The invention discloses a production method for an iron furnace
slag light building block. A formula of the iron furnace
slag light building block comprises iron furnace
slag,
chimney ash,
perlite and
cement which form dry blend; every
ton of dry blend is mixed with
polystyrene particles, water and various additives; a production
system consists of hoppers, a stock bin, a
polystyrene granule extruder, electronic scales, a scraper conveyer, a water pump, a stirrer, a mould
assembly, a
light rail and various additive bins. The production
system is characterized in that the outlet of each hopper and the outlet of each bin are equipped with the electronic scale controlled by a computer, and each electronic scale is in
butt joint with the scraper conveyor; the scraper conveyor is connected with a feed end of the stirrer; an outlet of a
polystyrene granule bin is connected with the stirrer; the extruder is connected with a steam
pipe; the stirrer is connected with a water outlet tube of the water pump; a mould car is arranged on the
light rail; the mould
assembly is arranged on the mould car, and is in
butt joint with the outlet of the stirrer; and a mould is filled with a wet mixture for moulding, the wet mixture is manually de-molded, and is maintained by applying water. According to the production method disclosed by the invention, waste can be changed into things of value, and the formula is non-toxic, flavorless and free of
radioactive contamination, and therefore, the iron furnace slag light building block is a pure natural, green, healthy and
ecological environment-friendly wall.
