Abstract
The utility model relates to a heat insulating plate, in particular to a glass fabric cloth-metal foil composite reflective heat insulating plate comprising a substrate layer (1). A plurality of slurry layers (2) and metal foil layers (3) are combined on the substrate layer (1) in an intersected manner, the substrate layer (1) is made of glass fabric cloth, and the metal foil layers (3) are made of aluminum foil. The glass fabric cloth-metal foil composite reflective heat insulating plate comprises the substrate layer which is made of the glass fabric cloth, and provided with the plurality of slurry layers and the metal foil layers in a combined and intersected manner, the slurry layers are formed by mixing water-based glue, silicon dioxide powder and mineral wool, the structure is compact, and air in gaps can not flow easily, so that heat convection possibility is reduced; and the sectional areas and the contact areas of particles on the slurry layers are small, so that the coefficient of heat conductivity is smaller; in addition, as the metal foil layers made of aluminum foil are arranged between the slurry layers, the heat insulating plate has extremely high reflectivity, and can effectively block the penetration of heat radiation.
Description
Technical field
The utility model relates to a kind of thermal shield, specifically relates to a kind of glass cloth metal foil complex reflex thermal shield, is mainly used in industries such as iron and steel, non-ferrous metal, pottery, kiln, electric power, traffic, cryogenic engineering and chemical industry, belongs to the thermal-protective material technical field.
Background technique
In Iron And Steel Industry, ladle belongs to the container of metal smelting liquid, heat-energy losses factor more complicated.Along with the development of steel-smelting technology, ladle no longer has been a simple liquid metal carrying container in recent years.The molten steel time is longer because the appearance of external refining and continuous casting technology, ladle are loaded, and ladleful constantly enlarges, and this has just proposed further requirement to thermal-protective material.Traditional thermal-protective material structure is the big particle aggregate, because structural porosity, the amount of flow that is easy to generate thermoconvection is big; Because the section area of contact of particle is big, so thermal conductivity is also bigger; And because infrared rays is transparent, so thermal radiation penetrates easily.This will cause the molten steel heat-energy losses very big; Temperature drop speeds up, and occurs Low temperature steel easily, carries out smoothly in order to guarantee continuous casting production; Must adopt and improve tapping temperature or compensate through the refining temperature raising, this just certainly will cause the lot of consumption of the prolongation duration of heat and the energy, raw material; The ladle skin temperature is too high in addition, and involucrum intensity and croop property reduce, and causes ladle shortening in working life.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Provide that a kind of structure is tight, thermal conductivity is little and can stop the glass cloth metal foil complex reflex thermal shield that thermal radiation penetrates; It can effectively reduce the ladle thermal loss; Reduce the energy, consumption of raw materials, improved the quality of strand and the working life of ladle.
The purpose of the utility model is achieved in that a kind of glass cloth metal foil complex reflex thermal shield; Be characterized in: it comprises substrate layer; Be compounded with some powder slurry layers and metal foil layer on the said substrate layer; Said some powder slurry layers and metal foil layer interlaced arrangement, said substrate layer adopts glass fiber cloth to process, and said metal foil layer adopts aluminium foil to process.
Compared with prior art, the beneficial effect of the utility model is:
A kind of glass cloth of the utility model metal foil complex reflex thermal shield; It comprises the substrate layer that glass fiber cloth is processed, and is compounded with some powder slurry layers and metal foil layer on the substrate layer, said powder slurry layer and metal foil layer interlaced arrangement; Powder slurry layer is mixed by water-based glue, SiO 2 powder and mineral wool; Its structure is tight, and air pole is difficult in the space flows, so its thermoconvection is less; And because the basal area and the area of contact of powder slurry layer particle are little, so its thermal conductivity is also less; In addition owing to be provided with the metal foil layer of processing by aluminium foil between powder slurry layer and the powder slurry layer; Have very high reflectivity, can stop effectively that thermal radiation penetrates, therefore effectively reduced the ladle thermal loss; Can guarantee that continuous casting production carries out smoothly; Help improving slab quality, reduced the loss of the energy, raw material, and working life of having improved ladle.
Description of drawings
Fig. 1 is a kind of structural representation of glass cloth metal foil complex reflex thermal shield.
Wherein:
Embodiment
Referring to Fig. 1, the utility model relates to a kind of glass cloth metal foil complex reflex thermal shield, and it comprises substrate layer 1, staggered some powder slurry layers 2 and the metal foil layer 3 of being compounded with on the said substrate layer 1.
Said substrate layer 1 adopts glass fiber cloth to process, and said powder slurry layer 2 adopts water-based glue, SiO 2 powder and mineral wool to mix, and said metal foil layer 3 adopts aluminium foil to process.
When glass cloth metal foil complex reflex thermal shield is produced; At first at the glass fiber cloth surface brush last layer powder slurry of ground, bonding one deck aluminium foil on the powder slurry treats that powder slurry layer solidifies the back and brushes one deck powder slurry again at aluminium foil surface then; Powder is starched surperficial bonding one deck aluminium foil, so repeats repeatedly.The powder slurry is determined by the concrete working environment of client that with the number of plies of aluminium foil the powder slurry also can be adjusted with aluminum foil thickness.When product uses, only need to brush one deck glue in substrate layer 1 bottom, can glass cloth metal foil complex reflex thermal shield be adhered to ladle inner wall then, it is extremely convenient to use.
