We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Brief introduction of mullite insulation brick JM28
Mullite insulation brick JM28 can withstand high temperature of more than 1790℃. Load softening starting temperature 1600-1700℃, room temperature compressive strength 70-260MPa, good thermal shock resistance, high strength, low high temperature creep rate, low expansion coefficient, small heat coefficient, acid slag erosion resistance. And can greatly reduce the weight of high temperature furnace, reform the structure, save materials, save energy, improve production efficiency.
Applications of mullite insulation brick JM28
Mullite light brick JM28 is widely used in residue gasifier, second stage ammonia reformer, carbon black reactor and refractory kiln. Product dimensions, physical and chemical indicators, service life are up to customer requirements.
