摘要

Ti-Nb微合金高强度钢板的生产流程为206 t顶底复吹转炉-LF-RH-230 mm铸坯-连轧成3~7mm板工艺。将原0.045Nb-0.015Ti微合金化钢优化成0.070Ti-0.015Nb微合金化钢后

其焊接性能和低温冲击性能优良

并具有良好的综合力学性能。使用结果表明

0.070Ti-0.015Nb微合金化钢与0.045Nb-0.015Ti微合金钢相同

满足加工和服役要求

但成本有明显降低。

Abstract

The production flowsheet for Ti-Nb Microalloy high strength steel plate is 206 t top and bottom combined blown converter-LF-RH-230 mm slab casting-rolling 3 〜7 mm plate process. Through optimizing the original 0.45 Nh- 0. 015Ti microalloy steel to 0. 070Ti-0. 015Nb microalloy steel has excellent welding and low temperature impact toughness properties and has better comprehensive mechanical properties. Service results show that the 0. 07Ti-0. 015Nb microalloy steel is identical to 0. 045Nb-0. 015Ti microalloy steel

satisfactory to requirement of process and service

while the production cost decreases obviously.
