Not having an insulated roof area will certaimly increase your annual heating costs due to excessive heat losses.

但没有保温层的屋顶会因为额外热量的流失，而增加每年的供热成本。

Causes include heating too quickly in the feed zone, melting too slowly in the transition zone, insufficient mixing, and excessive heat loss in the adapters or die.

其原因包括在喂料区加热时间太短和在过渡区熔融太慢、混合不良、在机筒和口模中存在过多的热量损失。

Its characteristic is, fast heating speed, and overheat protection, avoid excessive current damage caused by burn machine, safe and convenient installation.

其特点是，加热速度快，并有过热保护，避免电流过大烧坏机器造成损，安全且安装方便。

In this process, excessive energy consumption, slab's low heating quality and difficulties of optimizing this production process are pivotal problems.

在此过程中存在着生产能耗过大、钢坯加热质量不高、生产过程难以优化等问题。
