Description

Предметом изобретени   вл етс  способ приготовлени  шихты дл  производства минеральной ваты и имеет целью обеспечить однородный химический состав шихты с тем, чтобы у,;1учшить качество минеральной ваты и уменьшить коэффициент теплопроводности.The subject of the invention is a method of preparing a mixture for the production of mineral wool and aims to ensure a uniform chemical composition of the mixture so that,, improve the quality of mineral wool and reduce the coefficient of thermal conductivity.

Дл  получени  однородной-шихты обычно примен етс  предварительпое смепление шлаков и добавок в миксерах.To obtain a homogeneous batch, a preliminary mixing of slag and additives in mixers is usually used.

Особенность предлагаемого способа заключаетс  в том, что сырье, вход щее в состав шихты, измельчают, а затем измельченные и смешанные в нужной пропорции материалы формуют в виде брикетов.The peculiarity of the proposed method is that the raw material included in the mixture is crushed, and then the materials crushed and mixed in the required proportion are molded in the form of briquettes.

Перед брикетированием производ т анализ измельченного сырь  и из него состав.ч ют кислую шихту в пределах модул  1,2™ 2,5.Before briquetting, the crushed raw material is analyzed and the acidic mixture is composed of it within the module 1,2 ™ 2,5.

/(л  легкоплавкости в плихту прибавл ют от 0,25 до 1% полуторных окислов Na2O или и соли железа или марганца./ (l of low melting point, from 0.25 to 1% of Na2O bastard oxides or iron and manganese salts are added to the plicht.

Составленна  шихта формуетс  в брикеты в форме цилиндров высотой 10 см и диаметром 10 см или другие формы аналогичного размера и плавитс  в вагранке.The mixture is molded into briquettes in the form of cylinders 10 cm high and 10 cm in diameter or other forms of similar size and melted in a cupola.

В результате приготовлени  шихты по описанному способу получаетс  однородна  минеральна  вата с элаетичными волокнами, не содержаша  стекловидных включений, с малым объемным весом и низким коэффициентом теплопроводности.As a result of the preparation of the mixture according to the described method, homogeneous mineral wool is obtained with alaetic fibers, not containing vitreous inclusions, with low bulk density and low thermal conductivity coefficient.

Так как брикеты содержат минимальную влажность, то осадка шихты в вагранке происходит равномерно, в то врем  как кусковое сырье, содержащее влагу, доход щую до 40-50%, сильно растрескиваетс  от высокой температуры, образу  при этом трудно разрушаемые своды.Since the briquettes contain minimal moisture, the sediment of the charge in the cupola occurs evenly, while the lumpy raw material containing moisture, reaching 40-50%, strongly cracks from the high temperature, thus forming difficult to collapse vaults.

Предмет изобретени Subject invention

Способ приготовлени  шихты дл  производства-минеральной ваты, отличающийс  тем, что, с одлью получени :однородной по химическому составу шихты, сырье, вход щее в состав шихты измельчают, смешивают в нужной пропорции и формуют в виде брикетов.The method of preparation of the mixture for the production of mineral wool, characterized in that, if only to obtain: homogeneous in chemical composition of the mixture, the raw materials included in the composition of the mixture are crushed, mixed in the desired proportion and formed into briquettes.
