A process unit is a device in which one of the operations that constitutes a process is carried out. Each process unit has associated with it a set of input and output process streams, which consists of ...Requirements of refractories are various and decided by the furnace working condition and actual atmosphere. But they should character with these features: high temperature resistance, good chemical stability and anti-corrosion, thermal shock resistance, volume stability, mechanical strength. SIJIHUO REFRACTORY can supply all related refractory ...Two type of refractory concrete materials are used for lining of heating equipment: lightweight and medium-weight. 4.16.7 Lightweight (LW) Concrete Lightweight (LW) concrete should be a mixture of calcium aluminate cement with aggregates (e.g., perlite, vermiculite, blast-furnace slag, clay, diatomite, fly ash, shale, or slate).This is a high - performance material, where the person who is assigned as the nozzle man for this purpose must gain great skill and dedication in the application. Aplete rely on the machine and the sprayed concrete is ensured, as this is a " threeponent success", i.e. man, machine, and concrete.
