Description
Technical field
The utility model relates to the metallurgy rolling mill device, and more particularly, the utility model relates to a kind of metallurgy rolling mill device of rolled wire.
Background technology
In the last few years, along with development of science and technology, manufacturing rise, the metal wire rod its domestic application was increasingly extensive, had also driven the manufacturing development of domestic high-speed rod simultaneously, and domestic enterprise develops and equip homemade homemade high-speed rod-rolling mill more and more; Through continuous absorption and improvement, homemade high-speed rod-rolling mill mill speed also improves constantly.
At present homemade comparatively advanced high speed wire rod finishing block group is the imitative root five generations milling train unit that rubs, and is that topcross 45 degree are arranged, 10 frame central driving; The cabinet of frame is made up of conical tooth roller box and roll-box respectively; For adapting to the changes in demand of market to different wire rods; Roll-box takes directly to insert the assembly structure of conical tooth roller box, so that quickness and high efficiency ground switches the roll-box that installation has different size, spacing and can adorn the roll mandrel group of different collars on the conical tooth roller box.
The cabinet sealing system of this type unit mainly is made up of main seal such as static seal between movable sealing, static seal, roll-box and the conical tooth roller box faying face of roll-box: the movable sealing of roll-box comprises that the outer slip ring that is adjacent to collars that roll mandrel top is adorned, interior slip ring, roll mandrel and the double-lip sealing ring etc. that are adjacent to bottom, bottom roll-box panel form; Slip ring runs up with roll mandrel during the unit running; Contact and relative motion with double-lip sealing ring, constitute movable sealing; The roll-box static seal is made up of two roller sealing plates of single roller sealing plate of double-lip sealing ring and support ring, support ring and O shape circle, single hole, the diplopore figure of eight and roll-box faying face etc.
The inventor finds according to the protracted experience analysis: frame does not have ventilator cowling; And air motion forms circulating current in the cabinet spill strip mantle generating gear case chamber; Bring air-flow in the conical tooth roller box cavity into oil return pipe; Make chamber internal gas pressure P1 be lower than casing outside atmosphere pressure P 0, produce negative pressure, negative pressure value is about about 0.1Mpa; Receive that negative pressure influences in the chamber; The chamber outer air is constantly aspirated through roll-box movable sealing (lips and slip ring contact site) and the damaged quilt of each point static seal and is got in cabinet and the conical tooth roller box chamber, and the oxide that also cooling water and the wire surface of cooling work collars is dropped is simultaneously brought in roll-box, the conical tooth roller box, and gets into lubricating system in the lump with lubricating oil; So; Gently then cause oil product serious emulsification, pollution and aging etc., the running environment of relevant visual plant is worsened, the wearing and tearing aggravation, heavy then plugged filter was lost efficacy even the obstruction atomizer; Cause oil starvation to cause the substantial equipment fault, have a strong impact on production; And the oil pollution loss is big, and spare parts such as smart filter core and bearing are short service life, and the equipment mistake product time is many, exerts heavy pressures on to plant maintenance.
For above-mentioned reasons; The air-breathing water inlet problem of the sealing system of domestic this type of mm finishing mill unit is perplexing the production of high-speed rod-rolling mill always; And the high speed wire rod finishing block group is key link and throat that high line products is produced; Product quality and output are had very important influence, and therefore, the air-breathing water inlet problem of cabinet sealing system that solves mm finishing mill unit is very urgent.
