Spalling resistant high alumina bricks

Spalling resistant high alumina bricks

Spalling resistant high alumina bricks contain the component that have much smaller expansion coefficient than high-alumina bauxite. The thermal shock stability enhances the high temperature and chemical corrosion resistance.

Composition:Al₂O₃ ≥70%

Bulk Density:≥2.55 g/cm³

Refractoriness:≥1470℃

Available industries:cement, nonferrous and chemical industry

Features: flexibility corrosion high temperature stability enhance

Introduction

☆ Spalling resistant high alumina bricks use high alumina bauxite as the main raw material, introduce a small amount of ZrO₂ (because ZrO₂ is a phase transition between monoclinic and square, which can improve the thermal shock stability of the product), add a certain amount of composite binder and Additives, by controlling the particle gradation of the mud, the refractory bricks made by molding and high-temperature firing become Spalling resistant high alumina bricks. Spalling resistant high alumina bricks have good high temperature resistance and strong corrosion resistance; they have certain mechanical strength, friction resistance and good thermal shock resistance; Spalling resistant high alumina bricks have a long service life.

☆ For serve under severe conditions, spalling resistant high alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag. ZHENJIN REFRACTORIES manufacture and design spalling resistant high alumina bricks to meet the requirements of a great variety of service conditions through quality control.
