The specific embodiment
Attach troops to a unit in the cooling on the right side in the place ahead-or the switching mechanism 18 of quenching tank 1 have the axle 19 of a rotatable supporting, at this upper support arm for taking material 21 is arranged, this arm for taking material is positioned at and is used for accepting slab or sheet material 2 on the horizontal level, and can be together with being positioned at top slab or sheet material 2 is passed on by furnace bottom car 16.From horizontal level rotation or swing 90 ° to passing on the position, slab or sheet material 2 are upright state to arm for taking material 21 in this position by hydraulic jack 22.Slab or sheet material 2 are supported by ratchet 23 on the base in the setting process, and this ratchet can be loaded by hydraulic cylinder 24.Come the detection position by a unshowned position sensor, the setting of slab of wherein having imported or sheet material 2 is then carried out with automatic sequence in the artificial back that discharges.In order to accept slab or sheet material 2, slide 3 is lifted slightly, slab or sheet material 2 and ratchet 23 are thrown off, therefore ratchet is rotated away from.
Then slide 3 is fallen very soon, be used for cooling off slab or sheet material 2.After cooling fully, as be used in the past adjusting described like that, in conversely mode with automatic mode with slab or sheet material 2 taking-ups.2 of chilled slab or sheet materials or be placed on again on the furnace bottom car 16 perhaps can be transported with overhead crane, and mobile platform 17 sides are moved.
Fig. 3 represented one that erect in the above described manner and put into the slab 2 of 3 li of slides.In order to make slide 3 enter into 1 li of cooling bath together with slab 2 liftings, slide 3 is connected on the rope driving mechanism 4, and this mechanism leads by the rope cylinder 5 that is fixed on the slide 3, and the rope 7 that moves on directive wheel 6 before having.Three-phase alternating-current motor machinery coupling connection a kind of unshowned frequency adjustment, that have gearbox ground acts on rope cylinder 5 by coupling shaft.Slide 3 usefulness cylinders or wheel 8 guide to move on the moving track 9 that is arranged at 1 li of cooling bath.The position that is reduced to the slide 3 of 1 li of cooling bath and slab 2 fully together with slab 2 is seen shown in the dotted line among Fig. 3.
Described in the past slab of adjusting or sheet material 2 are furnished with the jet beam 11a that nozzle 10 is arranged in alignment with the broadside surfaces separately of slab or sheet material 2,11b (referring to Figure 4 and 5) for 1 li at cooling bath between moving track 9.These jet beams are connected in a chilled(cooling) water return (CWR) 12, as visible in detail by Fig. 2.
The cooling or the cooling means that change can be realized in chilled(cooling) water return (CWR) 12, and guarantees that the jet beam 11a to 1 li of quenching tank, 11b supply water with cooling slab or sheet material 2, not only in a kind of mode of pure nozzle operation but also according to a kind of mode of whirlpool operation.For example can divide into three kinds of situations:
The operation of-nozzle is used for the steel until the HV-of 15t;
-whirlpool operation is used for until the HV of 15t steel with until the high-quality steel of 10t;
-tank is used for until the HV of 10t steel and high-quality steel.
By jet beam 11a, 11b sprays slab or sheet material 2 with cooling water when nozzle moves.Here Zui Da low water level 13a is positioned at below the following seamed edge of slab or sheet material 2 during in cooling procedure at 1 li of quenching tank (same as in adjacent pump liquid pool 14).
Cooling water is by pump 25a, and 25b is from 14 li extractions of pump liquid pool, and process filter 26 is delivered to jet beam 11a, 11b.Be used for pump 25a, the rotational speed regulation of 25b just can limit ground supply cooling water according to the size and the thickness of plate.
The effect of filter 26 is the mill scale particles that block greater than nozzle bore, and therefore avoids stopping up.After each cooling procedure, it is washed with self medium.Flushing water caused a sintering groove 27 and the reduction on held water plane after the refrigerating work procedure.The Main Ingredients and Appearance of mill scale is deposited on the bottom of cooling bath 1, so groove bottom is cleaned constantly.
Be collected in 1 li of tank from the water of slab or sheet material 2 outflows, and pass through 14 li of spout hole 15a inflow pump liquid pools therefrom.
This in Fig. 5 in the cooling procedure very simple expression, that realize by quenching to slab or sheet material 2, when moving, passes through at nozzle from jet beam 11a, the injection water of the nozzle 10 of 11b carries out, and when cooling an annex and drainage joint 28 (referring to Fig. 2) closing always.Because moisture storage capacity is low when nozzle moves, therefore in a cooling procedure, just can reach the water temperature upper limit of permission.Thereby a part of warmed-up water just pumps to 27 li of sintering grooves with a pump 29 after described operation.Then fresh water is directly cooled off import 30 from one and import, until having reached the beginning temperature again.
Reduction amount and fresh water amount depend on the end temp of finishing operation and depend on the initial temperature of next refrigerating work procedure.Reduction amount/fresh water amount surpasses the water level in pump liquid pool 14.When the requirement of cooling is very high, can additionally leads to a bypass 31 and make the liquid level of tank 1 reduce (see figure 2).
Be again to have represented another kind of cooling procedure with Fig. 4 in very simple mode.As being used for nozzle when operation in the past, in same cooling device or same cooling bath 1, can realize quenching process by the whirlpool operation here, carry out (equally also as the wave in the usefulness cooling bath 1 among Fig. 3 is represented) with stable strong flowing in other words.
Slab or sheet material 2 is immersed in 1 li of the tank that high water level 13b is housed when whirlpool moves and is used for simultaneously from cooling off beam 11a, the water of 11b loads.Water is forced to be used for circulation-become a kind of forced convertion from a kind of free convection by nozzle 10, and this forced convertion can realize transmitting from slab or the better heat from sheet material to water than a kind of simple quenching bath.
According to quality of materials and desired performance (institutional framework), therefore the complete set of equipments that can add has been stored a cooling jig just in same cooling device 20 up conversion cooling procedures to this.Whole cooling procedure is undertaken by putting computer on one according to the cooling jig of a physical mathematics, and this computer allows to carry out water temperature, hydraulic pressure, flow and the adjusting from the nozzle of jet beam to the spacing of slab or plate surface.Except a kind of whirlpool operation or nozzle operation, under the situation that also can not have nozzle ejection on the same cooling device 20 selectively by immersing operation, cool off.
