Refractoriness under load: Refractoriness under load is also called high temperature loading initial deformation temperature, which is very important parameter to show the heat resisting of refractory fire bricks.
Thermal shock resistance: Resist the rapid change of temperature without damage.
Compressive strength: The maximum pressure that fire bricks can resist.
Flexural strength: The shear stress that fire bricks can resist.
Linear change rate: Linear change rate is also called linear change on reheating at the same temperature each time.
Basic manufacturing process of Fire bricks for sale in Rongsheng factory: Select the initial point and build base successively from the hot end to the cold end or from low-end to high-end. According to requirement for different material of refractory brick in the hot and cold period, choose qualified firebrick. If there is anchor nails or brick plate, weld them. If there is heat insulation layer (such as calcium silicon plate, etc.), install the insulation mortar first and modulate and use refractory mortar. Match the refractory mortar and fire brick and fill the expansion gap.
Ingredient must meet the requirement of fire bricks for chemical constitution and even has the higher index than firebrick. There is specification of chemical composition for content, fusible total impurities and detrimental impurity quantitative permission of firebricks. Now, fire bricks for sale in Rongsheng factory generally adopt half-dry pressing in the manufacturing process, which require the preform body must have enough associative property. So there must be binding agent in the ingredient.
