When the ramming material of the intermediate frequency furnace is in use, the molten steel has viscosity slag, how to solve it?

When the ramming material of the intermediate frequency furnace is in use, the molten steel has viscous slag. How to solve it? Some customers are using scrap steel to make synthetic cast iron, and the scrap steel is seriously corroded. Slag, it is very laborious to remove the slag every half of the furnace, so how to solve this problem, the raw material cannot be replaced? Here is a suggestion from Hengtong Refractory: If you don't change the material, you can make the slag thinner, add some broken glass, etc. It is better to find some glass with green glass fractures: it refers to normal colorless and transparent glass. After breaking, from the cross section, it has a light green color. This kind of glass is commonly known as: sodium (calcium) "Glass". Sodium (calcium) glass is mainly composed of 2 silicon oxide, and also contains 15% sodium oxide and 16% calcium oxide, which is weakly alkaline after melting. It does not refer to colored glass with added coloring elements._Scrap steel Acid slag is formed after rusting into slag. Adding soda glass will reduce the viscosity of acid slag. After scrap steel is corroded into slag, acid slag will be formed. If the slag is excessively formed, most of the molten iron will be oxidized.
