Rolling Bearing Isc B00150 Steel Lf Refining Process - China

ISC B00150 steel is a low-carbon steel.

The LF refining process aims to improve its purity and precisely control its composition and temperature.

The following are the main steps and key points of the LF refining process for ISC B00150 steel in general:

1 - Pre-refining Preparation: Carefully inspect the operating status of all LF furnace systems, including electrodes, argon gas, and furnace cover.

Also, verify whether the accident pit is free of water and that raw materials, tools, and alloy silos are in normal condition.

2 - Tapping and Preliminary Treatment: During tapping, ensure proper slag control and limit the amount of slag released to no more than 5 kg/t to prevent excessive oxidizing slag from entering the ladle and impacting subsequent refining.

After the ladle receives the molten steel, the ladle car is moved to the refining station, and argon gas is connected for purging.

Simultaneously, lime, fluorite, composite deoxidizers, aluminum granules, and other materials are added for rapid slag formation.

3 - Arc Heating and Slag Optimization: An electrode is lowered and inserted into the slag, and the arc is used to heat the molten steel.

To reduce heat loss and erosion of the furnace lining, ISC B00150 steel is generally heated using submerged arc heating.

During the heating process, the argon flow rate, current level, and slag viscosity are adjusted according to the smelting progress and slag conditions.

Slag formation is usually based on the white slag method.

The slag basicity R ≥ 4 is controlled, and the w(TFe+MnO) content in the slag is ≤ 1.0%, forming a slag system mainly composed of CaO-Al₂O₃-SiO₂.
