Description

A kind of novel air brick of steel ladle

Technical field

The utility model belongs to smelting iron and steel technical field of refractory materials, is specifically related to a kind of novel air brick of steel ladle.

Background technology

Known from institute, at ladle, carry out in metallurgy, forging process, to be blown into the inert gases such as argon gas to ladle inside, make molten steel in ladle, produce circulation, molten steel is fully stirred, make to be added on rapid melting, the dispersions such as alloy in molten steel, deoxidier, desulfurizing agent, impel molten steel component and temperature even, shorten the heat, reach enterprise and increase work efficiency, the object reducing production costs; Be blown into the field trash in the inert gas bubble absorption molten steel such as argon gas simultaneously, remove the non-metallic inclusion in steel, thereby reach the object that cleaning molten steel improves steel quality, ladle argon-blown is the current a kind of iron and steel smelting process generally adopting in a word, what wherein the Argon of ladle bottom adopted conventionally is to carry out in the mode of air brick, so air brick belongs to the important part of smelting iron and steel.

Air brick is arranged on the bottom of ladle, argon gas is introduced ladle by air brick, it requires air brick to have good gas permeability, corrosion resistance and security, prevent the generation of gas leakage, bleed-out accident, when residual brick height≤10cm, continue to use molten steel likely can spill from air brick, cause the personal safety of altering steel accident and then affecting operating personnel, increased entreprise cost input, therefore whether operating personnel can correctly judge the residual brick height of air brick, are the crucial parts that affects air brick safety in utilization.

Therefore,, based on the problems referred to above, the utility model provides a kind of novel air brick of steel ladle.

Utility model content

Utility model object: the purpose of this utility model is for the deficiencies in the prior art, a kind of novel air brick of steel ladle is provided, improve the security of using, can to air brick service condition, carry out early warning judgement in time, and then guarantee that operating personnel's personal safety, reduction enterprise production cost drop into.

Technical scheme: a kind of novel air brick of steel ladle, comprises air brick, shell, high temperature carbon pole and breather pipe; Described air brick is arranged on enclosure; Described high temperature carbon pole is arranged on air brick one end; Described breather pipe is arranged on shell one end.

Preferred described shell adopts galvanized iron sheet processing to make, and wherein thickness is 0.6 cm-1cm.

Preferred described high temperature carbon pole is arranged in the middle of air brick one end, and wherein high temperature carbon element electrode length is 10cm-14cm.

Preferred described breather pipe is that thickness is at the seamless steel pipe of 3mm-5mm.

Preferred described air brick Air permenbility >=200NL/min.

Preferred described safe handling is highly 100mm-140mm.

Compared with prior art, the beneficial effects of the utility model are:

A kind of novel air brick of steel ladle of the present utility model, has the following advantages: 1, safe and reliable, high temperature carbon pole refractoriness is high, not oxidizable and erosion in high-temperature molten steel; 2, simple, the difficult erroneous judgement of operation judges, when the cleaning work of air brick surface, when residual brick height is identical with high temperature carbon pole, high temperature carbon pole is met oxygen combustion and can be sent than bright around flame; 3, cheap, make simple, each cost only several yuans, easily promote.
