Analysis of Refractory Sintering Process of Core Furnace

Industrial furnace iron liquid treatment, sensor removal and docking of this work for the sensor replacement of the core part of its quality and progress related to the success of the entire construction. The temperature of the furnace refractory lining can not be reduced to below 80 ℃ during the quick change process, otherwise the lining will be cracked to affect the life of the entire lining. Therefore, in ensuring the quality of construction under the premise of the progress must be. In addition, the throat cleaning is particularly important, the electric furnace throat should be as far as possible to remove the original size; docking surface of the slag must be clean, to ensure that the opposite paste Yan, or easy to lead to the interface of leakage of molten iron. To empty all the molten iron from the throat, you should protect all the hose in the pit to prevent being burned.
When the resumption of transmission for the sensor refractory material sintering, melting solid iron mold temperature reaches the left and right, that is, iron began to melt, should be injected into the furnace iron injection, or there may be broken. So the melting of the 5 - 8t molten iron in addition to the normal process by the cupola to provide, but also should be emergency prepared. If the furnace temperature measurement of the thermocouple accidental damage, should be based on changes in the coil current to determine when the liquid into the liquid, because the melting mold temperature exceeds the magnetic transition point 70 ℃ (Curie point), the cast iron organization Of the ferrite that becomes non-magnetic, the magnetoresistance increase map, according to the transformer principle, will lead to coil current surge, this time can be injected into the molten iron. The site should be prepared enough of the trough, in the new sensor for leakage of molten iron or broken trench accident, the electric furnace filled with molten iron (for 30t with a core furnace, the furnace will be up to 45t molten iron) To save the furnace refractory lining and equipment to prevent accidents to expand and reduce losses.
