Abstract
A method for making tin bottom brick, is belongs to fireproof material technology areas. It includes batching, mixing, vibration and compression for molding, conservation and drying, heat treating and rubbing. It is characterized by after the mixed pug are poured into the model, vacuumpumping first then vibration and compression for molding. There are 3%-5%(weight percentages)paper pulp barren liquor in blending. The invention adopts the method of vacuumpumping first and then vibration and compression to solving the problems that the residual air leads to lamination crack when producing thicker brick.
Description
Technical field
The invention belongs to technical field of refractory materials, be specifically related to a kind of method for making of bottom brick of molten tin bath.
Background technology
Molten tin bath is the key equipment of float flat glass production line, and the quality of bottom brick of molten tin bath then is directly connected to the important factor that can molten tin bath normally move and influence the float glass quality.The production method of at present domestic bottom brick of molten tin bath has 4 kinds: 1) vibration cast molding: combination is the combination of aluminous cement normal temperature, production efficiency is higher, its shortcoming is: introduced 1～3% CaO in the middle of composition, product properties is had a negative impact: the brick body becomes fragile, hot strength is low because of the Young's modulus increase makes, poor in molten tin bath high temperature section work reliability, anti-Na
2O aggressiveness variation influences work-ing life; 2) mud cast molding: combination is the clay combination, wet moulding, higher, the anti-Na of hot strength
2The O erosion performance is better, and the quality of goods is better.But production efficiency is low, the production cycle is long, goods easily produce internal fissure, now domestic seldom have in this manner produce; 3) ramming process: combination is the clay combination, semi-dry pressing, and the quality of goods is better, and hot strength is higher, the erosion performance of anti-Na2O is better.But the goods internal structure is difficult for evenly, goods easily produce internal crack.4) isostatic pressing: combination is the clay combination, semi-dry pressing, and the quality of goods is best.Hot strength is higher, the erosion performance of anti-Na2O is better, is the senior goods in the middle of the bottom brick of molten tin bath.But cost of goods manifactured is higher, and price is higher.
Summary of the invention
When the object of the present invention is to provide a kind of method for making of bottom brick of molten tin bath to overcome common vibrating forming machine production than thick product, because of air can not effectively be got rid of, and cause the problem of slabbing, the bottom brick of molten tin bath brick internal structure that adopts the present invention to make is even, zero defect.
The present invention adopts following technical scheme to realize:
A kind of method for making of bottom brick of molten tin bath comprises batching, mixing, vibration extrusion forming, maintenance drying, thermal treatment, attrition process, it is characterized in that mixed pug is gone into mould after, vacuumize earlier and vibrate extrusion forming again.
According to the method for making of bottom brick of molten tin bath of the present invention, it is characterized in that being evacuated to vacuum tightness 〉=0.05Mpa, further be to be evacuated to vacuum tightness 〉=0.09Mpa.Contain weight ratio in the batching and be 3～5% calcium lignosulfonate.
The present invention adopts Al
2O
3-SiO
2Be that raw material is prepared burden, preferred following raw materials by weight percent batching:
Particle diameter is the aggregate 0～15 of 5-3mm
Particle diameter is the aggregate 15～35 of 3-1mm
Particle diameter is the aggregate 25～35 of 1-0mm
Particle diameter is the aggregate fine powder 15～35 of 0.088mm
Bonding clay 10～20
Calcium lignosulfonate 3～5
Aggregate is a kind of of flint clay, Ke More.
All raw materials that the present invention adopts all are commercial goods.
The beneficial effect that the present invention has is:
1) on the basis of using unique high quality raw material, adopt the clay wedding agent, guaranteed that goods have good hot strength and anti-Na
2The O erosion performance;
2) the present invention adopts and to vacuumize the technological method that vibrates pressurization more earlier, has solved when producing than thick product, because of air can not effectively be got rid of, and causes the problem of slabbing;
3) the bottom brick of molten tin bath internal structure that makes of the present invention is even, zero defect; Young's modulus is moderate, brick body good toughness; The hot strength height is applicable to any position of high low temperature of molten tin bath bottom.
4) the present invention reinforced fast, vacuumize fast, pressurization frequency height, pressure is big, the demoulding is fast, the production efficiency height, final product rate height, cost is low.
