Construction method of refractory material lining for Indefinite shape
In the process of using some industrial furnaces, it is often necessary to use some refractory materials for lining to make the continuous operation of the furnace be safe, reliable and long-term. And in the furnace lining construction process of general industry kilns, the use of refractory materials with indefinite shape is relatively large.
Indefinite shape refractory material lining construction is a technical process of identifying and summarizing the space of indefinable shape cavity according to certain rules, filling refractory material and leveling it. This kind of construction is the most model, difficult and key point of the whole furnace lining. Its construction must be carried out by professionals, and all can not be sloppy and perfunctory, otherwise it will affect the service life of the whole industrial furnace.
Generally speaking, this kind of construction can be divided into three steps, that is, observe and measure, fill and modulate. 1. Observations and measurements. Observing the surface and taking the measurements for the datum plane, maximum and minimum surface and joint points of the indefinite shape cavity surface could ensure the accuracy of the measurements. Professional workers often use two parts: one part is about the infinity shape that the refractory material contact with, and the other part is about the refractory material contact with the other surface which it should not touch.
2. Fill and modulate. The area of indefinable shape cavity is filled and leveled according to the measurement result. It is worth noting that, refractory material should be filled and levelled in one layer. And if this condition cannot be reached, then it is necessary to lay insulation bricks, insulation fiber, insulation felt, etc., as the spacer layer of refractory material. In this way, refractory material could fill the indefinite shape space better, and the levelling could also be controlled more accurately.
3. Pack. After the refractory material of the indefinite shape cavity is filled, it need to be compacted and leveled by certain tools, such as tamping bars, shovels, iron rammers and so on, so that the filled material is firmly combined with the original surface, and the entire infinite shape refractory material lining construction process could also be completed.
The construction of indefinite shape refractory material lining, not only to ensure the absolute safety of the continuous operation of the furnace, but also to ensure that the furnace can be used for a long time without damaging. Therefore, it is necessary to ensure that the professionals and relevant process requirements are strictly adhered to, so as to ensure the long-term and safe operation of the entire industrial furnace and its equipment.
