The invention discloses a method for controlling the direction of a solidification structure of a cast ingot through electricity conductive crystallizer electroslag remelting and belongs to the technical field of metallurgy. The method comprises the steps that (1) a slag material with the high conductivity is prepared and then baked; (2) the filling rate and the insertion depth of an electrode are determined, and a base wad, an arc striking agent and an electricity conductive crystallizer are right placed; and (3) a path of an electric current flowing through a power source, the consumable electrode, the slag material, a bottom water tank and the power source is selected, and arc striking, material charging and slag melting are conducted; after the slag material is melted down, a remelting electric current and the remelting voltage are set; the path of the electric current is set through closing of a switch in the electroslag remelting process, the distribution ratio of electric currents flowing through the crystallizer and the bottom water tank is controlled, the shape and the depth of a metallic molten pool are changed, and the direction of the solidification structure is controlled; and in the later period of remelting, electricity is cut off after electroslag remelting feeding operation, cooling is conducted, and the remelted cast ingot is obtained. According to the method for controlling the direction of the solidification structure of the cast ingot through electricity conductive crystallizer electroslag remelting, a slag system with the high conductivity distribution ratio is adopted, and the tendency of axial crystallization of the solidification structure of the cast ingot is improved; and the crystallization direction of the solidification structure of the cast ingot is controlled in the remelting process, and the prepared cast ingot has good surface quality.

The invention relates to a heating easy-cut piece for a riser of a large-scale steel casting. The diameter of the riser, the angle between the upper groove and the upper surface of the fracture is 135-150 degrees, the angle between the lower groove and the lower surface of the fracture is 120-150 degrees, and the height of the lower groove from the surface of the casting is The thickness of the easy-cut sheet is 1 / 5-1 / 4, and the thickness of the fracture is 1 / 5-1 / 4 of the thickness of the easy-cut sheet; the heating rod is located on the contact surface between the upper bevel and the riser, and is perpendicular to the upper surface of the casting. . The heating rod is an iron-chromium-aluminum electric heating alloy heating rod, which is located on the inside where the contact surface between the upper bevel and the riser is perpendicular to the upper surface of the casting, and can be reused. Due to the use of specially designed easy-to-cut pieces and heating technology, the diameter of the riser neck can be greatly reduced, making the riser section smaller and easier to cut.

The invention provides a production device for large-scale high-purity and high-density oxygen-free copper ingots applied to targets. The device includes a lifting mechanism. During the production process of oxygen-free copper ingots, after the raw copper is melted, the lifting mechanism can drive The intermediate frequency coil, insulation layer and air-cooling components move upward to realize the directional solidification of copper liquid from bottom to top. During the solidification process of molten copper, since the cooling mechanism is below the crucible assembly, and the air cooling assembly moves slowly and uniformly from bottom to top, the molten copper starts to solidify from the bottom of the crucible, the bottom of the crucible is solid copper, and the upper part is un The cooled liquid copper has the phenomenon that solid and liquid exist at the same time, ensuring that there is always liquid copper on the surface of solid copper or copper that is being solidified. When defects such as holes occur in the solid copper at the bottom, the copper liquid on the upper part can be replenished in time. To achieve the effect of shrinkage, reduce the internal defects of copper ingots, increase the density of copper ingots, and obtain oxygen-free copper ingots with high purity, high density, large size and small defects.

The invention relates to the technical field of cable recycling, and discloses a cable recycling and peeling auxiliary device used in intelligent transportation projects. There is a pumping device, the left side of the pumping device is provided with a solenoid valve, the front of the sub-board is interactively connected with a movable plate, a spring tube is arranged between the movable plate and the pumping device, and a spring rod is arranged on the right side of the movable plate , the upper part of the movable plate is provided with a connecting rod extending to the sub-plate. The auxiliary device for cable recovery and peeling used in intelligent transportation projects uses a pump to inflate the spring tube to move the movable plate, which in turn causes the ring knife to cut the cable, and cooperates with the movable plate to drive the spring rod into the groove. When the solenoid valve is activated, the spring tube 2 will extend to make the ring knife pull down the cable, and then cooperate with the nozzle to spray paint to remove the residue, so as to achieve the effect of quick peeling and removal of residue.
