Background technique
When cast tube industry production ductile iron pipe is cast at present, the end of bellmouth is stifled, and use is all sand core.But in the casting of pipe
It makes link and does not all carry out residual core thorough cleaning, such as can form residual sand in high annealing without thorough cleaning and stay in annealing furnace
It is interior, give annealing furnace band very big unfavorable factor.Existing joint-stock company Wuan industrial area our department, ductile iron pipe production are more than 20 years existing
But the residual sand of the cast tube sockets produced after being centrifuged manually purges always, artificial to purge large labor intensity position and before annealing furnace
Environment is extremely hot.Due to large labor intensity, environment is extremely hot, and one, the post people that blows sand can not adhere to a class.Stokehold is blown sand work at present
Everyone half an hour one changes shifts with two people of stokehold room operation, substitutes dry；Work of blowing sand simultaneously is often scalded by the hot sand of splashing.Simultaneously
Every pipe must be purged again, now urgently need to carry out technology and equipment to equipment of blowing sand before cast tube portion annealing furnace
Innovation, it is arduous gradually to get rid of cast tube portion worker's operating condition, is not easy the image advertised for workers.
