Description
Technical field
The present invention relates to a kind of saggar and production method thereof, the saggar of producing with the inventive method is applicable to production sponge iron, reduction ferrotianium, powder metallurgy etc.The invention belongs to refractory materials and production method technical field thereof.
Background technology
Chinese patent discloses " a kind of composition of raw materials of producing saggar ", and (publication number: CN1240775A), the optimum formula of above-mentioned patent application is: A stone flour 5%, flint clay 10%, purple female joint 35%, Inner Mongol soil 5%, fossil meal 15%, living stone flour 10%, silica glass 20%.Its making method is that elder generation distinguishes 7 kinds of raw materials by hard material, soft clay, respectively hard material is carried out artificial pick → washing → stone and grind pulverizing; Soft clay is carried out artificial pick → ball mill dry powder → dry → be ground into particle, then the hard material that crushes and soft clay are mixed in proportion the water that batching adds 10%-13% and stir, both can be used for making the saggar product.The kiln-firing temperature is 1350 ℃.
Saggar with aforesaid method production is applicable to that ceramic industry uses, and its main drawback is as follows: (1) above-mentioned saggar product can not be used to produce sponge iron, reduction ferrotianium, powder metallurgy etc.(2) because more expensive its production cost that makes of flint clay price is higher.(3) because silica glass content is higher, saggar is easily split.(4) owing to give birth to the adding of stone flour, the ventilation property of saggar is improved, can influence the quality of sponge iron, reduction ferrotianium.
Summary of the invention
Technical problem to be solved by this invention provides a kind of long service life, is difficult for splitting, cost is low, manufacture craft is simple, is applicable to saggar and production method thereof that metallurgy industry uses.
The technical solution adopted for the present invention to solve the technical problems:
One, saggar:
Saggar of the present invention is formed through pulverizing, batching, stirring, water logging bubble, pug mill pugging, moulding, drying, kiln-firing by the raw material of following weight parts:
(1) wrought aluminium aluminite: 18-30
(2) aluminium aluminite: 11-24
(3) purple female joint: 3-16
(4) clay: 3-10
(5) talcum powder: 3-10
(6) silica glass: 1-3.
Two, the production method of saggar:
(1) press the requirement of row weight part and take by weighing each raw material:
A. wrought aluminium aluminite: 18-30
B. aluminium aluminite: 11-24
C. purple female joint: 3-16
D. clay: 3-10
E. talcum powder: 3-10
F. silica glass: 1-3;
(2) pulverize:
A. aluminium aluminite is ground into the particle that particle diameter is 0-3mm with hammer mill;
B. female joint of purple and clay are crossed the 100-200 mesh sieve respectively behind selection by winnowing mill or Raymond mill mill;
(3) batching, stirring:
Above-mentioned each material is put into drum mixer by ratio requirement to stir;
(4) water logging bubble:
The above-mentioned material that stirs was steeped 12-30 hour through water logging;
(5) pug mill pugging;
Material after soaking is practiced 2-3 time through pug mill;
(6) moulding:
Be processed into the tank body blank with body maker;
(7) drying:
Above-mentioned tank body blank is dry saturating, till promptly being dried to the tank body blank and turning white; Drying means is that fan dries up;
(8) kiln-firing:
The tank body blank kiln-firing that drying is saturating, the kiln temperature is 1200-1250 ℃, the firing time is 46-50 hour;
(9) cooling back kiln discharge.
Method of the present invention can also be set up the glazing operation between above-mentioned (6) step and (7) step, glazing refers to be the glazing of tank body blank outside surface that concrete grammar is as follows:
(1) take by weighing the glazing raw material by following weight part:
A. yellow clay; 15-28
B. clay: 5-12
C. wrought aluminium aluminite: 2-5;
(2) make pasty state after above-mentioned three kinds of raw materials are soaked in water, the viscosity of pasty state refer to finger insert mention after, soak the slurry layer of a bed thickness 0.5-1mm on the finger; Get final product to the tank body blank outside surface cast one deck that is dried to 7-8 one-tenth then; Be dried to 7-8 become to refer to the tank body blank hold in the palm indeformable till; Drying means is that fan dries up.
The source of each raw material and act on as follows:
(1) wrought aluminium aluminite: the place of production is the logical space refractory factory production of Shanxi Province's Yangquan City.
The main effect of wrought aluminium aluminite has been the lean usefulness that turns into, can reduce the plasticity-of sizing, and reduces the tank body blank in shrinkage dry or when burning till, and is simultaneously high temperature resistant.
(2) aluminium aluminite: the place of production is Shanxi Province's Yangquan City and Hebei province's Xingtai City.
The effect of aluminium aluminite has been the aggregate effect, and resistance to elevated temperatures is good.
(3) purple female joint: the place of production is Hebei province's Xingtai City and Shanxi Province's Yangquan City.
The effect of purple female joint is that plasticity-is good, is beneficial to moulding.
(4) clay (being commonly called as blue or green pricker): the place of production is Hebei province's Xingtai City and Shanxi Province's Yangquan City.
The effect of clay is to be beneficial to moulding.
(5) talcum powder: the place of production is Haicheng City, Liaoning Province county.
Talcous effect is that anti-extremely cold and very hot performance is good.
(6) silica glass: the place of production is the Lingshou County, Hebei province.
The effect of silica glass is a shrinking percentage of offsetting clay, makes saggar be difficult for splitting; Heat stability is good.
The glazing places of origin of raw materials and effect:
(1) yellow clay: the place of production is Hebei province's Xingtai City.
The effect of yellow clay is to make the glaze light.
(2) clay (being commonly called as blue or green pricker): the place of production is Hebei province's Xingtai City and Shanxi Province's Yangquan City.
The effect of clay has been bonding and the aggregate effect.
(3) wrought aluminium aluminite: the place of production is the logical space refractory factory of Shanxi Province's Yangquan City.
The effect of wrought aluminium aluminite is to make the adjacent saggar phenomenon that in use do not stick together.
Advantage after the glazing of saggar outside surface is to reduce shrinking percentage, and saggar is firmer, plays protective layer, in use, makes the adjacent saggar phenomenon that do not stick together; Reduce the ventilation property of saggar.
The invention has the beneficial effects as follows long service life, the access times of saggar are 3 times of like product, and access times can reach 10-20 time; Be difficult for splitting; It is over half to use aluminium aluminite can reduce cost than flint clay as aggregate, and manufacture craft is simple.
