Wholesale Fire Clay Bricks With High Refractoriness Refractory Bricks SK34 230*114*65mm For High Temperature Industrial

Product Overview

Refractory fire bricks are specialized products manufactured through a precise process involving chamotte or bauxite blended with binding clay. These bricks feature alumina (Al₂O₃) content ranging from 30% to 90%, directly influencing their refractoriness—the ability to withstand high temperatures without softening or deforming—typically between 1580°C and 1850°C.

The manufacturing includes crushing, batching, mixing, high-pressure molding, drying, and high-temperature sintering in tunnel or shuttle kilns, resulting in superior structural integrity, mechanical strength, and thermal stability. They are classified as medium to high-temperature materials with three grades based on alumina content: low-alumina (30%-48%), medium-alumina (48%-60%), and high-alumina (60%-90%).

Leadsun produces a comprehensive range of fire clay bricks with 30-65% alumina content, all exhibiting excellent strength. For more demanding environments, we offer a hand-fired "super duty" fire clay brick with exceptional mechanical strength.

Key properties include high refractoriness, excellent thermal shock resistance, strong resistance to chemical attack from slags and gases, and reliable dimensional stability at elevated temperatures. These characteristics make them ideal for lining various high-temperature industrial furnaces and kilns, providing essential thermal protection and extending equipment service life.

Frequently Asked Questions

Q1: How do I select the right insulation grade for my furnace?

Selection depends on the maximum operating temperature, thermal cycling frequency, and chemical atmosphere. Please provide your design specifications for a tailored recommendation.

Q2: Do these materials contain hazardous substances?

We offer a range of bio-soluble (low-bio-persistence) fibers that meet international health and safety standards for handling and usage.

Q3: Can you provide customized shapes?

Yes, we provide vacuum-formed custom shapes, blocks, and modules based on your CAD drawings to ensure a perfect fit for your equipment.
