The small changes in carbon content have an important influence on the microstructure and properties of the alloy. Precise carbon control is a key factor and key link in the process of producing cemented carbide from crushed materials. Carbon quantity control is to control the oxygen and carbon balance in the production process, strictly control the oxygen content in the crushed material, make full use of the aerobic reaction in the wet grinding process, and the process of removing the forming agent and the oxygen in the sintering process to control oxygen. The means to achieve the purpose of carbon control and improve the quality of products.
