RH炉
真空条件下的二次冶金
西马克集团的 RH 工艺在全球拥有 180 多套设备，处理能力最大可达 400 吨，其特点是脱碳和脱气效果非常好，温度损失相对较低。它特别适用于周期时间较短的熔炼工艺。
RH 工艺不需要特殊的除渣措施、额外的钢包净空或钢包底部的透气砖。快速的炉体更换和高效的钢包运输模式提高了设备的产能，而使用双工位则可进一步提高产能。
RH 工艺具有以下特点：
- 脱碳至最低碳含量
- 快速脱氢
- 合金化精度高，收得率高
- 快速加入大量合金
- 即使添加大量合金，钢包内的钢液也能快速均匀化
- 真空脱碳脱氧处理时间极短
- 温度损失相对较低（取决于批量大小）

Vacuum tank decarburization
Secondary metallurgy under vacuum conditions
The VOD process (Vacuum Oxygen Decarburization) from SMS group has been successfully used in the production and refining of stainless and acid- and heat-resistant steel since the end of the 1950s. To date, more than 100 plants with heat sizes of up to 200 tons have been built using this process. It is used to achieve particularly low carbon contents in an economical way, as the oxidation of chromium is significantly reduced by blowing oxygen for decarburization under reduced pressure. The consumption of reducing agents is also considerably lower.
A VOD plant can be used in a duplex line (EAF – deslagging – (LF) – VOD) immediately after the melting unit or coupled with an AOD converter in a triplex line (EAF – AOD – (deslagging) – VOD). Especially for the production of stainless steels with the lowest carbon contents, such as superferritic steel grades, the VOD process is without alternative.
Our VOD plants are designed to meet the specific requirements of the production program, the timing in the steel mill, and the individual process of our customers. Each VOD plant can also be used as a VD or VD-OB plant.
