By means of continuous casting & rolling, this line works to produce oil-free conductive aluminum rod in a diameter Ø9.5mm 、Ø12mm.
Brief Process flow:
Ordinary aluminum ingot and scrap →Melting furnace→ holding furnace→ 4-wheel continuous casting machine → front drive unit → roller shears→ continuous rolling mill → cooling & lubricating device for aluminum rod → twin-basket continuous coiler→ oil-free aluminum rod
Molten aluminum or prepared aluminum melt flows from the holding furnace into the 4-wheel casting machine via the launder and is casted into trapzoid-shaped bar in a cross-sectional area of 2400mm2. Then Cut off the bar which does not meet the technical requirements with the roller shears, press the front end and feed it into the rolling mill. After milling is completed, the rod will be coiled into the basket.
The slags from steel and ferrous alloy can be used to make mineral wool (rock wool) in hot status directly from Submerged Arc furnace and blast furnaces. The most popular raw material is Manganese slag (Mn slag). It is of energy savings and environmental friend. The production cost is much lower than basalt rock wool.

Steel Rolling Mills
Beijing Holland will participate METEC, 25-29 June 2019, for the promotion of steel rolling mills for strip coil, plate, Rail, Piles,rebar and rod as well as universal profile rolling mill for I-beam, H-beam (IPE, HEA and HEB ), U-beam ( channel ), Angle and various shapes.
There are two major melting methods for ferrous casting, Cupola and induction furnaces. There are many factors for decision makers in trading off. Cupola is more used for high quality large quantity production. The induction furnace is good for medium and small scale production as well as alloy iron. The cupola plus induction furnace is superior for casting but only poor in cost control. The detailed comparison is summarized as follows:
Melting Mode Cupola Induction Cupola+Induction

l Different proportions of scrap steel, chips, primary iron, and recycled materials can be used; the C and Si contents in the furnish can be significantly different from the molten iron; the slag iron and some pellets can be used; Less raw iron and the recycled material; consistent ingredient with molten iron; purification needed;charge quality sensitive Same as cupola
