Description

Высокоглиноземистые огнеупоры имеют большое значение в различных отрасл х промышленности, вследствие повышенной устойчивости к расплавленным реагентам. Однако они не имеют достаточно высокой термической стойкости, что снижает эффективность их использовани .High-alumina refractories are of great importance in various industries, due to their increased resistance to molten reagents. However, they do not have a sufficiently high thermal stability, which reduces the efficiency of their use.

В предлагаемом способе этот недостаток уст|ранен тем, что при изготовлении высокоглиноземистых огнеупо;ров вводитс  в шихту добавка мелкозернистого карборунда в виде порошка с размерами зерен не крупнее 0,2 мм. Карборунд вводитс  в количестве от 3 до 18%, что обеспечивает повышение термической стойкости высокоглиноземистых огнеупоров .In the proposed method, this disadvantage is caused by the fact that in the manufacture of high-alumina refractory material, the addition of fine-grained carborundum in the form of a powder with a grain size not larger than 0.2 mm is introduced into the mixture. Carborundum is introduced in an amount of from 3 to 18%, which provides an increase in the thermal resistance of high-alumina refractories.

Основна  часть шихты по указанному способу содержит в Ka4ecTBt наиолнителей корунд или корундомулллт или муллит, а в качестве св зки - примен етс  смесь из технического глинозема и огнеупорной глины .The main part of the mixture in this method contains kaundum or korundomullt or mullite in Ka4ecTBt of nuclei, and a mixture of technical alumina and refractory clay is used as a binder.

Наполнители могут быть природными или искусственными.Fillers can be natural or artificial.

Предлагаемый способ используетс  преимуш,ествеипо при изготовлении огнеупорных фурм к сталеплавильным конверторам с воздушным или кислородным дутьем.The proposed method is used primarily in the manufacture of refractory tuyeres to steel-making converters with air or oxygen blast.
