Annular heating furnace large soleplate adopting rolled blank and manufacturing method thereof

Abstract

The invention relates to an annular heating furnace large soleplate adopting a rolled blank, and the annular heating furnace large soleplate is characterized in that a body of the large soleplate is a disk structure, one side surface of the disk structure is a plane, the center on the other side of the disk structure is a plane, the periphery of the plane is a conical surface, the center of the large soleplate is provided with a central hole, an annular lug boss is arranged around the central hole, and the blank of the large soleplate is a rolled blank. The large soleplate is made of heat-resistant stainless steel, the heat-resistant stainless steel is cast by a steel die into a cast blank, the cast blank is rolled into a rolled plate after the solution treatment, after rough mechanical machining and fine mechanical machining, the rolled plate is nondestructively examined, and a product passing through the nondestructive examination is a large soleplate finished product. According to the annular heating furnace large soleplate adopting the rolled blank and the manufacturing method thereof, the characteristics of a rolling process can be utilized to improve the structure of the blank, so that the high-temperature strength and the high-temperature stability of the annular heating furnace large soleplate can be greatly improved, the working requirement of an annular heating furnace can be met, and the effect is remarkable.

Description

technical field [0001] The invention relates to a large bottom plate of an annular heating furnace and a manufacturing method thereof, in particular to a large bottom plate of an annular heating furnace using a rolled blank and a manufacturing method thereof. Background technique [0002] The ring heating furnace is the heating equipment for heating the workpiece in the thermal processing and heat treatment process. The large bottom plate of the ring heating furnace is set at the bottom of the ring heating furnace, and it needs to work stably for a long time under the condition of bearing load in a high temperature environment. The commonly used large bottom plate of the annular heating furnace is made of ordinary heat-resistant steel casting process, which has many shrinkage cavities, non-compact structure, poor strength and stability in high temperature environment, unstable performance, variability, The working life is short and cannot meet the working needs of the annula...
