Description
Technical field
The present invention relates to cooling procedure spiral stream guidance drainage arrangement after a kind of super wide super thick hot rolled plate rolling, belong to the hot rolling technical field, particularly the removal technology of coiled sheet remained on surface cooling water after the hot rolled plate rolling.
Background technology
In the production process of hot-rolled sheet coil, obtain higher economic benefit in order to improve the quality of products, obtain excellent mechanical performances, after rolling, generally adopted cooling facility for laminar flow to cool off.But in the cooling procedure of super wide ultra-thick plate volume, because the plate face is super wide super thick, original side-blown method and apparatus can not purge the coiled sheet surface clean, usually can cause super wide ultra-thick plate volume remained on surface that cooling water is arranged.General cooling water segregation produces plate shape and the unequal problem of mechanical property in the middle of the plate face.Particularly hot rolling manufacturing enterprise transforms cooling facility for laminar flow, adopts ultrafast refrigeration technique.Because the application of ultrafast refrigeration technique, the cooling hourly water consumption strengthens.The problems such as it is clean to adopt at present the water discharge method such as side spray purging and device more water residual on the steel plate can not be purged, and the plate shape wooden dipper that brings is bent, the mechanical property uniformity of steel plate is relatively poor are more outstanding.Therefore, the drainage problem of super wide super thick hot-rolled sheet coil remained on surface water is badly in need of solving.
Summary of the invention
The objective of the invention is cooling procedure spiral stream guidance drainage arrangement after a kind of super wide super thick hot rolled plate rolling, solve water discharge methods such as adopting at present the side spray purging and device and water residual on the steel plate can not be purged the problems such as the plate shape wooden dipper that totally bring mechanical property uniformity bent, steel plate is relatively poor.
Technical scheme of the present invention: cooling procedure spiral stream guidance drainage arrangement comprises frame, power section and by the water discharging part of its driving after the super wide super thick hot rolled plate rolling of the present invention, water discharging part comprise across hot rolled plate, be positioned at the hot rolled plate upper surface with the upper propellers of spiral stream guidance groove and be positioned at the hot rolled plate lower surface lower plain-barreled roll corresponding with upper propellers; The left-and-right spiral guiding gutter that has on the upper propellers is symmetric along body of roll center, and when hot rolled strip was carried out drain measure, its helix direction of rotation of spiral stream guidance groove was outside, and the residual water on the hot rolled strip is discharged to the two ends of propellers; The two ends of upper propellers and lower plain-barreled roll are installed on the frame by first pair and second pair of axle bed respectively, and propellers and lower plain-barreled roll are driven by motor and reduction box thereof.
First pair of axle bed periphery of described upper propellers is square frames, and square frame is positioned at the chute of frame, and square frame top is connected with the output of hydraulic mechanism.
The angle β of the axis of described spiral stream guidance groove and upper propellers=30 °～60 °, preferred angle β=45 °.
Described spiral stream guidance groove be width 10～50mm, the degree of depth of spiral stream guidance groove is 10～50mm.
The pitch L of described spiral stream guidance groove is 30～100mm.
Described upper propellers and lower plain-barreled roll are driven by two of a driven by motor reduction box synchronous, synchronized output shafts.The rotating speed of described upper propellers and lower plain-barreled roll is consistent with strip speed.The roll surface speed of namely going up propellers and lower plain-barreled roll equals strip speed.
The selection normal steel casting of the body of roll material of described upper propellers and lower plain-barreled roll.
Advantage of the present invention: the present invention discharges residual water water conservancy diversion on the cooled plate face of hot-rolled sheet coil by suitable groove depth and groove width, can the upper residual a large amount of cooling water water water conservancy diversion of super wide ultra-thick plate volume in the cooling procedure are clean, not only improve the mechanical property of hot-rolled sheet coil, and solved the bent plate shape poor that produces of steel plate wooden dipper that residual water causes.
Upper propellers and lower plain-barreled roll body of roll material can adopt normal steel casting, and the hot rolling slab speed of service of upper propellers and lower plain-barreled roll speed and production is consistent the blemish such as scuffing that can avoid the body of roll and belt steel surface to produce because of relative sliding.
Upper propellers can pass through according to the thickness of the hot-rolled sheet coil of producing the holding-down device of hydraulic on it, the spacing between adjustment and the lower plain-barreled roll.When having detected hot-rolled sheet coil and pass through, holding-down device of hydraulic moves down propellers, makes itself and lower plain-barreled roll closely press hot rolled strip, guarantees that the residual water on the plate face can discharge by helicla flute.
