Abstract

The utility model provides a molten iron blowing and slag removing device, which adds a section of lengthening arm between a lifting big arm and a blowing and slag removing pipe to form a three-section type blowing and slag removing device consisting of the lifting big arm, the lengthening arm and the blowing and slag removing pipe; the lower end of the lifting large arm and the upper end of the blowing slag-removing pipe are respectively welded with a fixing flange with a bolt hole, connecting flanges are welded at the two ends of the lengthened arm, and the lower end of the lifting large arm and the upper end of the blowing slag-removing pipe are fixed on the connecting flanges at the upper end and the lower end of the lengthened arm through bolts. The utility model discloses can effectively solve and blow and catch up with the problem that the slag pipe depth of insertion is not enough, improve and blow and catch up with the result of use after the resistant material of slag later stage shortens, effectively improve and blow and catch up with the life of slag pipe.

Description

Molten iron blowing and slag removing device

Technical Field

The utility model belongs to steelmaking mechanical equipment field especially relates to a molten iron blows and catches up with sediment device.

Background

The molten iron blowing and slag removing process is applied to a desulfurization and slag removing process, and can blow certain types of gas after desulfurization to ensure that the molten iron slag surface which has been tipped for a certain angle obtains power, and blow and remove slag in the direction of a slag removing machine, so that the slag removing efficiency can be improved, and the slag removing loss can be reduced. The molten iron blows and catches up with sediment device in the past all adopts the big arm of lift to connect one and catches up with the sediment pipe by blowing that resistant material was made, along with the increase of use frequency, blows and catches up with the consumption of the resistant material of sediment pipe, and it is not enough to form later stage depth of insertion, and it is not good to blow and catch up with the sediment effect.

Disclosure of Invention

The utility model provides a can solve and blow and catch up with the problem that the slag pipe depth of insertion is not enough, improve and blow and catch up with slag pipe life, improve and blow and catch up with the molten iron of sediment effect and blow and catch up with sediment device.

Therefore, the utility model discloses the technical solution who takes does:

a molten iron blowing and slag removing device comprises a lifting large arm and a blowing and slag removing pipe, wherein a section of lengthening arm is additionally arranged between the lifting large arm and the blowing and slag removing pipe to form a three-section type blowing and slag removing device consisting of the lifting large arm, the lengthening arm and the blowing and slag removing pipe; the lower end of the lifting large arm and the upper end of the blowing slag-removing pipe are respectively welded with a fixing flange with a bolt hole, the two ends of the lengthening arm are respectively welded with a connecting flange corresponding to the bolt hole of the fixing flange, the lower end fixing flange of the lifting large arm is fixed on the connecting flange at the upper end of the lengthening arm through a bolt, and the upper end fixing flange of the blowing slag-removing pipe is fixed on the connecting flange at the lower end of the lengthening arm through a bolt.

The utility model has the advantages that:

the utility model discloses the molten iron is blown and is caught up with sediment device extension arm can extend and change as required to can effectively solve and blow and catch up with the problem that the slag pipe depth of insertion is not enough, improve and blow and catch up with the result of use after the resistant material of sediment later stage shortens, effectively improve and blow and catch up with the life of sediment pipe, make and blow and catch up with the life of sediment pipe and improve to 40 times from 10 times.

Drawings

FIG. 1 is a schematic view showing the installation state of a molten iron blowing and slag removing device.

In the figure: the device comprises a lifting large arm 1, a bolt 2, an extension arm 3, a hot metal ladle 4, an air blowing and slag removing pipe 5, a connecting flange 6a, a connecting flange 6b, a fixing flange 7a and a fixing flange 7 b.

Detailed Description

It can be seen from figure 1 that the utility model discloses molten iron blows and catches up with sediment device, catch up with sediment pipe 5 including the big arm 1 that goes up and down, extension arm 3 and the gas of blowing, increased one section extension arm 3 between the big arm 1 that goes up and down and the gas catches up with sediment pipe 5 promptly, form by the big arm 1 that goes up and down, extension arm 3 and the gas of blowing catch up with the syllogic that sediment pipe 5 constitutes and blow and catch up with the sediment device. The lower end of the lifting large arm 1 is welded with a fixed flange 6a with a bolt hole, the upper end of the air blowing and slag removing pipe 5 is welded with a fixed flange 6b with a bolt hole, and the upper end and the lower end of the lengthened arm 3 are respectively welded with a connecting flange 7a and a connecting flange 7b which correspond to the bolt hole positions of the fixed flange 6a and the fixed flange 6 b. The lower end fixing flange 6a of the lifting large arm 1 is fixed on the connecting flange 7a at the upper end of the lengthened arm 3 through a bolt 2, and the fixing flange 6b at the upper end of the air blowing and slag removing pipe 5 is fixed on the connecting flange 7b at the lower end of the lengthened arm 3 through a bolt 2.
