High Level Metal Seamless Pure Calcium Cored Wire

A production method of seamless pure calcium cored wire, which belongs to the technical field of alloy cored wire. The production method of the present invention comprises the following steps: after heating a metal calcium rod, it is extruded into a metal calcium wire with a diameter of 8.712.9mm through an extruder; The extruded metal calcium wire is introduced into the vacuum coating treatment tank, so that the surface of the calcium wire is uniformly coated with nano-ceramic coating; The calcium filament coated with nano-ceramic coating is introduced into the curing processor and cured by a hot air device. After the surface coating of the metal calcium wire is cured, it is introduced into the sizing machine for sizing treatment through the guide wheel, and then the excess coating on the surface of the calcium wire is cut off and rewound into a seamless pure calcium cored wire with a diameter of 913mm. The technical scheme of the present invention can effectively guarantee the treatment effect of the obtained cored wire to the molten steel, and the rejection rate of the obtained cored wire product is low, and its production system structure is simple, the production efficiency is high, the cost is low, and it is convenient to popularize and use.

1.a pure calcium cored wire comprises a wire core barrel, the inside of the core barrel is provided with a cored wire, the outer surface of the core barrel is provided with a connecting layer, the outer surface of the connecting layer is provided with a buffer layer, and the outer surface of the buffer layer is provided with an inner cladding layer; the protective groove is formed in the inside of the connecting layer, the wire core barrel is installed in the inside of the connecting layer, and the inner side wall of the connecting layer is provided with a first fastening ring. The utility model discloses a stable installation on the outer surface of the inner cladding layer through a fastening ring, and in the inside of the stabilizing cylinder, the screwing column is twisted before use, through the adaptation between the screwing column and the mounting thread, the contradicting spring is pressed downward, when the countering cylinder is against the top surface of the inner cladding, the screwing column begins to continue to press downward, thereby the resisting cylinder is squeezed by the elastic force of the contradicting spring, and the inner cladding layer is more stable in the inside of the fastening ring, and the problem that the cored wire protection can only be only in the inside in the past has been solved.
