Power casting needs special die casting machine, and equipment investment is expensive, and liquid forging both available dedicated hydraulic press, it is also possible to general oil pressure
Machine, equipment investment are smaller.
6 product costs are low.Due to substantially increasing the stock utilization of product, equipment investment and mould expense are significantly reduced
With, and reduce and heat consumed heat energy, therefore product cost reduces than other techniques.
Steel-casting is produced using the technology of the present invention, due to eliminating the remelting energy consumption of rising head, ton product comprehensive energy consumption does not surpass
700kgce is crossed, lowers 30% or so than Foundry Production.Due to replacing sand mold using metal mold, the discharge of ton casting antiquated sand is no more than
1kg, more than 99% is reduced than Foundry Production；Because the product yield without rising head, molten metal generally reaches more than 90%, than casting
Make production and improve 20~30 percentage points；Because pressurization cooling, solidification and feeding, casting quality stability significantly improve, cast
Percent defective is less than 1%, and more than 1 times is reduced than Foundry Production；Due to being substantially reduced without sand operation, solid waste discharge, casting is thoroughly eradicated
Make the anthraco-silicosis of industry.Equally by 50,000,000 tons of calculating of casting annual production, after the present invention, 50,000,000 tons can be reduced every year
Antiquated sand discharge or processing above；At least more than 400,000 tons of the material scaling loss brought by the remelting of waste product and rising head can be reduced,
More than 50 hundred million yuan of value；Reduce by 12,500,000 tons of melting power consumption, by 800 degree of calculating of ton steel melting power consumption, power consumption can be reduced every year
10000000000 degree.
