Types of carburizers
There are many kinds of recarburizer, graphite petroleum coke, calcined petroleumc coke, and CAC, and its application is also very wide. In the foundry industry, recarburizer can be used in those aspects. Here is a recarburizer manufacturer, Zhengzhou Minmett, to introduce you in detail, hoping to help you.
(1)High quality castings production of nodular graphite castings to use good quality recarburizer, such as Graphite petroleum coke, and graphite electrode recarburizer, index is the carbon content of 98.5%, sulfur is 0.05%.
(2)The production of common ductile iron recarburizer and gray iron for ordinary castings does not need the application of coal recarburizer. The main indexes , the content of carbon is 90%, 95%, the content of sulfur is better between 0.1-0.5.
(3)In general, the most commonly used in steelmaking is coal recarburizer, and the absorption rate is not relatively high.
(4)Special castings, such as the production of brake pads, the use of oil coke recarburizer is more than a little, the absorption rate is more than 80 percent.
The above is the type of recarburizer most commonly used in the foundry industry.
