All of fused cast azs block 33#,36# and 41# as refractory bricks have the common properties of dense structure, withstanding high temperature, low pollution to glass liquid, high corrosion resistance to glass liquid, and specific chemical composition. However, as the different content of zirconia, fused cast AZS block 33#, 36# and 41# can be used in different part of glass furnace.

Fused cast AZS block 33#: It has the good casting property which shows that it can be made many kinds of formats and shapes. Fused cast AZS block 33# is mainly used in relatively low temperature and corrosive parts of glass furnace such as working ends, feeder channel, etc.

Fused cast AZS block 36#: It has lower casting property compared to fused cast azs block 33#, so fused cast AZS block 36# is only available for straight brick and it is recommended to be used in sections where corrosion and temperature is higher, such as sidewall, paving, doghouse, etc.

Fused cast AZS block 41#: This block is available in a large size straight or approximates block and special formats and shapes for glass furnace. Fused cast AZS block 41# is especially applied to seriously corrosive parts of glass furnace such as throat, bottom budding, dam block, electric block corners, doghouse and also can be used in sidewalls
