Description
Technical field
The present invention relates to rolling technical field, particularly a kind of upper transmission vertical roll mill, also relate to the roll-changing method of a kind of more efficient milling train arrangement and vertical miller simultaneously.
Background technology
The vertical miller of cut deal, steekle mill, hot continuous rolling and (or) band steel engineering is used for the rolling in width of plate slab direction, and its roll driving type is divided into upper driving and underdrive two kinds of forms.The transmission device of upper transmission vertical roll mill is placed in above standing roller frame, by the universal-joint spindle dummy roll vertically arranged; Upper transmission vertical roll mill organic frame is fixing shifts out two kinds of roll change forms with frame, and concrete roll change process is as follows:
One, the roller replacing mode of the fixed upper driving of frame:
1, by side shifter, roll assembling is moved on to the spindle carrier position of standing roller frame transmission side or fore side;
2, the flat head sleeve of universal-joint spindle upwards holds up by spindle carrier, roll is assembled and is separated with the flat head sleeve of universal-joint spindle;
3, oppositely roll assembling is moved on to the roll change lifting position in the middle part of standing roller frame by side shifter;
4, from vertical miller entrance side or outlet side ship suspender sling roll assembling, make roll assemble depart from standing roller frame;
5, after roll assembling departs from standing roller frame, suspender, along the outwards movement of roll line direction, makes roll assemble and hangs away from vertical miller entrance side or outlet side;
6, new roll assembling loads standing roller frame by above-mentioned order on the contrary, completes roll change.
Two, the roller replacing mode of frame moving-out type upper driving:
1, by side shifter, roll assembling is moved on to spindle carrier position;
2, the flat head sleeve of universal-joint spindle upwards holds up by spindle carrier, roll is assembled and is separated with the flat head sleeve of universal-joint spindle;
3, by shift-out mechanism, the standing roller frame entirety that roll assembling is housed is moved out to outside roll line;
4, remove old roll outward at roll line assemble and load new roll assembling;
5, oppositely the standing roller frame entirety that new roller is housed is moved back on roll line by shift-out mechanism, completes roll change.
Visible, the fixed roll change of frame needs have enough roll change spaces to realize roll change at the entrance side of vertical miller or outlet side along roll line direction; The roll change of frame moving-out type does not take the space in roll line direction, but shifts out the relative fixed frame of gantry base and take up room greatly, causes spacing between vertical miller and front and back equipment larger.
Some special steel need of production horizontal mill and vertical miller are alternately arranged, as band steel workshop adopts the reversible rolling finishing mill of 5 frame, horizontal mill adopts four-high mill, and 5 frames are that Ping Lipingli plain cloth is put, and require that frame spacing is very compact, with the product quality obtained.Under this compact Layout requires, if vertical miller adopts underdrive pattern, it is no problem that the reversible tandem rolling of multi-frame realizes compact Layout, but lower-drive type vertical miller is not accepted by Most users because of the reason such as difficult in maintenance; Upload dynamic formula vertical miller according to traditional, because frame spacing is very compact, edger roll roll change cannot realize roll change (unless strengthening frame spacing) with traditional roller replacing mode.
