目前沸腾钢钢锭表面结疤缺陷仍较严重,公司1963年结疤废品达9024吨,占轧后废品总量的26.3%。据观察,与浇注时钢液在锭模内的激荡飞溅有关,尤其是用八锭底板浇注时更为严重。为此,我们作了八锭板浇注模型初步试验,以了解靠近中注管的四个绽(以下简称内锭)在浇注初期液面激荡飞溅情况和液面上升的速度,离中注管远的钢锭(以下简称外
At present, the surface of boiling ingot steel ingot surface scarring defects are still serious, the company in 1963 scarred waste reached 9024 tons, accounting for 26.3% of the total rolled scrap. It is observed that with pouring liquid steel in the ingot mold agitation splashed, especially when using eight base plate pouring more serious. To this end, we made a preliminary test of the eight-ingot casting model to understand the four in the near-in-pipe bloom (hereinafter referred to as the ingot) in the initial pouring of the liquid level oscillation splashing and the rate of liquid rise away from the tube Of ingot (hereinafter referred to as the outside
