提高碳钢强度的级别可以减少低合金钢的产量,因此节省了合金元素,首先是锰,因为许多低合金钢的锰含量都较高。为了研究控制轧制和快速冷却制度对大批生产的低碳钢3机械性能的影响,一些冶金工厂进行了试验。如伊里奇亚速钢铁公司宽带钢轧机实现了控制轧制。转炉钢试验板坯在连续式加热炉加热到1150～1250℃。试验表明,3钢的加热温度从1150℃提高到1250℃(见表1),
Increasing the grade of carbon steels reduces the production of low-alloy steels, thus saving alloying elements, first of all manganese, since many low-alloy steels have a high manganese content. In order to study the effect of controlled rolling and rapid cooling regimes on the mechanical properties of mass produced low carbon steel 3, a number of metallurgical plants were tested. For example, the control of the rolling mill is implemented at the wide-angle mill of Illyya Steel. Converter steel test slab in a continuous heating furnace heated to 1150 ~ 1250 ℃. Tests showed that the heating temperature of steel 3 increased from 1150 ℃ to 1250 ℃ (see Table 1)
