Description
Technical field
The utility model belongs to high-speed rod steel rolling auxiliary equipment technical field, relates to a kind of and the cooling device matching used novel control cold water storage cistern of high-speed rod steel rolling equipment.
Background technology
In the high-speed rod steel rolling equipment, its main equipment includes mechanical part, electrical appliance part, hydraulic part and slave part, wherein the water tank control is cold is must obligato plant equipment in the high-speed rod rolling process, and determine concrete position and quantity of installing according to the required production steel grade in market by enterprise, its principal character is: the box structure that adopts cuboid, the round tubular horn mouth guide-tube structure element that can cross rolled piece is installed in casing, select the conduit in different apertures to pass through rolled piece according to the demand of producing simultaneously, its effect is that the cold requirement of rolled piece temperature control by the water tank intercooler is guaranteed to be cooled to process requirements in the regular hour, and guarantee the internal performance quality of rolled piece to play the guiding role simultaneously.
At present, existing water cooler is the direct injection cooling jet, mode with straight spray cooling is cooled off rolled piece, the water inlet of employing circumferential weld, current are the direct projection shape and are sprayed onto the rolled piece surface, the heat of rolled piece is taken away, realize the purpose of cooling, its shortcoming is: the one, because the sediment of supply channel is more, after production a period of time, the quality of cooling water just descends significantly, cause impurity and suspension in the cooling water to exceed standard, the circumferential weld of various nozzles is often blocked, causes the skewness of cooling water, each position cooling effect difference of rolled piece, so the rolled piece poker characteristic is also uneven; In addition, the circumferential weld of this water-cooled nozzle is regulated very inconvenient, can't know before assembling and use how thick pad, particularly can't detect the size of circumferential weld after the cooling jet assembling, does not know also whether circumferential weld distributes even.The 2nd, if circumferential weld is blocked, former water cooler must roll off the production line and take the fastening bolt at two ends apart, extracts conduit out and could remove foul; But clamping screw is often dead by rust, has only it is cut off ability overhaul nozzle, causes maintenance very inconvenient.The 3rd, under the condition of hydraulic pressure deficiency, can not thoroughly break the steam blanket of wire surface, cooling capacity is poor.The 4th, the water yield can not be full of cooler, easily causes the rolled piece inhomogeneous cooling, and there is tangible underworld in the surface, the poker characteristic inequality.The 5th, cooling effect is relatively poor, maximum one will improved production quality below 7O ℃, and an emphasis that carries out technology optimization is implemented temperature-controlled rolling exactly, each section temperature and finishing temperature in the particularly controlled rolling process are the relations of technical optimization and control so improve operation of rolling water-cooled case cooling capacity and control the rising of finish rolling built-in temperature.The 6th, the V-arrangement base closely cooperates in existing water cooler and the water tank, and installation and removal all will lean on aid or tup to hit, and are very inconvenient.When in producing, needing to change rolling specs, kind, also to change whole water cooler thereupon.Because the holder of water cooler is near the location of the V-shape base step in the water tank, very easily causes the rolling absolute altitude and the misalignment of water cooler when changeing, must be again centering centering one by one; When the fastening casting die of appearance was out of shape in the process of changeing simultaneously, often being forced to use the gas cutting excision could change; So not only waste time and energy but also waste spare part.
