For reaching above-mentioned technique effect, the utility model adopts following technical scheme: a kind of SO
3the sliding type base of convertor, comprises connection bracket, supporting leg, base assembly, guide plate, sliding block, top shoe and pressing plate, the fixing welding in connection bracket and supporting leg top, supporting leg bottom welding top shoe; Platen width is greater than guide plate, and pressing plate, guide plate and base assembly from up to down set gradually the cavity that forms an indent, and cavity open top width is less than housing width, and sliding block contacts and is arranged in described cavity with top shoe.
Preferably, uniform 20 graphite blocks, described graphite block ultimate compression strength P > 50MPa, 200 ℃ of heat resisting temperature >, the Shore hardness 40～55 of being no less than in described sliding block top.
Preferably, the connection section of described graphite block and sliding block is that tetrafluoro powder forms through high temperature compacting.
Preferably, described supporting leg is circular tube shaped, at least four fins of arranged outside.
Preferably, during use, convertor bottom is fixedly connected with a plurality of SO
3the sliding type base of convertor, described SO
3the sliding type base of convertor distributes radially around convertor center, and the spacing between sliding support is 1750mm.
The beneficial effects of the utility model:
The utility model provides a kind of SO
3the sliding type base of convertor, during use, convertor bottom is fixedly connected with a plurality of SO
3the sliding type base of convertor, described SO
3the sliding type base of convertor distributes radially around convertor center, and when convertor is during due to thermal expansion or cooling generation thermal stresses, stress impels SO
3the top shoe of the sliding type base of convertor moves forward and backward to eliminate thermal stresses; protection conversion body and base plate be not by drawing crack, and graphite block, at sliding process lubricate, is that tetrafluoro powder forms through high temperature compacting under graphite block; there is certain elasticity, the levelness of adjustable graphite block.
