Description

TECHNICAL FIELD

[0001] The utility model relates to the field of heat treatment equipment, concretely relates to a vertical titanium alloy phase transition point heat treatment furnace feeding port automatic opening and closing device. BACKGROUND

[0002] The titanium alloy phase transition point is the temperature point when the internal organizational structure of titanium alloy changes from one crystal structure to another crystal structure during the heating process. Understanding and mastering the phase transition point of titanium alloy is of great significance for the subsequent study of the mechanical properties and processing performance of the material.

[0003] The vertical titanium alloy phase transition point heat treatment furnace, as a key equipment for titanium alloy phase transition point heat treatment, must ensure good sealing, no temperature running phenomenon and stable and reliable operation during operation.

[0004] Most enterprises in the industry currently use vertical titanium alloy phase transition point heat treatment furnaces for phase transition point heat treatment operations. The vertical titanium alloy phase transition point heat treatment furnace has a split-type atmospheric heat treatment furnace structure. It is composed of a heating system, a tubular furnace body, a control system, a cooling water tank, an insulation layer, a support frame and a discharge port, a feeding port and other parts,

[0005] The conventional vertical titanium alloy phase transition point heat treatment furnace feeding port basically uses manual laying of multiple layers of fiber cotton to block or open and close it. The maximum use temperature of the vertical titanium alloy phase transition point heat treatment furnace is 1050 DEG C. During operation, due to the chimney effect, heat will move upward as a whole, and the actual temperature of the feeding port is already higher than 1050 DEG C. The opening and closing mechanism of the feeding port will be deformed due to high temperature, causing the opening and closing mechanism to fail to open or close. In order to ensure stable and reliable operation of the equipment, manual laying of multiple layers of fiber cotton is used to block it.

[0006] Since the feeding port uses manual laying of multiple layers of fiber cotton: 1. There are certain gaps between the fiber cotton and the fiber cotton, and the fiber cotton cannot be tightly attached to the furnace port, resulting in poor sealing of the feeding port; 2. The feeding port needs to be manually laid with multiple layers of fiber cotton every time the furnace is loaded, and the laying quality is uncontrollable, with many human factors, so the equipment cannot be stably and reliably operated; 3. Manual laying of multiple layers of fiber cotton has low production efficiency. INVENTION CONTENTS
