Lightweight clay insulation refractory brick detailed index
Light insulation and refractory brick detailed description of the introduction and clay brick insulation refractory brick parameters - Henan Li Te Refractories Co., Ltd.
In the double-sided radiant heating furnace, the flame attached to the furnace wall of the furnace is the refinery hydrogenation device in the common furnace, the flame burner burned by the hot furnace wall of the radiant chamber tube heat radiation, So as to ensure that the furnace tube heat evenly. Flame attached to the wall using refractory bricks, ordinary refractory tiles difficult to withstand the temperature of the flame and the temperature of the thermal operation of the thermal shock.
Refinery hydrogenation device in the reaction feed furnace is the main source of heat in the device, the hydrogenation reaction feed furnace tube for the gas-liquid two-phase flow, engineering design, the use of horizontal double-sided radiation box furnace. In order to ensure that the furnace tube heat evenly, the type of work often used flat flame attached to the wall burner, flame attached to the wall burning, and then by the hot furnace wall of the furnace tube for thermal radiation. But the actual production found that the furnace temperature operation on the refractory material and large thermal shock, refractories must have excellent thermal shock stability, otherwise it will cause the furnace wall cracking, resulting in serious heat loss, and even threaten the production safety The
Industrial furnace furnace block heat loss and furnace surface heat loss, generally about 24 to 45% of fuel consumption. At the same time, because the furnace can quickly heat up and cooling, can improve equipment production efficiency; also reduce the weight of the furnace, to simplify the furnace, the furnace can be used to reduce the fuel consumption. Construction, improve product quality, reduce the ambient temperature, improve working conditions. However, lightweight refractory bricks have large porosity, organized
Dredge, can not be used for direct contact with slag and liquid metal parts. Mechanical strength is low, can not be used for load-bearing structure; wear resistance is poor, not suitable for contact with the charge, wear serious parts.
Light insulation refractory bricks of the type and manufacturing process Light insulation refractory bricks within the porous structure with thermal insulation properties of block insulation refractory products, with the brick production and application of the most widely, it is also known as light Quality insulation refractory bricks. The common feature of this kind of material is the small bulk density, light weight, low thermal conductivity. But the strength is low, high temperature heavy burning shrinkage larger. Lightweight refractory bricks have low compressive strength, poor slag resistance, poor thermal shock resistance, and can not work with glass
direct contact.
