FORFARANDE FOR FRAMSTELLNING AV PULVERFORMIG, LETT FLUIDISERBAR AVSVAVLINGSBLANDNING |
摘要 |
Improved desulfurization of ferrous melts is obtained by injecting into the melt a readily-flowable desulfurization composition composed of a desulfurization agent, such as calcium carbide or the like and, if desired, an additional component in which the particles are finely ground with about 3 to 20% by weight of carbon for at least about five minutes to coat the particles with a solid, lubricating coating of carbon. |
