Description

(54) ОГНЕУПОРНАЯ МАССА(54) REFRACTORY MASS

ка разм гчени  141°С) и 2% хлопьевидной хромовой кислоты смешивают с 92% магнезита со следующим составом: 97,2% MgO, 0,8% СаО, 1,2% Si02, 0,4% FegOs и 0,4% .softening 141 ° C) and 2% flaky chromic acid is mixed with 92% magnesite with the following composition: 97.2% MgO, 0.8% CaO, 1.2% Si02, 0.4% FegOs and 0.4% .

Размер зерен магнезита, имеющего зернистую пористость 8,0%: 60% не более 6,35 мм; не менее 20% 0,044-0,149 мм и 20% не более 0,044 мм. Такую гомогенную смесь подают в нневматический пистолет и при прохождении смеси через сопло пистолета добавл ют 6% воды, которые смешивают с 94% сухой смеси. Врем  установки смеси 20 мин, а полное затвердевание массы происходит через 15 мин после окончани  установки. Плотность материала равна 2530 кг/м а содержание остаточного углерода 4%. Материал выдерживает 65 нагревов, а износ составл ет 3,75 мм на 1 нагрев.The grain size of magnesite having a granular porosity of 8.0%: 60% not more than 6.35 mm; not less than 20% 0.044-0.149 mm and 20% not more than 0.044 mm. This homogeneous mixture is fed to a pneumatic gun, and as the mixture passes through the nozzle of the gun, 6% water is added, which is mixed with 94% of the dry mixture. The setting time of the mixture is 20 minutes, and the complete solidification of the mass takes place 15 minutes after the end of the installation. The density of the material is 2530 kg / m and the content of residual carbon is 4%. The material withstands 65 heats and the wear is 3.75 mm per heat.

Монолитный огнеупорный материал подходит дл  установки как в гор чие, так и в холодные емкости. Если материал помещают в холодную емкость, то поскольку он включает в себ  твердеющую на воздухе св зку, то дл  получени  необходимой прочности и твердости не требуетс  нагрева. Если материал помещают в гор чую печь, тепло будет удал тьThe monolithic refractory material is suitable for installation in both hot and cold containers. If the material is placed in a cold container, since it includes an air hardening bond, heat is not required to obtain the necessary strength and hardness. If the material is placed in a hot oven, heat will be removed.
