Abstract
The utility model relates to a semi-bright annealing device, comprising a stainless steel pipe, wherein two ends of the stainless steel pipe are respectively fixed on a left resistor chuck and a right resistor chuck which are respectively connected with a high-frequency rectifier; the left end of the stainless steel pipe is connected with one end of a metal pipe by a first ceramic connector, and the other end of the metal pipe is connected with a nitrogen tank; the right end of the stainless steel pipe is connected with an air extraction mechanism by a second ceramic connector; and the stainless steel pipe is further connected with an infrared temperature detector. The semi-bright annealing device has the benefits of not only well solving the problem of iron scale generated on the inner wall of the stainless steel pipe after annealing, but also being environment-friendly and safe in annealing process.
Description
Technical field
The utility model relates to a kind of annealing device of stainless steel tube, relates in particular to the structure of this annealing device.
Background technology
Stainless steel annealing is meant workpiece is heated to preset temperature that slow refrigerative metal heat treatmet technology after the insulation regular hour, the main purpose of this technology are to improve metallicity, reduce stress.
Electrically heated annealing device of the prior art is exposed to often and carries out in the air when stainless steel tube is annealed, and the surfaces externally and internally of the stainless steel tube after the annealing all has the thick iron scale of one deck like this.Not only generation damages but also drops easily in lubricating fluid iron scale to mould during stainless steel inside pipe wall reprocessing, has a strong impact on the quality of lubricating fluid.
Summary of the invention
The utility model technical issues that need to address have provided a kind of half-bright annealing device, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: stainless steel tube; The two ends of described stainless steel tube are fixed on left resistance chuck and right resistance chuck; Described left resistance chuck is connected hf rectifier respectively with right resistance chuck; Left end at stainless steel tube is connected with an end of metal tube by one first ceramic joint, and the other end of metal tube links to each other with nitrogen pot; The right-hand member of stainless steel tube links to each other with extraction sector by one second ceramic joint; On stainless steel tube, also connect an infrared thermometer.
Compared with prior art, the beneficial effects of the utility model are: not only well solved the iron scale problem that annealing back stainless steel inside pipe wall produces, and be environmental protection safety again in the annealing process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: stainless steel tube 1; The two ends of described stainless steel tube 1 are fixed on left resistance chuck 2 and right resistance chuck 3; Described left resistance chuck 2 is connected hf rectifier 4 respectively with right resistance chuck 3; Left end at stainless steel tube 1 is connected with an end of metal tube 6 by one first ceramic joint 5, and the other end of metal tube 6 links to each other with nitrogen pot 7; The right-hand member of stainless steel tube 1 links to each other with extraction sector by one second ceramic joint 8; On stainless steel tube 1, also connect an infrared thermometer 9;
The utility model is a kind of electrically heated annealing device that adopts shielding gas.Separate with a kind of stupalith between metal tube and the stainless steel tube.The resistance chuck has been installed the position that a slideway can arbitrarily change chuck according to the supplied materials length of metal tube by air pump control, placement, chuck place.Be full of shielding gas in the device before the electrically heated, Heating temperature is controlled by the infrared thermometry device.When being cooled off, adopt metal tube the end inflation the other end a kind of like this gas circulation mobile mode of bleeding to cool off.
The purpose of inflated with nitrogen mainly is in order to prevent the oxidation of inwall in the utility model, inflates an end by an end simultaneously and bleeds and play the effect of cooling.
