Research description of boron-free ramming mass materials for induction furnace 无硼捣打料研究说明
Research description of boron-free ramming mass materials for induction furnace The main failure forms of furnace lining mainly include the following: 1. Thermal stress cracking, furnace lining in the use process of use, the lining contacts high temperature metal liquid, the outer layer is close to the water cooling coil, the temperature difference is huge, after the periodic cold and heat cycle, cause volume expansion and contraction, easy to lead to the furnace lining thermal stress cracking, expansion and peeling phenomenon. 2. Chemical erosion, C and FeO in steel water form a chemical reaction with the furnace lining at high temperature, SIO2 + 2C —> SI + 2CO, SIO2 is reduced by C; FEO and SIO2 to FEO.SIO2 low melt at about 1170 degrees, quickly separated from the furnace lining under the stirring of high temperature steel water. 3, Electromagnetic mixing and local overheating caused by mechanical erosion, furnace lining is in the process of steel water contact, local may appear a series of chemical and physical reaction, cause local overheating, form local liquid phase, in electromagnetic stirring, and steel water erosion process, easy to form furnace lining defect, cracking, in cracking and defect is prone to appear furnace lining...Read MoreThe first chinese DC EAF type of Enrichment of platinum project succeed
