Description
Technical field
The utility model relates generally to the roasting apparatus such as metallurgy, chemical industry, building materials, relates in particular to a kind of rotary kiln preformed bricks.
Background technology
Rotary kiln refers to rotary calcining kiln (being commonly called as rotary kiln), by the difference of material handling, can be divided into cement kiln, chemical metallurgy kiln and limekiln.Cement kiln is mainly used in calcination of cement clinker, is divided into dry production cement kiln and the large class of wet production cement kiln two.Chemical metallurgy kiln is mainly used in the poor iron ore magnetic roasting of metallurgy industry steel plant; Chromium, josephinite oxidizing roasting; Refractory factory roasting high-aluminium vanadine Kuang He aluminium manufacturer roasting grog, aluminium hydroxide; The class mineral such as chemical plant roasting chrome ore and chromite ore fine.Active lime and light dolomite that limekiln (being active lime kiln) is used for roasting steel plant, ferroalloy works.In steel industry now, day by day universal along with the decline of sintering process and acid pellet and direct-reduction pelletizing process, rotary kiln has become a member very important in steel sheet production line.Generally, rotary kiln consists of kiln shell, furnace lining, drive unit three-major-items.Wherein furnace lining is a core component of rotary kiln, and the quality of furnace lining structure can directly have influence on effect of heat insulation, the production thermal efficiency and the service life of rotary kiln.Metallurgical industry is at present to be mixed and build by laying bricks or stones with cast-in-place material by fire-resisting prefabricated brick with the furnace lining masonry way of rotary kiln, and wherein fire-resisting prefabricated brick accounts for more than 80%, can say that the performance quality of preformed bricks has directly determined that the performance of furnace lining is fine or not.A complete rotary kiln is divided into thermal insulation layer two parts under brick body self and brick by preformed bricks, brick body self directly contacts with high-temperature material with furnace high-temperature flue gas, therefore need to possess extremely strong high temperature abrasion resistance, high temperature crushing resistance, high-temperature corrosion-resistance and refractoriness, industrial general employing is allocated the mullite heavy castable of steel fibre into as its construction material.Under brick, thermal insulation layer does not directly contact with inner flue gas of the stove material, but it plays the interior heat transmission toward kiln shell of minimizing stove, reduces kiln shell surface temperature, reduces the meaningless effects such as thermal loss, therefore this layer material need to possess heat-proof quality preferably, less thermal conductivity factor and larger thermal resistance value, industrial general employing expanded perlite matter heat insulation fiber felt is as its construction material.
Refractory brick of the prior art, as shown in Figure 1, brick body is rectangle structure, refractory brick body 1, pilot trench 11, female groove 12, consists of with feet 2.The main part that refractory brick body 1 is preformed bricks, at its forward and backward pilot trench 11 and female groove 12 of offering respectively, when construction rotary kiln furnace lining, the pilot trench 11 of preformed bricks is closely connected with female groove 12 of last adjacent preformed bricks, female groove 12 of preformed bricks is closely connected with the pilot trench 11 of an adjacent rear preformed bricks, can reach so all linked with one another, strengthen the effect of preformed bricks stability.In the bottom of refractory brick body 1, be provided with feet 2, preformed bricks relies on it to be fixed on rotary kiln kiln shell 3.General preformed bricks is established two feet 2(as shown in Figure 2), two feets 2 are divided into 1 square area 4 and 2 rectangular region 5 by filling layer under brick.When construction filling layer, workman need cut into perlite fibrofelt first fiber block 6 corresponding with square area 4, rectangular region 5 sizes and the second fiber block 7(as shown in Figure 3,4), then make it bottom-up preformed bricks upset, the fiber block cutting is filled in to corresponding region at the bottom of brick, and then preformed bricks upset is arranged on kiln shell 3, adopt this installation method, the second fiber block 7 of rectangular region 5 very easily drops owing to not being subject to the extruding restraining force on both sides, meaningless increase duplication of labour number of times and have potential safety hazard.Or workman also can adopt first and preformed bricks is arranged on kiln shell 3; and then fill in the fibrofelt method of (as shown in Figure 5) from preformed bricks side; but because the flexibility of fibrofelt and the reason of cambered surface kiln shell 3 can cause fibrofelt to clog smoothly to design attitude, on-the-spot often meeting cause construction period to extend because of the repeating construction of filling fibrofelt and labour intensity increases.
