Abstract
The present invention relates to a vertical rolling method of wide flange steel and its equipment, belonging to the field of metal rolling technology. Said method includes the following steps: billet heating, des caling, blooming, cropping and rolling so as to obtain the rolled material with web plate and flange. Said invention also provides the concrete operation steps of said rolling process.
Description
Technical field
The invention belongs to the rolling of metal, relate in particular to the milling method and the device of shaped steel.
Background technology
H shaped steel is the economic section steel, is widely used in industry, agricultural, communications and transportation and the architectural engineering.Current, the method of the rolling web of rolling employing level of H shaped steel, after the steel billet heating, through split rolling method, rolled piece with the web of H shape and edge of a wing enter again omnipotent in, mm finishing mill unit and edging mill be rolled, web is by the horizontal roll spreading attenuate of upper and lower settings, the edge of a wing by about the edger roll spreading attenuate that is provided with.The rolled piece section just is being " H " shape from start to finish, and web is in level, and the edge of a wing is in plumbness, the defective of this milling method is, in the operation of rolling, be sprayed on the roll cooling water quite a few flow in the elongated slot that constitutes by the web and the edge of a wing, can't get rid of.These cooling waters descend the temperature of rolled piece rapidly, temperature reduces, roll-force and moment are index and rise, so both increased roll-force and roll torque, the energy consumption of Rolling Production increases, and has worsened the mechanical property of steel again, strengthened rolling difficulty, especially rolling web and edge of a wing thin-wall product, some light thin wall products can't be rolling, thereby limited the application of H shaped steel.
Summary of the invention
In order to overcome the shortcomings and deficiencies that background technology exists, the purpose of this invention is to provide vertical milling method of a kind of H shaped steel and device, adopt the method for vertical rolling web, descend rapidly to reduce the temperature of rolled piece in the operation of rolling, reduce roll-force and moment, reduce the energy consumption of Rolling Production, enlarge H shaped steel product variety, specification, produce the H shaped steel steel of light thin wall more.
The vertical milling method of H shaped steel, comprise steel billet heating, de-scaling, cogging, crop, be rolled into " H " shape rolled piece with web and edge of a wing, be characterized in rolled piece enters, before the finishing mill, turn over by lifting finger and to turn 90 degrees, the rolled piece section is turned into " worker " shape with respect to roll line by " H " shape, web in vertical state, the edge of a wing is the level of state; The rolled piece that overturn enter again vertical universal mill and vertical edging mill carry out in, finish rolling, one side is rolling to rolled piece height and flange width, to the thickness spreading attenuate on web, the edge of a wing, be in plumbness at operation of rolling median ventral plate on one side, the edge of a wing is in the level; Cut off behind the rolled piece roll forming, turn over again to turn 90 degrees behind the last cold bed and cool off.
The inventive method is further improved, and depressing in the horizontal direction of web carried out, and is rolling by a pair of vertical rolls that are provided with about universal mill; The edge of a wing is depressed in vertical direction and is carried out, by a pair of horizontal roll and the vertical rolls acting in conjunction spreading of universal mill upper and lower settings.
Vertical edging mill is established a pair of vertical rolls, and flange width is controlled.
The vertical rolling device of H shaped steel comprises that heating furnace, high-pressure water descaling machine, big mill, crop device, shearing device, cold bed set gradually along roll line, and its characteristics set gradually lifting finger, vertical universal mill, vertical edging mill along roll line; Before lifting finger was located at big mill outlet, vertical universal mill, vertical universal mill and vertical edging mill were arranged alternately, until product outlet; The finished product roll-over device is located on the cold bed.
Apparatus of the present invention are further improved, and the vertical rolls of a pair of active are set about vertical universal mill, a pair of driven horizontal machine roller of upper and lower settings; Vertical rolls are connected with main motor by power transmission shaft, the gear-box established thereon, and the vertical rolls rotation advances to roll over attenuate to web; Horizontal roll is connected with vertical rolls by rolled piece, drives workpiece motion s during the vertical rolls rotation, and the rolled piece of motion drives horizontal roll and rotates, and with the vertical rolls acting in conjunction spreading attenuate is carried out on the edge of a wing.
Vertical edging mill roll vertically is provided with, and is connected the control flange width with main motor by power transmission shaft, the gear-box established thereon.
When steel rolling is produced, the heating steel billet, through split rolling method, billet rolling becomes to have web, the H shape rolled piece on the edge of a wing, web is in level, the edge of a wing is in plumbness, through lifting finger turn over turn 90 degrees after, rolled piece is " worker " shape, the rolled piece web in vertical state, vertical universal mill is sent into level in the edge of a wing, main motor is through gear-box, power transmission shaft drives the vertical rolls rotation, horizontal roll is by motion rolled piece driven rotary, again under the effect of edging mill, on one side to the height of rolled piece, the width on the edge of a wing is rolled, on one side the wall thickness on the web and the edge of a wing is carried out the spreading attenuate.In entering, after the finish rolling, the web of rolled piece always is in plumbness, and the notch of the elongated slot that is made of the web and the edge of a wing opens wide both sides to the left and right, and the cooling water of roll only splashes down to both sides from the elongated slot top, so the rolled piece temperature drop is very little.Cut off behind the roll forming, turn over again to turn 90 degrees behind the last cold bed and cool off.
Compared with prior art, its advantage rolled piece temperature drop reduces significantly, rolled piece can remain under the higher temperature and be rolled, roll-force and moment are little, reduced the energy consumption that steel rolling is produced, what is more important rolled piece temperature drop reduces, and can make the spreading of rolled piece wall thickness get thinner, produce the product variety and the specification of the H shaped steel that is difficult to the light thin wall produced at present, enlarged the range of application of H shaped steel.
