Detection and analysis of gas tightness of continuous annealing furnaces

Baosteel Technical Research 2008年第1期2卷 41-45页

作者： Hu Guangkui Song Ruhua Cold Rolling Plant Baosteel Branch Baoshan Iron ＆Steel Co. Ltd. Shanghai 200941 China

When a cold rolled strip is being treated in a continuous annealing furnace which is full of protective gas, the gas tightness of the furnace body, the connected facilities and the gas channels become an important indicator that directly affects the product＇s surface quality and shows the technical level of the design, the manufacture and the installation. By considering the problems of the gas tightness of a vertical annealing furnace in the installation and maintenance, this thesis evaluates the gas tightness indicator and gas tightness related level of the furnace body and the circulation duct, while studying and analyzing the technologies of negative-pressure leak detection and sealing.

Aiming at the requirement of the full-ocean-depth(operating water depth 11000 m)manned submersible to carry out the gas-tight sampling operation of the abyss seabed sediment,a kind of full-ocean-depth carrier submersible mechanical hand-held,full-ocean-depth gas-tight sediment sampler(GTSS)with the function of pressure-retaining and coring is ***,the volume change model of pressure compensator is established,and it is pointed out that the volume of pressure compensator is about 16.14%equal to the volume of gas-tight sediment sampler(GTSS).Secondly,the pressure compensator is analyzed and calculated,and the relationship between the precharge pressure of the pressure compensator,the nominal volume of the pressure compensator and the pressure holding effect of the gas-tight sediment sampler(GTSS)is *** results show that with the increase of gas precharge pressure in the pressure compensator,the final pressure of the sampler also *** the same precharge pressure condition,the larger the nominal volume of the pressure compensator,the greater the final pressure of the ***,the air tightness test method is designed by using the developed gas tightness sampler of the full-ocean-depth product,and the change of the final pressure in the gas tight sampler under different precharge pressure is *** test results are consistent with the simulation results,indicating the correctness of the pressure compensation system(PCS)model.
