How to use graphitized petroleum coke correctly?

Graphitized petroleum coke as a carbonizing agent is different from other types of carbonizing agents. The carbonizing agent adopts graphitization. The carbonizing agent is not stable during use, and has less impurities. As a carbonizing agent, it introduces less new impurities into the molten steel. , It has a great auxiliary effect on the purification and carbonization of molten steel. Graphitized petroleum coke is suitable for nodular cast iron with strict requirements for sulfur. It has high fixed carbon content and good absorption rate. It is suitable for intermediate frequency furnaces of 0.5 tons to 12 tons.

There are also traces of the use of graphitized petroleum coke, let's take a look at its use.

1. After placing one-third of the furnace at the bottom of the furnace, place the calculated product on the furnace, and place the remaining furnace as required. If the upper furnace is large, in order not to affect the floating absorption rate, break it The furnace is pressed on the carbonizing agent.

2. Supply a small amount of iron cut, carbonizing agent, scrap steel, and reheating materials in the order. Basically, the absorption of the carbonizing agent is above 88%, reaching 95%, and the slag can be discharged when the temperature is increased to 1560°.

If the molten iron in the furnace does not come out, reserve a part of the molten iron, add carbonizing agent, iron filings, scrap steel, etc. The carbonization agent is directly added to the bottom of the furnace to cause excessive burning loss of the carbonization agent. Reserve a part of the molten iron at the bottom of the furnace, or place a part of iron pins at the bottom of the furnace, and the absorption will be higher.

Various additives are used in smelting. Graphitized petroleum coke is generally used to increase carbon in the later stage of smelting, and the requirements for impurities in additives are strict. Graphitized carbonizing agent has stable performance, few impurities, and does not react with other elements after being added. Its use as a carbonizing agent can improve the carbonization effect, so it is widely used and has been well received by many manufacturers.
