Description

A kind of ignition furnace furnace lining
Technical field
The utility model is mainly concerned with the sintering process apparatus field, refers in particular to a kind of ignition furnace furnace lining.
Background technology
In modern times in the sintering process process; Ignition furnace is used to mix surface hot strip flame is provided; Make solid fuel wherein fire burns; And making top layer compound sintering under ignition furnace high-temperature flue gas and solid fuel ignition exothermic effects, the heat that provides sufficient oxygen amount that the top layer is put aside through the air exhauster exhausting simultaneously is passed to down one deck compound, thereby impels down the solid fuel of one deck to burn away to make sintering process to carry out rapidly downwards and then accomplish sintering process.
In ignition furnace construction and installation process, building by laying bricks or stones of refractory lining is the most complicated, also is the most key link.Through building refractory material by laying bricks or stones, can form the ignition furnace furnace lining structure that has heat insulation, insulation, retaining fire, strengthens sintering effect in steel structure frame inside.When building by laying bricks or stones, to select different anti-materials for use and build means by laying bricks or stones according to the different working condition.According to operating temperature, the temperature stress of body of heater, bear the characteristics that factors such as loading, mechanical damage and chemical erosion take into full account masonry work, the correct selection.Just can make ignition furnace obtain high yield, high-quality, low consumed effect aborning.This shows that furnace lining structure is the core of whole ignition furnace structure, the construction method of furnace lining directly influences the service life of ignition furnace, also affects the ignition furnace construction speed simultaneously, and even influences the maintenance downtime of whole sintering machine.
The furnace lining structure of ignition furnace is divided into three parts: side wall is built by laying bricks or stones, beam is built by laying bricks or stones and furnace roof.
Traditional ignition furnace furnace lining has two kinds of construction masonry methods: integrated poured method and integral prefabricated method.
Integrated poured method: like Fig. 1, Fig. 2 and shown in Figure 3, all the ignition furnace furnace lining forms by the amorphous refractory cast-in-site.When construction, a good template is poured the anti-material of the indefinite form that stirs in proportion wherein into and rapping earlier, and maintenance afterwards 24 to 48 hours after material feeding to be poured has certain intensity, can the demoulding get into next step construction stage.Like Fig. 1, shown in 3, existing beam 9 and existing furnace roof 10 all have part to ride on the existing side wall 11 along the left and right end portions perpendicular to the chassis traffic direction, and existing furnace roof 10 has part to ride on the existing beam 9 in the end, front and back along the chassis traffic direction.This structure can prolong the life-span of furnace lining through the mode that makes existing side wall 11 and existing beam 9 loads.---beam---furnace roof---furnace lining baking that because the restriction of this structure, integrated poured method sequence of construction must be side wall.The furnace lining overall performance of constructing out through integrated poured method is good, and intensity is higher, can guarantee long service life.
Integral prefabricated method: like Fig. 4, Fig. 5 and shown in Figure 6, all the ignition furnace furnace lining constitutes by prefabricated refractory brick body.When construction, only need be fixed in refractory precast block in the ignition furnace steel structure frame with the mode of hanging through existing suspension ring 12 provided thereon and get final product.Be provided with open slot between preformed bricks and the preformed bricks, after installing preformed bricks, need in groove, to pour into a mould amorphous refractory, to strengthen the furnace lining sealing property.Whole building process need not toast and can put into production, and the construction of side wall, beam and furnace roof three phases can interlock and carry out, the regulation order.It is tighter to be well suited for some duration, the engineering higher to schedule requirement.
All there is its shortcoming in these two kinds of building methods of integrated poured method and integral prefabricated method:
One, integrated poured method: because the reason of furnace lining structure, the method need be in strict accordance with side wall the sequence of construction construction of---beam---furnace roof.And generally speaking side wall approximately needs time of 72h from formwork to the cured form removal, and beam approximately needs the time of 72h from formwork to the cured form removal, and furnace roof approximately needs the time of 96h from formwork to the cured form removal, add up to about 240h (10 days) duration.Add the installation of steel construction and space gas pipeline, whole ignition furnace installation period was above 16 days.Even if 24h uninterruptedly constructs, also need about 9 days.And repair envelope time weak point owing to blast furnace in the steel plant; The off-time of whole piece ironmaking production line is often less than a week; The owner will not be for an ignition furnace smelts iron the production line production time with whole piece and delays so long, so integrated poured method often can not be adopted by the owner.
Two, integral prefabricated method: compare the construction period of the integral prefabricated method much shorter that then seems with integrated poured method.Because furnace lining is made up of the fireproof prefabricated brick of plural piece, on-the-spot needs hoisted in position, thus its easy construction, short construction period, whole ignition furnace installation period can guarantee in 6 days.But because preformed bricks is impaired in transportation and installation process easily; Generally there is not service life the integrated casting type structure long, and preformed bricks Chang Yinqi making error, can not closely link to each other during installation; Thereby cause bad coal gas and the naked light of emitting of furnace roof part globality, security performance is lower.The part preformed bricks is because weight is excessive, to hang screw rod too much, and requires every screw rod stressed evenly when hanging, thus to the construction technology level requirement of unit in charge of construction also than higher.
In sum, the formed furnace lining good integrity of integrated poured method, lining durability is long, but construction period is long.And the formed furnace lining short construction period of integral prefabricated method, but globality and service life all not as integrated poured method, and the site operation difficulty is higher.This shows that all there is technological deficiency in these two kinds of furnace lining structures.
