Abstract
The related manufacture method for light insulating refractory brick comprises: mixing 40~70wt% chamotte or 45~75wt% bauxite chamotte or 50~80wt% corundum mullite, 5~30wt% raw clay, 0.5~3wt% polystyrene ball and 5~20wt% organic ablative material as well as 15~25wt% water; putting former mixture into mould 2, compressing with a compression device 1 and vibrating with a vibrating device 4 both with 0.1~3min; taking out for natural dry. This invention has well thermal shock resistance with low coat.
Description
One, technical field
The invention belongs to technical field of refractory materials.Relate in particular to a kind of preparation method of light fire brick.
Two, background technology
Light fire brick is by the gentle phase composite of solid phase, and gas forms isolated pore in the solid brick, and therefore, the thermal conductivity of light fire brick is lower, plays a part heat-insulation and heat-preservation in thermal kiln furnace.And the preparation method of insulating fire brick directly influences the gas phase distribution situation, has determined the performance of insulating fire brick.
At present, the method for producing light fire brick both at home and abroad has:
1, casting.Casting is the mud injection model that will configure, and drying is made adobe.But because of adding moisture content many, green strength is low, the carrying cracky, drying time is long, cuts that to grind clout many;
2, squeeze the mud method.Squeeze the mud method normally with the extrusion molding in vacuumizing mud extruder of prefabricated pug,, be cut into goods brick blank drying.But drying time is long, and it is many to cut the mill clout;
3, machine platen press.The machine platen press is to utilize brick pressing machine that the adobe material is pressed into adobe, and the pore-forming material of machine platen press is generally natural or synthetical contains the hole material, as floats pearl, perlite, vermiculite, silicon bath soil and artificial hollow ball etc.The adding of these aglites, the one, the source is restricted; The 2nd, the brick in-vivo tissue constitutes inhomogeneous, and the matrix part is comparatively fine and close, and brick body thermal conductivity increases; The 3rd, add and to float pearl and then it can be heated to collapse and lose bursting property and be brought in the brick, the thermal shock resistance of floating bead brick is reduced, and thermal shock resistance is a key property of insulating fire brick.
Three, summary of the invention
The purpose of this invention is to provide a kind of raw material sources extensively, need not dry, cut the mill light fire brick that clout is few, thermal shock resistance is good the preparation method
For achieving the above object, the present invention adopts technical scheme to be: will or be the chamotte of 40～70wt% or be the high alumina of 45～75wt% or be that the corundum-mullite of 50～80wt% mixes with the raw clay of 5～30wt%, the polystyrene spheres of 0.5～3wt%, the machine burning lost article that has of 5～20wt%, add the water of 15～25wt%, put into mould after mixing, put down pressurizing device, the Vibration on Start-up device vibrates, pressurization, time of vibration are 0.1～3min, take out seasoning then.
It is described that the machine burning lost article is arranged is the mixture of a kind of in wood chip, rice hulls, the coke powder or two kinds or three kinds; The pressure of pressurizing device is 0.001～0.2Mpa.Vibration processes has constant compression force all the time.
Owing to adopt technique scheme, raw material sources of the present invention are extensive, and because of adding moisture fewly need not dry, owing to once shaped do not have cut the mill clout or cut the mill clout few, the machine burning lost article that has that adds can guarantee even air hole distribution, thereby has the advantages that cost is low, thermal shock resistance is good.
Compare with existing insulating fire brick, the present invention also has the following advantages:
1, thermal conductivity is low, and especially under the condition of high temperature, thermal conductivity is relatively low, and thermal and insulating performance is good;
2, good thermal shock stability, in the use temperature scope, brick is indeformable, does not peel off;
3, according to the purposes difference, select rational physical strength for use, make the every performance the best of light cinder brick;
4, higher refractoriness under load and less reheating linear change rate on reheating are compared with the light fire brick of similar material, and use temperature is higher, and the life-span is longer, and is safer;
5, with short production cycle, production capacity is big, in time meets customer need.
The present invention is when possessing above advantage and characteristics, and its Application Areas is also more extensive.On traditional sense,, also can be directly used in the working lining of multiple industrial furnace such as process furnace, furnace roof as the insulating, can increase substantially the industrial furnace heat insulation effect, reduce energy consumption, reduce the body of heater weight of industrial furnace, change furnace binding, for kiln design provides more selection.
