Sand casting ductile iron bridge guardrail support
The sand casting ductile iron bridge guardrail bracket is an isolation ductile iron casting components used to block both sides along the bridge. And the anti-collision bridge guardrail supprot is to prevent out-of-control vehicles from crossing the bridge, which has the functions of preventing vehicles from breaking through, corssing, crossing bridges and beautifying bridge buildings.
Bridge guardrail brackets can be divided into three types according to the process: welded guardrail brackets, cast iron guardrail brackets, and stainless steel brackets. Welded brackets have a beautiful appearance and high tensile strength, and hot-dip galvanizing is used for anti-corrosion to ensure product life. The surface is sprayed with plastic according to the color required by the user. Cast iron brackets are mainly corrosion-resistant and have a long service life, while stainless steel brackets are made of 304 material. DC welding and sub arc welding have a beautiful appearance and a long service life, but the cost is relatively high. Generally, the first two are more commonly used! Production process: The production and manufacturing process of steel plate welding brackets is accurate and can be produced according to the design requirements of different drawings. At the same time, the appearance dimensions of the product are consistent with the design requirements of the drawings, and the appearance is beautiful, which can meet the requirements of municipal and highway landscape design. It can be produced according to the design requirements of different drawings, and the appearance dimensions of the product are consistent with the design requirements of the drawings, and the appearance is beautiful.
Ductile cast iron grades
Ductile cast iron: ASTM A536 refer to the standard specification for ductile iron castings. Baoding Guokun, a China sand casting factory, can manufacture various pumps, valves, agriculture parts, motor castings, railway castings, marine castings and other engineering casting components in several grades of ductile iron, including:
ASTM A536 Grade 60-40-18 is a nodular iron with a mostly ferritic microstructure and mechanical properties comparable to low alloy steels.
ASTM A536 Grade 65-45-12 is a nodular iron with a ferritic and pearlitic microstructure and mechanical properties comparable to low alloy steels.
ASTM A536 Grade 80-55-06, relating standards SAE J434C D5506 or ISO 1083 500-7, is a nodular iron with mostly pearlitic and smaller amount of ferrite microstructure.
ASTM A536 Grade 100-70-03, named pearlitic ductile iron, includes graphite spheroids in a matrix of pearlite. The pearlite matrix is comparatively hard and has high strength, combined with good wear resistance. This is combined with average ductility and impact resistance.
ASTM A536 Grade 120-90-02, named Martensitic ductile iron, has low to zero pearlite formation due to specific alloy additions, and can be quite hard and brittle in its untampered form.
Sand Casting process, resin sand casting, green sand casting, precoated sand casting, shell mold casting process
Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages. Baoding Guokun can produce various sand cast parts in cast iron, ductile iron, gray iron, low-carbon steel, mild steel, alloy steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.
The process of Baoding Guokun sand casting involves several steps after producing a professional tool or mold, including:
| No. | Steps | Details |
| 1 | Pattern Creation | A two-piece metal pattern is created in the shape of the desired part, typically from iron, aluminum or wooden material.For a single casting or small batches of castings, we prefer to produce to use the wooden material to manufacture the mold to save money for customers.For other sand casting parts in large quantity, we prefer to use aluminum or iron to improve the mold’s service life. |
| 2 | Mold creation | The two shell halves are joined together and securely clamped to form the complete shell mold. If any cores are required, they are inserted prior to closing the mold. The shell mold is then placed into a flask and supported by a backing material. |
| 3 | Pouring | The mold is securely clamped together while the molten metal is poured from a ladle into the gating system and fills the mold cavity. |
| 4 | Cooling | After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final castings. |
| 5 | Raw Castings | After the molten metal has cooled, the mold can be broken and the casting removed. Trimming and cleaning processes are required to remove any excess metal from the feed system and any sand from the mold |
| 6 | Machining | Machining as per drawings |
