Abstract
The invention provides a fast alignment method for a blast furnace top ring. The specific technical scheme is that the method comprises the following steps: step one, adjusting nuts are welded; step two, the top ring is hoisted to a furnace shell seal cover, and a cross center mark of the top ring corresponds to vertical and horizontal center lines of the furnace shell seal cover; and step three, the levelness of the ring is adjusted, measuring sliding staff is placed on an upper plane of the ring, and the levelness of the top ring is adjusted through bolts according to the height difference of an eyeball of a level gauge. A fast alignment device for the blast furnace top ring comprises four sets of nuts and bolts, the four sets of nuts are fixedly arranged on the cross center lines on the inner side of the upper port of the blast furnace shell seal cover and are symmetrically arranged with the circle center of the upper port of the blast furnace shell seal cover as the center, and the four sets of bolts are in threaded connection with the nuts. The fast alignment method and device for the blast furnace top ring have the advantages that not only the alignment precision is high, but also the alignment time of the blast furnace top ring is shortened, and the cost is reduced.
Description
Technical field
The present invention relates to equipment field engineering field, particularly a kind of fast aligning method of blast furnace roof steel ring, is particularly useful for the fast aligning of blast furnace roof steel ring.
Background technology
In existing metallurgy construction, the aligning method that blast furnace roof steel ring is installed welds baffle plate on furnace shell and steel ring, and then regulate with screw block, time-consuming, be awkward, efficiency is low, affects the installation period of furnace top equipment.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fast aligning method and device of blast furnace roof steel ring, and not only centering precision is high, and shortens the alignment time of blast furnace roof steel ring, reduces cost.
For achieving the above object, the fast aligning method of a kind of blast furnace roof steel ring that the present invention proposes, its concrete technical scheme is:
The first step, welding setting nut, is welded on the cross centre line of last furnace shell seal closure inner side suitable for reading by the plain nut that four covers are installed respectively;
Second step, lifting lip ring, is lifted into lip ring on furnace shell seal closure, and the cross searching of lip ring is marked, and medullary ray is corresponding in length and breadth with furnace shell seal closure;
3rd step, regulates steel ring levelness, is placed in the upper plane of steel ring, according to the discrepancy in elevation of spirit-leveling instrument eyeball, is regulated the levelness of lip ring by bolt by measurement Sopwith staff.
A kind of fast calibrating device of blast furnace roof steel ring, it comprises four cover nuts and bolts, the cross centre line that described four cover nuts are fixedly installed on last furnace shell seal closure inner side suitable for reading is symmetrical arranged centered by the last furnace shell seal closure center of circle suitable for reading, and four described cover bolts and nuts are threaded connection.
The fast aligning method of a kind of blast furnace roof steel ring proposed by the invention and device, not only centering precision is high, and shortens the alignment time of blast furnace roof steel ring, reduces cost.
Accompanying drawing explanation
Fig. 1 is that the fast aligning method of a kind of blast furnace roof steel ring proposed by the invention arranges schematic diagram.
Fig. 2 is A-A sectional view in Fig. 1.
Embodiment
See accompanying drawing, a kind of fast aligning method of blast furnace roof steel ring, its concrete technical scheme is:
The first step, welding setting nut 1, is welded on the cross centre line of last furnace shell seal closure 5 inner side suitable for reading by the plain nut that four covers are installed respectively;
Second step, lifting lip ring 3, is lifted into lip ring on furnace shell seal closure, and the cross searching of lip ring is marked, and medullary ray is corresponding in length and breadth with furnace shell seal closure;
3rd step, regulates steel ring levelness, is placed in the upper plane of steel ring, according to the discrepancy in elevation of spirit-leveling instrument eyeball, is regulated the levelness of lip ring by bolt 2 by measurement Sopwith staff 4.
A kind of fast calibrating device of blast furnace roof steel ring, it comprises four cover nuts 1 and bolt 2, the cross centre line that described four cover nuts are fixedly installed on last furnace shell seal closure inner side suitable for reading is symmetrical arranged centered by the last furnace shell seal closure center of circle suitable for reading, and four described cover bolts and nuts are threaded connection.
The fast aligning method of a kind of blast furnace roof steel ring proposed by the invention and device, not only centering precision is high, and shortens the alignment time of blast furnace roof steel ring, reduces cost.
