Description
Technical field
The utility model relates to the steel rolling process technical field, relates in particular to the multi-functional slab in a kind of hot-strip production scene.
Background technology
The high-pressure water descaling effect need be made regular check in the hot-strip production scene, and inspection method has two kinds.A kind of is to judge the size of hitting power by observing de-scaling water nozzle abrasion condition, this method is not directly perceived, can not see directly which type of defective faucet exists, another kind is to use model by hit other experiment with water under high pressure, such as aluminium sheet, judges the size of hitting power according to the depth of hitting vestige, this method belongs to the destructive test method, need often to change the experiment model, waste heavier, uneconomical.
Hot-rolled strip production line edger roll roll gap calibration adopts tape measure directly to measure distance between the roll gap usually, directly roll gap is demarcated, adopted this method, have the gap error of equipment, artificial measure error and error in reading, the measurement numerical precision is low, the width of band steel is controlled have a direct impact.
Summary of the invention
The purpose of this utility model provides the multi-functional slab in a kind of hot-strip production scene, can make things convenient for and carry out inspection of de-scaling water nozzle and edger roll roll gap calibration exactly.
For solving the problems of the technologies described above, the technical solution of the utility model is:
The multi-functional slab in a kind of hot-strip production scene is characterized in that the slab parallel sides is provided with demarcation face, and demarcation face is provided with to be prevented pressing groove, and the slab upper surface is provided with skin of paint.
Also be provided with anti-skidding seal on the described slab parallel sides.
Compared with prior art, the beneficial effects of the utility model are: draw materials conveniently, reuse, discovery de-scaling water nozzle fault that can be promptly and accurately is for better maintaining de-scaling water system has been created advantageous conditions; Use this slab to demarcate the edger roll roll gap, help the self study of Mathematical Modeling, improved the width accuracy of band steel, improve steel utilization ratio simultaneously, the de-scaling water nozzle hits the water experiment can carry out simultaneously with the edger roll roll gap calibration, has saved valuable time for overhaul of the equipments, and overall economic efficiency is considerable.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1-slab 2-demarcates the anti-anti-skidding seal of groove 4-that presses of face 3-
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, the multi-functional slab in a kind of hot-strip production scene, slab 1 parallel sides is provided with demarcation face 2, and demarcation face 2 is provided with to be prevented pressing groove 3, and slab 1 upper surface is provided with skin of paint.Also be provided with anti-skidding seal 4 on slab 1 parallel sides.
Before maintenance open rolling in latter stage, do the de-scaling water nozzle and hit the water experiment and demarcate the edger roll roll gap, use the utility model slab, convenient and swift, specific implementation method is as follows:
1, customization slab: utilize continuous casting billet, about 230 millimeters of thickness, wide about 1550～1650, utilize two sides of planer or milling machine processing slab length direction, make two side edge surface smooth, form demarcation face 2, width uniformity between slab demarcation face.According to the actual conditions of on-the-spot handling slab anchor clamps,, process anti-skidding seal 4 in the position of anchor clamps clamping slab.The effect of these decorative pattern seals is the frictions that increase slab and anchor clamps, prevents slab because influences such as paint cause coming off in the handling process, smashes miscellaneous equipment and injures personnel.Destroy the iron scale of slab upper and lower surface, the thin paint of upper and lower surface brush one deck.When the de-scaling high pressure water jets was mapped on the slab, the paint of corresponding site will be struck off, and stayed and hit vestige clearly, then according to the duty of hitting verification of traces de-scaling water hitting power and de-scaling water nozzle.From slab head to 1 meter position, process long 1 meter wide 100 millimeters high 150 millimeters the anti-groove 3 that presses in the bottom of each side of slab.The effect at this position is to cause producing when pressing accident when equipment or operate miss, when edger roll can't be opened, utilizes the oxygen rifle that the retaining part slab is severed, and protection equipment is saved the production time.
2, edger roll roll gap calibration: when demarcating roll gap,,, carry out the edger roll roll gap calibration because therefore width unanimity between slab demarcation face need not measure the developed width that directly just can import slab as long as edger roll is clamped slab.
1) 1 meter position of slab head is transported in the edger roll roll gap by roller-way, closes the edger roll roll gap, when clamping slab and roll-force and be shown as 50 tons of left and right sides, stop to depress.
2) calculate the roll gap data that timing signal is imported: S=1550mm-(F-50)/58.8, wherein 1550 is width of plate slab; F is actual roll-force; 50 is the benchmark roll-force of timing signal; 58.8 be the mill stiffness of vertical miller; S is a nominal data.Simplify the edger roll roll gap calibration by this device, reduce labour intensity, make edger roll roll gap calibration result accurately and reliably, and handling safety, simple.
3, the de-scaling water nozzle hits the water experiment:
Slab is transported in the De-scaling box by roller-way, carried out de-scaling water and hit experiment.Hit back peeling paint situation by observing, judge the water nozzle state.Can judge the size of hitting power, current scattering situation, amount of lap, water nozzle abrasion condition etc. by hitting pattern, as the water nozzle angular deflection appears, not not point-blank, just need to change or maintenance, can also hit the pressure state that the vestige degree of depth and readability are judged whole descaling system according to de-scaling water in addition.
Utilize the utility model judgement de-scaling water nozzle defective and de-scaling water system fault convenient and swift, and check result accurately and reliably; Demarcating the used slab of roll gap and de-scaling water strike experiment simultaneously is same block of slab, and one-object-many-purposes is saved resource, reduces material and has bad luck, and simplifies work flow, the minimizing activity duration, helps improving operating rate of rolling mill.This patent is promoted convenient, can be applied directly to domestic other hot-rolled strip production line.
