Abstract
Description
Изобретение относится к промышленности строительных материалов и касается составов сырьевых смесей для изготовления кирпича, блоков, панелей.The invention relates to the construction materials industry and relates to compositions of raw mixes for the manufacture of bricks, blocks, panels.
Известна сырьевая смесь, содержащая, мас.%: мартеновский шлак 18,7-21,25; конверторный отвальный шлак 1,0-2,5; конверторный синтетический шлак 0,5-2,0; содосульфатная смесь 1,8-2,25; кварцевый песок - остальное /1/.Known raw mix containing, wt.%: Open-hearth slag 18.7-21.25; converter dump slag 1.0-2.5; converter synthetic slag 0.5-2.0; soda-sulfate mixture 1.8-2.25; quartz sand - the rest / 1 /.
Задачей изобретения является повышение прочности изделий из сырьевой смеси.The objective of the invention is to increase the strength of products from a raw mix.
Технический результат достигается тем, что в состав сырьевой смеси дополнительно вводят пиритные огарки, шлам нейтрализации сточных вод производства серной кислоты, известь, при следующем соотношении компонентов, мас.%: мартеновский шлак 18,0-22,0; конверторный отвальный шлак 2,0-3,0; конверторный синтетический шлак 2,0-3,0; содосульфатная смесь 1,8-2,25; пиритные огарки 2,0-3,0; шлам нейтрализации сточных вод производства серной кислоты 1,0-2,0; известь 4,0-6,0; кварцевый песок - остальное.The technical result is achieved by the fact that pyrite cinders, sludge for neutralizing wastewater from the production of sulfuric acid, lime, in the following ratio of components, wt.%: Open-hearth slag 18.0-22.0; converter dump slag 2.0-3.0; converter synthetic slag 2.0-3.0; soda-sulfate mixture 1.8-2.25; pyrite cinders 2.0-3.0; sludge neutralization of wastewater production of sulfuric acid 1.0-2.0; lime 4.0-6.0; quartz sand - the rest.
В таблице приведены составы сырьевой смеси.The table shows the composition of the raw mix.
Для приготовления сырьевой смеси могут быть использованы: мартеновский шлак, образующийся при выплавке стали мартеновским (основным и кислым) способом; конвертерные шлаки, образующиеся при выплавке стали кислым конвертерным способом (на воздушном или кислородном дутье); отвальный шлак, уходящий в отход, и синтетический шлак, который готовят для обработки стали; содосульфатная смесь - побочный продукт производства глинозема на основе двойной соли состава Na2CO3·Na2SO4; пиритные огарки; шлам нейтрализации сточных вод производства серной кислоты состава, мас.%: сера 71-73, известь 0.5-0,7, опока 15-17, шпаты 1-3, каолин остальное; известь, содержащая не менее 93% оксида кальция; кварцевый песок.To prepare the raw material mixture can be used: open-hearth slag formed during steelmaking by the open-hearth (basic and acidic) method; converter slags formed during steelmaking using an acidic converter method (using air or oxygen blasting); waste slag and waste synthetic slag, which is prepared for steel processing; soda-sulfate mixture is a by-product of the production of alumina based on a double salt of the composition Na 2 CO 3 · Na 2 SO 4 ; pyrite cinder; slurry of neutralization of wastewater from the production of sulfuric acid composition, wt.%: sulfur 71-73, lime 0.5-0.7, flask 15-17, spars 1-3, kaolin the rest; lime containing at least 93% calcium oxide; quartz sand.
Подготавливают и дозируют компоненты. Мартеновский шлак, конвертерный отвальный и синтетический шлаки, пиритные огарки, известь размалывают до порошкообразного состояния, смешивают, добавляют содосульфатную смесь, шлам нейтрализации сточных вод производства серной кислоты, воду, еще раз смешивают и выдерживают до полного гашения извести. Из полученной смеси под давлением 15-20 МПа формуют изделия, которые затем подвергают автоклавной обработке в атмосфере насыщенного пара при давлении 0,9 МПа и температуре 175°С в течение 8-14 ч.The components are prepared and dosed. Open-hearth slag, converter slag and synthetic slag, pyrite cinders, lime are ground to a powder state, mixed, sodosulfate mixture is added, sludge to neutralize wastewater from sulfuric acid production, water is mixed again and kept until lime is completely extinguished. Products are formed from the resulting mixture under a pressure of 15-20 MPa, which are then autoclaved in an atmosphere of saturated steam at a pressure of 0.9 MPa and a temperature of 175 ° C for 8-14 hours.
