Abstract:
A wire rod rolling line in which the rear stages of a group of finishing rolling mills are formed by the combination of a plurality of 4-roll mills and which is extremely high in operation rate, capable of expanding the size free rolling area and forming a path schedule in which an upstream path schedule is simplified is formed so as to shorten a line stop time for mill adjustment, characterized in that the last three units of mills of the group of the finishing rolling mills are the 4-rolling mills, these three units of mills are arranged in series with their rolling down direction shifted by 45 DEG , and the last two mills are driven by a common motor and driven separately from the 3rd 4-roll mill as counted from the last stage.
Abstract:
A methods and an apparatus 10 for continuously producing steel intermediate products are disclosed. Liquid steel is cast into plural moulds 116 to continuously produce plural bloom strands 118 using continuous casting apparatus. Subsequently, one or more of the bloom strands is fed in-line to respective rolling mills 150 configured to hot roll the input continuously cast bloom strands to produce rolled billets.
Abstract:
A rolling mill stand and related rolling mill for rolling rod-shaped bodies, even large in size, which meets the requirement of stiffness uniformity of the rolling mill stands in the transversal direction, all the hydraulic capsules being firmly fixed to the external structure of the rolling mill and providing for the side change of the rolls of each stand. The arrangement of rolling rolls and related extensions of each rolling mill stand is such to avoid problems of corrosion and damaging to the extensions themselves and to the reducers due to the drainage of the cooling waters.
Abstract:
A method and an apparatus for producing a Keystone type superconducting formed strand, in which the side face of formed strands on the thinner side touches a roll ahead of the side face on the thicker side when a wire formed by stranding a large number of superconducting wires is formed using the roll. A roll abutting against the side face of the formed strands on the thicker side has a smaller diameter than that of a roll abutting against the side face on the thinner side. Furthermore, a roll shaft abutting against the side face of formed strands on the thicker side is located in the rear of a roll shaft abutting against the side face on the thinner side.
Abstract:
A composite metal article (558) from two dissimilar metals is prepared. A metal base (510) is comprised of a first metal and having first and second opposing surfaces and a lest one longitudinally-positioned depression (530,535)in each if the first and second opposing surfaces fur receiving a wire (520,525). An elongated metal element (520,525) comprised of a second metal is introduced into each of the at least one first and second depressions (530,535) of the metal base (510) to form a composite assembly (545), and the composite assembly (545) is heated under pressure to urge the adjacent surfaces of the second metal elements (520,525) and the depressions (530,535) together to form a bonded article (558).
Abstract:
The objective of the invention is, in the forming of a cylindrical pipe (60) into an angular pipe (70), to manufacture an angular pipe (70) in small volumes and with high efficiency correspondent to the variety of angular pipes demanded. This invention is configured from a plurality of horizontal forming roll pairs (na, nb) and a plurality of vertical forming roll pairs (nc, nd) arranged alternately in the direction of travel (HL) of the cylindrical pipe (60), and a configuration is further adopted in which the forming rolls are divided into several groups and incorporated in a common support frame for each group, and, a control mechanism is employed to vary the positions of the rolls to the pipe using supporting frame units. By the employment of this roll position control mechanism the roll positions incorporated using the supporting frame units and roll gaps in the vertical and horizontal direction are altered, and by the passing through the altered roll gap and the application of the desired deformation to the desired cylindrical pipe (70) the desired angular pipe is formed. Using a configuration such as this, forming of the angular pipe (60) is achieved with high productivity with differing dimensions, as appropriate, from a cylindrical pipe of differing dimensions with no changing of the forming rolls at all.
