Embodiment
The synchronous strong convection refrigerating unit of a kind of recycling-guard atmosphere material all in one piece as shown in Figure 1, 2, be linked in sequence successively by the strong convection refrigerating unit 1 more than two groups and form, there are bellows 2 dragging roller below in each strong convection refrigerating unit, there are bellows 3 the dragging roller top, between dragging roller below bellows and the dragging roller top bellows recirculating air deferent 4 is arranged, recirculation blower 5 is arranged at bellows top, dragging roller top; At the strong convection refrigerating unit two ends that are linked in sequence successively is respectively inlet 6 and outlet 7, and heat-resisting partition fire door 8 is housed respectively on entrance and exit, in each strong convection refrigerating unit hygrosensor 9 is housed respectively.
Hygrosensor in each strong convection refrigerating unit connects single card microcomputer or PLC by analog to digital converter as shown in Figure 3, and single card microcomputer or PLC connect this strong convection of control refrigerating unit cocycle fan frequency converter by digital to analog converter.
As Fig. 4 is single card microcomputer or the synchronous strong convection refrigerating unit of PLC Control Circulation protective atmosphere material all in one piece program.
The synchronous strong convection refrigerating unit of a kind of recycling-guard atmosphere material all in one piece, be made up of the strong convection refrigerating unit more than two groups, blank enters cooled region fast by the roller bottom type passage, going into, exporting heat-resisting partition fire door is set at device, after blank entered cooled region, the front and back fire door was closed; Each atmosphere of organizing between the strong convection device circulates, by measuring the parameters such as temperature in each section cooling room, can independently control the rotating speed that respectively sprays the cold-zone frequency conversion fan and cooling power/also can organize whole cooling power by each cooling of bivariate mathematical model synchronization control, blank is swung at cooled region in process of cooling.
Every group of strong convection device is by the roller bottom type passage; The water jacket that all is provided with in the left and right sides of material roller-way, at the nozzle chest of dress up and down of material channel; Upper and lower bellows and air channel, side; Airtight recirculation blower; Water between top voltage stabilizing bellows and airtight recirculation blower/equipment such as gas interchanger are formed.
This installs applicable two kinds of types of cooling: 1) continuous operation cooling blank mode: this mode is applicable to the steel pipe (wall thickness＜25mm) and the bar of minor diameter (the quick cooling of diameter＜15mm) of thin-walled, blank passes through cooled region continuously, the position that the front and back fire door all is in out, the strong convection device can start 1～3 group (deciding according to processing requirement); 2) swing operation scheme (whole blank is the type of cooling simultaneously): this mode is applicable to heavy-walled steel pipe (wall thickness 15～50mm, 45 ℃～100 ℃ of the speed of cooling/Min) or the quick cooling of large diameter slightly bar, the blank quick integral enters cooling room, cut off fire door before and after closing, while ON cycle cooling blower, blank swing simultaneously, so both can prevent the convective exchange of gas in cooling room gas and the burner hearth, fan delivery and flow velocity can strengthen, (a blank part is in stove when moving continuously to prevent the radially heat conduction of blank inside simultaneously, a part is in cooling, inner generation thermal conduction), accelerate the speed of cooling of blank, treat that blank is cooled to require temperature to go further into next material level.
For example at high pressure boiler tube P91, P92 and some steel alloy, wall thickness require steel pipe to begin fast cooling to 650 ℃ or following with 1020 ℃ or higher temperature in the normalizing process of 22～50mm tubing, and rate of cooling is greater than 80 ℃/minute (cores).Application of the present utility model can realize this metalloid material is done quick cooling, and speed of cooling is adjustable; Equipment uses after being installed in the protective atmosphere heat treatment furnace, can satisfy the requirement of thermal treatment rate of cooling, realizes process goals such as metallographic structure and mechanical property.
