Abstract
The invention provides a kind of electric and thermal insulating composite material for industry frequency furnace, it does not contain asbestos, is a laminal composite that is bonded together and is formed by several layer materials.Only this composite vertically need be put in the stove during laying and get final product.This material property satisfies the requirement of main frequency furnace thermal insulating, has eliminated harmful pollution of asbestos, owing to only need lay layer of material when repairing stove, 3～4 times have been shortened when repairing furnaceman, having improved labor productivity, alleviated labour intensity, is the novel preferred material of main frequency furnace thermal insulating.
Description
The invention belongs to the insulating heat insulating material technical field, be particularly suited for the main frequency furnace thermal insulating.
Main frequency furnace induction coil internal circular surfaces is lined with the thermal insulating layer, existing main frequency furnace thermal insulating layer is formed through paved in multi-layers by asbestos, glass wool cloth, micarex, common form is to spread one deck glass wool cloth earlier near circle in the induction coil, spread the thick micarex of two-layer 0.5mm then, repave two layers of asbestos board that 3～5mm is thick, spread one deck glass wool cloth or asbestos cloth at last.This thermal insulating layer contains asbestos material, and asbestos are carcinogens, contaminated environment, and need paved in multi-layers when repairing stove, and repair furnaceman's duration, labour intensity is big.
The invention provides a kind of electric and thermal insulating composite material for industry frequency furnace, it does not contain asbestos, and will need the material of paved in multi-layers to be replaced by one deck composite originally.
This thermal insulating composite material is the board-like material that is formed by micarex, alumina silicate felt and glass wool cloth bonding.The alumina silicate felt is a kind of novel insulating refractory, and its heat-proof quality, insulating properties and fire resistance all are better than asbestos, and has eliminated the environmental pollution that asbestos caused.
The concrete technology that realizes electric and thermal insulating composite material for industry frequency furnace of the present invention is on alkali glass silk cloth, do the binding agent thick first class natural mica sheet of 0.1mm that successively bonds with organic silicon insulating varnish, thick until 0.5～1.0mm, this thickness is decided according to the furnace capacity size, and then be stained with one deck alkali glass silk cloth, at last be stained with the thick alumina silicate felt of one deck 5～10mm again, this thickness is decided according to furnace capacity.Bonding finishes, and uses the forcing press compacting, uses steam drying then 6～8 hours, and the drying oven hearth temperature is 100～150 ℃, can use after the cooling of coming out of the stove.
In the thermal insulating composite material, alumina silicate felt and mica layer thickness are decided according to the main frequency furnace capacity.If the main frequency furnace capacity is 3 tons, then alumina silicate felt thickness is 5mm, and mica layer thickness is 0.7mm, can reach main frequency furnace thermal insulating performance requirement.Choose size corresponding insulation heat-preserving complex material (lamellar) according to furnace capacity during laying, vertically be put in the stove, close induction coil compresses and gets final product, at the junction of sheet and sheet overlap joint 100-150mm.
Big and the 1.5 ten thousand volts/millimeter of thermal insulating composite material dielectric strength of the present invention, big and the 0.06 kilocalorie/Mi Shidu of thermal conductivity factor, satisfy main frequency furnace thermal insulating performance requirement, improved work situation, exempt harmful the pollution, owing to only need lay layer of material when repairing stove, improved labor productivity, alleviated labour intensity.
Claims (2)
1, a kind of electric and thermal insulating composite material for industry frequency furnace is characterized in that alumina silicate felt thickness is 5～10mm, and mica layer thickness is 0.5～1.0mm.
2, according to claims 1 described electric and thermal insulating composite material for industry frequency furnace, it is characterized in that layers of material bonding finishes after, with steam drying 6-8 hour, the drying oven hearth temperature was 100～150 ℃.
