This invention provides a method for controlling the uniformity of quenching cooling in intensive continuous heat treatment of hot coils, comprising the following steps: (1) using multiple sets of pressure rollers as dividing points, the cooling zone is divided into multiple segments, with the area between two adjacent sets of pressure rollers as one segment. After the strip enters the cooling zone, the tension of each segment of the cooling zone is controlled at 5-35 MPa; (2) spraying facilities for dispensing cooling medium are set at the upper and lower parts of the strip in each segment of the cooling zone; along the width direction of the strip, the surface of the strip is divided into 3-7 zones, with the middle zone as the central zone and the other zones as the edge zones. The air-to-water ratio of each zone is 2:6-6:2, and the flow rate ratio of the edge and central zones is 0.8:1-0.2:1.5; the flow rate ratio of the upper and lower surfaces of the strip provided by the corresponding spraying facilities is 1:2-2:1.

The present invention discloses a method for effectively improving the utilization rate of casting rolls in aluminum alloy production. The method comprises the following steps: the aluminum melt used in aluminum alloy production has a hydrogen content of ≤0.10 mL / 100 g; the casting roll is a core component of the casting mill, and has a roll diameter of ≤960 mm, a crown of ≤0.30 mm, and a casting zone length of 58 to 60 mm; the casting mill also includes a casting nozzle, the nozzle outlet of which is positioned between the casting rolls. The casting nozzle comprises a front zone, a middle zone, and a rear zone. The front zone is a flat lip zone that gradually narrows forward; the rear zone is 50 mm wide; and the middle zone is divided into several channels, wherein the width of the middle channel is 17 mm, and the widths of the channels on both sides increase by 5 mm. While ensuring that the quality of the aluminum alloy billet meets the standard, the present invention successfully increases the diameter of the casting roll to 950 mm, significantly improving the service life of the casting roll and reducing production costs.

A cover-flap transfer tape construct and associated applicators for paper web turn-up are disclosed. A zone-coated substrate carried on a linered web includes a top-side central web-grabbing adhesive band bounded by uncoated edge zones, and underside edge mounting adhesive bands separated by an uncoated middle zone. An applicator forms an out-of-plane raised profile across a central portion of the tape while maintaining planar side bands, using cooperating forming members (convex crest and complementary cavity) and manual or motorized feed. The formed length is cut to yield a discrete tape construct with the raised profile over the central adhesive and side bands aligned with mounting adhesives. The tape construct promotes reliable interception and transfer of a moving paper web during turn-up.

The application discloses a CSAMT full-area apparent resistivity-depth profile generation method. The horizontal position and vertical position of a recording point are taken as the assignment points of the apparent resistivity; in the far zone, the recording point is located at the detection depth directly below the measuring point; in the middle zone, the radius of the wave front is linearly reduced with the decrease of the induction number, the recording point is located at the intersection of the wave front and the detection depth to the source point straight line and approaches the source point from the measuring point with the decrease of the induction number; in the near zone, with the continuous decrease of the induction number, the horizontal position of the recording point approaches the midpoint of the offset distance from the vicinity of the source point, and the vertical position approaches a certain fixed value proportional to the offset distance from the vicinity below the source point, and the fixed value is equal to the offset distance divided by the critical value of the far zone and the middle zone. The application provides a new, simple, fast method for separating the plane and non-plane wave, eliminating and utilizing the field source copying and shadow effect, and improves the interpretation effect of the apparent resistivity-depth profile.
