(6), the temperature in the furnace cupola is elevated to 900-1200 ℃, the material in the furnace cupola is carried out melting;
(7), open furnace cupola, emit molten iron, and in molten iron, add the copper of 0.6%-0.75%, the chromium of 0.5%-0.6%, the molybdenum of 0.4%-0.5%, the temperature when emitting molten iron is 1400-1450 ℃;
(8), with bull ladle molten iron is poured in the die cavity and cast;
C, unpacking, shipment:
(1), take apart casing outer hang tight filament;
The molten iron piece that splashes when (2), choosing the tank surface cast;
(3), open casing;
(4), the inside and outside molding sand soil of cleaning casing medium casting;
(5), foundry goods is put into compressed air shotblasting machine and carry out bead;
(6), after ball blast finishes, the shot blast room door is opened automatically, and foundry goods is taken out;
(7), with foundry goods polishing cleaning, brush antirust paint, shipment.
The present invention compared with prior art has the following advantages: the present invention adopts furnace cupola to carry out melting, and fusion process control is convenient, and product percent of pass is high; It is short to change iron time and melting cycle, and productivity ratio is high, produces the chain space compact in design; Craft flexibility is good; Operating cost is low, and pollutant emission is few, improves working environment and ecological environment.This manufacture craft can guarantee the stable high-quality iron liquid that obtains, and foundry goods tissue, the performance of generation is good, the quality fluctuation scope reduces, qualification rate high.
