Aluminum slag balls have the functions of deoxidation and synthetic refining agent. 之间，硬度达到单粒承重 75公斤，最主要是观察铝造渣球各种含量成分的均匀度，一般经过强力搅拌压制出来的铝造渣球各种理化质变含量均匀稳定，使用效果一致，不出现浮动。 The aluminum slag ball has a uniform particle size, maintained between 15-50mm , and the hardness reaches a single weight of 75 kg. The most important thing is to observe the uniformity of the various content components of the aluminum slag ball. The physico-chemical qualitative change content is uniform and stable, the application effect is consistent, and there is no floating. It can be used as a deoxidizer to remove free oxygen in the steel when it is initially made. In addition, it can quickly form a slag and cover the liquid surface to isolate the air.
钢包精炼位时加入，以调整渣的组分，尽快脱去渣中的氧得以快速形成适宜的精炼渣系。 There are two forms of aluminum slag ball addition: First, the electric furnace is added as a deoxidizer and other types of deoxidants at the same time during the tapping process to reduce the dissolved oxygen in the steel to a controlled range; In order to adjust the composition of the slag, the oxygen in the slag can be removed as soon as possible to quickly form a suitable refining slag system.
Application in actual production:
, 电炉工序加入。 1. Electric furnace process is added. 硅钙钡 ,2.0-3.0kg/t 。 After the furnace, the final deoxidizer uses aluminum slag balls and silicon calcium barium. According to the end carbon content, the amount of deoxidizer is added: aluminum slag balls 0.5-1.0kg / t; silicon calcium barium , 2.0-3.0kg / t . 开始向钢包内加入硅钙钡、铝渣球，出钢时间大于110秒，出钢严禁下渣。 Adding sequence: 20 tons of molten steel begins to add silicon-calcium-barium and aluminum slag balls to the ladle. The tapping time is greater than 110 seconds.
, LF 炉精炼工序。 2 , LF furnace refining process. 50-100kg;电石粉、硅铁粉为20-30kg.火砖沙为15-25kg 。 During refining, the composition and slagging are adjusted according to the composition of the molten steel. The slagging agent is added as follows: aluminum slag balls, 50-100kg; calcium carbide powder, silicon iron powder, 20-30kg .
, 脱硫情况。 3 , desulfurization situation. 分钟内可以变白，对脱硫和去夹杂相当有利。 The aluminum slag ball is used for fast slagging and high desulfurization efficiency. The slag sample refining can turn white in 15 minutes, which is very beneficial for desulfurization and de-inclusion.
