fire refractory stone for bakery oven pizza oven and wood stove oven
fire refractory stone for bakery oven pizza oven and wood stove oven
1.Description
Fire clay refractory stone is made from flint clay clinker and binder,through high temperature sintering. Al2O3 content is 30%-48%, SiO2 content is 50%-65%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1750°C, refractoriness under load is 1250-1450 °C, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.

1.Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packing shipment
2.Quality Control
a.According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
1.On wooden pallets with plastic cover:Wooden pallet size:930*930mm load weight of each pallet:1.5-2.0 tons 2.According to customer's demands
