| Abstract: | Using the thermal simulation technique,the simulated HAZ continuous cooling transformation curves of a fire-resistant steel were drawn. The carbon equivalent has calculated.The crackproof temperature and the maximum HAZ hardness of 25mm plate have forecasted.The results suggested that the steel has low weld cold crack sensitivity. |
