Description
Technical field
The utility model relates to the metal molten steel apparatus for pouring technical field of smelting iron and steel, relates in particular to a kind of molten steel die casting argon protective device.
Background technology
The casting of metal molten steel is the indispensable flow process of metallurgy industry.In molten steel die casting process; the ladle bottom mouth of a river and feed trumpet be suitable for reading one section space exposed with air; affected the degree of purity of molten steel; if do not taked safeguard measure; be accompanied by air-breathing in a large number; can make steel ingot internal gas content increase; to cause secondary oxidation of steel, ingot steel casting in the past in addition, the operator feels by rule of thumb to bag the time; relatively long and very inaccurate to the bag time; open to water often to go out and cast-in-placely partially need open and water rear adjustment, be prone to and spatter steel pharynx flow phenomenon; splash on die wall and easily make the surface of steel ingot generation scab, affect Ingot Surface Quality.
And then the increase of steel ingot endogenous inclusion, affected steel ingot degree of purity and inherent quality.Therefore, how to adopt die casting protection cast, reduce N, O gas content and oxide inclusions in steel ingot, the major limitation link that oneself further improves through becoming the restriction ingot quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of molten steel die casting argon for protecting pouring device, prevents the air-breathing and secondary oxidation of steel stream in the molten steel casting process, thereby guarantees the molten steel clarity, improves ingot quality.
The purpose of this utility model is achieved in that molten steel die casting argon protective device of the present utility model, comprise and the feed trumpet argon gas annular steel pipe circle base be connected suitable for reading, be arranged on the steel of the octagon with the rotating shaft bracing frame on argon gas annular steel pipe circle base, the umbrella argon shield upper cover that octagon steel bracing frame connects therewith, the argon gas that is distributed on umbrella argon shield upper cover inboard give vent to anger distributor pipe and tension link control device, described argon gas distributor pipe one end and the argon gas annular steel pipe circle base of giving vent to anger joins, the other end is connected with octagon steel bracing frame, be equipped with the argon gas spray orifice on give vent to anger tube wall and the top of distributor pipe of argon gas, be provided with back-moving spring between described argon gas annular steel pipe circle base and octagon steel bracing frame, described argon gas annular steel pipe circle base and outside tunger tube are connected.
Described tension link control device is by the motor be arranged on argon gas annular steel pipe circle base, and the tension link that motor connects therewith forms, and described tension link bottom is connected with motor output shaft, and top is fixedly connected with octagon steel bracing frame.
The utility model has the advantages that:
1. because the utility model adopts the umbrella argon protective device, the bag timer is to closed condition, and summit also plays positioning action, made assuring really, can prevent that in waiting for casting process foreign matter from falling into the cast passage, avoided steel ingot to produce foreing impuritys.
Cast prerequisite forward direction cast passage passes into argon gas, and whole casting process makes air be completely cut off by argon gas, prevents that the molten steel secondary oxidation from producing interior giving birth to and being mingled with, and makes protection have integrality.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The A that Fig. 2 is Fig. 1 is to view.
Fig. 3 is the utility model working state schematic representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-3, molten steel die casting argon protective device of the present utility model, it is characterized in that comprising the argon gas annular steel pipe circle base 6 be connected with feed trumpet suitable for reading 12, be arranged on the steel of the octagon with rotating shaft 5 bracing frame 4 on argon gas annular steel pipe circle base 6, the umbrella argon shield upper cover 3 that octagon steel bracing frame 4 connects therewith, the argon gas that is distributed on umbrella argon shield upper cover 3 inboards give vent to anger distributor pipe 2 and tension link control device, described argon gas distributor pipe 2 one ends and the argon gas annular steel pipe circle base 6 of giving vent to anger joins, the other end is connected with octagon steel bracing frame 4, be equipped with argon gas spray orifice 1 on give vent to anger tube wall and the top of distributor pipe 2 of argon gas, be provided with back-moving spring 10 between described argon gas annular steel pipe circle base 6 and octagon steel bracing frame 4, described argon gas annular steel pipe circle base 6 is connected with outside tunger tube 14.
Described tension link control device is by the motor 9 be arranged on argon gas annular steel pipe circle base 6, and the tension link 7 that motor 9 connects therewith forms, and described tension link 7 bottoms are connected with motor output shaft, and top is fixedly connected with octagon steel bracing frame 4.
Of the present utility modelly on argon gas annular steel pipe circle base 6,4 blocks of magnet 8 are installed, whole device is fixed on feed trumpet suitable for reading.
In production process, when the high-temperature metal molten steel, from the mouth of a river 13 of ladle 11 bottoms pours into feed trumpet suitable for reading 12, argon protective device, in full closeding state, has completely cut off contacting of molten steel and air fully, can prevent that in waiting for casting process foreign matter from falling into the cast passage, avoid steel ingot to produce foreing impuritys; After ladle draining; centered by the summit of argon protective device, point is realized fast to bag; open argon protective device before cast, under the effect of tension link control device, whole umbrella argon shield upper cover 3 opens vertically upward; form ring protection; open the argon gas valve, argon gas upwards and to the inside sprays and forms argon gas curtain air-isolation, opens steel ladle slide board simultaneously; form annular shape argon shield around the steel stream that the mouth of a river 13 is watered out, thoroughly completely cut off contacting of molten steel and air.Prevent the secondary oxidation of molten steel and air-breathing in a large number, guaranteed Molten Steel Cleanliness, improved ingot quality.
