Technology Innovation cast iron radiator

Industry Invention/Large Scale Automatic Sand Core Production Equipment
In order to realize the cast iron radiator with no sands inside, Beizhu radiators invested a lot of manpower and material resources to the research of years and repetitions test, finally successfully made the first large scale automatic sand core production equipment in the industry, totally changed the history of man-made sand core. It promoted the cast iron radiators to the new era of no sands, and brought a new world to the cast iron radiator.
Compared to the 1st generation cast iron radiators with sand core and the 2nd generation Man-made cast iron radiators with Furan Resins sand core, the radiators without sands inside produced by the 3rd generation sand core production equipment made a great progress in the aspects of technical characteristic, production process, heating efficiency and energy saving. The 3rd generation products' reputation comes naturally from real distinction.
The cores of Beizhu the 3rd Generation Cast Iron Radiators are made by Automatic Core Shooters. The Automatic Core Shooter mix the phenol-formaldehyde resin and 70-140 mesh number drying white sands evenly, then the high tension shooting mouth of  Automatic Core Shooter shoot the mixture to the core model at the speed of 20 metres/s. Then it will be shaped by stereo heating, and the shaped core with smooth both inside face and outside face can stand the tension of 25kg/cm3 . There is no residual iron on the core, realizing real core without sands.
Technology Innovation/ Substantially Increase Heating Efficiency
The sand core made by the Automatic Core Shooters has high mesh size and huge overall strength with smooth face and convex face will be more even. The sands inside the radiator core has good collapsibility and can be cleaned totally, realizing core without sands, thickness of radiator tube wall more even, inside face of core more smooth. It is a breakthrough revolution in the cast iron radiator industry depending on the most advanced technology in domestic industry. In front of the same heat medium, compared to the one man-made, the heat medium fluid in the sand core made be automatic core shooter meet less resistance and has faster fluid speed and more heat extraction.
Energy Saving/Modern Heating
The materials of the 3rd Generation Cast Iron Radiators are mixed with rare earth and Manganese alloy which can increase its mechanical properties. It is different from the traditional cast iron, it has been malleable iron with excellent strength and tenacity. The working pressure of radiator can reach 10kg/cm3 which is higher than it of the traditional one 8kg/cm3, and it can meet the heating needs of high rises and ultra high rises. The inner face and outside face of malleable iron radiators are smooth and can resist compression. The tube wall is 0.15mm thicker than it of the traditional cast iron radiators. The pressure increases 2kg/cm3. With faster speed and higher efficiency, the new radiators are energy saving and environment friendly.
