AI Technical Summary

Technical Problem

The existing graphite boat cannot fully adapt to the inner wall of the circular furnace, resulting in large gaps on the top, bottom and left and right edges of the inner wall of the furnace after installation, resulting in the atmosphere flow in the sintering furnace being out of control, affecting the uniform heating of the material.

Method used

By setting side joint plates on the left and right sides of the graphite boat plate, the side joint plates have an arc-angle structure, and an arc-angle structure similar to the side joint plates are arranged on the outer walls on both sides of the graphite boat plate, the whole graphite boat is more in line with the furnace wall of the furnace, reducing gaps and controlling atmosphere flow.

Benefits of technology

The fit between the graphite boat plate and the furnace wall is improved, the fluidity of the atmosphere inside the furnace is enhanced, and the heating effect of the material is improved.

Abstract

The utility model belongs to the technical field of vacuum sintering furnaces, and particularly relates to a boat pushing plate for improving atmosphere in a furnace and a furnace body assembly, which comprise a graphite boat and are characterized in that the graphite boat comprises a graphite boat plate and a graphite boat vessel movably abutted against the bottom of the graphite boat plate, the graphite boat plate is arranged in a T-shaped structure, and the graphite boat vessel is arranged in the graphite boat plate. Side connecting plates are arranged on the left side and the right side of the graphite boat plate, the side connecting plates are arranged in an arc angle structure, and a butt strap is arranged at the bottom of each side connecting plate, so that the graphite boat plate can be better attached to the furnace wall through the arrangement of the arc angle structures of the side connecting plates, and meanwhile, the outer walls of the two sides of the graphite boat are arranged in the arc angle structures similar to the arc angle structures of the side connecting plates; therefore, the whole graphite boat can be more easily attached to the furnace wall of the hearth, gaps at the joints of the graphite boat and the left side and the right side of the hearth are reduced, the atmosphere in the hearth can only flow along the upper end and the lower end of the graphite boat plate, and the heating effect on materials contained on the graphite boat plate is improved.
