Description
Technical field
The present invention relates to Nuclear power plants mechanical component processing technique field, relating in particular to a kind of ultrasonic frequency induction solid solution furnace, for carrying out solution treatment to the Stainless Steel Cladding of fuel for nuclear power plant element.
Background technology
Solution treatment, refers to that alloy being heated to high temperature single phase region constant temperature keeps, and makes surplus fully be dissolved into cooling fast after in sosoloid mutually, to obtain the thermal treatment process of supersaturated solid solution.The associated component 0Cr18Ni10Ti Stainless Steel Cladding of fuel for nuclear power plant element, carries out a solution treatment with regard to needs before the cold drawn processing of finished product.Prior art generally adopts oil oven or intermediate frequency furnace.Wherein oil oven adopts open firing, its flame direct heating body of heater, and there is the problem that thermo-efficiency is low, tubing is heated uneven, cannot ensure that the grain fineness number of product controls the process requirements in 7-8 level, the oxidation thickness that tube surfaces is formed; Intermediate frequency furnace is that melting is directly carried out to the raw material in body of heater in the magnetic field utilizing Medium frequency induction coil to produce, and adopts center heating-type, and be difficult to control tubing and be heated evenly, and magnetic loss is large, heating efficiency is low.How to improve the internal structure of existing machinery, tubing is heated evenly, the grain fineness number homogeneity of improving product, ensure that mechanical property consistence is the problem that those skilled in the art need to think deeply.
Summary of the invention
For solving the problem, the invention provides a kind of ultrasonic frequency induction solid solution furnace.
Concrete technical scheme of the present invention is as follows:
A kind of ultrasonic frequency induction solid solution furnace, comprises body of heater, transport roller, ultrasonic frequency ruhmkorff coil, condensing works and induction heating power and control device.Described body of heater be both ends open hollow heated chamber, comprise body of heater entrance and body of heater outlet; Described transport roller carries tubing to be processed, enters furnace body inside and pass from body of heater outlet by body of heater entrance; Described ultrasonic frequency ruhmkorff coil is fixed on inboard wall of furnace body; Described induction heating power and control device connect ultrasonic frequency ruhmkorff coil, for detecting the internal temperature of body of heater and regulating the voltage and current exported ultrasonic frequency ruhmkorff coil according to detected result; The water cooling box that described condensing works comprises water storage be connected the condensation water jet of this water cooling box, described condensation water jet is positioned at body of heater exit, for the tubing injection condensing water passed on the transport roller of body of heater.
By adopting in this way: the instantaneous high-temperature utilizing ultrasonic frequency ruhmkorff coil, the loose little characteristic of heat is heated to tubing.Because ultrasonic frequency ruhmkorff coil is evenly distributed on inboard wall of furnace body, the radiant heat energy that the tubing passed through by body of heater centre is received is even, and is subject to the thermal radiation of great number in the product unit time, makes product rise to recrystallization temperature fast.Utilize condensation water jet to spray water of condensation to tubing when tubing derives body of heater with transport roller, tubing is cooled rapidly, extremely short from the process time being warming up to cooling.Therefore relative to oil oven or intermediate frequency furnace, the oxide film that tube surfaces is formed is very thin.Simultaneously because tubing is evenly by load coil, total length heating status is consistent, and tubing grain fineness number after Quick uniform cooling can control in 7-8 level.
Preferably, in above-mentioned ultrasonic frequency induction solid solution furnace: described condensation water jet is symmetrically distributed in the both sides of body of heater outlet.
By adopting in this way: ensured that the cooling performance of deriving is more even, avoided causing tubing overbending because tubing inhomogeneous cooling is even and causing tube surfaces to abrade.
It is further preferred that in above-mentioned ultrasonic frequency induction solid solution furnace: described induction heating power and control device adopt the two close cycles pi regulator controlled by single chip machine controlling circuit.Described ultrasonic frequency ruhmkorff coil is also provided with quartz insulator protective tube.
Electric current and voltage is by two close cycles proportion integral control mode, and the voltage and current adopting which can automatically regulate ultrasonic frequency ruhmkorff coil to export, realizes power limitation control to greatest extent, ensures the consistence of workpiece heat.Quartz insulator protective casing can avoid metal pipe material Contact Heating coil to cause the potential safety hazard of electric shock, simultaneously due to silica tube inwall unusual light, can avoid contacting the outside surface scratch caused in tubing moving process.
Compared with prior art, it is more even that the ultrasonic frequency induction solid solution furnace that the utility model provides makes tubing be heated in solution heat process, and after solution treatment, tubing grain fineness number can control in 7-8 level, and product surface zone of oxidation is thin, mechanical property uniformity.

Embodiment
In order to be illustrated more clearly in technical scheme, be further described below in conjunction with each accompanying drawing.
The utility model embodiment 1 as shown in Figure 1:
A kind of ultrasonic frequency induction solid solution furnace, comprises body of heater 1, transport roller 2, ultrasonic frequency ruhmkorff coil 3, condensing works 4 and induction heating power and control device 5.Described body of heater 1 be both ends open hollow heated chamber, comprise body of heater entrance 11 and body of heater outlet 12; Described transport roller 2 carries tubing to be processed, to be entered inside body of heater 1 and export 12 from body of heater to pass by body of heater entrance 11; Described ultrasonic frequency ruhmkorff coil 3 is fixed on body of heater 1 inwall; By the coiling of 8mm copper tube, be designed to round screw thread inductor block, totally 24 circles, logical pure water cooling in copper tube when inner cavity size 30mm, work.This ultrasonic frequency ruhmkorff coil 3 is also provided with quartz insulator protective tube 31 with the potential safety hazard avoiding metal pipe material Contact Heating coil to cause electric shock.Described induction heating power and control device 5 connect ultrasonic frequency ruhmkorff coil 3, detect body of heater 1 internal temperature and regulate the voltage and current exported ultrasonic frequency ruhmkorff coil 3 according to detected result; The water cooling box 41 that described condensing works 4 comprises water storage be connected the condensation water jet 42 of this water cooling box 41, described condensation water jet 42 is positioned at body of heater and exports 12 places, to the tubing injection condensing water passed on the transport roller of body of heater 1.
In practice: tubing moves with transport roller 2, entered by body of heater entrance 11 in the cavity of body of heater 1 inside.The temperature in cavity responded to by induction heating power and control device 6, and regulated the electric current and voltage being delivered to ultrasonic frequency ruhmkorff coil 3 by two close cycles pi regulator with built-in single chip machine controlling circuit according to this temperature conditions detected, make the tubing on ultrasonic frequency ruhmkorff coil 3 pairs of transport rollers carry out concentrating heating.Tubing after heating solid solution exports 12 by body of heater and derives body of heater, sprays water of condensation by both sides condensation water jet 12, detects through practice, is no more than 30 seconds from being warming up to the whole process time of cooling.Relative to oil oven or intermediate frequency furnace, the time being in high temperature due to tubing is short, and the oxide film that tube surfaces is formed is very thin.Simultaneously because tubing is evenly by load coil, total length heating status is consistent, and tubing grain fineness number after Quick uniform cooling can control in 7-8 level.
