Description

A kind of stone tongs that waters injecting electrode with the cap mouth

Technical field

The utility model relates to metallurgy industry vaccum sensitive stove electrode and smelts casting equipment, particularly a kind of stone tongs that waters injecting electrode with the cap mouth.

Background technology

Vaccum sensitive stove is a kind of special converter.The pouring technology of vaccum sensitive stove is: pour the molten steel of high-temperature liquid state into ingot mould, water into the electrode bar ingot.

The most top teeming processes that adopt of the pouring technology of vaccum sensitive stove, generally be behind the mounting cap mouth of ingot mould top, to pour into a mould, carry out feeding by the cap mouth and control the size of shrinkage cavity and the degree of depth (shrinkage cavity that produces when as far as possible reducing electrode bar in condensation improves the electrode bar quality) on the technology.When the molten steel of vaccum sensitive stove was poured into a mould, the shape of general cap mouth was ring-like, and material is to make of the refractory material of fragility.Must be put into a same shape earlier during installation, but in the iron-clad of the big slightly 5～10mm of diameter, pour into a mould at the top that is installed to ingot mould simultaneously with iron-clad again.At present, the smelting tonnage of vaccum sensitive stove less (1-5 ton), the electrode bar ingot mould size, the ingot mould cap mouth size that are used for the vaccum sensitive stove cast are also less, cap mouth size is generally between Φ 290mm～Φ 430mm, weight has only 20～30 kilograms, basic adopt manpower transport, mounting means (because the cap gate material is the fragility refractory material, mechanical handing, installation, the cap mouth is fragile).

As 12 tons of vaccum sensitive stoves, its furnace charge charge weight maximum reaches 12t, smelt the increase of capacity along with the stove seat, the diameter dimension of the cast electrode bar of producing is also increasing, the diameter of cap mouth is also just corresponding to be increased, the rising of bulking value, make a dead lift, big ingot shape cap mouth (rising head diameter greater than Φ 430mm, 30～150 kilograms of the weight) difficulty that becomes is installed even can't realizes.With maximum gauge electrode bar Φ 710mm is example, and the salty amount of cap reaches more than 150 kilograms, and three people also can't carry out the carrying and installation work of cap mouth; Mechanical handing, the big ingot shape cap mouth of installation just become unavoidable technical matters.

Once adopted representative type clamp-type tradition suspender, clamp the external diameter of cap mouth, mechanical handing, the big ingot shape cap mouth of installation, can't carry out safety and steady to the cap mouth installs efficiently: squareness at first uncontrollable and that maintenance is certain is lifted by crane the cap mouth, enter iron-clad when vertical bank is spent greater than 5 when the cap mouth lifts by crane, the bottom can only enter 30～50mm and just sprain with iron-clad; Simultaneously because the gap has only 5mm between cap mouth and the peripheral iron-clad, even rising head is sling, because anchor clamps and cap mouth clamping mechanics have at least 100mm wide, equal to make the rising head diameter to increase 100mm at the retaining part diameter, make rising head can't put into iron-clad fully; Once more from the quality of cap mouth own, all use frangible thermal insulation and warm material (in order to reach the effect of insulation) to make, the intensity and the hardness of cap mouth are all very little, and the cap mouth must be handled with care, (the anchor clamps Clamping force is excessive, and the cap mouth very easily damages for clamp-type suspender Clamping force control difficulty; The anchor clamps Clamping force is too small, and the cap mouth easily breaks away from anchor clamps, falls damage), so the breakage of cap mouth, condemnation factor are higher, cause the raising of productive costs.

Find from practical condition, (existing 12 tons of vaccum sensitive stoves have Φ 520, Φ 580, Φ 710 to cap mouth diameter greater than Φ 430mm, 30～150 kilograms of weight) cap mouth the time install difficulty (because of needing in producing that the annular cap mouth that frangible refractory material is made steadily is assembled in the ring-type iron-clad of diametric clearance 5mm, become difficulty even can't realize of the operation that traditional manpower carries out carrying and installation; Equally, because the gap is very little between cap mouth and the iron-clad, if adopting the outer wall of traditional clamp-type clamp clamps cap mouth packs in the iron-clad, the Machinery Ministry branch of clamp clamps cap mouth position influences the cap mouth and fully steadily puts into iron-clad so, because the cap mouth can not steadily be put into, anchor clamps also just can not unclamp, and have brought a difficult problem to production.Therefore, to large-scale cap mouth clamp, the development of handling and mounting tools has been extremely urgent.
