Abstract
The present invention discloses a rolling method of z-shaped steel. Said rolling method is that after having been hot-rolled at 1220-1250 deg.C a cut-to-length steel billet is fed into a four-frame two-row type mill train by trackway, and then an vertical-rolled double angle reverse conjoined butterfly hole-form system is used to roll definite 14 rolling passes. Its equipment includes guide plate, guard plate, cover plate and blade, etc.. Said invention has the advantages of good stability of workpiece in pass, good two shoulder filling of finished product material and can effectively prevent the workpiece from overdrafting, underdrafting and sidedrafting, etc..
Description
The invention belongs to metal rolled method and technology field, particularly a kind of Z bar material rolling method and device.
In the prior art, rolling Z bar material method is, the scale steel billet is heated to certain temperature province after, send into mill train by roller-way; After adopting rolling several time of regulation pass series, just form the Z bar material.For example, the rolling mill practice that Chinese Panzhihua Iron adopted.But this technology significant disadvantages is: 1, since after adopting first cutting-in on 95.0 milling trains method of rolling on edge so that the poor stability of rolled piece in pass easily reverses and produces folding.2, owing to the defective of pass design, cause the shoulder drift angle of rolled piece not to be full of, and the drift angle occurs.3, owing to the defective of device, consequently rolled piece bores upper fin down easily and forms side sway in the operation of rolling.
One of purpose of the present invention is, at the problems referred to above, proposes a kind of rolled piece that can make and keep good stability in pass, can reduce it again and reverse Z bar material rolling method with folding.
Another object of the present invention is, provide a kind of rolled piece shoulder item angle is full of and prevents to bore under the rolled piece upwarp and the Z-shape steel material rolling device of side sway.
Below, in conjunction with purpose of the present invention, its technical scheme is explained as follows:
The Z bar material rolling method is, the scale steel billet is heated to 1220-1250 ℃ after, send into 95,0/8,00/,850 4 two row formula mill trains by roller-way, adopt rolling 14 passages of the reverse disjunctor butterfly hole type system of rolling on edge-double angle after, form the Z bar material.
The rolling further method of Z bar material is, earlier by rolling two passages of the trapezoidal edging pass for rolling of 950 milling trains, overturning enters the rolling four-pass in 950 milling trains (1) cutting-in hole after 90 °; Move rolled piece and enter in rolling seven moulding holes delivering to 800/850 mill train after once, (2) cutting-in hole and respectively roll once, form the Z bar material.
Z bar material rolling device comprises by guide plate and defends the guide and guards that plate is formed.Guide plate is a flat guide plate, is installed on the guide plate beam of milling train.Defending plate is that separate type is defended plate, and the defending on the plate-girder of upper and lower sides of each hole exits is installed respectively.800/850 milling train, 4 to 7 holes inlet hand hay cutter is equipped with cover plate and supporting plate.The shape of cover plate and supporting plate is identical with the shape of rolling piece that enters pass.From 7 pass drift angles in the 6th hole of 950 milling trains the 3rd hole to 800 milling train a false shoulder is arranged all.From the short-leg fore shaft in 6 holes, 800 milling trains the 4th hole to the is the semi-closed port pass.
Major advantage of the present invention is:
1, the good stability of rolled piece in pass is difficult for reversing and producing folding;
2, rolling back finished product material two shoulders are full of good;
3, avoided in the operation of rolling rolled piece to bore down effectively and upwarped and side sway, and the roll axial motion that causes because of the rolled piece section is asymmetric.

Below, in conjunction with the accompanying drawings the present invention is further described.
The Z bar material rolling method is, the scale steel billet is heated to 1220-1250 ℃ after, send into 95,0/8,00/,850 4 two row formula mill trains by roller-way, adopt rolling 14 passages of the reverse disjunctor butterfly hole type system of rolling on edge one double angle after, form the Z bar material.
Z bar material rolling device comprises by guide plate 3 and defends the guide and guards that plate 4 is formed.Guide plate 3 is a flat guide plate, is installed on the guide plate beam 1 of milling train, defends plate 4 and defends plate for separate type, is installed in defending on plate-girder 10 and the guide plate beam 1 of each hole exits upper and lower sides respectively.800 and 850 milling trains, 4 to 7 hole entrance sides are equipped with cover plate 5 and supporting plate 6.The shape of cover plate 5 and supporting plate 6 is identical with the shape of rolling piece that enters pass.From seven pass drift angles in the 6th hole that 950 milling trains the 3rd pass to 800 rolls a false shoulder 7 is arranged all.800 milling trains, 4 to 6 hole short-leg fore shafts are semi-closed port pass 8, and roll is 2.
The Z bar material rolling method is, linear products is heated to 1220-1250 ℃ after, send into 95,0/8,00/,850 4 two row formula mill trains by roller-way, adopt rolling 14 passages of the reverse disjunctor butterfly hole type system of rolling on edge one double angle.Earlier that steel billet is rolling twice in the trapezoidal edging pass for rolling of 950 milling trains, make rolled piece form the thin trapezoidal shape in thick one side on one side.Enter rolling four times of 950 milling trains (1) cutting-in hole after 90 ° of the rolled piece upsets, it is once rolling to move on to 950 milling trains (2) cutting-in hole again.Then, rolled piece is delivered to seven moulding holes of 800/850 mill train and respectively rolled once, form the Z bar material.
Z bar material rolling device comprises by guide plate 3 and defends the guide and guards that plate 4 is formed.Guide plate 3 is a flat guide plate, is installed on the guide plate beam 1 of milling train.Defend plate 4 and defend plate, be installed in defending on plate-girder 10 and the guide plate beam 1 of each hole exits upper and lower sides respectively for separate type.800 milling trains and 850 milling trains, 4 to 7 hole entrance sides are equipped with cover plate 5 and supporting plate 6.The shape of cover plate 5 and supporting plate 6 is identical with the shape of rolling piece that enters pass, has guaranteed that rolled piece advances not deflection of hole, helps stablizing two leg lengths.Seven pass drift angles from 950 milling trains the 3rd hole to 800 milling trains the 6th hole all have a false shoulder 7, and its effect one is the shoulder deformation temperature that keeps higher, and the 2nd, enough metal filled drift angles are arranged.800 milling trains 4 and 6 hole short-leg fore shafts are semi-closed port pass 8, and the roll axial motion that is used to avoid causing because of the rolled piece section is asymmetric washes out pass.Roll is 2.
Panzhihua Iron is produced according to the invention 310Z shape steel reach shown in the Chinese Industrial Standards (CIS) GB8604-88(table 1 through check).
