| Abstract: | Factors influencing heat-sending proportion of continuous casting square billet (rectangular bloom) transport may be different in various enterprises and under various producing condition. However surface cracks on the billets should share common characters. Study on cracks of the square billet (rectangular bloom) produced by 2nd Plant of Tangshan Iron and Steel Corporation was conducted and counter measure was taken according to results. The effect is good. |
