Abstract
The utility model relates to a large heating furnace for round billets, which comprises a furnace body, a heat accumulating type burner, a slide way and a material stirring device, wherein the material stirring device comprises a motor, a speed reducer, a hollow transmission shaft and two material stirring arms which form a certain angle with each other. The two material stirring arms form an included angle of 50 to 90 degrees. The two material stirring arms are connected by a strengthening rib. The cooling water penetrates through the inside of the material stirring arms, the hollow transmission shaft and the strengthening rib for carrying out enforced water cooling. A material blocking arm and the strengthening rib can be made of heat resisting cast steel or normal steel. A slide way has a horizontally downward inclined angle from 3 degrees. to 5 degrees. in the advance direction. Because the material stirring device adopts the water cooling mode, the utility model can resist high temperature of the furnace, and the service life of the equipment is prolonged. The utility model not only solves the problem of steel piling up on the bottom of the furnace, but also makes the heating furnace larger. By using the heat accumulating type burner to control the weak reducing atmosphere in the furnace, the thermal efficiency can be raised, the metal loss can be reduced to less than 0.5%, and the billet heating temperature is even.
Description
Technical field
The utility model relates to a kind of heating furnace of metal fever processing usefulness, particularly relates to a kind of seamless steel pipe circle base heating furnace.
Technical background
In seamless steel tube production process, high temperature heating of pipe blank stove mainly contains following three kinds: what extensively adopt is annular furnace, secondly is walking beam furnace and wedged bottom stove.Above-mentioned three kinds of heating type of furnaces maximize and all have very big difficulty.And the energy consumption height, investment is big.Wherein the investment of wedged bottom stove is less, but the back heap steel problem that maximizes is difficult to solve.
Summary of the invention
The purpose of this utility model is exactly for overcoming the defective that above-mentioned prior art exists, and a kind of large-scale round base heating furnace is provided, and this heating furnace adopts accumulation of heat rolling step-by-step movement, has both solved wedged bottom stove heap steel problem, and heating furnace is maximized.
The technical scheme that adopts is:
A kind of large-scale round base heating furnace comprises body of heater, heat-accumulating burner, slideway, poking device composition.Wherein poking device is made up of motor, reductor, Hollow Transmission Shafts and two material toggling arms being mutually certain angle, and two material toggling arms become 50-90 ° of angle, connect as one with reinforcement between the two material toggling arms.
Above-mentioned material toggling arm, Hollow Transmission Shafts and reinforcement inside all feed cooling water, carry out Forced water cooling but.Backgauge arm, reinforcement both can be used heat resisting cast steel, also can use ordinary steel.Slideway has the downward inclination angle 3-5 of level ° in direction of advance.
The material toggling process of material toggling mechanism is: the material toggling arm rotates under the motor transmission, when the material toggling arm contacted with pipe, the material toggling arm promoted pipe and rolls forward, when the material toggling arm disengages with pipe, another material toggling arm rotates to the slideway top, blocks the back and rolls across next pipe.Power transmission shaft rotates a circle, the pipe station that advances.
The utlity model has following advantage:
1, because material toggling mechanism adopts water-cooled, be not afraid of furnace temperature and raise, improved service life of equipment.
2, round base is rolled on slideway and advance, both solved wedged bottom stove heap steel problem, heating furnace is maximized.
3, use heat-accumulating burner can control weak reducing atmosphere in the stove, both can improve the thermal efficiency, can reduce iron loss again, scaling loss can be controlled the level less than 0.5%, makes billet heating temperature even.

The specific embodiment
Embodiment:
A kind of large-scale round base heating furnace,, comprise by body of heater 5, heat-accumulating burner 1, slideway 4, poking device and form 6.Wherein poking device 6 is made up of motor 2, reductor 3, Hollow Transmission Shafts 10 and material toggling arm 8 and material toggling arm 11,11 one-tenth 52 ° of angles of material toggling arm 8 and material toggling arm, and material toggling arm 8 and material toggling arm 11 connect as one with reinforcement 9.Material toggling arm 11 length are shorter than material toggling arm 8 length, and wherein material toggling arm 8, material toggling arm 11, Hollow Transmission Shafts 10 and reinforcement 9 inside all feed cooling water, carry out Forced water cooling but.Downward-sloping 2 ° in slideway in pipe direction of advance level.
The material toggling process of poking device 6 is as shown in Figure 3: material toggling arm 8 rotates under motor 2 transmissions and reaches position A, this moment, the position of pipe 7 was a, this moment, material toggling arm 8 was with pipe 7 contacts, material toggling arm 8 promotes pipe 7 and is rolled to position b forward, and this moment, material toggling arm 8 positions were B, when material toggling arm 8 in-position C, pipe 7 positions are c, material toggling arm 8 disengages with pipe 7, and material toggling arm 11 rotates to the slideway top, blocks the back and rolls across next pipe.Power transmission shaft rotates a circle, the pipe station that advances.So circulation has realized that the rolling of pipe in stove advance.
