In combination with the newest refractory high-flow casting and casting technology, the surface air porosity of the pre-casting brick surface of the pizza furnace is solved, and the surface air porosity less than 1%。. plus using a gradient cooling technology to solve the problems of the original design insulation layer thickness and the construction inconvenience, adopts the Nanometer level heat insulation & reflection technology, reduces the heat dissipation, the temperature of the kiln is 500 degrees, the temperature of the kiln skin is below 30 degrees, and is developed through eight months, according to the European Union food safety standard, The whole pre-casting high-efficiency energy-saving and heat-preservation pizza furnace is Stereotyped production, which is also the second food-grade industrial refractory project after the first project of laoganma furnace refractory project .
