slab billet的意思|示意

In this stage semifinished products with smaller cross sections are produced, such as slab, bloom or billet, which are suitable for further rolling.

这个阶段的产品是横断面较小的半成品，如板坯、大钢坯、小方坯等。这些半成品适合于进一步轧制。

The process of heat transfer while slab and billet solidifies is very complicated, but it become easy to describe by equivalent heat transfer coefficient.

连铸坯凝固时的传热过程是一个十分复杂的过程，用等效传热系数的方法来描述则简便易行。

The new technologies of heating steel slab billet using natural gas as fuel and regenerative combustion way are mainly described, as well as obvious energy saving results are gained.

着重叙述了用天然气作燃料，采用蓄热式燃烧方式加热钢板坯的新技术，以及加热炉取得了显著节能效果。
