广州柴油机厂铸造车间,冲天炉因用焦质劣,熔炼初期铁水温度低、流动性差,出铁口易被铁水结死;熔炼过程中渣多且稠,流动性差,出渣口极易堵塞。一旦发生出铁口结死、出渣口堵塞故障时,必须靠人力打通,劳动强度大、条件恶劣。有时甚至被迫停炉,影响生产正常进行。为解决此问题,该厂将冲天炉前炉出铁口砖的安装位置做了如图1所示的改进。 Guangzhou diesel engine factory foundry, cupola due to the use of poor quality, low temperature molten iron in the early days of melting, poor liquidity, taphole easily molten metal knot die; smelting process more and more thick, poor liquidity, easy to plug the tap hole. In the event of taphole knot death, tap hole blocking failure, must rely on human open up, labor-intensive, harsh conditions. Sometimes even forced to shut down, affecting the normal production. In order to solve this problem, the factory made the improvement of the installation position of the cupola taphole brick in the cupola furnace as shown in FIG. 1.
