Furnace shell winter welding heat preservation shed and construction protection method thereof
The invention relates to a furnace shell winter welding heat preservation shed. The furnace shell winter welding heat preservation shed comprises a shed roof formed by connecting a plurality of trusses through a center point and further comprises windproof tarpaulin hung to the welding position of a furnace shell from the top of the shed roof, and the lower end of the windproof tarpaulin is connected with a welding operation platform in a sealed mode. The invention further provides a method for protecting construction by combining the furnace shell winter welding heat preservation shed. The method comprises the steps that windproof tarpaulin is hung on the top of the heat preservation shed from top to bottom, and the lower end of the windproof tarpaulin is tightly sealed with the welding operation platform; a fan heater is installed in the windproof tarpaulin to heat the interior of the heat preservation shed; ceramic heating equipment is installed along a welding seam to conduct preheating and postweld heat treatment on a welded junction; and the fan heater and the ceramic heating equipment are connected with the power distribution system and are powered by the power distribution system for heating. According to the method, the welding position of a blast furnace is well separated from the external environment, the severe influence of cold air on the temperature change of a welding seam is reduced, the problem of incomplete stress release of the welding seam is avoided, and the welding quality requirement is met.
本发明涉及一种炉壳冬季焊接保温棚，包括由若干桁架以中心点相连组成的棚顶，还设有自棚顶顶部悬挂至炉壳焊接位置的防风苫布，防风苫布下端与焊接操作平台密封连接；本发明还提供了结合上述炉壳冬季焊接保温棚对施工进行保护的方法：将防风苫布由上而下悬挂至保温棚顶上，下端与焊接操作平台密封严实；在防风苫布以内安装暖风机进行保温棚内加热；沿焊缝安装陶瓷加热设备对焊口预热以及焊后热处理；暖风机和陶瓷加热设备与配电系统相连，通过配电系统供电加热，本发明将高炉焊接位置与外部环境很好的分隔，减少了冷空气对焊缝温度变化的剧烈影响，避免焊缝应力释放不完全的问题，保证了焊接的质量要求。
