Detailed description of the invention
The invention provides a kind of continuous rolling technology of titanium or titanium alloy, comprise the following steps:
A, charging: titanium or titan alloy casting ingot are transported on the discharging track in induction heater;
B, heating: when being transported to when titanium or titan alloy casting ingot on the discharging track in induction heater, utilize electromagnetic induction to heat titanium or titan alloy casting ingot by carrying out energising to induction heater;
C, insulation conveying: the pure titanium heated in step a or titan alloy casting ingot are transported in rolling unit from induction heater under the state of insulation;
D, rolling: utilize rolling unit in step b insulation conveying come in pure titanium or titan alloy casting ingot carry out continuous rolling;
E, discharging: material continuous rolling completed by guide wheel assembly is transported in skid bed from rolling unit.
Rolling unit described in above-mentioned continuous rolling technology is six frame Y type rolling units, and six described frame Y type rolling units are made up of bar continuous rolling unit and sheet material continuous rolling unit again.
The circle obtained through continuous casting and flat ingot casting are sent in induction heater by the present invention, by inductive loop, ingot casting is heated, then under the state of insulation the ingot casting after heated by induction heater out after by driven roller, ingot casting is sent into six frame y-type rolling mills before niproll, ingot casting is rolled by technological requirement.The roll of y-type rolling mill can be determined according to the shape of ingot casting, expect by last frame of y-type rolling mill out after, by guide wheel assembly, material is sent in skid bed, so just completes the work of tandem rolling.The design adopts the holding furnace of eddy-current heating and the combination of Y type roll mill unit, realizes carrying out smoothly of continuous rolling, and can realize the rolling of rod, sheet material; And thinner titanium or titanium alloy wire rod can be rolled out by the frame quantity changing or increase unit to the roll of six frame y-type rolling mills.
