The thermal stress damage of enamel reaction tank
Addtime：2016-10-19 14:30:19 Print
The company mainly engaged in enamel reaction tank and other products, here small make up to introduce you to:
Enamel reaction tank by 900 ℃ high temperature roasting, enamel with bonding steel plate after cooling.Due to the linear expansion coefficient of enamel and elongation rate is less than steel, so the cooling of glass lining deformation after less than the deformation of the steel plate, enamel will produce a compressional stress constraint by steel plate.Made of enamel reaction tank, the glass lining is compressive stress, while the plate is tensile stress.Because of prestressed associated with linear expansion coefficient and elongation, linear expansion coefficient and the elongation is closely related to the temperature and, therefore the working temperature of enamel reaction tank had a great influence on the use of enamel reaction tank.If because of the temperature change is big and make the enamel stress over its use stress, enamel will be destroyed.So the enamel reaction tank enamel layer in cold and hot leaps, and explosive porcelain.So the enamel reaction tank and heat-resistant limitation: temperature 200 ℃, heat-resistant snap: cold shock < 1 IO ~ C, thermal shock < 120 ℃.When feeding material temperature and tank temperature difference is too big, and heating steam is too hard, cooling can also lead to porcelain.So the pot in the use of, cooling slowly rise, uniform, hierarchical cooling.
Saw so much of the knowledge, hopes to be helpful for your life in the future work, we welcome your visit at any time.
