Description

Integral running castings mold device of large-sized steel ingot clamp

Technical field

The present invention relates to a kind of integral running castings mold device of large-sized steel ingot clamp, belong to steel-making steel ingot technical field of mold.

Background technology

At present, along with power station, steel rolling equipment to large scale development, the single-piece weight of forged shaft such as rotor, backing roll is also increasing, and required steel ingot single-piece weight is also increasing, and the forging of large-scale steel ingot becomes a difficult problem, the conventional method that forges large-scale steel ingot is, afterbody with steel ingot is swaged into the pincers handle that is easy to clamping earlier, and clamping has the steel ingot upset forging type of pincers handle, and its deficiency is that the steel ingot firing time is long, steel ingot weight is big, the cost height; The external way that solves the overweight difficult problem of forging forged shaft equipment of using is only found Japan one tame enterprise, but what they adopted is that pincers are pre-buried casting, promptly forge with steel ingot in advance and be processed into the pincers handle that a size conforms is forged requirement, before cast, it is imbedded in the chassis, the upper end exceeds plane on the chassis, steel ingot is when cast, molten steel will clamp the upper end will be wrapped, make it to strike up partnership with steel ingot, for forging, postorder creates favorable conditions, help pincers from the chassis, deviating from smoothly, clamp little scale error; Its deficiency is: move to the ingot body on the steel ingot sedimentary pile, have a strong impact on ingot quality; Pincers can not fuse into one with steel ingot can only being wrapped by steel ingot, in postorder forges, easily come off from ingot or loosening, can not continue to finish the back and forge; To forge and be processed into steel ingot in advance and meet the pincers handle that forges dimensional requirement, not only waste a large amount of production costs, and bring difficulty to organization of production; The large-scale steel ingot pincers find no the report that closes this respect so far to the integrated poured blank that also is at home.

Summary of the invention

In order to overcome above-mentioned technical deficiency, the invention provides a kind of integral running castings mold device of large-sized steel ingot clamp, this integral running castings mold device of large-sized steel ingot clamp can not only solve the cast of various tonnage steel ingot pincers handles, and steel ingot pincers handle is that the one forging effect is good with steel ingot.

The technical solution adopted for the present invention to solve the technical problems is: it is by hot top, ring extension, ingot mould, the top bottom-disc guard ring, the low bottom-disc seat, facade resin tamper, steel cylinder, circular metal mat, the refractory brick bed course, tamper, refractory brickwork, the ring steel plate pad, the chassis cover is formed, the low bottom-disc seat is tiled in ground level, the top bottom-disc guard ring aligns and is placed on the low bottom-disc seat, in the top bottom-disc guard ring, build several layers of refractory brick bed course by laying bricks or stones, tamper is covered on refractory brick bed course upper berth, on tamper, build the annular refractory brickwork by laying bricks or stones, facade resin tamper is covered in the ring shop in the annular refractory brickwork, facade resin tamper and steel ring bonding, circular metal mat is placed in the steel ring, paste mutually with plane resin tamper the bottom, place the chassis cover at annular refractory brickwork top, mounting circular ring metal mat in the cover of chassis, on the top bottom-disc guard ring, ingot mould is installed, ring extension is installed on the ingot mould, hot top is installed on the ring extension; Upper and lower two parts are made on the chassis, i.e. top bottom-disc guard ring, low bottom-disc seat, the more common chassis of top bottom-disc guard ring manufacturing doubles and middle the perforation; The low bottom-disc seat is then thinner, works the effect that attaches of holding in the top bottom-disc guard ring; In concrete operations, with top bottom-disc guard ring, low bottom-disc seat fitly together to central seats that directly face the stage, the two-layer refractory brick bed course of flat block on the low bottom-disc seat, and sand or chromite sand are pacified in the farming of spreading the thick drying of 10mm-20mm, in case molten steel passes, be built into a circle refractory brickwork with refractory brick at farming peace sand or above the chromite sand; The appearance and size that roll of steel plate welds is overlapped the centre that is sitting in the space to the measure-alike mouth of a river with pincers, is filled to 2/3rds eminences with dry good farming peace sand or chromite sand on every side, fills and leads up with the resin chromite sand then; Prevent that farming peace sand or chromite sand from entering molten steel, spread circular metal mat, at refractory brickwork installed inside mouth of a river cover steel cylinder in the bottom of mouth of a river cover; Leave the space on the cover steel cylinder of the mouth of a river, make steel ingot form the mouth of a river when cast, like this, sedimentary pile further moves down when making ingot solidification, guarantees ingot quality, avoids pincers that root is cracked simultaneously; The chassis that assembles is sitting in the vacuum chamber, sits mould, ring extension and hot top more in the above.Like this, when ingot mould was poured into a mould, molten steel formed one and meets the pincers handle that forges dimensional requirement in the cover of the mouth of a river on chassis.

The invention has the beneficial effects as follows: overcome the shortcoming that has a strong impact on ingot quality that shipper pole comes on the steel ingot sedimentary pile; Because the pincers handle is integrated poured forming with steel ingot, avoided clamping in the postorder forging the phenomenon generation that from steel ingot, comes off or pine puts; It is simple to attach assembling, need not forge in advance the processing pincers, save substantial contribution and man-hour, only 296t steel ingot pincers are just economizing on the use of funds surplus in the of 100,000 yuan.
