Description
Technical field
The utility model relates to the short net of a kind of high power electric furnace supporting construction, belongs to electric furnace erection unit technical field.
Background technology
In electric furnace steel making equipment, furnace transformer is from indoor output, through short net (copper bundle through walls), connects water-cooled cable outward and joins with electrode, and what support short net is inside and outside water beam, three-phase electrode in stove with the steel scrap short circuit, make scrap melting become molten steel.At present; The installation of the short mesh portions of large power, electrically furnace transformer is to adopt support arm water beam and copper pipe employing through walls tangent plane is plug-in to be connected, and there is defective in this structure, in process of production; Short net and Shui Liang junction short circuit might occur and blow out fault, cause equipment to damage.Concrete defective is following:
1, supports water beam and short net syndeton outward; Using 4 M20 bolts to add insulating sleeve (micanite pipe), to cross the water beam fastening; Bolt and insulating sleeve bear the tangential force effect; Receive gravity effect on the vertical direction equally, under the situation of not considering other factors, totally four points of the thick insulating barrier of 3mm supports and rises insulating effect.Mechanical strength is not enough under stressing conditions, is prone to cause damage in insulation, and short circuit is blown out.
2, to add water-cooled cable about more than 3 tons in every short mutually net deadweight; The main stress point is on these four M20 insulated bolts; If consider under the actual working state, electric pole short circuit steel-making, the influence of other factorses such as the vibration of water-cooled cable; Then the bolt at this structure place is multiplied with the stressed meeting of insulation, and the insulating sleeve wearing and tearing are accelerated.
The outside of 3, lacking the net system is in the high-temperature region; Variations in temperature can not ignore the stainless steel bolt of 1Gr9Ti18Ni composition M20 and the influence of insulating sleeve mechanical strength; Variations in temperature and bearing down effect behind the actual motion some cycles; Displacement appears in system's tenesmus, and the clamping force of bolt will reduce.The free state of insulating sleeve be will certainly influence, the wearing and tearing and the short circuit of possibly losing efficacy made it.
For this reason, being necessary externally to support the water beam improves with the syndeton of short net.
The utility model content
The utility model technical problem to be solved provide a kind of support force by force, the short net of the improved high power electric furnace supporting construction that can not damage, be connected firmly because of factor affecting such as gravity and high temperature.
The technical scheme that solves the problems of the technologies described above is:
The short net of a kind of improved high power electric furnace supporting construction; Supporting outside between water beam and the short net increases dielectric support block, and dielectric support block is the rectangle collets, and dielectric support block is vertically placed; On the dielectric support block plate face medial axis circular hole perpendicular to the plate face is arranged; The diameter of circular hole and the diameter of short_net copper pipe are complementary, and dielectric support block is divided into two parts up and down along circular hole central horizontal direction, and the lower end of dielectric support block contacts with the outer upper surface that supports the water beam; In the both sides of dielectric support block the through hole that vertically runs through top and the bottom is arranged, be installed with connecting bolt in the through hole.
The short net of above-mentioned improved high power electric furnace supporting construction; Fastening outer 4 fastening bolts that support the water beam lay respectively at the outer both sides up and down of supporting the water beam; The inboard of supporting the water beam outside adds the weldering fixed head; It is fastening that insulation board and the fixed head that fastening bolt passes the outer Shui Liang of support both sides will support the water beam outward, between fixed head and fastening bolt, felt pad arranged.
The usefulness of the utility model is:
The outer support between water beam and the short net adds dielectric support block and fixing, supports as main, the radial load of the vertical gravity that can bear short net system when swinging; Fastening outer 4 fastening bolts that support the water beam lay respectively at the outer both sides up and down of supporting the water beam, and the inboard of supporting the water beam outside adds the weldering fixed head, can play and strengthen fastening booster action.The utility model uses the back stable equipment operation, never is short-circuited at this position to blow out fault, prolongs this position time between overhauls(TBO) more than 10 times.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the side view of Fig. 1.
Mark is following among the figure: support water beam 1, short net 2 outward, connect water-cooled cable 3, dielectric support block 4, connecting bolt 5, fastening bolt 6, insulation board 7, fixed head 8, felt pad 9.
The specific embodiment
The utility model supports between water beam 1 and the short net 2 outside increases dielectric support block 4, supports as main, the radial load of the vertical gravity that can bear short net system during with swing.
Show among the figure; Dielectric support block 4 is the rectangle collets, and dielectric support block 4 is vertically placed, and on the dielectric support block 4 plate face medial axis circular hole perpendicular to the plate face is arranged; The diameter of circular hole and the diameter of short_net copper pipe are complementary; Dielectric support block 4 is divided into two parts up and down along circular hole central horizontal direction, in the both sides of dielectric support block 4 through hole that vertically runs through top and the bottom is arranged, and is installed with connecting bolt 5 in the through hole.So just can from upper and lower short_net copper pipe be enclosed within the circular hole respectively, with connecting bolt 5 dielectric support block 5 be integrated then by two parts up and down of dielectric support block 4.The lower end of dielectric support block 4 contacts with the outer upper surface that supports water beam 1, and intermediate supports plays short_net copper pipe, plays main supporting role.
