Abstract
The purpose of the utility model is to provide a novel aluminum iron complex deoxidizer block so as to solve the problem of irregular speed and direction caused when the deoxidizer block immerses in molten steel. The technical proposal used for realizing the purpose of the utility model is that a novel aluminum iron complex deoxidizer block comprises an aluminum block body (1) and a counterbalance iron core (2) which is arranged in the aluminum block body (1). The novel aluminum iron complex deoxidizer block is characterized in that the deoxidizer block is in the shape of gyro or warhead, wherein, the iron core (2) is arranged on the head of the gyroscopic deoxidizer block or on the head of the deoxidizer block which has the shape of warhead. The novel aluminum iron complex deoxidizer block has the advantages that according to the fluid shape of the warhead and by applying aerodynamics knowledge and principle that resistance is the smallest in the air, the shape of warhead is invented. Through experiment and among various shapes, the deoxidizer block in the shape of warhead together with the counterbalance iron core sinks vertically and quickly in the molten steel and is difficult to float upward. Meanwhile, the warhead shape increases the contact area of the deoxidizer block and the molten steel, so that the heat transfer speed is fastened, the smelting time is shortened and the yielding rate of the aluminum is significantly increased, furthermore, the quality of steel-making products is improved and the cost is reduced, and the regular shape is also convenient for transportation, storing management and use.
Description
Technical field:
The utility model relates to the aluminum-iron composite deoxidizing agent piece that smelting iron and steel uses.
Background technology:
In steel smelting procedure,, often need to add deoxidizer block, reduce the unit cost of production simultaneously in order to improve recovery rate, and deoxidizer block out-of-shape commonly used, the face that contacts with molten steel when using is also smaller, and result of use is undesirable, has often influenced the recovery rate of aluminium.The disclosed a kind of novel aluminum Fe complex deoxidizer piece of Chinese patent CN2642790Y, it is a polyhedral frustum shape, or in middle perforate.It has improved the area that contacts with molten steel when using, and still, in the time of actual the use, the speed and the direction that sink to molten steel are all irregular, have influenced the effect of using.
The utility model content:
The purpose of this utility model provides a kind of novel aluminum Fe complex deoxidizer piece, solves the speed and all irregular problem of direction that sink to molten steel.
For realizing that the technical scheme that the utility model purpose adopts is: a kind of novel aluminum Fe complex deoxidizer piece, comprise aluminium matter piece body (1), with the counterweight iron core (2) that is arranged at piece body (1) inside, it is characterized in that: this deoxidizer block profile is gyro shape or warhead form.
Described iron core (2) places gyro shape deoxidizer block front end, or the front end of warhead form deoxidizer block.
Advantage of the present utility model is: according to the profile of sub warhead flow-like, applied aerodynamics knowledge, the principle of resistance minimum in air, invention bullet profile, by test, in different shape, this profile is under the situation that adds the counterweight iron core, deoxidizer block vertical subsidence and speed in molten steel is fast, is difficult for come-up.Simultaneously this shape increases the contact area of deoxidizer block and molten steel, accelerates heat transfer rate, shortens the heat, and significantly improves the recovery rate of aluminium, thereby has further improved the steel-making quality product, has reduced cost.The shape of rule also is convenient to transportation, storage management and use.

Embodiment:
A kind of novel aluminum Fe complex deoxidizer piece, this reductor is gyroscope-like, and a kind of novel aluminum Fe complex deoxidizer piece comprises aluminium matter piece body 1 and is arranged at the counterweight iron core 2 of piece body 1 inside, and this deoxidizer block profile is gyro shape or warhead form.Described iron core 2 places gyro shape deoxidizer block front end, or the front end of warhead form deoxidizer block.Circular cone is put into this deoxidizer block of molten steel and can be sunk fast down during use, has improved with molten steel to contact effect, thereby has further improved the steel-making quality product, has reduced cost.
Claims (2)
1. a novel aluminum Fe complex deoxidizer piece comprises aluminium matter piece body (1) and is arranged at the inner counterweight iron core (2) of piece body (1), and it is characterized in that: this deoxidizer block profile is gyro shape or warhead form.
2. a kind of novel aluminum Fe complex deoxidizer piece according to claim 1 is characterized in that: described iron core (2) places gyro shape deoxidizer block front end, or the front end of warhead form deoxidizer block.
