- Process detail treatment of pouring ladle for aluminum casting
- Editor：Hangzhou Hongcheng Pml Precision Mechanism LtdDate：2015-12-25 15:38 Click：
Hongcheng is Hangzhou gravity casting , aluminum casting manufacturers, the treatment of casting ladle is a very important link, in the specific operation, first remove the residue from the iron bag, clean the bag thoroughly; package The wall brush a mixture of bentonite and water, add viscosity, add the viscosity, add the refractory, the thickness is controlled in the 120-150mm, and the bottom of the bag is stout and no crevice; then the sand is made out of the wall, the wall thickness is 50-60mm, the wall is sturdy with the stick, the wall of the ladle is higher than the outer edge of the ladle; the corner of the wall and the bottom of the bag should be made into a round angle to prevent the collection from the collection. At the same time, remove the edges and corners of the ladle and make the arc shape to prevent inhalation; the ladle repair finished requires smooth lining without damage
in addition to the ladle preheating, the use of wood and kerosene to ignite the baking, require light to take light, prevent damage to the refractory layer, start a small fire slowly baking, the surface dry after the fire, to ensure that the ladle drying and baking, pay attention to the refractory layer of molten iron can not be baked out of cracks The heat can not be lower than 800 centigrade before pouring, the temperature can not be lower than 800 degrees, the inner wall of the ladle is red or dark red, and the molten iron is heated in the furnace. The ladle spoon should be baked in advance, drying and drying, and the casting is not used to prevent the casting from casting out 3 of the gas holes, so as to ensure the temperature of the molten iron and the temperature of the molten iron. In order to ensure the survival rate of the products, the casting process needs to improve the operating speed. The iron water is slowly added to the beginning of the furnace. The iron flow is stable after the flow is stable, and the tilting switch of the electric furnace is well controlled.
