Description
Technical field
The utility model belongs to the oven field of accessories, specifically is a kind of walking beam type heating stove water cooling tube stapling structure.
Background technique
Water cooling tube at the bottom of the oven is one of important structure of oven, and it is not only bearing the total weight of blank in the stove, and undertaker's material step-by-step movement important task of advancing, so the heat insulation wrapping of water cooling tube just seems particularly important.For intensity under the anti-sealing deck-molding temperature reduces and distortion, the general high speed cold water process that adopts, the heat that water is taken away is a useless heat loss, account for 15%～30% of oven heat total losses, also can below steel billet, produce " black seal " simultaneously, worsen the heating condition of blank, prolong heating time, produced and added thermal defect, reduced heating quality.Floor tube is to work under big temperature gradient changes, and bear the rapid change of cold and hot furnace temperature, the vibration of material base etc., and this has just proposed very high requirement to the refractory material of wrapping water pipe.
Floor tube wrapping mainly experienced 1, linerless in structure; The integrated poured wrapping of 2 gravity flow pouring materials; Three kinds of structural types of the compound wrapping of 3 gravity flow pouring materials (or tapetum fibrosum) and ceramic fiber blanket.
(1) structure in linerless: adopt the no insulating structure of high speed water cooling, the heat that water is taken away is higher, also can produce serious " black printing " simultaneously below steel billet, the present water beam that has not adopted this kind structure.
(2) integrated poured wrapping: on-the-spot formwork, adopt gravity flow pouring material cast wrapping.This structural entity good airproof performance, technology is simple, and adaptability is strong, and construction cost is cheap; Anti-slag corrosion is relative with structure breakaway ability strong, and wear-resisting, compressive strength and weather-proof ability are more intense, use wider at home.But adopt traditional pouring material structural thermal insulation, a large amount of accessory parts such as anchoring piece must be arranged, this brings very big trouble for maintenance from now on; Conventional construction wrapping maintenance duration is long, and pouring material structure thermal conductivity is big, and is difficult for realizing compound wrapping, so radiation loss causes the waste on the energy still than higher; Secondly, the volume density of pouring material is big, and the bearing load after the insulation of whole piece water pipe is bigger, to the maintenance of water pipe, install and bring very big inconvenience; At last, the stress rupture that full pouring material structural thermal insulation layer internal-external temperature difference produces is serious, and the surface easily produces hot soarfing and splits.No matter be on structure, on insulation, using effect, still all be difficult to get a desired effect from working life.
(3) compound wrapping: be sinter molding prefabricated component and thermal-protective coating, on the steel column that is welded on water pipe, couple together with water pipe, this method structure is more reasonable, but because anchoring piece and interblock slit, cause the insulating structure life-span general, insulation effect is general, fails to play the effect that reduces the water pipe thermal loss significantly.
In recent years, along with the improvement of water cooling tube insulating structure, wrapper material has also experienced several stages: heavy refractory material, lightweight refractory and clay are in conjunction with pouring material.The heavy refractory material mostly is high alumina matter, low cement series, have high temperature resistant, the low performance of shrinkage under the anti-high-strength and high temperature, but its average thermal conductivity is very high, anti-thermal shock and mechanical shock are poor; Light heat-insulating material mostly is light-weight brick grain pouring material, porous clinker pouring material and high-strength ceramic granule lightening casting material etc., and insulation effect is good, but serviceability temperature is low, and intensity is little; Clay is the atypic refractory material of using early in conjunction with pouring material, and intensity is lower under the high temperature.Be subjected to the weak effect and the short limitation of life-span of prefabricated block or pouring material structure in the traditional insulating structure of water cooling tube, cause people progressively to increase in the research experience in this field, simultaneously along with fast development, the innovation of thermal insulating material in recent years, schedule has been mentioned in the improvement of water cooling tube insulating structure again, and becomes one of important subject of national metallurgy industry.
The model utility content

For achieving the above object, the utility model is achieved through the following technical solutions:
It is a kind of walking beam type heating stove water cooling tube stapling structure, comprise walking beam type heating stove water cooling tube assembly and the outside thermal-protective coating that coats thereof, the present technique main points are that thermal-protective coating adopts the ceramic fibre material layer, the ceramic fibre material layer is banded in the water cooling tube module outer surface by the refractory metal silk, lays the cured coating layer at the ceramic fibre material laminar surface simultaneously.
Described water cooling tube assembly is the water cooling tube of Strip casting material thermal insulation layer, and the ceramic fibre material layer is coated on the outside of pouring material thermal insulation layer.
For the ease of construction and raising sealing, the ceramic fibre material layer adopts from-inner-to-outer layering coating successively, and applies resistant to elevated temperatures inorganic binder layer between adjacent each layer.
After the utility model improved prior art, because 1 structure is taked the ceramic fiber wrapping, special anchoring piece was fixed (not needing welding), the top layer protection; 2 ceramic fibers are not corroded by weak acid, alkali and water, oil, steam, do not soak into lead, aluminium, copper, have avoided the destruction of crackle, thermal shock and mechanical shock; 3 structure density only are 150Kg/m
3About, lighter more than 50% than lightweight heat-proof prefabricated block furnace lining, lighter more than 70% than lightening casting material furnace lining, the hot load-bearing that has alleviated boiler tube is loaded; 4 thermal capacity and thermal conductivity are low, and heat loss is few, have strengthened heat insulation effect, have reduced the soft water consumption, have prolonged the water pipe physical life; 5 have reduced fuel consumption, have improved the thermal efficiency of stove, have improved the uniformity of steel billet heating, have improved steel product quality; 6 long service life: original structure is repaiied general March one, adopts this programme, extends to 1～2 year working life; In sum, the utlity model has novel structure; Stable performance; Volume density is light; The advantage of high insulating effect.
