Device heats, and it is that temperature difference at the top and bottom of tank body is huge that this mode, which heats greatest problem, in process of production due to
Although sizing material inside has agitator stirring in tank body, bottom of most of sizing material all in tank body, and the top in tank body
It is empty, so heat is sent in sizing material by the steel plate of tank body during the bottom hot plate heating of tank body in heating process
Go, and heat can only be radiated the steel plate of tank body, the heat being sent to by steel plate in tank during heater plate at the top of tank body
Seldom, design temperature just so can not be arrived into tank base, tank body head temperature substantially exceeds design temperature, even up to
More than 600 degree, so production causes the material generation change life of tank body steel plate for a long time, when material changes to a certain extent
When, tank body steel plate is acted on by pressure inside the tank, and tank body steel plate locally plays drum deformation, and damage is scrapped, and very big warp is caused to enterprise
