(5), to the mould drying after the moulding, repair type, and at its surface brush coating;
B, melting:
(1), preparation pool furnace charge, pool furnace charge comprises the fire clay of 20-25%, the quartz sand of 20-35% and the water of 40-55%;
(2), pool furnace charge is filled in the intermediate frequency furnace, process pool stove, and the eye that on the stove of the pool, blows in;
(3), the temperature in the intermediate frequency furnace is transferred to 500-700 ℃, pool stove is dried;
(4), light a fire in the intermediate frequency furnace, temperature is elevated to 900 ℃;
(5), in the stove of the pool, feed, the material of dress comprises: the steel scrap of the new iron of the coke of 5-7%, 35-42%, the old iron of 15-22%, 35-42%, the silicon of 0.6-0.7%, the manganese of 0.6-0.7%, the iron of 0.6-0.7%;
(6), the temperature in the intermediate frequency furnace is elevated to 900-1200 ℃, the material in the intermediate frequency furnace is carried out melting;
(7), open intermediate frequency furnace, emit molten iron, the temperature when emitting molten iron is 1400-1450 ℃;
(8), with bull ladle molten iron is poured in the casting mold mould and to pour into a mould, stopped 1-5 minute;
(9), when solidification layer reaches desired thickness, pour out unnecessary molten iron;
(10), after cooling the cleaning, promptly obtain required foundry goods;
C, unpacking, shipment:
(1), foundry goods is put into compressed air shotblasting machine and carry out bead;
(2), after ball blast finishes, the shot blast room door is opened automatically, and foundry goods is taken out;
(3), with foundry goods polishing cleaning, brush antirust paint, shipment.
The present invention compared with prior art has the following advantages: the present invention can be used in continuous production, enhances productivity, reduced production cost, the noise pollution of having avoided available technology adopting punching press, bending to bring, more environmental protection.Molten iron after the present invention will be dissolved casts directly in the casting mold, makes molten iron and the moulding of mo(U)ld face crystallization and freezing, unnecessary molten iron is poured out, to obtain crossbeam.Technology of the present invention is simple, and is easy to operate, not limited by smelting furnace, can cast large-scale crossbeam, and the casting section thickness degree can be controlled simultaneously, and cost is low.
