Abstract

Aiming at the problem that the thermal stress of the large rectangular spinning box affects the support, taking the 12-bit biphenyl gas-phase heating large spinning box of a company as the research object, the ANSYS finite element analysis of the whole structure of the rectangular spinning box was carried out, the influence of the support on the temperature variation law of the support was studied, and the thermal stress variation of the support under different external constraints was analyzed. The results showed that the heat dissipation of the support through the support was faster than that in the air. Even if the insulation layer was added to the support and the support surface, there was still a large temperature gradient in the support area. For spinning box, the maximum thermal stress occured at the bolt hole of the box support, the thermal stress at the four corners of the pump seat was more obvious, and the temperature gradient of the spinning box assembly ring was smaller. When the temperature gradient was less than 10℃, the thermal stress of the support was not affected by the change of the constraint.When the engineering design apply, the material with good thermal insulation properties is selected and the ability of bolt tightness is adjusted properly in order to reduce thermal stress and ensure the safe operation of equipment.
