Product Description

0.6-1.0 density light weight mullite insulation brick K23 K26 K28 as ceramic tunnel kiln or ceramic shuttle kiln lining

Light weight Mullite insulation brick is a kind of quality refractory insulation materials for resisting high temperature with
features of light weight, low thermal conductivity, thermal insulation and high compression strength in the high temperature furnaces or kilns. lightweight bricks are mainly used for the top of hot blast stove, stack and bottom of blast furnace, regenerative chamber of glass melting furnace, lining of ceramic high temperature furnace and so on.

Mullite insulation brick is manufactured with mullite as the main crystal phase and contains about 65~75% alumina content. Mullite Insulation Brick has high refractoriness that reaches up to 1790 ℃. Its apparent initial softening temperature is about 1600~1700℃. Its cold crushing strength is about 70~260MPa. Mullite Insulation Brick can be classified into different types of 1350 lightweight brick, 1450 lightweight brick and 1550 lightweight brick according to different service temperature and into Lightweight Mullite Brick and Heavy Mullite Brick according to different bulk density.

Specification

0.6-1.0 density light weight mullite insulation brick K23 K26 K28 as ceramic tunnel kiln or ceramic shuttle kiln lining

Light weight mullite brick Characteristics:

Mullite insulation brick is a kind of quality high temperature materials with the following excellent performance.
Low thermal conductivity and Low heat capacity
High Purity and low impurity content
Excellent high temperature strength
Good thermal shock resistance
Low expansive conductivity
Great resistance to acid and alkali erosion

Lightweight Mullite Insulation Bricks Features:

1. Low thermal conductivity, with good thermal insulation effect; 2. Low thermal melting, due to low thermal conductivity, the mullite series of lightweight insulation bricks accumulate little heat energy, and the energy saving effect is obvious in intermittent operation; 3. Low impurity content has very low iron box alkali metal and other oxide content, therefore, high refractoriness; high aluminum content makes it maintain good performance in a reducing atmosphere; 4. High compressive strength in hot state; 5. Accurate appearance and size, speed up the masonry, reduce the amount of refractory mud, ensure the strength and stability of the masonry, thereby extending the life of the lining; 6. It can be processed into special shapes to reduce the number of bricks and joints. It can be directly used for the lining of high-temperature kilns, and has been widely used in shuttle kilns, roller kilns, glass and petrochemical kilns.

There are many kinds of products standard in different countries, regulars are Chinese standard MG23 (1230°C), MG25(1350°C), MG26(1400°C), MG27(1450°C), MG28(1510°C), MG30(1620°C), MG32 (1730°C); and similar JM23, JM25, JM26, JM27, JM28, JM30, JM32; and K23, K25, K26, K27, K28, K30, K32 and others likes A series, A1, A2, A3, A4, A5, A6, A7; B series, B1, B2, B3, B4, B5, B6, B7; C series, C1, C2, C3 and some refractories have their own name, like MD, HT and so on.

If you don't have detailed information, Just tell us which type of furnace, using temperature and size, we could choose proper refractory products for you. If you could supply more details, like sintered products, whether have atmosphere and what, refractory brick drawings and data sheet, we'll be very appreciated.
