铁水包及化铁炉流槽加盖非常可观地降低了热量损失,从而明显节约能量,然而实践中却很少这样做,因不了解其实际的优越性。这样,我们在各方面,如在焦炭、煤气、电、工资、铸件质量和工作条件等方面得支付不加盖的“罚款”。因而盖的安装是必需的,这也不必花多大的费用。为明了其优点,首先让我们看看通过加盖避免了的热损失。 Hot metal ladle and tempering furnace runner stamped very significantly reduce the heat loss, which significantly save energy, but in practice seldom do so, do not understand the actual advantages. In this way, we pay uncapped “fines” in all aspects, such as coke, gas, electricity, wages, casting quality and working conditions. Therefore, the installation of the cover is necessary, which does not have to take much expense. To clarify its merits, let’s first look at the heat loss that is avoided by stamping.
