Description
Technical field
The utility model relates to the grating device that a kind of field of metallurgy hotblast stove or roasting kiln are used.
Background technology
The grating structure that most big-and-middle-sized blast funnace hot blast stoves the most often use at present is a kind of grating device of plain base band crossbeam, this structure is the cross beam support that the grating bottom is used groined type to arrange, each grating all is fixed on crossbeam, under crossbeam, shore supports is arranged; The grating eyelet of this structure has different shape, is mainly petal, circular, square (rectangle, rhombus).This grating device is all generally that checker brick are laid immediately on grating, in addition, a kind of improved device is also arranged, increase exactly a kind of and transition grate piece checker brick one spline structure, at first this transition grate piece is laid on grating, and then checker brick are laid on to (Wang Yingkui on transition grate piece, the design (J) of the movable circular hole grating of No. 3 blast funnace hot blast stoves of Hunan steel, " ironmaking ", 1994, (5), 51-52).
This grating device technique comparative maturity, its advantage is that the grating manufacture is simple, checker brick are laid convenient.
A kind of grating device (patent No. CN2066863U) approaching with the utility model arranged, cancelled crossbeam, and a kind of grating with stiffening web and pillar (accompanying drawing 1) have been used, grating is added to stiffening web replaces crossbeam, stiffening web is made regular hexagon makes it can not stop up the grating eyelet, the monolithic grating directly adopts the pillar independent support adapted with self structure, and the grating bottom matches with the pillar head.Pillar has enough air inlet spaces, ensures that grating and checker brick air-flow are unobstructed.Grating and pillar are 2 absolute construction unit, to increase the heat interchanging area of hotblast stove, improve the heat exchange efficiency of hotblast stove.The advantage of this device is to have cancelled the crossbeam that complex structure, weight are large, stop up the grating eyelet, eliminated the structural stress that crossbeam brings and has been difficult to the defect of eliminating, and increases again the heat interchanging area of hotblast stove, improves the heat exchange efficiency of hotblast stove.
Yet through the long-time running test, the weak point of the first grating device is very obvious: the less stable that at first shows as the grating combination unit, the grating strength decreased of perforation size large (as square, petal etc.), long-time running exists the risk of fracture damage; Complex structure after this grating assembling, be difficult to guarantee enough setting accuracies, and its consequence is that long-time running causes structural stress to be difficult to eliminate; Crossbeam and column have blocked the grating eyelet, and gas flow is produced to larger resistance, have reduced hotblast stove efficiency; Structural stress between the grating be fixed together by crossbeam can be assembled gradually, causes grating device bulk deformation; Its deficiency also shows as, and because potter's clay checker brick chip and dust in hotblast stove cause the smooth spreader plate of small perforations grating device and the blocked possibility of support component eyelet, increases.For the chamber of hot-blast stove checker brick of different perforation sizes, its transition grating structure also needs respective change, thereby has increased manufacture difficulty, also is difficult to carry out standardized designs.
The major defect of the second grating device is to have increased the grating manufacture difficulty, has also increased the weight of monolithic grating.Because, in the grating shape matching complexity near the furnace shell position, its reinforcing rib structure is corresponding complexity also.And this device is not done substantial improvements for the transition grate piece (being spreader plate) above grating.
