Because the conveying mechanism 3 is sequentially provided with the spheroidizing unit 6, the ladle transfer unit 7, the slag skimming unit 8 and the vermiculizer unit 9 along the conveying direction, the pouring ladle 4 or the transfer ladle 5 can be selectively processed by the spheroidizing unit 6, the ladle transfer unit 7, the slag skimming unit 8 or the vermiculizer unit 9, so that the conveying mechanism is suitable for production and transportation of various iron liquid, realizes collinear transportation of various iron liquid, does not need to switch production lines, reduces the transportation conditions of a span line and a device, solves the problems that when a crown block is lifted, the iron liquid ladle directly passes above the device, equipment or personnel damage is possibly caused by falling or overturning of the iron liquid ladle, and the personal safety of operators is influenced; when fork truck fork fortune, need pass through workshop passageway, it is great to equipment or personnel's influence, has the security not high, the easy problem of incident that appears.
In this example, the multiple-variety collinear molten iron delivery system may be used for cast products including three of gray cast iron, ductile iron, and vermicular cast iron. When gray cast iron is carried out, the pouring ladle 4 is placed on the transfer mechanism 2, after the iron liquid of the electric furnace unit 1 reaches the tapping temperature, the electric furnace unit 1 is manually operated to pour the iron liquid into the pouring ladle 4, after the iron liquid weight of the pouring ladle 4 reaches the set weight, tapping is stopped, the pouring ladle 4 is transferred onto the conveying mechanism 3 by the transfer mechanism 2, after being processed by the slag skimming unit 8, the pouring ladle 4 is continuously transferred to the pouring unit 10 by the conveying mechanism 3, and the pouring machine is used for taking out pouring.
