在实验室竖式电阻护和中频感应炉对Si系发热剂Si-Fe、Si-Ba-Ca、Si-Al进行了升温试验，升温速度为4～11℃／min．升温值为20～40℃；并对300t钢水进行了工业性试验，升温速度为3．5℃／min，升温值为14℃。
The Si-Fe, Si-Ba-Ca, Si-Al Si-based heat-generating agents were tested in a vertical resistance furnace and a medium-frequency induction furnace at a heating rate of 4 to 11 ° C./min. Heating value of 20 ~ 40 ℃; and 300t molten steel for industrial tests, heating rate of 3.5 ℃ / min, heating value of 14 ℃.
