馬弗爐產品介紹

      馬(ma)(ma)弗(fu)爐(lu)(lu)(Muffle furnace)，Muffle是包裹的意(yi)思，furnace是爐(lu)(lu)子(zi)，熔(rong)爐(lu)(lu)的意(yi)思。馬(ma)(ma)弗(fu)爐(lu)(lu)在中國(guo)的通(tong)用叫法有以(yi)下幾種(zhong):電(dian)爐(lu)(lu)、電(dian)阻爐(lu)(lu)、茂福爐(lu)(lu)、馬(ma)(ma)福爐(lu)(lu)。馬(ma)(ma)弗(fu)爐(lu)(lu)是一種(zhong)通(tong)用的加熱設備，依(yi)據外觀形狀可分為箱式爐(lu)(lu)、管式爐(lu)(lu)、坩堝爐(lu)(lu)。

馬弗爐原理
