Abstract
The utility model relates to the technical field of argon blowing of steel-making continuous casting tundish in steel smelting industry, particularly an argon-blowing slag dam of a continuous casting tundish, which comprises steel through-holes distributed on a slag dam body, argon-blowing pipes are arranged vertically among the steel through-holes, the lower ends of the argon blowing pipes are connected with gas-permeable bricks, the two ends surfaces of each gas-permeable brick are exposed outside the slag dam body, and pipe connectors connected with an argon source are arranged at the upper ends of the argon blowing pipes. The number of the argon blowing pipes and the number of the gas-permeable bricks are both two. The argon-blowing slag dam reduces the contamination of non-metal inclusions to molten steel. The argon gas is blown in through the argon blowing pipes at the upper part of the slag dam and flows to the bottom of the tundish through the gas-permeable bricks at the inner layer and at the bottom of the slag dam. The argon gas goes upwardly from the bottom to the liquid surface to form the gas bubble shield which prevents the non-metal inclusions from moving from the steel receiving zone at the middle of the tundish to the steel casting zones on the two sides of the tundish and pushes the non-metal inclusions to move upwardly to the surface of molten steel in the steel receiving zone, thereby improving the purity of molten steel.
Description
Technical field
The utility model relates to smelting iron and steel steel-making continuous casting tundish Argon technical field, relates in particular to continuous casting tundish Argon slag blocking wall.
Background technology
Tundish is the continuous casting main equipment, handle the container of terminal stage as molten steel, inclusion size shows the rule result that influences of inclusion removal behavior in the tundish: slag blocking wall-dam combination control stream inclusion removal best results, in the tundish collision polymerization of strong turbulence regime field trash and upwards and the increase of surface velocity be main cause; Tundish beam district add to press down rapid device, though its fluid flow characteristics change, not remarkable to the influence of inclusion removal rate; Under the higher casting rate, can not improve the removal effect of field trash merely well by the optimization of flow control device.
Summary of the invention
The purpose of this utility model provide a kind of can stop that non-metallic inclusion enters both sides from the connected steel area at tundish middle part water the steel district, force inclusion floating to arrive molten steel surface, improve the continuous casting tundish Argon slag blocking wall of the cleanliness factor of molten steel.
The purpose of this utility model realizes by following technical proposals:
The utility model is achieved in that continuous casting tundish Argon slag blocking wall, comprise the steel mouth excessively that is distributed on the pushing off the slag body of wall, it is characterized in that being provided with vertical Argon pipe described the mistake between the steel mouth, the lower end of this Argon pipe is connected with air brick, two end faces of this air brick expose described pushing off the slag body of wall, and the upper end of this Argon pipe is provided with the pipe joint that is connected with argon gas source.
Described Argon pipe and air brick are two.
The utility model has the advantages that: that uses that the Argon slag blocking wall can stop that non-metallic inclusion enters both sides from the connected steel area at tundish middle part waters the steel district, forces inclusion floating to arrive molten steel surface, improves the cleanliness factor of molten steel.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
According to continuous casting tundish Argon slag blocking wall of the present utility model, comprise the steel mouth 2 excessively that is distributed on the pushing off the slag body of wall 1, it is characterized in that being provided with vertical Argon pipe 4 described the mistake between the steel mouth 2, the lower end of this Argon pipe 4 is connected with air brick 5, two end faces of this air brick 5 expose described pushing off the slag body of wall 1, and the upper end of this Argon pipe 4 is provided with the pipe joint 3 that is connected with argon gas source.
As shown in Figure 1, Argon pipe 4 described in the utility model and air brick 5 are two.
After adopting slag blocking wall Argon of the present utility model, reduced the pollution of non-metallic inclusion effectively to molten steel.Argon gas is blown into from the Argon pipe 4 on slag blocking wall top, is blown into the tundish bottom through slag blocking wall internal layer, bottom air brick 5.When argon gas floats to liquid level from the bottom, formed air barrier, what stopped that non-metallic inclusion enters both sides from the connected steel area at tundish middle part waters the steel district, forces the molten steel surface of inclusion floating to the connected steel area.
Claims (2)
1. continuous casting tundish Argon slag blocking wall, comprise the steel mouth excessively that is distributed on the pushing off the slag body of wall, it is characterized in that being provided with vertical Argon pipe described the mistake between the steel mouth, the lower end of this Argon pipe is connected with air brick, two end faces of this air brick expose described pushing off the slag body of wall, and the upper end of this Argon pipe is provided with the pipe joint that is connected with argon gas source.
