Abstract

The utility model discloses a ladle sliding nozzle mechanism which comprises an upper nozzle, a lower nozzle, an upper sliding plate, a lower sliding plate, a hydraulic cylinder and an argon blowing pipe, wherein the upper sliding plate is fixed at the bottom end of the upper nozzle, the lower sliding plate is fixed at the upper end of the lower nozzle, and the upper sliding plate is contacted with the lower sliding plate. A vent plug is mounted on the lower sliding plate in an embedded mode, the argon blowing pipe is arranged on the vent plug in a penetrating mode, and one side of the lower sliding plate is connected with the hydraulic cylinder. The ladle sliding nozzle mechanism can simultaneously blow argon when tapping is processed, the argon enters into a ladle through the vent plug to stir molten steel, homogenization of composition and temperature of the molten steel is achieved, automatic open pouring of the ladle is ensured, tapping time is saved, and turnover rate of the ladle is improved.

Description

A kind of steel ladle sliding water gap mechanism

Technical field

The utility model belongs to the smelting iron and steel technical field, especially relates to a kind of steel ladle sliding water gap mechanism.

Technical background

In smelting iron and steel, particularly in the smelting of special steel, water for guaranteeing opening of ladle, adopt the blowing argon gas method more, make the molten steel in the filling pipe end seethe, not solidify, this method also is beneficial to the impurity come-up in the molten steel, improves the quality of steel.At present, slide gate mechanism of the prior art generally is made up of filling pipe end, upper slide, the following mouth of a river, lower skateboard and positioner thereof etc., and filling pipe end and upper slide are fixed on ladle bottom; The following mouth of a river and lower skateboard are installed in the slide plate box of slide mechanism; The mouth of a river is closed up and down when tapping, when cast is prepared, through the external force effect; Be gauge tap and the size of regulating steel stream; Poring rate is meeted the requirements, simultaneously, need on the ladle wall, punch in addition when in ladle, carrying out the Argon operation and dispose independent argon blowing system; And the following mouth of a river that refractory material supports just needs to change with lower skateboard in use for some time, and lower skateboard is to use bolt or monolateral taper to fix with the lower skateboard carriage usually, loads and unloads inconvenience, wastes time and energy during replacing.

Summary of the invention

In order to address the above problem, the purpose of the utility model provides a kind of steel ladle sliding water gap mechanism.

For realizing aforesaid goal of the invention, the utility model will adopt following technical scheme:

A kind of steel ladle sliding water gap mechanism; It comprises filling pipe end, the following mouth of a river, upper slide, lower skateboard, hydraulic cylinder and Argon pipe, and described upper slide is fixed on the bottom of filling pipe end, and lower skateboard is fixed on down the upper end at the mouth of a river; Upper slide and lower skateboard contact; Be embedded with porous plug on the described lower skateboard, be equipped with the Argon pipe on the porous plug, a side of lower skateboard is connected with hydraulic cylinder.

Owing to adopt technique scheme, the utlity model has following superiority:

This steel ladle sliding water gap mechanism can carry out Argon simultaneously when tapping, make argon gas pass through porous plug entering ladle and stir molten steel, makes molten steel composition, equalizing temperature; Guarantee the automatic casting of ladle, saved the tapping time, improved the turnover rate of ladle; Ladle can use continuously; Can make full use of the waste heat of last time, not only prevent to examine and grinned, improve the service life of ladle because of the refractory material that rapid heat cycle causes; The course of action of lower skateboard has improved accurate security, stability and production efficiency when pouring into a mould greatly through hydraulic cylinder control.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure: the 1-filling pipe end; The mouth of a river under the 2-; 3-Argon pipe; The 4-lower skateboard; The 5-upper slide; The 6-hydraulic cylinder.

The specific embodiment

In conjunction with Fig. 1, a kind of steel ladle sliding water gap mechanism, it comprises filling pipe end 1, the mouth of a river 2, upper slide 5, lower skateboard 4, hydraulic cylinder 6 and Argon pipe 3 down; Described upper slide 5 is fixed on the bottom of filling pipe end 1; Lower skateboard 4 is fixed on down the upper end at the mouth of a river 2, and upper slide 5 contacts with lower skateboard 4, is embedded with porous plug on the described lower skateboard 4; Be equipped with Argon pipe 3 on the porous plug, a side of lower skateboard is connected with hydraulic cylinder 6.

The utility model can carry out Argon simultaneously when tapping; Make argon gas pass through porous plug entering ladle and stir molten steel, make molten steel composition, equalizing temperature, guaranteed the automatic casting of ladle; Saved the tapping time; Improved the turnover rate of ladle, and the course of action of lower skateboard accurate security, stability and production efficiency when pouring into a mould have been improved greatly through hydraulic cylinder control.
