Heat insulation refractory is a kind of heat insulation refractory commonly used in industrial kilns and thermal engineering equipment when the requirements of heat insulation and heat preservation need to be solved. How to select and use heat insulation refractory reasonably and efficiently according to the working condition and environment, so as to obtain the best energy-saving effect and the best cost performance? Let's analyze it together.
When selecting thermal insulation refractory materials, the following situations need to be analyzed:
(1) The operating temperature of the equipment, i.e. the highest temperature service value and insulation performance value of the insulating refractory required by the equipment;
(2) The highest use temperature of thermal insulation material, that is, the safest use temperature of thermal insulation refractory material itself;
(3) Performance indexes of thermal insulation refractory (thermal insulation performance, thermal conductivity, bulk density, specific heat, hot melt, etc.), It should be noted that the selection of bulk density of thermal insulation refractory materials and the thermal insulation performance of thermal insulation refractory materials increase with the decrease of bulk density. Generally speaking, from the perspective of energy saving, the user manufacturers tend to choose low-density thermal insulation refractory materials, but the production cost of low-density thermal insulation materials is high, and the cost performance is poor. According to the actual experience, the production cost of low-density thermal insulation materials is high In the selection of thermal insulation materials, we should not only pursue low density, but also choose the appropriate density of thermal insulation refractory materials according to the working environment and use temperature to achieve the best energy-saving effect and cost performance.
(4) With the development of refractory manufacturers' technology, a considerable number of manufacturers will use the thermal insulation refractory as the working lining of thermal kilns when they choose to use the thermal insulation refractory. In many heat treatment furnaces and sintering furnaces, in order to improve the quality and efficiency of their products, they often operate Using various protective atmosphere will also affect the service life and cycle of thermal insulation materials.
In the reasonable selection of thermal insulation and refractory materials, in addition to the above points that need to be understood, there are also situations that need to be paid attention to such as the physical and chemical properties of thermal insulation materials. As a professional thermal insulation material manufacturer, Lu'an green energy refractory Co., Ltd. will carefully select the cost performance ratio for customers in terms of economic benefits, price, construction difficulty and durability of thermal insulation materials The highest insulating refractory.
