Stepping type automatic overturning heating furnace

Abstract

The invention provides a stepping type automatic overturning heating furnace, which is provided with a furnace body, wherein a hearth is arranged at the upper part of the furnace body and the upper part of the hearth is provided with a combustion nozzle; fixed beams are horizontally arranged at the bottom of the hearth along the transverse direction; a movable beam is arranged between the fixed beams; one row of cantilever rollers are horizontally arranged at the left side of the hearth in the vertical direction; the cantilever rollers are located between the furnace wall of the furnace body and the left end faces of the fixed beams and the movable beam; a hoisting mechanism is arranged at the bottom of the furnace body; the hoisting mechanism is provided with a translation mechanism; the movable beam is fixedly arranged above the translation mechanism; heat-resisting cushion blocks I are arranged on the fixed beams; and the upper end face of each heat-resisting cushion block I is a V-shaped inclined plane. According to the stepping type automatic overturning heating furnace, the heat-resisting cushion blocks with the rolling inclined planes are adopted to be matched with a hydraulic stepping mechanism to realize automatic material overturning; and titanium and a titanium alloy circular blank are heated uniformly so as to guarantee the subsequent machining quality of the titanium and the titanium alloy circular blank.

Description

technical field [0001] The invention belongs to the technical field of cylindrical metal billet heating, and in particular relates to a step-by-step automatic turning heating furnace. Background technique [0002] The thermal conductivity of titanium and titanium alloys is only one-fifth of that of steel. If the billet does not rotate during the heating process, the temperature of the material surface contacting the bottom of the furnace will always be lower than the upper temperature of the material surface, and a "yin and yang surface" appears, and the billet is heated unevenly Will affect the product processing quality. In the existing technology, there is a walking beam heating furnace that uses heating on both sides of the upper and lower sides to eliminate the temperature difference between the upper and lower sides of the billet. However, since the billet does not rotate, the bottom temperature of the billet in contact with the walking beam is always the upper tempera...

Problems solved by technology

[0002] The thermal conductivity of titanium and titanium alloys is only one-fifth of that of steel. If the billet does not rotate during the heating process, the temperature of the material surface contacting the bottom of the furnace will always be lower than the upper temperature of the material surface, and a "yin and yang surface" appears, and the billet is heated unevenly Will affect product processing quality

In the existing technology, there is a walking beam heating furnace that uses heating on both sides of the upper and lower sides to eliminate the temperature difference between the upper and lower sides of the billet. However, since the billet does not rotate, the bottom temperature of the billet in contact with the walking beam is always the upper temperature, which cannot completely eliminate the temperature difference between the upper and lower sides of the billet. Temperature difference, not suitable for heating titanium and titanium alloy blanks
