Modelling |
1. Strictly control the quality of type (core) sand, ensure the strength and control of water 2. Sand tamping, inclined surface polishing, paint brush twice 3. Place the pouring riser and cold iron according to the process requirements 4. Clean and bake as required cavity |
sand mixer |
Check the quality of type (core) sand and surface sand 2. Check the cavity size Check the baking time |

Smelting casting |
1. Choose low S.P pig iron, select scrap steel, auxiliary materials and alloy of baking furnace according to process 2. According to special process smelting, make steel S.P hazardous elements meet internal control standards 3. The finished molten steel is treated with argon blowing in the ladle and R-H vacuum circulation degassing to make the molten steel composition uniform, harmful oxygen (H, O) reduction, uniform temperature, increase the fluidity of molten steel, so as to ensure good liquid replenishing of the casting and prevent the casting from porosity and other defects Strictly control casting temperature and casting speed according to the provisions |
50 t furnace R-h vacuum circulation degassing equipment for ladle argon blowing device |
1. Furnace materials must meet the technological requirements 2. Control feeding temperature, feeding quantity, pure boiling time, steel temperature 3. The direct reading spectrometer is used to quickly detect the chemical composition in front of the furnace to ensure that the equipment is in the best state during melting and the chemical composition of the finished product meets the requirements during pouring 4. Check the parameters of argon blowing and R-H vacuum treatment 5. Check the starting temperature and Pouring time |

Cleaning and heat treatment |
1. The internal heat preservation time of casting mold shall not be less than the process requirements 2. Sand falling, shot blasting, cutting and pouring risers meet the technological requirements 3. Strictly carry out the blank heat treatment To ensure the uniformity of furnace temperature and refine the original structure of casting |
50t Inert falling sand machine and 8.5 ×12m Heat treatment furnace |
1. Check the furnace temperature record 2. The sample is heat-treated with the casting in the same furnace, and the mechanical properties are sent to be checked immediately 3. Check the surface quality of the blank Quantity, geometric dimension and machining allowance |
