日本三菱重工业公司广岛研究所和广岛造船厂,为了提高轴承钢连注的质量和扩大连注钢种范围,就轴承钢连注时采用电磁搅拌共同作了试验室试验,进而又在连注机上作了现场试验,就连注+电磁搅拌轴承钢的结晶组织、中心偏折、以及碳化物尺寸等作了分析。试验方法及试验条件如下:电磁搅拌装置是该所自制的,电磁搅拌采取的是旋转磁场方式三极三相电流。首先在模拟试验装置(如图1)上作了各种条件试验,然后在现场连注机上作了200 mm方坯
Japan’s Mitsubishi Heavy Industries, Ltd. Hiroshima Institute and Hiroshima Shipyard, in order to improve the quality of bearing steel continuous injection and expand the scope of continuous injection of steel, the bearing steel continuous injection of electromagnetic stirring together made a laboratory test, and then in the continuous injection machine Made a field test, even the note + electromagnetic stirring bearing steel of the crystal structure, center deflection, and carbide size were analyzed. Test methods and test conditions are as follows: Electromagnetic stirring device is made by the home, electromagnetic stirring is taken in the way of rotating magnetic field three-pole three-phase current. First of all in the simulation test device (Figure 1) made a variety of conditions on the test, and then on-site continuous injection machine made 200 mm billet
