Abstract
Disclosed is a jackscrew alignment method of a grate of an air heating furnace. The method comprises the steps: leading out transversal and longitudinal center lines of the grate on a furnace bottom board according to the size of a designed drawing; setting four jackscrew devices on each transversal and longitudinal center line of a grate support base, wherein each jackscrew is composed of a base and an adjusting nut; symmetrically setting locating pins on one sides of two jackscrew bases on each longitudinal center line; firmly welding the jackscrew bases and the locating pins with the furnace bottom board; and after support pillars of the grate are hoisted to the places, aligning levelness through the adjusting nuts according to the actually-measured height difference on the levelness of an upper plane of each support pillar of the grate by a level instrument. The jackscrew alignment method is simple in operation, convenient and fast to achieve, high in alignment efficiency, and capable of greatly shortening the alignment time of the grate, creating conditions for building the air heating furnace, shortening the project period and reducing cost.
Description
Technical field
The present invention relates to equipment mounting technique field, is a kind of Grates for Blast Heating Furnace jackscrew aligning method specifically, is applicable to the installation centering of Grates for Blast Heating Furnace equipment.
Background technology
In existing metallurgical construction, the aligning method that Grates for Blast Heating Furnace is installed mainly utilizes the taper liner plate to regulate, and time-consuming, the scope of operation is little, is difficult for adjusting, and efficient is low, and cost is high, affects the installation period that hot-blast stove is built by laying bricks or stones.
Summary of the invention
Purpose of the present invention is exactly the above-mentioned shortcoming that exists for prior art, and a kind of Grates for Blast Heating Furnace jackscrew aligning method is provided, and shortens the centering time of fire grate equipment, improves work efficiency, reduces costs.
fire grate jackscrew aligning method of the present invention is achieved in that a kind of Grates for Blast Heating Furnace jackscrew aligning method, be characterized in: first emit fire grate center line in length and breadth according to the layout design size on drop-bottom, on center line, four jackscrew devices are set in length and breadth at each fire grate bearing, jackscrew is comprised of base and adjusting nut, then two jackscrew base one sides on longitudinal centre line are symmetrical arranged alignment pin, again with jackscrew base and alignment pin and drop-bottom firm welding, after the fire grate pillar type hoisted is in place, according to the discrepancy in elevation of spirit level to plane levelness actual measurement on the fire grate pillar, come the centering levelness by adjusting nut, its step is as follows:
1) measure unwrapping wire: according to the layout design size on drop-bottom the measuring fire grate in length and breadth to center line;
2) install jackscrew base and alignment pin: install four jackscrew bases on center line in length and breadth at each fire grate pillar, then two jackscrew base one sides on longitudinal centre line are symmetrical arranged alignment pin, then with jackscrew base and alignment pin and drop-bottom firm welding;
3) by adjusting nut centering levelness: the fire grate pillar type hoisted to the jackscrew adjusting nut, according to the discrepancy in elevation of spirit level to plane levelness actual measurement on the fire grate pillar, is then adjusted the levelness on plane on the fire grate pillar by regulating the jackscrew nut.
The present invention is simple to operate, and is convenient and swift, and centering efficient is high, greatly shortened the centering time of fire grate, and the condition created of building by laying bricks or stones for hot-blast stove has shortened the duration, has reduced cost.
The invention will be further described below in conjunction with accompanying drawing and example.
Description of drawings
Fig. 1 is top view of the present invention.
Fig. 2 is cutaway view of the present invention.
In figure: 1, drop-bottom 2, jackscrew base 3, adjusting nut 4, alignment pin 5, fire grate pillar.
The specific embodiment
As shown in the figure, the present invention be first according to the layout design size on drop-bottom 1 measuring fire grate pillar 5 in length and breadth to center line, install four jackscrew bases 2 on center line in length and breadth at each fire grate pillar 5, then two jackscrew bases 2 on longitudinal centre line are symmetrical arranged alignment pin 4, again with jackscrew base 2 and alignment pin 4 and drop-bottom 1 firm welding, after fire grate pillar 5 hoisted in position, according to the discrepancy in elevation of spirit level to plane levelness actual measurement on fire grate pillar 5, adjust the levelness on plane on fire grate pillar 5 by adjusting nut 3.
Grates for Blast Heating Furnace jackscrew aligning method carries out as follows:
The first step is measured unwrapping wire.According to the layout design size on drop-bottom the measuring fire grate in length and breadth to center line.
Second step is laid jackscrew base 2 and alignment pin 4.On center line, four jackscrew bases 2 are set in length and breadth at each fire grate pillar 5, then two jackscrew base 2 one sides on longitudinal centre line are symmetrical arranged alignment pin 4, then with jackscrew base 2 and alignment pin 4 and drop-bottom 1 firm welding.
The 3rd step, adjusting nut centering levelness.Fire grate pillar 5 is lifted to jackscrew adjusting nut 3, according to the discrepancy in elevation of spirit level to plane levelness actual measurement on fire grate pillar 3, adjust the levelness on plane on fire grate pillar 5 by regulating jackscrew nut 3.
Used Grates for Blast Heating Furnace jackscrew aligning method of the present invention to carry out centering to fire grate when carrying out 2*1580m3 blast furnace (9#, 10#) Grates for Blast Heating Furnace installation in certain steel plant in 2012.On the effect fire grate, the difference in height on plane reaches 2mm, the deviation (on the standard fire grate, the plane levelness permissible variation is 4mm) that the plant equipment project installation acceptance specification that is better than smelting iron allows.Every Grates for Blast Heating Furnace centering time only needs 5 calendar day, needs 7 calendar day if carry out centering with the taper liner plate, 12 days reductions of erection time, 50000 yuan of two Grates for Blast Heating Furnace co-falling low costs.
