A grid plate for a lead acid storage battery comprising a frame section having a pair of quadrangular contour shape, and longitudinal grid strands and lateral grid strands that form a grid inside the frame section. The longitudinal grid strands and lateral grid strands are composed of thick strands of smaller thickness than the frame section, and thin strands of smaller width and thickness than the thick strands. The thick strands and thin strands are arranged so that the strands adjacent to the thick strands are thin strands, and space is reliably provided for facilitating the flow of active material to the sides of the thick strands. The two ends of the thick strands in the thickness direction are positioned further inward from the two end faces of the frame section in the thickness direction, and the end portions of one end side of the thin strands in the thickness direction are positioned in positions offset to one end side of the thick strands in the thickness direction, whereby the active material is readily packed into the reverse surface side of the grid plate.

The invention relates to the technical field of manufacture of plastic products, in particular to a patterning process for a rotationally-molded product. The process is based on a rotational molding process, and comprises the following steps of: attaching a layer of colored solvent to a part to be patterned according to the shape and size of a pattern in a mold, closing the mold, feeding raw materials for producing the rotationally-molded product, and patterning the rotationally-molded product by using the rotational molding process to integrate the colored solvent with the rotationally-molded product.

The invention provides a solar thermal collector. The solar thermal collector comprises two tube plate structures, wherein a certain included angle is formed between the two tube plate structures; the direction of the included angle is opposite to the bending direction of an arc structure of a reflecting mirror; the focus of the reflecting mirror is in the included angle formed by the tube plate structures; inner fins are arranged inside collector tubes, are connected with opposite angles of rectangles and divide the interiors of the collector tubes into a plurality of small channels; communication pores are formed in the inner fins; the flows of fluids in different collector tubes are larger and larger in the extension directions from the collection point of the two tube plate structures to the lowest positions at the two sides. The solar thermal collector has the advantages that the uniform mixedness of fluids is maintained, thus avoiding loss of heat during fluid mixing; the temperatures of the collector tubes are ensured to basically keep the same, thus prolonging the overall service lives of the collector tubes.

The invention discloses a method for manufacturing a steel ingot used for million-kilowatt nuclear power reactor core structural component, austenitic stainless steel ingot that weighs over 25 tons is manufactured by electroslag remelting process: firstly, preparation: a single-phase bipolar series connected or triphase bipolar series connected electroslag remelting furnace is adopted; a copper wall water-cooling crystallizer and a water-cooled base plate are adopted; a consumable electrode is assembled; slag charge is matched; SiGa and Al powder are adopted for deoxidation; secondly, refinement and fusion casting: a graphite electrode is picked up and replaced by the consumable electrode to remelt the fully melted slag charge after slagging and slugging. When the actual weight of the steel ingot is 2 tons less than the preset weight, the electric power is reduced and feeding operation in telophase is carried out; thirdly, the steel ingot is stripped. The steel ingot manufactured by the invention has extremely high purity, extremely fine uniformity, excellent high temperature resistance and tarnish resistance, as well as strong anti neutron radiation embrittlement sensibility.
