The mode of soft heat has three kinds usually in the continuous electroplating sheet tin production line at present: resistance reflow, induction reflow, associating soft heat.The finishing operation of these three kinds of soft heat modes all is Water Quenching, and its purpose is in order to prevent the at high temperature rapidly oxidation of tin layer after the tin trip soft heat, the finish plate that produces when keeping soft heat, and the shrend of carrying out cooling.During shrend, about 310 ℃ top temperature immerses the hardening groove during from soft heat with steel, is reduced to below 100 ℃.
Yet band molten steel quenching is process but, is the process that thermal zone steel directly contacts cooling after the soft heat with water, owing to can not in time be driven away with the bubble that steel soft heat hardening produces, the bubble rear dirt that breaks is attached to belt steel surface, forms easily water stain, water spots, has a strong impact on strip surface quality; Secondly, in band steel and the water contact process, produce a large amount of steam, bring disadvantageous effect to peripheral equipment and with the subsequent disposal of steel; In addition, in continuous flow procedure, hardening groove water temperature raises, and stanniferous amount increases in the hardening groove, will cause that so sticking tin phenomenon occurs conductive rollers in the rear operation, finally affects surface quality of strips, increases the maintenance of equipment expense.
Summary of the invention
The purpose of this utility model is, for Water Quenching above shortcomings in the existing soft heat operation, provides a kind of eleetrotinplate soft heat section contactless refrigerating unit.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
The contactless refrigerating unit of eleetrotinplate soft heat section, it comprises the water cooler that is fixed on the sealing on the unit steel structure platform, water cooler is along the fixed installation of band steel traffic direction, its inner both sides are provided with insulation steel casing, the intermediate formation cavity, be full of heat-eliminating medium in the casing, band steel entrance and the band steel exports of water cooler led to respectively at the cavity two ends; The band steel exports of water cooler also is provided with many to the Gas injection pipe along band steel traffic direction, the Gas injection pipe is fixedly connected with by the band steel exports of support with quick temperature control water cooler.
In such scheme, the band steel exports of water cooler leads to the 3rd deflector roll, and the 3rd deflector roll adopt from cooling off the steel deflector roll, and the 3rd deflector roll inside is provided with for the heat-eliminating medium to its roll body cooling.
Principle of work of the present utility model: the soft heat section strip steel is successively by being fixed on the first conductive rollers on the unit steel structure platform, the first conductive rollers pressure roller, the first deflector roll, the second deflector roll lead to the induction heater of heating with steel for giving, thermal zone steel after the induction heater heating is by the cavity in the water cooler that enters rapidly sealing with the steel entrance of water cooler, state by heat-eliminating medium in compressor and a series of refrigeration plant control water cooler two side box bodies, regulate the temperature of cavity, realization is to the cooling down of thermal zone steel, temperature can be adjusted according to the different zinc-plated amount with steel in the water cooler, if zinc-plated amount increases, also corresponding raising of temperature in the water cooler.The Gas injection pipe is by the pressurized air of winding-up cooling, the remaining condensation moisture of belt steel surface carried out secondary dries up and the band steel is carried out the secondary cooling.Turn to through supercooler cooling and dry leading to from the 3rd deflector roll that cool off steel with steel of crossing of gas injection tube, by the second conductive rollers and the second conductive rollers pressure roller, finish softening-melting process again, enter next process.By introducing heat-eliminating medium to the inner purpose that realizes the roll body cooling of its roll body, be conducive to extension device work-ing life from the 3rd deflector roll of cooling steel.
The beneficial effects of the utility model are:
(1) can realize that by water cooler the band steel after the soft heat does not directly contact with heat-eliminating medium in process of cooling, avoid occurring in the production process strip surface quality problem, fast cooling, cooling efficiency is high, simultaneously, the chiller temperature regulation range is large, and is easy to control, is conducive to produce the band steel of different size thickness; Simple in structure, be easy to control and safeguard;
(2) set up the Gas injection pipe by the band steel exports at water cooler, the condensation moisture that belt steel surface forms in quick temperature control water cooler can be dried up, guarantee that the band steel enters next process with drying regime;
(3) adopt the 3rd deflector roll that certainly cool off steel that cooled band steel is turned to, introduce heat-eliminating medium to roll body inside roll body is lowered the temperature, compare with the rubber roll of present use, this equipment replacement cycle, long service life are conducive to be with the steel continuous and stable production.
