Description

Technical Field

[0001] The utility model relates to the technical field of solution treatment furnaces, in particular to a heating furnace connector with stable connection. Background Art

[0002] Solution treatment is a heat treatment process in which the material or workpiece is first heated to an appropriate temperature and held for a sufficient time to fully dissolve the soluble phase. The material is then rapidly cooled to room temperature to produce a supersaturated solid solution. In existing solution treatment furnaces, two adjacent heating furnaces are connected by flanges. However, during operation, the furnaces expand and deform at high temperatures, and the two adjacent furnaces cannot maintain the same expansion direction. This can cause the flanges to misalign and break, leading to the escape of hot air from the furnaces. Utility Model Content

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A heating furnace connector with a stable connection includes a sealing ring, a flange and a bellows. The flange is fixed to both ends of the bellows. The flange is installed at the feed port or discharge port of the heating furnace through the sealing ring. The bellows includes an arc portion and a connecting portion. The two arc portions are connected through the connecting portion.

[0006] As a preferred technical solution, the flange includes a mounting portion, a connecting portion and a positioning portion, the connecting portion is fixed on the mounting portion, the mounting portion is fixed to the heating furnace, and the end of the arc portion is fixed to the connecting portion.

[0007] As a preferred technical solution, the mounting portion is provided with long fixed holes, and the long fixed holes are arranged in order along the edge of the mounting portion.

[0008] As a preferred technical solution, the flange and the bellows are in a square frame shape.

[0009] As a preferred technical solution, the flange further includes a positioning portion, the positioning portion is fixed on the connecting portion, and the positioning portion is fixed to the base.

[0010] As a preferred technical solution, the positioning portion includes a positioning rod and a positioning seat, one end of the positioning rod is fixed on the connecting portion, and the other end is fixed to the positioning seat.

[0011] As a preferred technical solution, the positioning seat is provided with positioning holes, and the positioning holes are arranged in order on the positioning seat.

[0012] The beneficial effects of the present invention are as follows: the above-mentioned firmly connected heating furnace connector is provided with a bellows, the arc portion in the bellows can be stretched to match the feed port or discharge port of the heating furnace, and the bellows are made of 310S stainless steel. 310S stainless steel is an austenitic chromium-nickel stainless steel with excellent oxidation resistance, corrosion resistance, and high temperature resistance. Due to the high percentage of chromium and nickel, it has high creep strength and can continue to operate at high temperatures. It has good high temperature resistance. After the two adjacent heating furnaces are deformed under high temperature conditions, the bellows can be deformed as the flange installed on the heating furnace moves, avoiding breakage caused by high-temperature deformation of the heating furnace when the flange is directly installed, thereby avoiding leakage of hot gas.
