SUPPORTS OF CAST IRON TO OUTDOOR STREET LIGHTING 1.Classification: As per application As per materials 2.Manufacturing process: Previous research. Building Moulds. Smelting pieces. Mechanize Finishing Packing/Handling. 3.General Characteristics: Differences between cast Iron/Aluminium 4.Quality control possible faults 5.Summary, comments & conclusions
SUPPORTS OF CAST IRON APPLICATION Columns Brackets MATERIALS Cast Iron. Cast Aluminium Others no ferrics
MANUFACTURING PROCESS OF CAST IRON LIGHT FITTING Previous research. Building Moulds Smelting pieces Moulding Positioning Closing boxes Fusion Rinding Fettled Mechanize Drill Winch Adjustments Finishing shotpeened Putty / finishing Primer coating Finishing coated - colour Camera de polymerisation Packing / handling.
No norm no standardization / certified Research of R. to finite parts. PREVIOUS RESEARCH
GENERAL CHARACTERISTICS OF OUTDOOR STREET LIGHTING IN CAST IRON Reproduction of forms Great similarity of pieces Section & Strongest Texture Synonymous of quality Recyclable 100% without cost raw material

CHARACTERISTICS OF CAST IRON Type EN-GJL-200 As per norm: EN 1561 Type EN-GJS-500-7 As per norm: EN 1563 Differents degrees R. of stretching. Good behavior to oxidation. –Non reduction section. - Oxide = Protection Grey cast iron (traditional) Ductile cast iron (> R)
Norm EN 1706 Many alloys according to application. Great difference of €/Kg. Acording quality Danger In “normal” alloys, porous oxide Progressive Oxidation Galvanic Par with fastening bolts & Columns. CHARACTERISTICS OF CAST ALUMINIUM
QUALITY CONTROL Metallurgical quality control T hicknesses control with ultrasounds Hardness control Primer micron-size control & painting by ultrasounds Adherence control Chamber control of foggy salt Ultraviolet chamber control Effort in point control in test machine. POSSIBILITY OF FAULTS
SUMMARY, COMMENTS & CONCLUSIONS Historically, light fitting with gas were only of casting Possibility of recovering old forms Project quality Possibility of mixed lamp post + slender + economic Cast iron Lamp post - Progression of oxidation - Galvanic Par Brackets of cast aluminium, thickness 1/3 Columns no approved Pay attention to the quality Are hte supports “for all the life” Sevilla, supports catenary tram with outdoor street lighting Sculptures up to 8 Tn. Differents pieces not catalogued Class I. to control gear is essential earth wire.
