Abstract
A warming furnace hose with a heat-insulating protective layer belongs to a high-temperature resistant rubber hose and particularly relates to a special hose for steel making enterprise moderate furnaces. A rubber tube is wound by steel wires with calibers larger than 152mm, is provided with a composite internal rubber layer and attached with the heat insulating protective layer on the outer rubber surface, thereby forming the hose via integral vulcanization. The moderate furnace hose has the advantages of pressure and high temperature resistance, flexible hose body and significant flexibility. Due to the composite internal rubber layer and the polytetrafluoroethylene heat insulating protective layer added on the outer rubber surface, fire baking resistance and heat radiation of the hose are increased greatly, the hose can work at a medium temperature of 180 DEG C and an environmental temperature of 220 DEG C and has longer service life, low manufacturing cost and small replacement frequency.
Description
Affiliated technical field
The utility model belongs to pressure hose, is particularly related to steel smelting enterprise medium-temp furnace device special hose.
Background technique
In steel smelting enterprise, molten steel need be transported molten steel with ladle after blast furnace process is finished.Ladle is subjected to the influence of ambient temperature and humidity before injecting molten steel, the molten steel temperature difference of its inside temperature and molten state is huge, and has condensed water or water vapor etc. in the ladle.As under this situation, injecting molten steel, can make molten steel splash or explode.Therefore ladle need be placed on the warm stove device its heating and dehumidification before injecting molten steel.And the method for heating and dehumidification is: earlier ladle is inserted in the warm stove device, cover overturn cover, the nozzle through the overturn cover top sprays into the high pressure blast furnace gas and makes blast furnace gas spray combustion in ladle.Overturn cover on the temperature stove device all need be opened upset with the replacing of ladle, and the operation that takes ladle is constantly carried out on warm stove device.This just need have one section high temperature resistant subdues but the flat flexible hose that must not collapse is connected between the outlet of the nozzle on the warm stove device overturn cover and blast furnace gas conveyance conduit.This section flexible hose is referred to as warm stove device flexible pipe.
Warm stove device hose body in China steel smelting enterprise generally adopts corrugated stainless steel tubing at present.Though high temperature resistant, flexible, the flat performance of not collapsing that this bellows has is subdued in frequent wide-angle (90 °～150 °) and just have been become the equipment easily damaged parts under the working state, and cost is higher.Need to stop work, stop to carry out after blast furnace gas, the cooling and change warm stove device flexible pipe, influenced working efficiency, strengthened smelting cost.Owing to the improvement of steel smelting process, medium temperature will reach 180 ℃ again, and ambient temperature can reach more than 200 ℃, also need a kind of alternative flexible pipe satisfy above-mentioned requirements.
Summary of the invention
The purpose of this utility model is: research and develop a kind of exsertile heavy caliber pressure hose of flexible resistance in the strong environment of high-temperature baking thermal radiation that satisfies, to replace stainless steel ripple flexible hose.
The technical solution of the utility model is: the warm stove device flexible pipe of developing a kind of tool refractory protection; it be adopt compound inner glue layer and outside the glue surface paste the heavy caliber steel wire spiral rubber hose of refractory protection, the pipe structure of heavy caliber steel wire spiral rubber hose is followed successively by compound inner glue layer 1, mesoglea 2, strengthening course 3, mesoglea 2, steel wire from inside to outside and twines enhancement layer 4, mesoglea 2, steel wire and twine enhancement layer 4, mesoglea 2, strengthening course 3, outer glue-line 5, refractory protection 6 formations.
Described compound inner glue layer 1 is made up of through gluing being laminated with folder teflon activation film between anti-blast furnace gas, high temperature resistant aging sizing material; Described outer glue surface refractory protection is formed through gluing pasting by teflon activation film.
Compare with existing corrugated stainless steel tubing; the utlity model has withstand voltage high temperature resistant, inboard wall of tube body is smooth, the media flow resistance is little, the exsertile characteristics of body flexible resistance; because flexible pipe has adopted compound inner glue layer to increase the teflon refractory protection again; its flame resistant baking and thermal-radiating performance increase substantially; can make flexible pipe proper functioning under the condition of 200 ℃ of 180 ℃ of medium temperatures and ambient temperatures; further prolong working life, cheap; the replacing frequency reduces, and economic benefit is considerable indirectly.For warm stove device special stainless steel bellows has increased another alternative pressure-resistant rubber flexible pipe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Fig. 2 is the utility model pipe structure partial enlarged drawing.
As shown in the figure, the utility model is made up of compound inner glue layer 1, mesoglea 2, strengthening course 3, steel wire winding enhancement layer 4, outer glue-line 5, refractory protection 6.
Embodiment
Below in conjunction with accompanying drawing mode of execution of the present utility model is described.
Embodiment: outside external diameter is 200mm steel tube core, twine compound inner glue layer 1; then finish the outer glue-line 5-of coating mesoglea 2-strengthening course 3-mesoglea 2-steel wire winding enhancement layer 4-mesoglea 2-steel wire winding enhancement layer 4-mesoglea 2-strengthening course 3-successively and paste the polytetrafluoroethylplastic plastic activation zone; be that refractory protection 6, the last outer water cloth that twines are after integral body sulfuration setting; separate water cloth; depoling, block, finished manufacturing of the present utility model.Steel wire winding working procedure in the manufacture process is finished on special-purpose heavy caliber steel wire Stetch Wrapping Machine.
Compound inner glue layer 1 and 5 layers of used sizing material of outer glue are the medium of anti-blast furnace gas the, high temperature resistant aging special-purpose sizing material.
