[Abstract]:Rolling is the main project in the iron and steel industry and nonferrous metal products industry. The production process layout is complex, the electric equipment is numerous in the hot mill workshop, and the flammable liquid and power cable are used extensively. Once the fire occurs, the danger is very high.The production enterprises often choose fire-proof cloth to protect the fire safety of production equipment and facilities.In this paper, the concrete application scheme of passive fire-proof system of power cable in hot mill workshop is studied by means of conical calorimeter experiment and solid fire experiment. In this paper, five kinds of commonly used flame-proof fabric asbestos fiber fire-proof cloth are selected in conical calorimeter experiment.Ceramic fiber fire proof cloth, silica gel fire proof cloth, coated fire proof cloth and carbon fiber fire proof cloth were used to study the effect of different radiation intensity on the burning performance of fire proof cloth by cone calorimetry.Reaching 272.59 kW / m2, the peak value of effective combustion heat is also the highest, reaching 529.52 KJ / g. The combustion performance of each sample is compared synthetically.The order of fire resistance is silica gel flame-proof cloth, asbestos fiber, fire-proof fabric, ceramic fiber, fire-proof cloth, carbon fiber, fire-proof cloth. 2. Solid fire experiments are conducted to study different types of fire prevention in hot rolling mill workshop by means of solid fire experiment.The specific application of fire cloth to power cable wrapping: through pre-experiment,The results show that the flame temperature of heptane is higher than that of hydraulic oil flame, but the temperature of inner layer of fire proof cloth is the same, and the experimental time is 5min, compared with that of hydraulic oil pool fire, the flame temperature of heptane is higher than that of hydraulic oil flame.The protective effect of the cable is consistent, and the temperature rise is similar to that of the fire resistant cloth with a thickness of 0.6 mm. In the case of the same coating thickness, the effect of wrapping and protecting the cable can be realized within 300 s. In the three kinds of fire-resistant cloth with the same thickness,The encapsulation performance of asbestos fiber and ceramic fiber fire proof cloth is better than that of silica gel fire proof cloth.Through the formal experiment, the order of the five kinds of fire-proof cloth is ceramic fiber fire-proof cloth, asbestos fiber anti-fire cloth, silica gel anti-fire cloth, carbon fiber anti-fire cloth, adhesive fire-proof cloth.When the outer layer is not brushed with oil, the coating performance of silica gel fire proof cloth (inner layer) ceramic fiber (outer layer) is the best: when the outer layer is brushed,Asbestos fiber fire-proof cloth (inner layer) silicone fire-proof cloth (outer layer) wrapping performance is optimal.Through the research of this paper, in the actual production application, the fire proof ability of silica gel fire proof cloth, asbestos fiber fire proof cloth and ceramic fiber fire proof cloth is stronger, and in the workshop where the machine oil leakage is less,The coating performance of silica gel fire proof cloth (inner layer) ceramic fiber fire proof cloth (outer layer) is the best, and the asbestos fiber fire proof cloth (inner layer) silicone fire proof cloth (outer layer) is the best in the workshop where the machine oil leakage is more.This study can provide guidance and reference for the same type of production enterprises to set up passive fire-proof system.
