为了减少氧气放散和确保在事故状态下供氧,齐齐哈尔钢厂曾于1978年委托武汉钢铁设计院设计、十三冶施工,用15锰钒容钢建造了三台120 m~3的贮氧球罐。可是有关资料规定,该钢种在—20℃以下不能使用,所以建成后就被“判死刑”。有关部门曾提出几种挽救方案,都因技术不过关或经济上不合算而未能实现。齐钢对此提出疑议,并作了一些研究工作。在获得有关资料后,向有关单位提出在—20℃以下进行使用试验的咨询。经低温冲击试验证明,该钢种球罐能满足《钢制石油
In order to reduce the release of oxygen and ensure oxygen supply in the event of an accident, Qiqihar Steel Works commissioned the Design Institute of Wuhan Iron and Steel Institute in 1978 and constructed the 13th Metallurgical Works. Three 120m ~ 3 oxygen storage balls tank. However, relevant information stipulates that the steel can not be used below -20 ℃, so it was sentenced to death after construction. The relevant departments have proposed several kinds of rescue plans, which have not been realized because of technology or economic inefficiency. Qi Steel raised the issue and made some research work. After obtaining the relevant information, it will advise the relevant units about the use test below -20 ℃. The low temperature impact test proved that the steel spherical tank to meet the "steel oil
