Description

The horizontal blowing furnace body expansion method of non-ferrous metal metallurgy
Technical field
The invention belongs to horizontal bottom blowing furnace technical fields, and in particular to a kind of horizontal blowing furnace body of non-ferrous metal metallurgy Expansion method.
Background technique
Furnace construction used in non-ferrous metal metallurgy is that have a set of furnace body device, two sets of support devices, a set of transmission device Three parts form, and two rolling rings, one gear ring is housed on furnace body, is mounted on the support roller of two sets of support devices, by transmission device The rotation that motor drives speed reducer to drive gear ring to realize furnace body by pinion gear again.Furnace body is to be welded into cylinder after being rolled by steel plate Shape, both ends welding end socket form.Fire door, oxygen rifle mouth etc. that needs are outputed on furnace body are required according to smelting process.Furnace interior Inside, which is built, has refractory material to meet the needs of pyrolytic semlting.Support device is made of pedestal, roller frame, support roller, bearing, Its total weight for carrying furnace body.Transmission device is made of motor, shaft coupling, speed reducer, brake, pinion device etc..
With the continuous renewal of non-ferrous metal metallurgy technique, large-scale horizontal rotary furnace is needed, furnace length requires long enough. When lengthening transformation to stove, the stove that different smelting enterprises uses is of different sizes, in order to enhance production capacities, improves product matter Amount, most important restraining factors are exactly furnace body length, and to achieve the purpose that enhance production capacities, there are two types of methods, first is that newly doing Big stove, second is that lengthening original stove.It makees new stove and is equal to a newly-built factory, investment large period is long;And old stove transformation is most Good scheme, but not only lengthening furnace body length is transformed to old stove, more require improved furnace body to fully meet production Otherwise demand will lead to the serious consequence that original furnace body is scrapped.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
Summary of the invention
The present invention provides a kind of non-ferrous metal metallurgy horizontal blowing furnace body expansion method, comprising the following steps:
It removes end socket and post-processing: old furnace body one end end socket being cut off using piecewise uniform cutting mode, and notch is beaten Mill, obtains pre-processing old furnace body;
Pre- centering: being arranged laser on the pre-processing old furnace body, by adjusting the pre-processing old furnace body and newly-increased section furnace Position between shell carries out pre- centering, and the newly-increased section furnace shell and the pre-processing old furnace body are then carried out pre-welding processing;
Mounting and adjusting supporter: according to the support body position being located on the pre-processing old furnace body, by finite element analysis computation, New supporter is installed on the newly-increased section furnace shell;
Smart centering and welding: smart centering is carried out to the new supporter using laser leveler;Then substep welding manner is used The pre-processing old furnace body and the newly-increased section furnace shell are welded together;
After welding treatment: making annealing treatment furnace body welding position, to complete to the horizontal converting furnace furnace of non-ferrous metal metallurgy Body dilatation.
Based on above-mentioned, the step of pre- centering, is specifically included: first respectively in newly-increased section furnace shell and the pre-processing old The intracavitary measurement bracket for setting up same size of furnace interior type, opens up a unthreaded hole in the measurement carriage center, one of them Laser is provided in the unthreaded hole, then the position by adjusting the newly-increased section furnace shell makes the laser be directed at another light The newly-increased section furnace shell and the pre-processing old furnace body are finally carried out pre-welding by hole.
Based on above-mentioned, the step of mounting and adjusting supporter, is specifically included: according to being located on the pre-processing old furnace body Support body position, the position that new supporter is mounted on the newly-increased section furnace shell is determined by finite element analysis computation, Then the rolling ring gear ring in supporter is sleeved in the newly-increased section furnace shell exterior side wall, by the corresponding peace of pedestal in supporter Mounted in the rolling ring gear ring two sides and on the base install support roller group, make the central axis of the rolling ring gear ring with it is described The central axis of support roller group coincides.
Based on above-mentioned, the specific steps of the essence centering and welding include: described to being located at using laser leveler first Support roller group of the sum on the newly-increased section furnace shell on pre-processing old furnace body carries out centering;Then use automatic welding connection from furnace Implement to weld outside body, after the completion of outside weldings, opens furnace interior with carbon arc air gouging plane and be broken position, and be cleaned to external weldering Meat is polished smooth with angle grinder, is finally welded using hand handle weldering to furnace interior, thus by the pre-processing old furnace body and The newly-increased section furnace shell welds together.
It with horizontal blowing furnace body expansion method further include being visited to weld seam based on above-mentioned, described non-ferrous metal metallurgy The step of hurting.
Wherein, it in the removal end socket and post-processing step, needs to add supporting beam in old furnace body inside in advance, to prevent It causes to deform during cutting seal head end, meanwhile, generation cylinder is further avoided using piecewise uniform cutting and is cut Cut the deformation at position.For the ease of lifting, it is also necessary to welded on the end socket of removal in advance 4 hoisting rings and 4 hoisting rings around End socket center is uniformly distributed.
And the internal diameter unfitness of butt joint in the pre- centering step, after the pre-processing old furnace body and the newly-increased pre- centering of section furnace shell Less than 2mm.
Compared with prior art, the horizontal blowing furnace body dilatation side of non-ferrous metal metallurgy provided by the present invention is utilized Method, processing step are simple, scientific and reasonable;The position He support side of reasonable Arrangement supporter in the case where lengthening furnace body length Formula, guarantee furnace body normal table operation, improve yield, can reduce purchase again two grades of supporting way bottom convertors at This, shortens the period of construction, effectively improves the economic benefit of enterprise.
