Abstract: The examples described herein provide methods and equipment for an anti-oxidation spraying on a steel billet. In some examples, when the billet at the temperature of 400° C.-1000° C. enters the predetermined spraying region, a plurality of anti-oxidation spraying devices are used to perform an anti-oxidation spray on the billet in two or more directions, thereby forming directly an anti-oxidation coating on the steel billet at 400° C.-1000° C. By using the example method and equipment described herein, on-line spraying of anti-oxidation coating on the steel billet can be performed under high-temperature condition, thereby reducing an oxidation burning loss rate of the steel billet.

Abstract: The present disclosure relates to an antioxidation coating for steel. In one example, the coating is produced by mixing magnesian mineral, layered silicate, metallurgical solid waste, aluminum powder, organic thickener and inorganic binder including the components of Al2O3, SiO2, MgO, CaO, Fe2O3 or the like with water, and the final coating density is adjusted to 1,100˜1,500 kg/m3 by adding water.

Abstract: The invention provides a sucker structure comprising a sucker body made from flexible materials including a base portion having a central blind hole being of a T-shaped cross-section; a rim portion having an annular projection, a recess and a flat outmost edge; and a declining intermediate portion connected between the base portion and the rim portion, wherein the recess is located between the projection and the declining intermediate portion; a supporting disk including an annular edge portion comprising a first annular groove for engaging the annular projection of the sucker body therein and a second annular groove outside of the first annular groove; a sealing filler engaged with the semi-circular groove; a threaded rod including a rod body with a male thread thereon and an flange at one end thereof, wherein the flange is inserted into the central blind hole of the base portion of the sucker body and formed as an integral with the sucker body; and an adjusting nut member engaged with the threaded rod by a

Abstract: A chuck for holding a small bit and used with a table drill is provided for drilling a millipore. The chuck includes a holding jaw having four holders; a jaw-positioning guiding body with a square hole at the front portion for positioning the holding jaw; a crossing linkage for connecting the body to the jaw and having a crossing head and a projection portion between which a groove is formed; a guiding jacket matched with the crossing linkage and the body; a positioning screw nut matched with the jaw-position guiding body; a screw collar matched with the crossing linkage; and a bevel gear housing housed around the screw collar for adjusting the position of the holding jaw.
