摘要
为解决螺纹钢加速冷却后容易生锈的问题,结合其生产工艺现状,在其穿水冷却过程中提供加速氧化气氛,以形成致密氧化膜.利用氧化膜的防护作用,控制螺纹钢基体氧化,达到防锈目的.螺纹钢加热快速冷却后通过喷射雾化的H2O2处理,电子探针分析观察到钢筋表面致密氧化膜从3-4μm增加到17-18μm.样品经过干湿交替加速腐蚀试验,结果表明:经过H2O2处理后的螺纹钢开始生锈时间从2 d延长至14 d,防锈性能得到大幅度提升.
It is easy for the rebar to rust- eaten after the water cooling process. In order to solve the problem,an experiment was carryed where a strongly oxidative atmosphere was provided to produce a dense layer of the oxide,so that base metal can be prevented from further rust- eaten. After heated,the rebar was sprayed by atomized H2O2.The electron probe analysis showed that the oxide layer increases from 3 - 4 μm to 17 - 18 μm. After several times of dry and wet corrosion test,it was showed that the time for the rebar to be rusted changes the from 2 days to 14 days.It is believed that the authors method is feasible.
