盐亭Ⅰ型预制灶芯是选用普通耐火、保温、坚实、体轻的材料,如炉渣、矿渣水泥、砂为主研制而成的。其中炉渣灼烧后形成气孔,起隔热作用。矿渣水泥耐热性好,砂和炉渣质地坚硬,导热系数小、保温性能好。成型的灶芯,下大上小,成喇叭形,易于产生负压,有利通风,上火快,燃烧比较 Yanting Ⅰ type prefabricated kitchen core is the choice of ordinary fire-resistant, thermal insulation, solid, light materials, such as slag, slag cement, sand-based developed. After the formation of stomatal furnace slag, from the role of insulation. Slag cement heat resistance, hard sand and slag texture, thermal conductivity is small, good thermal insulation properties. Molded core, under the big small, into a trumpet, prone to negative pressure, favorable ventilation, fast fire, combustion comparison
