Abstract
The invention relates to a Maerz kiln suspension cylinder liner body. The Maerz kiln suspension cylinder liner body is characterized in that the bottom of a cylinder body is welded with anchor ribs and a clamping groove; one end of a hanging brick is clamped by the clamping groove; a ceramic fiber felt is used as an expansion joint and a heat insulation material to be laid; castable is total mullite castable; the ceramic fiber felt, the clamping groove, the hanging brick and the anchor ribs are sealed in a casting body block; the clamping groove is provided with reinforcing ribs; and the reinforcing ribs are connected with the outer wall of the clamping groove to carry out reinforced supporting on the clamping groove. The Maerz kiln suspension cylinder liner body has the advantages of overcoming the design defects of a conventional Maerz kiln suspension cylinder liner body and meanwhile greatly reducing material cost.
Description
Technical field
The present invention relates to the high-temperature refractory technical field, particularly relates to the suspension cylinder refractory material protection lining body of the Maers Kiln of latest model band suspension cylinder.
Background technology
Maers Kiln suspension cylinder liner body with suspension cylinder is in～1150 ℃ of high-temperature work environments for a long time, the characteristic that must have high temperature high voltage resistant, wear-resistant, resistance to erosion, lining body castable not only requires it to have certain heat-insulating property, and need have enough intensity and hardness, could satisfy at high temperature withstand voltage, wear-resisting, resistance to erosion demand.Foreign side's design and the corundum castable that provides, with regard to the refractory material index, be domestic best, but the heat-insulating property of refractory material and intensity, hardness itself are conflicts and since the end of anchor rib from burner hearth very close to, the thermal conductivity factor of adding corundum castable is larger, austenite matrix occurs and changes in the support frame anchor rib temperature drift that causes corundum castable, and metallographic structure has the hot-spot phenomenon, so that the anchor rib mechanical performance declines to a great extent, finally concentrate the face fracture at stress.
Summary of the invention
Purpose of the present invention just provides a kind of Maers Kiln that solves and hangs the design defect that the cylinder liner body exists, and the Maers Kiln of decrease material cost hangs the cylinder liner body simultaneously.
Solution of the present invention is such:
The present invention includes ceramic fiber blanket, anchor rib, draw-in groove, hanger brick, castable, at suspension cylinder bottom welding anchor rib, draw-in groove, hanger brick one end is fixed in the draw-in groove, ceramic fiber blanket lays as dilatation joint and heat-barrier material, castable is full mullite castable, and described ceramic fiber blanket, anchor rib, draw-in groove, hanger brick are locked in the cast block.
More particular embodiment also comprises: described cylinder base is welded with fixed card slot, and draw-in groove blocks an end of hanger brick, and hanger brick connects castable in cylinder base.
Further: described draw-in groove is provided with reinforcement, and reinforcement is connected with the draw-in groove outer wall, and draw-in groove is strengthened supporting.
Advantage of the present invention is:
(1) hang cylinder liner body castable and adopt full mullite castable, the replace imported corundum castable had both satisfied technological requirement, can reduce again approximately 300,000 yuan of investments;
(2) take hanger brick as main, anchor rib is that auxiliary novel castable hanging structure is that domestic and international similar kiln type is pioneering, and provides practical experience for follow-up design;
(3) because suspension cylinder bottom is provided with draw-in groove and hanger brick, be the precedent of domestic and international similar kiln type to the construction of draw-in groove and castable;
(4) Maers Kiln hangs cylinder liner body Novel pouring material structure through practice, comes off without the suspension cylinder castable, and the working of a furnace is stable.
Description of drawings
Accompanying drawing is embodiments of the invention.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the syndeton schematic diagram of draw-in groove 5 and hanger brick 3.
The specific embodiment
The present embodiment is to connect hanger brick 3 at suspension cylinder cylinder base welding draw-in groove 5, and described castable 4 adopts full mullite castable, and described draw-in groove 5, hanger brick 3, anchor rib 2 are locked in the cast block.
Full mullite castable 4 and anchor rib 2 desired indexs that the present embodiment adopts are as follows:
After the use, not only satisfy technological requirement, also reduced investment.
Because hanger brick 3 usefulness refractory materials form by a firing, can not be out of shape, ftracture so can under higher temperature, use for a long time, common clayey hanger brick serviceability temperature is about 1350 ℃, and High-Alumina hanger brick serviceability temperature can reach more than 1450 ℃.According to lime strong basicity characteristics, this processing scheme adopts the High-Alumina hanger brick.The material of anchor rib 2 is: 1Cr18Ni9Ti.
Described suspension cylinder cylinder base is fixed with draw-in groove 5, and the end that described draw-in groove 5 blocks described hanger brick (3) is connected in cylinder base with hanger brick 3; Described draw-in groove 5 is provided with reinforcement 6, and described reinforcement 6 is connected with draw-in groove 5 outer walls, and draw-in groove 5 is strengthened supporting.
The material of the draw-in groove 5 that the present embodiment adopts is 20
#Boiler steel, although the heat conductivility of full mullite pouring material decreases than the corundum castable of import, but thermal conductivity factor is still larger, if only adopt the fixedly mode of castable of anchor rib, because be difficult to avoid the kiln temperature fluctuation in the production process, the anchor rib temperature still might reach the austenite phase transformation temperature, the draw-in groove mode of connection then not only makes weld seam be strengthened, main is the heat radiation of having strengthened between draw-in groove and suspension cylinder, has guaranteed the mechanical strength of draw-in groove.
