Abstract
The utility model discloses a chute supporting structure of a sinter cooling furnace, and relates to the field of cooling furnaces. The chute supporting structure of the sinter cooling furnace is composed of a plurality of supports which are evenly distributed in a radial mode. Each support comprises stainless steel and refractory bricks, wherein the refractory bricks are located on the periphery of the stainless steel, and every two adjacent refractory bricks are reinforced through stainless steel fasteners. The upper ends of the supports are fixedly connected with the lower end of an inner ring brick body of the cooling furnace, the lower ends of the supports are fixed on a brick body of a chute area, and meanwhile the brick body of the chute area supports an outer ring brick body of the cooling furnace. The chute supporting structure of the sinter cooling furnace is high in strength, convenient to replace and long in service life.
Description
Technical field
The utility model relates to the cool furnace field, relates in particular to a kind of chute supporting construction of sintering deposit cool furnace.
Background technology
In steel manufacture process, the energy consumption of sintering circuit accounts for 9%~12% of total energy consumption, is only second to Iron-smelting, and sintered, energy saving occupies very consequence in iron and steel enterprise is energy-conservation.Heat sinter sensible heat and sinter fume sensible heat account for more than 40% of sintering process hear rate, the importance that takes full advantage of this part of waste heat and be sintered, energy saving meets the requirement that national energy-saving reduces discharging policy, also meet iron and steel enterprise and reduce cost, improve the needs of enterprise competitiveness.
The main cold machine of ring type or the straight line cooler technology of adopting of present domestic sintering deposit cooling, major way is: cooling-air is blown into sinter cooler by air blast, and heat sinter is cooled to below 150 ℃, and hot-air reclaims through the anterior flue gas cover of cooler.The shortcoming of this mode is: the waste heat parameter fluctuation is large, and the system air leakage problem is difficult to solve.Therefore, change existing hot-air and reclaim technique, solve sintering waste heat and utilize an intrinsic difficult problem, to reducing the sintering process energy consumption, providing iron and steel enterprise's benefit and competitiveness significant.
Adopt the cooling of sintering deposit stove formula can effectively solve above-mentioned technical barrier, and the chute supporting construction of traditional cool furnace vertically is built into by the multiple layer refractory block assembly.Every layer of refractory brick unit comprises a plurality of refractory brick groups of size, form fit.The horizontal close-packed arrays of each refractory brick group, each the refractory brick group refractory brick that is formed in one.Its shortcoming is: the weight of ring masonry is born by refractory brick in the cool furnace, the impact of sintering deposit particle and wash away also and born by refractory brick.The refractory brick brickwork joint is easy to cracking under the impact of thermal stress and sintering deposit particle and souring, this is easy to wearing and tearing refractory brick under the impact of sintering deposit particle and souring.When cracking and wearing and tearing chute supported the weight can't bear ring masonry in the cool furnace, chute supported and interior ring masonry can subside, and causes the cool furnace damage.Again it is large to build chute support and the required workload of interior ring masonry by laying bricks or stones, and required refractory brick and human cost are very high.
The utility model content
The technical problems to be solved in the utility model is: the chute supporting construction in a kind of sintering deposit cool furnace is provided, and its intensity is high, and it is convenient to change, long service life.
To achieve these goals, the technical solution adopted in the utility model is: it is radial equally distributed support and is formed by a plurality of, described support comprises stainless steel and refractory brick, and refractory brick is positioned at the stainless steel periphery, and is reinforced by the stainless steel clamp between adjacent two refractory brick; The support upper end is fixedly connected with the lower end of ring masonry in the cool furnace, and the support lower end is fixed on the chute district masonry, and chute district masonry supports cool furnace outer shroud masonry simultaneously.
Described support is 12 to 30.
The beneficial effect that the utility model brings is:
(1) main body of support is stainless steel Welding Structure (is H shaped steel among the figure, but is not limited to this), and intensity is high, is conducive to the service life that guarantees that chute supports;
(2) stainless steel Welding Structure skin is built refractory brick by laying bricks or stones, and refractory brick reinforced by the stainless steel clamp, born the impact of sintering deposit particle and washed away by refractory brick, and stainless steel Welding Structure itself can not worn and not torn because of washing away of sintering deposit particle;
(3) the stainless steel Welding Structure plays the main support effect, and it is heat-resisting, heat insulation, wear-resisting that refractory brick plays a part.In case refractory brick damages, because refractory brick is on every side supported by stainless steel, so can easily the refractory brick that damages be removed, the refractory brick that more renews has greatly been saved the maintenance time of cool furnace.
(4) even because replacing fire-resistant, wear-resistant castable is untimely, cause the stainless steel Welding Structure partly to damage.The ring masonry also can keep complete in the cool furnace under other intact stent support, can not damage.Only the stainless steel welding support that damages need to be cut off, the upper new stainless steel Welding Structure of welding can be repaired again.

Fig. 2 is the top view of the chute supporting construction in the sintering deposit cool furnace;
Fig. 3 be among Fig. 1 A to the plane of support;
Fig. 4 is the B-B profile of Fig. 3 medium-height trestle.
Among the figure: 1. cool furnace outer shroud masonry; 2. chute district masonry; 3. support; 4. encircle masonry in the cool furnace; 5. castable refractory; 6. stainless steel clamp; 7. refractory brick; 8.H shaped steel.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figures 1 to 4, the chute supporting construction in a kind of sintering deposit cool furnace, it is radial equally distributed support 3 and is formed by a plurality of, and support is preferably 12 to 30.Described support 3 comprises stainless steel and refractory brick 7, and refractory brick 7 is positioned at the stainless steel periphery, and stainless steel adopts H shaped steel 8, and is reinforced by stainless steel clamp 6 between adjacent two refractory brick 7, and the cross section of stainless steel clamp 6 is " recessed " type, and exposed face is laid with castable refractory 5.Support 3 upper ends are fixedly connected with the lower end of ring masonry 4 in the cool furnace, and support 3 lower ends are fixed on the chute district masonry 2, and chute district masonry 2 supports cool furnace outer shroud masonry 1 simultaneously.
