High aluminum castings, also known as refractory castable, by refractory aggregate, powder, binder, admixture, etc. It has high mechanical strength, good thermal shock resistance, wear resistance and other characteristics, mainly used for boiler, blast furnace, heating furnace, ceramic furnace lining.
Refractory castable is a kind of granular powder material made of refractory material, which is combined with a certain amount of binder and water. It has high fluidity and is suitable for castable construction without the need for heat to make shapeless refractories. Consists of refractory aggregate, powder, binder, admixture, water or other liquid materials.
It is usually used in the field casting, vibration or tamping, can also be made into prefabricated parts. During construction, a certain amount of water (or a solution containing a binder) is added, stirred and cast, and then cured and solidified. Materials and adhesives can be selected according to the conditions of use.
Casting material is the most widely used refractory material, used for the construction of various furnace lining of the overall structure, can be used in smelting furnace. Aluminate cement and other castings can be widely used in various heating furnaces and other slag - free, acid - base erosion thermal equipment. In molten iron, molten steel, slag erosion, high working temperature, such as steel outlet, ladle, blast furnace body, steel outlet, etc.
Can be widely used in heating furnace and heating metal furnace, can be used in coke oven and cement kiln. In metallurgical furnaces and other containers in direct contact with slag and molten metal, the use of high-quality phosphate castings can also play a better role. In some parts where the working temperature is not high and high wear resistance is required, it is more appropriate to use phosphate castable. If corundum castable is selected, the refractory generally has better effect in reducing gas points.
Mainly used for the construction of various heating furnace lining. Some high quality varieties can also be used in smelting furnace. Refractory castable as thermal equipment and furnace lining, generally should be baked before the first use, in order to make the physical water and crystal water gradually eliminate, to a certain degree of sintering, when the use of stable state, its size and performance has been improved.
The baking system has great influence on the service life. The basic principle of the baking system should be the possible dehydration temperature and its content corresponding to the phase change and deformation, in a certain temperature stage these rapid changes should be slow heating and holding time. If baked improperly or heated immediately, it can be quickly heated and put into use, easily leading to serious cracks or even loose collapse. It could even explode in the thickest part of tebente.
