Description
В мешалку налившэт воду, добавл ют огнеупорную глину и сульфиднодрожжевую бражку. Полученный раствор св зующего перемешивают в течение 2-3 мин, затем при работающей мешалке добавл ют алюмохромосиликатное волокно. После получени однородной гидромассы добавл ют полиакрилаилид и снова перемешивают 2-3 мин. ГидроСодержание компонентов, вес.%Refractory clay and sulphide yeast mash are added to the mixer. The resulting binder solution is stirred for 2–3 minutes, then the aluminum chromosilicate fiber is added while the mixer is running. After a homogeneous hydromass is obtained, the polyacrylamide is added and mixed again for 2-3 minutes. Hydrocontent of components, wt.%
СоставComposition
массу подают в форму пневмопресса, где формуют издели методом подпрессовки с вакуумироВ1анием: давление прессовани 0,3-0,5 МПа, разрежение 0,02-0,03 МПа. Сушку изделий провод т при 90-150 С в течение 12-18 ч.the mass is fed into the form of a pneumatic press, where the products are molded by the method of pressing with vacuuming: a pressing pressure of 0.3-0.5 MPa, a negative pressure of 0.02-0.03 MPa. Drying of products is carried out at 90-150 ° C for 12-18 hours.
Составы предлагаемой и известной КОМПОЗИЦИЙ указаны в табл. 1.The compositions of the proposed and known compositions are shown in Table. one.

У полученных изделий определ ют ка)пущуюс плотность, предел прочности при изгибе, а также проникновение окалины после выдержки изделий в течение 24 ч при 1400с. Дл этого вырезают кубики 50x50x50 мм, в центре которых просверливают отверстие диаметром 15 мм на глубину 30 мм. For the obtained products, they are determined for the density, flexural strength, and scale penetration after holding the products for 24 hours at 1,400 s. To do this, cut cubes 50x50x50 mm, in the center of which a 15 mm diameter hole is drilled to a depth of 30 mm.

В отверстие засыпают тонкоизмельченную окалину, кубики помещают в печь и нагревают до . После обжига кубики разрезают и измер ют проникновение окалины в миллиметрах.Finely ground slag is poured into the hole, the cubes are placed in the oven and heated to. After firing, the cubes are cut and the scale penetration in millimeters is measured.
