ventilative brick cups of Argon and jar expansive force that end brick produces are decomposed along all directions after the pre-thermal expansion, and the direction of expansive force is not on same straight line, avoided because of different brick cups that cause of the material coefficient of expansion and jar situation that end brick upwards bulges, reduced the bleed-out accident rate, prolong the service life of molten steel jar, reduced the production cost of enterprise.

The specific embodiment

A kind of novel liquid steel jar is built brick cup by laying bricks or stones, as shown in Figure 1, comprise the ventilative brick cup 1 of two Argons and a pocket block 2, ventilative brick cup 1 of Argon and pocket block 2 are built by laying bricks or stones respectively on brick at the bottom of the molten steel jar jar, the utility model structural design is rotated the 45-60 degree around the hour hands of wherein being in a good mood on the former basis that reaches pocket block 2 of breathing freely, rotating ventilative brick cup 1 relative position of back two Argons staggers mutually, brick at the bottom of not having between two blocks of ventilative brick cups 1 of Argons simultaneously jar, pocket block 2 is parallel to each other with the ventilative brick cup 1 of Argon, two blocks of ventilative brick cups 1 of Argon and jar expansive force that end brick produces are decomposed along all directions after the pre-thermal expansion, and the direction of expansive force is not on same straight line, can not cause because of different brick cups that cause of the material coefficient of expansion and jar situation that end brick upwards bulges, prolong the service life of molten steel jar, guaranteed the safety and stability direct motion of producing.

Claims

1, a kind of novel liquid steel jar is built brick cup by laying bricks or stones, comprise a ventilative brick cup (1) of two Argons and a pocket block (2), breathe freely brick cup (1) and pocket block (2) of Argon built by laying bricks or stones respectively on brick at the bottom of the molten steel jar jar, it is characterized in that, the ventilative brick cup (1) of two Argons is parallel to each other and staggers mutually, and pocket block (2) is parallel to each other with the ventilative brick cup (1) of Argon.
