Problems solved by technology
The cast iron radiator produced by the casting process has a long service life, but the surface is rough and the internal structure is poor. Due to the limitation of the production process, the length of the radiator is limited and cannot meet the current heating demand
Steel, aluminum, magnesium alloy and other welded radiators have poor corrosion resistance and short service life. Copper radiators have very good performance, but they are rarely used due to their high cost.

Embodiment Construction
[0015] Such as Figure 1 to Figure 4 As shown, the super-long cast iron radiator of the present invention, the malleable cast iron blade and the centrifugal ductile iron pipe are connected by interference fit, the malleable cast iron blade has a hollow pipe inside, and the malleable iron blade hollow pipe is connected with a water joint and one or more centrifugal ductile iron pipe joints , The outlet of the hollow pipe of the centrifugal ductile iron pipe joint has a 20° chamfer, the two ends of the centrifugal ductile iron pipe have inward T-steps on the outer circumference, the port has a 20° chamfer, the T-step interface has a 20° chamfer, and the T-step There is a circular groove on it, which is perpendicular to the center line of the centrifugal ductile iron pipe.
[0016] Manufacture the required malleable cast iron blades and centrifugal ductile iron pipes according to the external dimensions and process requirements of the radiator and the structural dimensions and proce...

The invention relates to the field of heating, in particular to an overlength cast-iron radiator and a preparation method thereof. Two malleable cast iron piece heads are in interference fit with one or more centrifugal ball graphite cast iron pipes. O-shaped rubber seal rings are placed into circular grooves in the centrifugal ball graphite cast iron pipes, and then a hydraulic device presses the two ends of each centrifugal ball graphite cast iron pipe in centrifugal ball graphite cast iron pipe connectors of the two malleable cast iron piece heads. The overlength cast-iron radiator solves the problems that in an existing cast-iron radiator production process, solid and gaseous pollutant is discharged too much and the length is limited; radiators made of steel, aluminum and magnesium alloy are high in energy consumption and short in service life; radiators made of copper are high in cost. Produced products has the advantages of being smooth and clean in surfaces, corrosion resistant, high in pressure bearing, low in cost and long in service life.
Description
Technical field [0001] The invention relates to the field of heating, in particular to an ultra-long cast iron radiator and a manufacturing method thereof. Background technique [0002] Currently, in the field of heating radiators for civil buildings, one-piece cast iron radiators and welded radiators such as steel, aluminum, and magnesium are usually used. The cast iron radiator produced by the casting process has a long service life, but the surface is rough and the internal structure is poor. The length of the radiator is limited by the production process and cannot meet the current heating demand. Steel, aluminum, and magnesium alloy welded radiators have poor corrosion resistance and short service life. Copper radiators have very good performances, but they are rarely used due to high costs. Summary of the invention [0003] The technical problem to be solved by the present invention is: how to overcome the above-mentioned shortcomings of the prior art, and provide a radiato...
