65 results about "Wrought iron" patented technology

Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name wrought because it was hammered, rolled or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild or low carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching.

Row marker used for various fields, guaranteeing straight movement, and having convenience in fertilization and carriage

The invention provides a row marker used for various fields, guaranteeing straight movement, and having convenience in fertilization and carriage, belongs to the technical field of row markers for marking positions of rows for paving a mulching film before cultivation on fields. The invention solves the following technical problems: in the prior art, a track drawn by a row marker is liable to bend, and the row marker is inconvenience and unscientific when being used for adjusting distances between rows, and cannot help fertilization and is inconvenient to carry. According to the technical scheme, positions of square tubes are controlled through different designs of round holes in two surfaces of a horizontal square tube, so that the row marker can fit row marking in two specifications. A triangle iron and a hexagonal wrought iron plate in the middle part of a mulching film can mark shallow rows and deep rows, which are beneficial to fertilization. Distance between wheels, which have flat and wide rims, and the horizontal square tube is increased under connection of an octa-hole square tube and a wrought iron plate and is regulated by the octa-hole square tube. The wheels are contacted with ground so as to guarantee straight movement of the row marker, and the row marker is convenient to push and carry; rubber sleeves with grooves are arranged at a handle top end and a position at 60-70 cm down from the top end of a long tube, so that the row marker is convenient to hold. The end portion of the long tube is rectangular in shape. A middle drill hole is fixed on the horizontal square tube. A red outer ring is additionally arranged on the head of a bolt.
