Product Description

AZS bricks, also known as electrofused AZS refractories, are named after their three primary oxide components in order of concentration – Alumina (Al2O3), Zirconia (ZrO2), and Silica (SiO2). The abbreviations A, Z, and S are taken from the first letters.

The numbers denote the percentages of Zirconia and Alumina. For example: AZS-33 refers to 33% ZrO2 electrofused refractory AZS-36 denotes 36% ZrO2 electrofused brick AZS-41 indicates 41% ZrO2 electrofused lining material

Hongtai Refractory Bricks Fire Resistant Fused AZS33 Bricks For Glass Kiln

Fused AZS33 Bricks are white solids formed by pouring pure alumina powder and zircon sand containing about 65% zirconium oxide and 34% silicon dioxide into a mold and cooling it in an electric furnace. The mixture is poured into an electric furnace for high-temperature electric melting to form a solid blank. The electric melting furnace usually inserts two electrodes into the furnace body at the same time, generates high temperature through the electric arc in the furnace, heats the raw materials to a molten state, and forms a hard blank after melting.

Raw Material of AZS Brick

AZS refractories are categorized by zirconia content into 33, 36, and 41 grades Key raw materials for quality electrofused AZS
bricks include: High purity alumina (Al2O3 > 98.5%) Zircon sand (ZrO2 > 65.6%) Desiliconized zircon (ZrO2 > 85%) Soda ash (Na2CO3
≥ 99%) Boron sand (B2O3 ≥ 37%) Rare earth oxides (Y2O3 ≥ 45%)

Process And Technical

Manufacturer Process of AZS Refractory Brick

1.Raw Materials Preparation: High purity raw materials like alumina, zirconia, silica and binders are weighed and mixed in proper proportions. 2.Forming: The powder mix is formed into desired shapes (usually bricks) by methods like uniaxial or isostatic pressing. 3.Drying: The shaped bricks are dried initially at 110-120°C to remove moisture. 4.Firing: The dried bricks are fired at high temperatures ranging from 1600-1750°C to sinter them. This results in densification and development of desired properties. 5.Cooling: The fired bricks are cooled slowly to room temperature to prevent development of cracks. 6.Finishing: The cooled bricks may be machined to specified dimensions and finishes if required. 7.Quality Checks: The finished AZS bricks are checked for properties like density, strength, microstructure etc.

Melting Technical Requirements

1.Using the long arc melting process and the secondary voltage is controlled between 320-380. Using high-voltage melting in the initial stage of melting, 380V for secondary voltage , controlling 320V as secondary voltage during the refining, the arc length must reach 50-60mm. 2.Current selection: At the initial stage of melting, keeping the current between 3500-4000 Ann, and pay attention to the three-phase electrode current Situation at any time, try to maintain the balance, If using strong current for refining, the current control at 4500 Ann. 3.Oxygen blowing: oxygen is injected step by step, oxygen is blown twice per furnace and the pressure keep 1.4-1.6 megapascals, when the oxygen is blown oxygen lance should be inserted into 1/2 of material liquid depth, and shake slowly to make Oxidation more sufficient. 4.Melting time: Melting time for per furnace is about 150 minutes, 120 minutes for melting and 30 minutes for refining. 5.Casting temperature is 1850-1950°C, winter must be above 1950°.

Casting Processes for Electrofused AZS Bricks

Casting Processes for Electrofused AZS Bricks Conventional Casting – Uses risers and pours directly into molds, resulting in normal shrinkage cavities, typically used on furnace tops. Tilted Casting – Employs angled (30-35°) pouring to concentrate shrinkage to one end, leaving the other extremely dense. Common for pool walls. Near Non-shrinkage Casting – Vertical casting into oversized molds, then removing the top shrinkage section after annealing, creating high density. Also utilized for walls. Non-shrinkage Casting – Similar to near non-shrinkage technique but eliminates all shrinkage cavities. Used for walls and superstructure parts like throats. Key advantages of directional solidification via tilted casting are minimized voids and maximized corrosion resistance. Near non-shrinkage and non-shrinkage processes further enhance density and durability through optimized mold design and post-casting machining.

Application

$Glass Industry Refractory Bricks 3 Tons Capacity For Temperature Furnace Construction$

The difference and application of Fused cast AZS33 Brick

The dense microstructure of AZS33 zirconium corundum bricks makes the bricks have good resistance to glass liquid corrosion, and it is not easy to produce stones or other defects in the glass furnace. It is the most widely used product in glass kilns, and is mainly used for the upper structure of the melting pool, the pool wall and paving bricks of the working pool, and the material channel.

AZS33 is the most widely used product in the cast AZS series, and has excellent performance in preventing contamination of glass liquid. It is widely used in the wall, bottom, upper structure and feeding channel of the glass furnace.
