Description
(1) technical field
The present invention relates to single, double curvature slab perforate technology, particularly relate to single, double curved plate boring device of melting gasification furnace furnace shell and method.
(2) background technology
Melting gasification furnace is state-of-the-art in the world at present ironmaking equipment, and its perforate is had relatively high expectations to makers', and body of heater sheet material is thicker, be low-alloy steel, single, double curvature line style, perforate quantity is many, each absolute altitude is had an appointment 40 groups, and 4 every group, every group of mutual level in endoporus center; Opening diameter is little, about Φ 100mm, and diameter tolerance is 0～1mm, mutual alignment tolerance+2mm, and domesticly do not have the special special-purpose boring device that is used for melting gasification furnace furnace shell cooling cinclides and thermocouple hole at present.
(3) summary of the invention
The purpose of this invention provides the special-purpose boring device and the method for a kind of melting gasification furnace furnace shell cooling cinclides and thermocouple hole, solve a crucial difficult problem of cooling off cinclides and thermocouple hole perforate in the fusion and gasification furnace shell manufacture process, finish the perforate task of specification requirement height, single double-curvature panel on the slab.
The technical scheme that adopts is:
A kind of list or double-curvature panel boring method, employed equipment comprises in this method: perforate frock, connector and tapping machine.
1, perforate frock is the important foundation of tapping machine, is fixed together by connector and housing, its effect is a cutting angle of adjusting tapping machine, satisfies final perforate specification requirement, guarantees that the perforate frock has good intensity and rigidity, simultaneously simple in structure again, be convenient to construction.The perforate frock comprises slideway, slide plate and leading screw.Slide plate adopts slab to be processed into, and has dovetail groove on the slideway.Cross to focus on for fear of frock and leave the loss of weight groove on the slideway.Convex with dovetail on the slide plate.Slide plate is connected by dovetail groove with slideway.The screw groove is arranged on slide plate, be equiped with screw in the screw groove, screw is fixedlyed connected with slide plate, leading screw and screw engagement.The leading screw two ends are by being fixed on two leading screw axle bed supportings on the slideway.One end of leading screw is equipped with handwheel.Slideway is provided with a plurality of bolts hole, is installed with the adjusting bolt in each bolt hole.Adjust slideway and list or double-curvature panel by adjusting the adjusting bolt, as the angle between the furnace shell, to guarantee the angle direction of last perforate.
2, connector comprises magnet and connector support, and magnet is fixed on the connector support lower surface, and connector support top is the connector pressing plate, by the bolt that is installed on the connector pressing plate connector is fixedlyed connected with the perforate frock.
3, tapping machine.The preferred CIR-CUT automatic flame cutting machine of tapping machine.
List or double-side curvature plate as perforate on the fusion gas furnace shell, comprise following processing step:
1, the horizontal level of the upper edge mating holes of perforate frock is checked line, the center vertical curve of every group of hole of the centrally aligned of perforate frock (horizontal relationship mutually) is regulated levelness, the perpendicularity that bolt is adjusted slideway by adjusting.Centre position adjustment is entad adjusted definite according to the horizontal range of frock both sides and shell plates face;
2, levelness and the perpendicularity with level meter detection perforate frock panel reaches perforate setting requirement;
The levelness of 3, perforate frock panel and perpendicularity adjustment, detect qualified after, the magnet of connector is inhaled solid on the housing of desiring perforate, again the fixed head of connector is fixedlyed connected with the perforate frock.So just, the perforate frock is fixed on (being on the furnace shell) on the housing;
4, tapping machine is adsorbed on the slide plate of perforate frock with the tapping machine bottom electromagnet, starts tapping machine then, flame is left a wind line hole in the inside of hole line of cut elder generation, apart from about line of cut 24～26mm;
5, the center of tapping machine and the scale of perforate frock (are gone out length numerical value at the slideway surface marking, determine the tapping machine translation distance by numerical value before and after moving), aiming at the back inhales on frock, the center of the pivot mating holes of nozzle, carry out perforate by the revolution of setting and the pressure of cutting gas, the place, hole that point of origin is being held successfully in advance;
6, perforate finishes the back by rotational lead screw, makes screw drive slide plate and moves, and carries cutting machine and moves on to next perforate center and carry out perforate;
Use successfully the complete system of opening in about 5000 holes on the melting gasification furnace furnace shell of the present invention.
The important technological parameters of melting gasification furnace furnace shell perforate:
A, housing radius of curvature: radius R=7100mm suitable for reading, end opening radius R=5932mm;
B, perforate precision: institute is porose to be lateral aperture; Diameter tolerance is 0～1mm; Mutual alignment tolerance+2mm, each absolute altitude 40 groups of holes of having an appointment, 4 every group, every group switching centre entad, the mutual level in group endoporus center.
Adopt the present invention not only can perforate on various housing lists or double-curvature panel, and perforate quality height, satisfy the desired standard of perforate that the melting gasification furnace furnace shell cools off cinclides and thermocouple hole fully, the hole wall fairing after the perforate, diameter tolerance is 0～1mm, tolerance+2mm in mutual alignment between the hole.
