Description
Technical field
The present invention relates to a kind of ultralight degree insulating fire bricks, belong to technical field of refractory materials.
Background technique
China's economic development is rapid, and the development of production of energy relatively lags behind much.China's economy keeps 9% for a long time
Growth rate, and disposable production of energy amount growth rate is then held only in 4% or so.Solve another method of energy shortage
It is energy conservation, that is, the utilization efficiency for reducing heat loss, improving thermal energy reduces energy waste.Energy conservation project is considered as " in the world
Five energy ", meaning is particularly significant.It is calculated according to national departments concerned, all kinds of kilns in China and heat supply pipeline are due to keeping the temperature not
It is kind, equivalent about 3000~40,000,000 tons of coal of the mark of annual heat loss.It is transformed using novel heat insulation technology and equipment, makes this
A little kilns and heat supply pipeline reduce heat loss 20~30% be it is entirely possible, this will make China saves every year mark coal 600~
8000000 tons.
The accumulation of heat and radiation loss of liner of industry kiln heat-insulating material typically constitute from Industrial Stoves total energy consumption 20~
45%.Traditional industry stove is to achieve the purpose that heat preservation energy-saving, usually in heavy refractory brick marshalling or the unsetting fire proofed wood of heavy
Material construction is external to increase light heat-insulating fire resistant brick.Light heat-insulating fire resistant brick requires light-weight, reheating degree height, intensity height, thermally conductive system
Number is low.Light heat-insulating fire resistant brick can be produced by extrusion forming and mechanical pressing method: extrusion forming is first to obtain size to be greater than
It is required that the strip green body of specification, obtain requiring the product of specification after processing using cutting after firing, efficiency is very low；Mechanical pressing
The product for requiring specification can be directly obtained, production efficiency is greatly improved.Ultralight degree insulating fire brick is bulk density lower than 0.8
g/cm3Insulating fire brick, can only be produced by extrinsion pressing by conventional formulation and technique can just obtain ultralight degree up to standard every
Hot fire resisting brick product, mechanical pressing method is due to pressure limit, obtained ultralight degree fire resisting brick product indices, including reheating
National standard is not achieved in degree, compressive resistance and thermal coefficient.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of ultralight degree insulating fire brick, specific technical solution is:
A kind of ultralight degree insulating fire brick, is made of the raw material of following mass ratio: silicon powder 10-20%, kyanite fine powder
20-30%, glass bead 50-60%, white clay powder 1-5%, yellow starch gum 0.2-2%；
Preparation method includes the following steps:
1) raw material is subjected to ingredient, mixing, wet-mixing in proportion, obtains pug；
2) pug for obtaining step 1) is formed and is dried, and obtains green body；It is described to be shaped to mechanical pressing；
3) green body for obtaining step 2 is fired, and obtains ultralight degree insulating fire brick；
The bulk density of the ultralight degree insulating fire brick is 0.3g/cm3。
Further, it is made of the raw material of following mass ratio: silicon powder 15%, kyanite fine powder 26%, glass bead
56%, white clay powder 2%, yellow starch gum 1%.
Beneficial point of the invention is: ultralight degree insulating refractory of the invention turns by improving to composition of raw materials, can
With using the molding production of machine platen press, relative to traditional processing technology, production efficiency is improved.And ultralight degree of the invention is heat-insulated
Refractory brick reheating degree with higher, compressive resistance and lower thermal coefficient, are better than national standard, and service performance is good.
