Meanwhile, the coated surface was hydrophobic with a contact angle of 107.2°since the introduction of methyl groups and methylene groups. Static immersing corrosion test, potentiodynamically polarization curve and electrochemical impedance spectroscopy were conducted to evaluate the film corrosion performances. The results of potentiodynamically polarization curve and EIS in 55wt% LiBr solutions at room temperature in atmospherical pressure indicated that the corrosion current density of BMBSE film coated surface was 4 orders of magnitude smaller than that of bare SUS304 steel, and the impedance was increased by a factor of 10000. Static immersing corrosion test presented that the BMBSE film can significantly increase the corrosion resistance in 55wt%LiBr solution at 180°C compared with stainless steels.

同时由于有机组分甲基和亚甲基的引入，结构均匀致密，并具有一定的疏水性；电化学测试结果表明BMBSE膜的极化阻抗比不锈钢大4个数量级，自腐蚀电流密度也下降低了4个数量级左右，具有良好的耐腐蚀性能；成膜的影响因素优化结果表明BMBSE、EtOH、D.I.water摩尔比为1∶4∶3，热处理温度为200℃时，更有利于制备结构均匀、致密、耐腐蚀性能好的薄膜；静态浸泡腐蚀实验结果说明，在180℃、55%的高温溴化锂溶液中BMBSE膜能起到良好的腐蚀防护作用。

Through survey carefully, we find that if depend on pouring velocity、structural shape of SEN entocoele、angle slope of outlet 、depth of infusion together to make the liquid steel in model revolution in an order flow then it can utilize this kind of energy completely.

通过仔细研究发现，只要依靠浸入式水口内腔结构形状、出口倾角、浸入深度以及浇注速度就可以使方坯连铸结晶器内钢水为旋转的涡流流动，把液态金属的流动动能利用起来。
