Problems solved by technology
Its disadvantages are: contact heating is required in the process of this hot pressing forming method, and at the same time, the flame contact on the surface of the pipe will cause oxidation, the temperature control is not precise enough, and the uniform temperature in the field cannot be formed at the same time, the overall structure is uneven, affecting The overall performance of the pipe fittings is not stable enough for local temperature control, and the final forming quality is not stable enough
The time is long, the production efficiency is low, and it is not energy-saving, so as to pollute the environment

Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with specific embodiments.
[0016] Such as figure 1 , figure 2 As shown, the hot-pressing three-way pipe billet heating and temperature control equipment in different regions includes L-shaped movable furnace base 1, L-shaped fixed furnace base 6 and induction eddy current heating device. There are three guide columns 5 under the L-shaped movable furnace base 1, Corresponding to the three guide post holes 10 of the L-shaped fixed furnace seat, the guide post 5 and the guide post holes 10 cooperate to play a guiding role when the furnace is combined. In the L-shaped movable furnace base 1, the upper and lower parts of the L-shaped fixed furnace base 6 are equipped with two pairs of infrared sensors 2 for sensing the internal temperature of the equipment. Both the L-shaped movable furnace base 1 and the L-shaped fixed furnace base 6 are equipped with a circulating water cooling device 3. According ...

The invention discloses hot pressing three-way pipe blank zone heating and temperature control equipment and a heating and temperature control method thereof. The hot pressing three-way pipe blank zone heating and temperature control equipment comprises an L-shaped movable furnace base (1), an L-shaped fixed furnace base (6) and an induced eddy current heating device. The induced eddy current heating device comprises an upper induction heating coil (7a), a lower induction heating coil (7b), a front induction heating coil (7c) and a back induction heating coil (7d) which are arranged on the upper portion, the lower portion, the front portion and the back portion of a pipe blank correspondingly. Circuits of the upper induction heating coil and the lower induction heating coil are independent of each other and can be controlled in a unified mode or controlled independently so that same or different magnetic fields used for heating the metal pipe blank can be produced. The front induction heating coil and the back induction heating coil are arranged in the axial direction of the pipe blank, and stable heating also can be achieved on the pipe blank end surface difficult to heat so that non-contact zone heating and an even temperature field can be achieved.
Description
technical field [0001] The invention belongs to the field of pipe forming equipment, and relates to a temperature control method for improving the grain structure of pipe fittings, in particular to a zone heating temperature control method, and a zone heating temperature control equipment designed based on the method. Background technique [0002] The forming process of the hot-pressed tee is to obtain the size of the tee through local plastic deformation of the tube blank. In order to achieve local plastic deformation, the usual heating method for the tube blank is to use a coke furnace or a reverberatory furnace to heat the tube blank as a whole and then locally heat the tube blank. , In the water cooling method, the heated tube blank is partially cooled to meet the requirements of the hot pressing forming process. Its disadvantages are: contact heating is required in the process of this hot pressing forming method, and at the same time, the flame contact on the surface o...
