Description
1.かさ密度が大きく、重質バーナタイルの重量は270~300kg/セットであり、内張りの荷重圧力を増やし、特に、トップバーン部位のバーナタイルは、非常にアンカー固定され難いため、パレット、支持板、及び保護板を必要とし、18kg/セットであると予測する。
2.重量が高いため、断片化して装着されなければならなくて、吊り掛けの困難さが極めて大きく、少なくとも3人で同時に装着する必要があり、装着空間が狭くて、操作の困難さが極めて大きい。
3.耐熱衝撃性が弱く、バーナーはひび割れやすく、高密度の材料は落ちやすく、人を傷つける恐れがある。
4.熱伝導率が高いため、炉外壁のバーナー部位の温度が高くなる。
