Description
Technical field
The utility model relates to a kind of high temperature furnace top board.
Background technology
Ceramic fibre is a kind of fibrous light refractory material, have in light weight, high temperature resistant, Heat stability is good, thermal conductivity is low, specific heat is little and advantage such as anti-mechanical shock, thereby all obtained using widely in industries such as machinery, metallurgy, chemical industry, oil, pottery, glass, electronics. in recent years because the rising steadily of global energy price, obtained more muching wider application than energy-conservation 10～30% the ceramic fibre of reaching of traditional anti-materials such as insulating brick and pouring material.
With the high temperature furnace that the aluminosilicate refractory fiber plate is made, be to utilize electric current to make heating or heat medium heating in the stove, thereby to the industrial furnace of workpiece or material heating.High temperature furnace is used for drying of heating before the metal forging, metal heat treatmet heating, soldering, powder metallurgy sintered, glass ceramics roasting and annealing, low-melting-point metal fusing, sand mold and paint film etc. in mechanical industry.High temperature furnace is compared with flame furnace, have simple in structure, furnace temperature evenly, be convenient to advantages such as control, good, the no flue dust of heating quality, noiseless.
High temperature furnace is thermal source with the electricity, by heating electric energy is converted into heat energy, in stove metal is heated.High temperature furnace and flame furnace ratio, thermal efficiency height can reach 50～80%, and thermal regulation is controlled easily, and working condition is good, and converter life is long, is applicable to the heating of the workpiece that requirement is tighter, but power consumption expense height.
The high temperature furnace of industrial usefulness generally is made up of with machinery and electric control system etc. heating, alumina silicate fibre insulation material, metal shell, fire door, stove.Heating power is from one kilowatt to thousands of kilowatts of less thaies, and operating temperature below 650 ℃ is being a low temperature oven; 650～1000 ℃ is moderate oven; Be high temperature furnace more than 1000 ℃, in high temperature and moderate oven, mainly heat with radiation mode.
With operating temperature is that high temperature furnace more than 1500 ℃ explains, high temperature furnace has comprised high-temperature ceramic fibre material and electrical heating elements, electrical heating elements has very high hear resistance and elevated temperature strength, very low temperature-coefficient of electrical resistance and good chemical stability, material commonly used have metal and nonmetal two big classes.The metal electric heating element material has nichrome, Cr-Al alloy, tungsten, molybdenum, tantalum etc., is made generally in helix, wavy line, waveform band and corrugated sheet.The non-metal electric heating element material has carborundum, molybdenum disilicide, graphite and carbon etc., is made generally in shapes such as rod, pipe, plate, band.The distribution of heating and CONFIG require and decide according to stove watt level and furnace temperature.
Heat with electrical heating elements, generally need be in the roof of the furnace perforate, if make roof of the furnace with a monoblock high temperature ceramic fiberboard material, and the needed hole of processing heating element heater, roof of the furnace is through using several times, and the top can crack, and uses the alumina silicate fibre at top to drop for a long time, cause whole roof of the furnace to subside, cause serious consequence.
In order to overcome the above problems, top material adopts the pyroceram fibre plate, arrangement according to fiber, adopt the method for vertical setting of types, splicing with one one on top board, the ceramic rod furred ceiling is used in the centre, prevents to subside, and burner hearth is heated to uniform temperature, high temperature ceramic fiberboard heat also can occur and rise, top board is cracked, subside easily, if adopt splicing, itself just there is the gap between one one, tension force can discharge to gap location when heat rose, and the power that bear at the top is also relative obtains discharging the service life and the serviceability that can prolong high temperature furnace.
Summary of the invention
The utility model provides a kind of high temperature furnace top board, solves the high temperature furnace inside dimension and causes the problem of subsiding greatly, effectively suppresses the top board fracture phenomenon that top electrical heating elements perforate is caused.
The purpose of this utility model is achieved through the following technical solutions:
The high temperature furnace top board, it is characterized in that: comprise several piece aluminosilicate fiberboard and ceramic rod, all have the hole on the every aluminosilicate fiberboard, the position in hole is identical with size on every aluminosilicate fiberboard, several piece aluminosilicate fiberboard vertical setting of types is stacked, and the hole that ceramic rod passes on the aluminosilicate fiberboard is serially connected with one with the several piece aluminosilicate fiberboard.
Above-mentioned high temperature furnace top board, the length of described aluminosilicate fiberboard are 1000mm, and width is 600mm, and thickness is 50mm.
The utility model has the advantages that:
The utility model stove roof plate can use for a long time in temperature more than 1500 ℃, its heat insulation effect is very good, and longer service life makes the design of furnace roof portion more reasonable, thoroughly solve the stove inside dimension and cause the problem of subsiding greatly, effectively suppress the top board fracture phenomenon that top electrical heating elements perforate is caused.
Description of drawings
Fig. 1: the schematic diagram of aluminosilicate fiberboard stacked state.
The implication of each Reference numeral:
The 1-aluminosilicate fiberboard; The 2-hole.
The specific embodiment
As shown in Figure 1, the high temperature furnace top board, comprise several piece aluminosilicate fiberboard 1 and ceramic rod, all have hole 2 on the every aluminosilicate fiberboard 1, the position in hole is identical with size on every aluminosilicate fiberboard, several piece aluminosilicate fiberboard 1 vertical setting of types is stacked, and the hole that ceramic rod passes on the aluminosilicate fiberboard is serially connected with one with the several piece aluminosilicate fiberboard.Wherein, the length of every aluminosilicate fiberboard is 1000mm, and width is 600mm, and thickness is 50mm.
The quantity of aluminosilicate fiberboard 1 is decided according to the size of high temperature furnace, have hole 2 (size in hole is determined according to used ceramic rod specification) on the aluminosilicate fiberboard 1, the position size in hole is consistent on every aluminosilicate fiberboard, the porose maintenance of aluminosilicate fiberboard vertical setting of types splicing time institute is concentric, by ceramic rod aluminosilicate fiberboard is stringed together, the top board that assurance is spliced into does not subside, and increases the service life.According to the size and the quantity of heating element heater, on the good top board of splicing, open the hole that heating is installed, because of the burner hearth top board for being spliced, the slight crack that perforate caused significantly reduces.
