Abstract
The utility model relates to a high-pressure resistant heat insulation board provided with metal fire-resisting columns. The high-pressure resistant heat insulation board is formed by a heat insulation board body, the fire-resisting columns and an outer-layer composite membrane. Through holes are uniformly formed in the heat insulation board body at intervals. The fire-resisting columns are respectively tightly embedded in the through holes. The heat insulation board body provided with the fire-resisting columns in a uniformly embedded mode is covered by the outer-layer composite membrane. The high-pressure resistant heat insulation board is characterized in that the fire-resisting columns are metal solid columns or metal hollow columns. Through adoption of the metal solid columns or the metal hollow columns and adoption of the method that the metal hollow columns are filled with refractory matters, the high-pressure resistant and heat resistant characteristics of the refractory matters and the non-embrittlement characteristics of the metal columns are effectively utilized, and consequently the high-pressure resistant heat insulation board provided with the metal fire-resisting columns can be applied to high-temperature occasions and occasions where pressure is exerted repeatedly, and is favorable for improving high-pressure resistant performance of traditional materials.

Background technique
Existing heat insulation compressive strength as glass wool, rock wool, ceramic fiber and nanometer level microporous thermal-protective material itself is little, during for the bigger compressive strength of some application requirements, converter and rotary kiln thermal-protective coating such as steel-making, can adopt energy-saving anti-high pressure thermal baffle (claimant's patent (CN201779405U)), in this kind patent thermal-protective material resistant to elevated temperatures ceramics pole is arranged, can bear the effect of High Temperature High Pressure.But in actual use, some equipment can use this structure such as the ladle bottom of steel-making, and the converter of steel-making and rotary kiln are because rotation frequently, make ceramics pole material in the heat insulation felt of anti-high pressure be subjected to repeatedly squeezing action easily and cracked, such result makes thermal-protective material compressed, and effect of heat insulation descends even influences the safe handling of equipment.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of the existing anti-high pressure thermal baffle of ceramics pole, a kind of anti-high pressure thermal baffle that the metal Fire resisting column is installed is provided, the Fire resisting column that this thermal baffle is installed is metal solid post or metal hollow post, and in the metal hollow post filling fire resisting material, not only overcome the brittle cracking of single ceramics pole, improved the intensity of Fire resisting column, the working life of also having improved Fire resisting column simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of anti-high pressure thermal baffle that the metal Fire resisting column is installed, constituted by thermal baffle, Fire resisting column and outer composite membrane, uniform interval is shaped on through hole on thermal baffle, equal tight setting-in one Fire resisting column in each through hole, heat insulating board at uniform setting-in Fire resisting column is coated with outer composite membrane, it is characterized in that: described Fire resisting column is metal solid post or metal hollow post.
And, be filled with refractory material in the described metal hollow post.
And the refractory material of filling in the described metal hollow post is that oxidation is siliceous, aluminosilicate property, zirconium silicate matter, zirconium oxide matter, carbonization are siliceous, silicon nitride, mullite or aluminum oxide.
And the profile of described Fire resisting column is cylindrical, rectangle or triangle.
Advantage of the present utility model and good effect are:
1, the Fire resisting column of this thermal baffle adopts the mode of filling fire resisting material in metal solid post, metal hollow post and the metal hollow post, can effectively utilize the anti-high pressure high-temperature stability of refractory material and the not embrittlement characteristic of metal column, the occasion that is applied to high temperature and exerts pressure repeatedly is conducive to improve the anti-high-voltage performance of traditional material.
2, the metal column raw material sources that adopt of this thermal baffle are extensive, lower cost for material, and production method is simple, all adopts existing industry equipment and production technology, does not need special production equipment, effectively saves into the product cost.
3, filling fire resisting material mode in the metal hollow post of this thermal baffle employing, not only drawn the advantage of the high temperature resistant anti-high pressure of single ceramics pole, the metal hollow post has been brought into play the good characteristic of cold draw simultaneously, overcome the fragility of single ceramics pole, all be greatly improved in compressive strength and fragility, have good heat-insulation effect, tensile strength height, make characteristics such as simple, application prospect is boundless.
