Manufacturing method of iron carbide |
| abstract |
(57) [Summary] [PROBLEMS] In the production of iron carbide, which mixes hydrogen sulfide into a reducing gas atmosphere for the production of iron carbide and appropriately controls the sulfur activity according to the reaction temperature, is usually inevitable as a bustle gas or the like. To minimize the reduction reaction hindrance caused by the incorporation of oxidizing gases such as H 2 O and CO 2 which are mixed in by-product or by-produced by the reduction reaction, and ensure a stable and excellent iron carbide production rate. . SOLUTION: In a method for producing iron carbide by reducing and carbonizing iron oxide in the presence of a reducing gas containing hydrogen and a carbon compound, which can accompany an oxidizing gas, the sulfur activity in the reducing gas is determined by the reaction temperature. And reducing and carbonizing at a pressure exceeding atmospheric pressure. |
