Notes for opening the furnace

Tweet

Before opening the furnace the medium frequency furnace must need check on electrical equipment, water cooling systems, sensors and other brass check only under these circumstances in order to open the device intact furnace, heat treatment to ensure the safety, otherwise prohibited furnace; This is also copper equipment manufacture should know. OK responsible for power transmission and furnace staff, and is responsible for personnel are not allowed to leave their posts, while working on the external conditions necessary sensors and crucible regulation to prevent people in the power transmission touch sensor and cable, the impact of intermediate frequency electric furnace normal operation or the occurrence of safety accidents. Second, notes after opening furnace After electric furnace opening, during loading, response within the charge to be checked, to avoid mixing explosive and other hazardous materials in the customized copper casting machine. In order to prevent the phenomenon of knot cover, is prohibited in molten steel directly into the cold and wet feed materials, as well as in the melting liquid filled to the upper rear of the block shall be added to a larger volume of material; To avoid accidental explosion, it is necessary to ensure that the site and pouring furnace former pit no water, no obstacles; and during pouring Two persons are required, and the remaining liquid steel can only pour in the development of location, can not be everywhere Dumping. Third, maintain precautions when maintenance the customized graphite mould and other products. When talk to the maintenance of furnace, frequency generator room should be kept clean, non-flammable materials stacked. Excessive loss of melting furnace repair promptly when fettling to avoid iron, iron oxide mixed to ensure crucible dense.
