Analyze the effect of coil cement products

 Today, Luoyang Quantong Kiln Industry Co., Ltd. will show you what are the special advantages of using coil insulation cement?

1. After drying, the coil insulating mastic layer with a thickness of 8-15mm has a good insulating function, which can completely replace mica and glass wool cloth and act as an insulating protection layer between the coil and the furnace lining; the thermal conductivity of the mastic material is high. Concerned that a relatively thick layer of cement will affect the 3-layer junction of the hot-face lining;

2. The cement layer is located between the coil and the insulation layer. Under normal circumstances, the ambient temperature is very low (<300 degrees="" celsius.="" when="" the="" metal="" liquid="" approaches="" its="" surface="" occasionally,="" a="" small="" amount="" of="" residual="" moisture="" will="" be="" released="" from="" the="" cement="" layer,="" which="" will="" reduce="" the="" insulation="" resistance="" and="" supply="" the="" system.="" early="">

3. Using the refractoriness of the cement itself higher than 1800 degrees Celsius, when there is occasional leakage of metal liquid to its surface, the cement can provide a protective barrier to the coil, and when an alarm occurs, the cement layer can provide a certain time for accident handling;

4. For the furnace with bottom top-out type, the cement is made into a tapered shape to avoid the friction between the furnace lining and the coil, and at the same time, the coil is fixed by its strength, which avoids the use, construction and dismantling of the coil. The deformation during the furnace process prolongs the service life of the coil.

5. The coil and the cement layer are used as the permanent fire lining of the furnace. Although the one-time cost is high and the construction period is long, its service life can be the same as that of the coil, and local repairs can also be carried out, thus reducing the cost of building the furnace as a whole.

Before dry knotting the furnace lining, first lay a layer of asbestos board and a layer of glass fiber cloth in the insulation layer of the furnace coil. When laying, in addition to manually compacting the layers of materials, spring coils should be used to tighten up and down, and the quartz sand should be tamped. When the furnace lining is finished, move the spring coils one by one from top to bottom until the lining is knotted.
