Abstract
The utility model discloses a molten iron pretreating slag removing device, which is characterized in that an amplitude changing arm (5) is connected with a rotary upright post (3); a lifting oil cylinder (4) is connected with the amplitude changing arm (5) and the rotary upright post (3); the amplitude changing arm (5) is connected with the amplitude changing arm (9); the amplitude changing oil cylinder (6) is connected with the amplitude changing arm (5) and the amplitude changing arm (9); a spray gun (10) is inserted into the end of the amplitude changing arm (9); the spray gun (10) is communicated with a through hole of the amplitude changing arm (9), and then is fixed. When the utility model operates, the spray gun (10) is arranged on the rear part of a molten iron can; high-pressure nitrogen gas is ejected out of a hole of the spray gun (10) and drives slag forwards; simultaneously, a slag digging machine starts digging slag, and molten iron loses water reduction. Because the slag digging machine and slag removing operate together, the utility model has the advantages of compact structure and convenient replacement.
Description
The utility model belongs to the metal casting machine field, particularly a kind of device that is used for the skimming of motlten metal.
In metallurgical industry, smelt the high-grade steel, require its sulfur-bearing, phosphorus very low.Usually adopt and molten iron is being entered desulfurization before the smelting, phosphorus in the converter.This method is to add desulfurization, phosphorus agent in hot-metal bottle, makes sulphur, phosphorus form the surface that the bubble slag floats over molten iron, with tipple hot-metal bottle is tilted again, will steep slag with Cinder Machine and remove.Because Cinder Machine is taken molten iron out of often skimming, and causes the loss of molten iron.
The purpose of this utility model provides a kind of molten iron preliminary treatment floss skimmer.It can reduce molten iron loss when skimming, and compact conformation, and it is convenient to change.
For reaching above-mentioned purpose, feature of the present utility model is that rotary column is fixed on the column, the luffing arm is connected with rotary column, the two ends of elevating ram are connected with rotary column with the luffing arm respectively, luffing arm and luffing arm ' be connected with twisted axis, the two ends of amplitude oil cylinder are connected with two luffing arms respectively, and the microcephaly of spray gun injects luffing arm ' termination and is communicated with fixing with wherein through hole.
The major part outer wall of spray gun is provided with several apertures.Spray gun and luffing arm ' fix with ring flange.
Luffing arm ' be provided with baffle plate.
The utility model places the rear portion of hot-metal bottle when working owing to spray gun, the ejection high pressure nitrogen is caught up with slag forward from the hole of spray gun outer wall, forms thick slag blanket, and Cinder Machine begins to skim simultaneously, therefore makes the loss of Cinder Machine minimizing molten iron when working.Adopt Cinder Machine with catching up with slag to work, can make this apparatus structure compactness, and change conveniently.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a kind of example structure sketch of the present utility model.
Rotary column 3 is fixed on the column 1, luffing arm 5 is connected with rotary column 3, the two ends of elevating ram 4 are connected with rotary column 3 with luffing arm 5 respectively, luffing arm 5 is connected with luffing arm ' 9 usefulness twisted axis, the two ends of amplitude oil cylinder 6 are connected with luffing arm 5,9 respectively, nitrogen tube 8 enters the connector of luffing arm ' 9 through luffing arm 5 outsides, be communicated with wherein through hole.The microcephaly of spray gun 10 injects the termination of luffing arm ' 9 and is communicated with wherein through hole, fixes with ring flange.After hot-metal bottle 11 desulfurization, tumble and put in place, spray gun 10 is placed on the rear portion of hot-metal bottle 11, logical people's high pressure nitrogen sprays from spray gun 10 major part several holes through nitrogen tube 8, angling cylinder 2 drives rotary column 3 and luffing arm 5,9 and spray gun 10 swings, slag is caught up with forward, and Cinder Machine begins to skim simultaneously, and operation is finished to skimming.
The rotational fuel tank control crank makes angling cylinder 2, elevating ram 4 and amplitude oil cylinder 6 flexible, can make rotary column 3 and luffing arm 5,9 as required, finishes separately luffing, hoists and turns round action.
Luffing arm ' 9 are provided with baffle plate 7, splash on the amplitude oil cylinder 6 to prevent molten iron.
