Изобретение относитс к промышленности строительных материалов. Оно может быть .использовано нри лроизводстве изделий из легкого жаростойкого бетона, в частности, изделий на основе алюмофосфатной сырьевой смеси.This invention relates to the building materials industry. It can be used in the manufacture of products from light heat-resistant concrete, in particular, products based on aluminophosphate raw mix.
Известны способы изготовлени .изделий на осно.ве алюмофосфатной сырьевой смеси путем укладки смеси в формы, первичного обжига , охлаждени , |распалубки и ловторНого обжига.There are known methods for the manufacture of articles based on alumophosphate raw material mixture by laying the mixture into molds, primary calcination, cooling, demolding and catcher calcining.
Недостатком этих способов вл етс длительность цикла изготовлени изделий (от 8 до 57 час к зависимости от толщины изделий). The disadvantage of these methods is the duration of the cycle of manufacture of products (from 8 to 57 hours, depending on the thickness of the products).
Целью изобретени вл етс сокращение технологического-цикла и повыщение качества изделий.The aim of the invention is to reduce the technological cycle and improve the quality of products.
Это достигаетс тем, что форму предварительно нагревают в печи до температуры первич .ного обжига и .производ т укладку смеси последовательно по -порци м после затвердевани каждой предыдущей порции.This is achieved in that the mold is preheated in the kiln to the primary calcining temperature and the mixture is stacked sequentially in portions after the solidification of each previous batch.
Способ осуществл ют следующим образом.The method is carried out as follows.
Металлическую фОрму дл изготовлени изделий помещают в печь, нагревают до 250- 300° Сив -нее через отверстие в печи подают заранее приготовленную алюмофосфатную смесь, например смесь тонкомолотого корунда и ортофосфорной кислоты. За счет температуры окружающей среды и формы увеличиваетс степень вспучивани смеси и скорость ее затвердевани .A metal mold for the manufacture of products is placed in a furnace, heated to 250-300 ° Civ-more, a previously prepared aluminophosphate mixture, for example, a mixture of finely ground corundum and phosphoric acid, is fed through an opening in the furnace. Due to the ambient temperature and the shape, the degree of swelling of the mixture and the rate of its solidification increase.
Скорость подачи смеси и укладки ее в форму выбирают таким образом, чтобы вспучива .ние И затвердевание уложенных в форму порций смеси происходило раньще подачи последующих порций. После заполнени формы и затвердеван.и смеси форму с изделием охлаждают и распалубливают. Затем издели The feed rate of the mixture and its laying in the form is chosen in such a way that the swelling and hardening of the portions of the mixture laid in the form take place earlier than the supply of subsequent portions. After filling the mold and hardened, and the mixture, the mold with the product is cooled and disintegrated. Then the product
подвергают повторному обжигу при 500- 600° С по известным режимам.subjected to re-firing at 500-600 ° C according to known conditions.
Объемный вес изделий, изготовленных но описываемому способу составл ет 400- 1200 кг1м (.в зависимости от состава), прочность при сжатии 14-150 кг1см, огнеупорность 1выще 1700° С.The volumetric weight of products manufactured using the method described is 400-1,200 kg1 m (. Depending on the composition), compressive strength 14-150 kg1 cm, fire resistance 1 higher than 1700 ° C.
Предмет изобретени Subject invention
Способ изготовлен.и изделий на основе алюмофосфатной сырьевой смеси .путем укладки смеси в формы, первич.ного обжига, охлаждени , распалубки и повторного обжига, отличающийс тем, что, с целью сокращени технологического цикла и повыщени качества издел.ий, форму предварительно нагревают в печи до темлературы первичного обжига и производ т укладку смеси последовательно по порци м .после затвердевани каждой лредыдущей порции.The method is manufactured and products based on an aluminophosphate raw material mixture. By placing the mixture in molds, primary calcination, cooling, demolding and re-calcining, which is used to preheat the mold to reduce the production cycle and improve the quality of the products kilns before primary firing and the mixture is stacked sequentially in portions after solidification of each previous batch.
