First of all, we must grasp the working conditions of the site, know its working temperature, limit temperature and other factors that affect normal work, such as particulate matter, humidity, pressure, insulation...
Each working condition has its focus on protection. The focus of the cast steel industry is high temperature. Because of the particularity and inevitability of the industry, it is indispensable to deal with various high temperature environments during daily work, which makes some equipment always in the same position. In a dangerous environment, for example, many industries now use electric energy as energy to provide power, and electric energy can only be conducted through cables, and its normal operating temperature is much lower than the temperature in a cast steel environment. At this time, we It is necessary to take a protective measure for the line to ensure its normal operation
At present, the conventional protection is mainly made of glass fiber sleeve woven with high bulky glass fiber and coated with imported high-quality silicon rubber. The silicon rubber glass fiber heat-resistant sleeve can block molten iron, molten copper, and molten iron. Splash of aluminum, etc., and is not damaged by high temperature and flame. The imported alkali-free glass fiber cloth with high-strength and wear-resistant aluminum base layer is used as the base material. Different specifications and sizes can be made according to the specific environment. The folds are double stitched with high temperature resistant sewing threads to ensure the overall strength of the casing during installation and the stability coefficient under high temperature environments.
When choosing heat-resistant casing, fire-resistant casing, and heat-insulating casing, it is best to take a part of the sample and cut it to see the glass fiber inside.
Most of the glass fibers in the heat-resistant casing, fire-resistant casing, and heat-insulation casing are white. A few glass fibers are milky white or light yellow. According to its color and outer layer of silica gel, it is judged whether it is produced by a regular manufacturer. Many manufacturers In order to save costs during production, some other substances will be mixed into the glass fiber, which will greatly affect the insulation effect and service life of the casing.
High-temperature resistant casing, fire-resistant casing, and heat-insulating casing because its surface is made of imported high-quality silicone rubber, so it has the characteristics of dustproof, waterproof and easy to manage. Its working temperature is 260℃, which is suitable for most working conditions. It can withstand 5-10 minutes at a temperature of 1090°C, adapting to a short-term high temperature environment, and at a high temperature of 1650°C, it can withstand 15-30 seconds, prolonging the discovery and handling process in emergencies.
On the premise of meeting the requirements of working conditions, the high-temperature casing, fire-resistant casing and thermal insulation casing has made many changes on the original basis, such as shape, installation method, color, material and so on.
