Titanium Alloy Bar And Wire Rod Rolling Process Simulation Analysis

Ti and Ti-alloy possess good combination property, which is the necessary significant material of avigation, spaceflight, shipbuilding chemical industry and biomedicine project fields and so on. It is low lumber recovery, bad quality and to adopt general 2-roll rolling, difficult to meet user's needs as a result of Ti-alloy with characteristics of bad plastic, bad thermal conductivity, high resistance to deformation, big friction coefficient. For example, Ti or Ti-alloy resistance of deformation is sensitive to temperature, while rolling this kind of difficult to deformation metal or alloy, workpiece temperature falls off and resistance to deformation augments along with rolling passes increasing, bring mill load increasing, which are not advantage to workpiece forming and affect roller operating life. The above disadvantages can be conquered by using 3-roll Y-type mill rolling and designing reasonable groove & continuous rolling technology.Following 3-roll Y-type mills are far-ranging used, groove design and parameter calculation on 3-roll y-type continuous rolling mill have became especial important. For a long time, groove design and parameter calculation dependent on manual calculation, all parameters must be recounted if preferences is not suitable, so manual calculation efficiency is low, and not advantage of groove design and change. In the interest of convenient for flexible production and for roller groove design and parameter calculation, carry through discussion on groove design with 3-roll Y-type tandem rolling, which was developed by Taiyuan University of Science and Technology, and exploit corresponding parameter calculation interface.In addition, as a result of Ti-alloy being with bad plasticity, bad thermal conductivity and high resistance to deformation and so on, higher requirement to rolling equipment driving, roller material and heat treatment mode greatly increased the cost of equipment design and production. for the sake of enhancing groove share and reducing equipment cost, carry through analysis of thermal- mechanical coupling to rolling Ti-alloy wire-rod used 3-roll Y-type mills, and simulate to fix the rolling range for the same suit of grooves using MSC.MARC software. on the one hand, simulation results have definite theoretical and practical signification, which can use as reference for equipment design, and as guidance for production practice.
