Description
Technical field
The utility model relates to a kind of metallurgy industry steel rolling equipment, is specifically related to a kind of minor diameter spinneret for high speed special steel wire production.
Background technology
Special steel (stainless steel, high-speed steel) from straight carbon steel because the content of phosphorus content and metallic element is different, so require completely different on rolling mill practice.The temperature of the operation of rolling controls to be directly connected to the metallurgical structure of institute's rolled material and the mechanical performance of material, has conclusive effect with whether every quality of material is qualified.Determine straight carbon steel thus to adopt when rolling and large tell loop diameter, after Tu Quan completes, adopt air-cooled air cooling roller-way to cool, rear direct collecting and baling completes, and namely becomes final products.But the rolling of special steel and straight carbon steel have very large difference.Except the temperature-control pressure-control rolling in finish rolling district, after end of weaving silk, there are the slow cooling being different from straight carbon steel of its uniqueness, Technology for Heating Processing.In order to meet material metallographic structure and the mechanical performance of special steel.After Tu Quan terminates, do not carry out air cooling, air-cooled, but silk volume is twisted in a kind of special pot type gathering-device by long-pending, then carry out special salt bath heat treatment.The Equipment for Heating Processing of this pot type gathering-device and producer is supporting, so collecting tank has size to limit.What this required to weave silk rolling wire rod tells the dimensional requirement that loop diameter will meet this gathering-device.Straight carbon steel Laying head tell that loop diameter is now domestic to be generally
tell loop diameter bigger than normal, the equipment requirement of some special steel manufacturer can not be met.Loop diameter large is told to cater to by steel mill thus, usually can cause the waste of part existing device or the equipment reinvestment of high cost.Main cause is that spinneret is space three-dimensional curve, and Design and manufacture difficulty is large.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind ofly special steel wire rod can be made to meet in the operation of rolling specially tell loop diameter requirement and to weave silk the little minor diameter spinneret for high speed special steel wire production of rolling wire rod.
For achieving the above object, the technical solution adopted in the utility model is: comprise initial segment 1, deformation section and setting section, and described initial segment is straightway, and the spiral angle of deformation section is 320 °, and radius of curvature R is 0-380, and setting section spiral angle is 50 °.
The axial length of described initial segment is 192mm.
The axial length of described deformation section is 1571.8mm.
The axial length of described setting section is 17.7mm.
The length of each section of the utility model and curvature all can impact for all the other length of each section and curvature, although tell the radius of curvature R that loop diameter finally depends on setting section, but itself and initial segment and deformation section have strict relation, the size of telling loop diameter finally depends on the radius of curvature of setting section, the minimum one-tenth loop diameter of this spinneret is 760mm, and this is because the radius of curvature R of spinneret setting section is 380mm.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.
See Fig. 1,2, the utility model overall length is 1781.5mm.Comprise initial segment 1, deformation section 2 and setting section 3.Initial segment (straightway) axial length is 192mm, does not have spiral angle.Deformation section 2 (axial length) is 1571.8mm, and spiral angle is 320 ° (0-320 °), and radius of curvature R is by 0-380.Setting section 3 axial length is 17.7mm, but its winding angle (spiral angle) is 50 ° (320 °-370 °).Three sections of parameters of curve of spinneret form according to wire rod rolling forming principle design optimization.The length of each section and curvature all can impact for all the other length of each section and curvature, therefore choose reasonable should enclose conclusive effect for being deformed into of wire rod when designing.Although tell the radius of curvature R that loop diameter finally depends on setting section, but itself and initial segment and deformation section have strict relation, the size of telling loop diameter finally depends on the radius of curvature of setting section, the minimum one-tenth loop diameter of this spinneret is 760mm, and this is because the radius of curvature R of spinneret setting section is 380mm.This designs according to the particular/special requirement of producer.
The minor diameter spinneret diameter that the utility model is used for high speed special steel (stainless steel, high-speed steel) wire production is
by the redesign of telling loop diameter and dish distance (being equivalent to the pitch of screw thread) to spinneret, optimization.Long-pending be rolled on the benchmark of circle meeting normally weaving silk of special steel wire rod, meet the particular/special requirement for minor diameter wire rod Tu Quan in special steel wire rod rolling process.Avoid the waste of steel mill for existing device and the reinvestment of equipment, save production cost.Simultaneously also for the small size Design and manufacture of spinneret provides experience, have accumulated technical data.
Spinneret of the present utility model comprises three sections: initial segment, deformation section, setting section.List is sayed from shape-designing, and spinneret diameter seems infinitely to reduce.So that become straight line.But from the shaping Tu Quan of steel, the diameter of spinneret can not be too small, and three sections of sizes have strict curvature requirement.Curvature is too small then cannot by steel bending lopping, excessive, steel frictional force when the inner relative sliding of spinneret can be made to strengthen, will increase the power output of Laying head and reduce the service life of spinneret.Also the effect of Laying head lopping will be affected.For this reason when three-dimensional modeling, we are according to technological requirement when designing requirement and special steel rolling, and choose reasonable is optimized spinneret each section of curvature and controlled each section of length of a curve.Design and littlely tell loop diameter to novel
spinneret.Met the steel rolling process requirement of special steel completely by practice test, effect of weaving silk is fine.
During special steel rolling, the laying head of this spinneret and Laying head is rotated and assembles, by the rotation of laying head, drive the revolution of spinneret.The steel come by straight line utilize the conglobate Tu Quan of spinneret rotary bending, realize the lopping of weaving silk of steel.Minor diameter spinneret of the present utility model makes the circle forming diameter of telling of wire rod tell loop diameter than straight carbon steel and be greatly decreased to
meet the little heat treatment requirements telling loop diameter that special steel wire rod is special after Tu Quan.Meet the instructions for use of collecting tank and associated hot handling implement.
