Lift portion is positioned at the top of crystalline portion, comprise driving mechanism, constant speed case, sprocket wheel chain, last lifting clamp, following lifting clamp, driving mechanism provides lifting power, and constant speed case, last lifting clamp, following lifting clamp connect into a power transmission system by the sprocket wheel chain.
Truncation part mainly comprises cutting device, and when cast tube promoted sufficient length, cutting device blocked cast tube in the stroke of last lifting clamp.
Move the topmost that tube portion is positioned at equipment, comprise dump car, unload material clamp, the duplex type electric block forms.
Put the rear side of tube portion, comprise and put pipe unit, 3T hoist engine composition in device bottom.
The present invention produces the processing step of cast iron pipe:
1, molten iron crystallization.Ladle constantly is transported to tundish to molten iron by electric furnace, the tundish rotation makes molten iron flow into the insulation bag, molten iron in the insulation bag flows into crystallizer by U type passage, there is recirculated water the crystallizer outside, inside is graphite cannula, molten iron is taken away heat by recirculated water after entering graphite cannula, and molten iron constantly crusts, and is drawn and continuous drawing by dummy ingot after crust reaches certain thickness.By the drawing of control law move form wall thickness evenly, cast tube with regulation overall dimensions.900-1000 ℃ of crystallizer outlet temperature.
2, cast iron pipe promotes.The lifter motion drive path is: adjustable speed direct current generator-driving mechanism 1-constant speed case-sprocket wheel chain-last lifting clamp, following lifting clamp.
The lifter motion frequency is controlled according to cast tube wall thickness, crystallizer outlet temperature.
Promote two lifting clamp that the execution of action drives by the sprocket chain bar, alternately finish.
3, cast iron pipe blocks.Cutting device blocked cast tube after cast iron pipe promoted certain-length.
4, cast iron pipe shifts out.Cast tube after blocking shifts out by the discharging clamp and with the dump car walking.
5, cast iron pipe skews.The cast tube that shifts out is put into the voltage regulator tube device with unloading material clamp in the decline of the control lower edge of duplex type electric block guide rail, and hoist engine control voltage regulator tube device skews cast iron pipe.
Characteristics of the present invention:
1, the material inherent quality improves a rank than the product with the conventional cast explained hereafter, such as the HT200 with the conventional cast explained hereafter, is exactly HT250 with this technology.
2, save material 20%-40%; Save cutter; Cost is low.
3, working (machining) efficiency height.
4, energy savings, green casting, pollution-free.
5, bottom filling molten iron injection mode, impurities of materials is few.
6, technology is injected molten iron, outer crystallization mode by the bottom, causes matrix densification, tiny, the no conventional cast defective of crystal grain.
7, no conventional cast running gate system, product yield rate height.
8, cast iron pipe dimensional accuracy height, amount of machining are little.
Description of drawings
