Graphite carbon raiser is now more and more recognized by many manufacturers. As a new type of metallurgical material, it is commendable, but the main reason is many advantages of graphite carbon raiser have been attracting manufacturers to use, even some manufacturers plan to purchase graphite carbon raisers every month, but the problem that has always plagued manufacturers when using graphite carbon raisers is how to increase the absorption rate of graphite carbon raisers. Through the following methods, hope everyone can use graphite carbon raiser better.

 

1. If you want to solve the problem of the absorption rate of graphite carbon raiser, you have to work on the raw materials of graphite carbon raiser. When selecting graphite carbon raisers, we should choose graphite carbon raisers with moderate particle size and high density. Because the denser the graphite carbon raiser, the larger the particle size, the less it is easy to absorb. In order to make the graphite carbon raiser achieve a higher absorption rate, to prevent the graphite carbon raiser from being oxidized at high temperature for a long time, the initial power during the melting process should be small enough to extend the heating time of the graphite carbon raiser to increase the absorption rate.

 

2. The correct feeding method is also one of the factors that affect the absorption rate of graphite carbon raiser. In order to avoid slow smelting and heating time of graphite carbon raiser, during the batching process, scrap steel and carbon raiser are added in batches, and each batch of charge is melted. The time is about 15 minutes. In the early stage of the chemical compound, a lower power is used to avoid the burning of the graphite carbon raiser caused by excessive temperature. Later, it is expected that the molten iron will heat up quickly after it is paste. If a total of 130KG of carbon raiser needs to be added, use the method of 60KG+40KG+30KG to add it, which avoids that the graphite carbon raiser added in a large amount is suspended on the surface of the molten iron, which cannot be effectively combined with the molten iron and the temperature is too high. The burning loss is serious, and the amount added at the last time should be relatively small, so as to avoid adding graphite carbon raiser to the molten iron in large quantities, resulting in incomplete absorption of the graphite carbon raiser in the molten iron and production delays.

 

3. Mechanical and artificial mixing is often a feasible way to increase the absorption rate of graphite carbon raisers in use! Combining mechanical stirring with manpower can effectively improve the absorption rate of graphite carbon raiser. Appropriate manual stirring at the same time as mechanical agitation, such as the use of transfer package to pour molten iron to promote the dissolution and diffusion of graphite carbon raiser to increase the absorption rate. The specific gravity of graphite carbon raiser is small. Manual stirring can reduce the burnt loss of graphite carbon raiser due to floating on the surface. Stirring can also reduce the holding time of graphite recarburization and shorten the generation period. However, if the stirring time is too long, it will cause serious burning of the carbon raiser. Therefore, the appropriate feeding process and melting power also play a more important role in the absorption of the graphite carbon raiser.
