Product Description

China refractory manufacturer factory supply high alumina checker bricks as heat exchanger in regenerator for coke oven

The High alumina checker bricks produced by our company are based on the production of ordinary clay bricks, using high-quality homogenizing materials as the main raw materials, adding appropriate amounts of auxiliary materials and some additives, after fine grinding, mixing, and high-pressure molding, at an appropriate firing temperature It transforms into mullite crystal phase, and the residual product has a good mineral composition to ensure that the product has high refractoriness, dense bulk density, low porosity, excellent high-temperature creep performance and good volume stability.

The international standard refractory brick code is the model beginning with SK. Among them, the aluminum content of SK-34 corresponds to the domestic content of 48, the SK-36 corresponds to the domestic content of 55, and the content of SK-38 is 75. High alumina bricks are differentiated according to their Al2O3 content. Currently, 48%, 55%, 60%, 65%, 73%, 75%, 80%, etc. are often used.

1.Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
2.Al2O3 content is 48%-80%,main mineral components are corundum and mullite phases.
3.Refractoriness is above 1770°C,refractoriness under load is 1420-1550°C.
4.Working temperature:1350°C -1650°C.
