The scope of application and content detection method of carburizing agents for cast iron smelting process, it is found that if the silicon content in the cast iron liquid is relatively high, the carbon dissolved in it tends to precipitate as graphite. Under these conditions, if carburizing in the molten iron is difficult and the silicon content in the molten iron is low, it is relatively easy to carburize. Therefore, carburizing in the cast iron smelting process should be carried out before silicon addition. The selection of carburizing agents for castings should fully consider the different absorption rates of carburizing agents. Carburetting agents are additives used to increase carbon content. Do you know their scope of application and testing methods?
There are many kinds of raw materials and different processes for petroleum coke carbonizer. The main method is to use graphite for compression molding, which requires the addition of too much binder for molding, and the carbon content generally does not meet the requirements of carburizing agents.
The compressed graphite powder, due to its solid block shape and lack of porous structure, has a lower absorption rate and absorption rate than graphite carburetors formed by calcination and calcination.
High quality carburetors generally refer to carburetors that have undergone graphitization. Under high temperature conditions, the arrangement of carbon atoms takes on the microscopic form of graphite. Graphitization can reduce the content of impurities in the carburizing agent, increase the carbon content of the carburizing agent, and reduce the sulfur content.
1. Scope of application of carburetors: Carburetors are widely used in the decarburization of steel smelting and casting processes, especially in the ductile iron gray iron industry with high product quality requirements and strict sulfur content control. It can also be used as an adsorbent for heavy metal wastewater treatment and as a raw material for graphite cathodes in aluminum electrolysis cells.
2. Main analysis and detection methods of petroleum coke carburetor
The content of silicon requires atomic absorption detection (with high detection efficiency and accurate values).
The particle size of graphitized petroleum coke carburant must be measured by resistance particle analyzer (high efficiency).
The particle size detection of petroleum coke carburant requires the Ruisi RA200 particle analyzer. (It can analyze the roundness of particle shape coefficient more accurately).
