Along with improving constantly of permanent layer material class, density of material progressively increases, when being poured into molten steel jar top, because the impact of bottom brick layer vibrating head vibration when being difficult to bear the static pressure of molten steel and cast, the avalanche phenomenon very easily occurs, cause that all that has been achieved is spoiled and the cast failure.For the material for permanent liner in pouring after preventing to toast sticks on the shoe last or hat block tire brick, before the cast need the shoe last or hat block tire brick outer wall that lays with water the material feeding contact site and lay Polypropylence Sheet.Because the permanent liner of cast is thinner, the slit is less, therefore lays difficulty of Polypropylence Sheet, be easy to occur wrinkle, be difficult to Polypropylence Sheet is laid smooth, thereby cause the permanent liner after the cast to produce defectives such as interlayer, pipe, uneven and cast space, the serious cast again of must dismantling.
Summary of the invention
The purpose of this utility model provides a kind of novel shoe last or hat block tire brick, and defectives such as the permanent liner surface interlayer that occurs when fundamentally solving knotting molten steel jar permanent liner, pipe, uneven, cast space prevent shoe last or hat block tire brick avalanche problem in the casting process.For this reason, technical solution adopted in the utility model is:
A kind of molten steel jar shoe last or hat block tire brick is characterized in that shoe last or hat block tire brick front end is shaped as circular-arc protrusion, and the rear end is shaped as circular-arc recessed; The leading flank of brick has arc groove, and trailing flank is provided with at least one boss.
The recessed arc radius in the circular arc that described shoe last or hat block tire brick front end protrudes and rear end is identical.
Upper surface at shoe last or hat block tire brick scribbles barrier coat.Barrier coat can adopt common paint, high temperature resistant paint, graphite and water-repellent paint etc. not with the material of material for permanent liner in pouring generation chemical reaction.
Center of arc's point of shoe last or hat block tire brick leading flank arc groove overlaps with center of arc's point of shoe last or hat block tire brick upper surface arc.
The summit of shoe last or hat block tire brick trailing flank boss and corresponding being on the same cross section of bottom land of leading flank arc groove.
The boss of shoe last or hat block tire brick trailing flank is round, oval platform or bucking ladder.
The width of described arc groove is greater than the maximum gauge or the width 1～3mm of boss.
The enforcement the beneficial effects of the utility model are:
Because the shoe last or hat block tire brick brick shape of the utility model is reasonable in design, simple and practical, therefore in building construction, need only adjacent two shoe last or hat block tire brick tails are joined, the anterior arc that protrudes of the shoe last or hat block tire brick in back just is embedded in the recessed arc in last rear portion just, and can adjust the radian of shoe last or hat block tire brick according to the deformation extent of molten steel ladle bowl, two bricks are fitted together perfectly, can not produce the slit.Between levels, the boss of upper strata shoe last or hat block tire brick lower surface is embedded in the arc groove of lower floor's shoe last or hat block tire brick upper surface just, has avoided in the building process problem of brick fault position up and down; Solved when watering steel the avalanche problem that bottom brick layer occurs simultaneously to molten steel jar top.Substituted Polypropylence Sheet with barrier coat, both played the effect of isolating shoe last or hat block tire brick and material for permanent liner in pouring, the permanent liner of having avoided again causing owing to the Polypropylence Sheet wrinkle produces defectives such as interlayer, pipe, uneven and cast space.
