(1) A good graphitization carburizer should also have the characteristics of high carbon, fast decomposition speed and high absorption rate;
(2) A good graphitization carburizer has very low harmful elements, low sulfur and low nitrogen;
(3) Graphite carburizing agent is added to molten steel and iron in a more uniform layered manner. It can refine its distribution in molten steel and iron to make absorption and performance more stable.
(4) In general, it is also key to choose the size of different particles according to the size, power and dissolution time of the furnace. Generally, more particles with the size of 0.2-2mm and 1-5mm are used.
