Jisheng graphite crucible is used for smelting: copper, brass, electrolytic copper, lead, aluminum, zinc, and other non-ferrous metals, please pay attention to the following points when using: 1, graphite crucible most avoid moisture, must be placed in the indoor dry place or wood frame, keep ventilation, do not get damp, damp after use easy crack.2, each crucible before use must be in drying equipment or to preheat baking furnace, especially the crucible of be affected with damp be affected with damp, baking temperature of low temperature of 100 degrees once started, the speed of temperature is not higher than 30 degrees per hour oven to 150 degrees, 8 hours, heat preservation can be drying, drying in stove of crucible at least place more than one class, and often turn, change direction, crucible wall feel hot.3. The melting time of the first furnace shall be at least twice that of the normal melting time of the first furnace, so as to prevent the melting pot from containing cracks as a result of too fast heating, which may lead to the cracking of several fires.4. After the use of the crucible, the remaining cold bottom (cold metal) of the crucible should be poured out, and then new materials should be cast. When the material is cast, it must be gently put into the crucible with care, and no sharp throwing is allowed.The material should be put according to the capacity of the crucible, not too much, too tight to avoid the metal thermal expansion, swelling crack crucible.
