Description
Technical field
The invention belongs to technical field of refractory materials, specifically, relate to a kind of low creep flint clay composite refractory brick
And its preparation method and application.
Background technology
In modern carbon element industry, producing anode block with roaster the most universal, the main of carbon baking furnace is appointed
Business is roasting electrolytic aluminum anode carbon block.The baking furnace flame path wall of prior art is built by laying bricks or stones by clay brick and is formed, and fuel is in quirk
Burn, and transferred heat to the anode block closing in hopper by top load andalusite composite fire brick, sun
The roasting in the atmosphere not contacting flame of pole carbon block.So, refractory material in anode-baking furnace except to stand long-term height
Outside temperature, high pressure, still suffering from periodic variations in temperature, therefore, the requirement to refractory material is that high temperature creep rate is low, and loading is soft
Change temperature thermal shock resistance high, reasonable.
And on the market that China is current, although Refractory material for carbon furnace produces the most universal, but, no matter
Be fireclay refractory or high alumina refractories or general creep refractory material all to there is load softening point the highest, hot
The shortcomings such as shake poor stability, long-time use creep rate are big, can cause the appearance deformation that flue wall is too early, damage, anode block
Production is greatly affected.
In order to solve with present on problem, people are seeking a kind of preferably technical solution always.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, thus provide a kind of and there is higher thermal shock resistance, higher
Refractoriness under load and the low creep flint clay composite refractory brick of preferable heat stability.
To achieve these goals, the technical solution adopted in the present invention is: include major ingredient and additive, described major ingredient bag
Include the raw material of following mass percent: flint clay large granule 5%~15%, flint clay bulky grain 15%~35%, little of flint clay
Grain 10%~20%, the little granule of sillimanite 5%~15%, flint clay micropowder 15%~35%, bonding clay fine powder 10%~20%;Described add
Add quality is described major ingredient quality the 4.5%~5.5% of agent.
Based on above-mentioned, described major ingredient includes the raw material of following mass percent: flint clay large granule 5%, flint clay bulky grain
30%, the little granule of flint clay 15%, the little granule of sillimanite 10%, flint clay micropowder 25%, bonding clay fine powder 15%.
Based on above-mentioned, the granularity of described flint clay large granule is 3 mm~4 mm;The oarse-grained granularity of described flint clay
It is 1 mm~3 mm.
Based on above-mentioned, the short grained granularity of described flint clay is less than 1 mm;The short grained granularity of described sillimanite is less than 1
mm。
Based on above-mentioned, the granularity of described flint clay micropowder is less than less than 0.043 mm, the granularity of described bonding clay fine powder
0.074 mm。
Based on above-mentioned, described additive is pulp-water.
Wherein, described major ingredient includes aggregate and fines, and described low creep flint clay composite refractory brick is with the burnt treasured in raw material
Stone large granule, flint clay bulky grain, the little granule of flint clay, the little granule of sillimanite are aggregate, with flint clay micropowder, bonding clay
Fine powder is fines, is mixed by described additive.
The present invention also provides for the preparation method of a kind of described low creep flint clay composite refractory brick, comprises the following steps:
(1) calculate according to above-mentioned mass percent, by flint clay large granule, flint clay bulky grain, the little granule of flint clay, silicon line
The little granule of stone and additive carry out mixed grind and prepare prefabricated pug;Then in described prefabricated pug, add flint clay micropowder, combination
Well as clay fines also carries out mixed grind and prepares mixed grind pug;
(2) described mixed grind pug is pressed into adobe, prepares described low creep flint clay after the calcining of described adobe drying and be combined
Refractory brick.
Based on above-mentioned, described step (2) including: described step (2) including: described mixed grind pug is pressed into adobe, will
Described adobe is dried 24 hours~36 hours under the conditions of temperature is 60 DEG C~130 DEG C;Then by dried described brick
Base carries out calcining 10 hours~24 hours at a temperature of 1450 DEG C~1480 DEG C, thus prepares described low creep flint clay and be combined
Refractory brick.
