Forge piece oxide skin removing device

Abstract

The invention discloses a forge piece oxide skin removing device. The forge piece oxide skin removing device comprises a hollow mounting frame, disc steel brushes, nozzles, fixed steel brushes, an air pipe, a fan and a fan shell are arranged on the bottom face of the mounting frame, wherein the nozzles and the fixed steel brushes communicate with the interior of the mounting frame, the air pipe conveys air into the hollow mounting frame, and the fan and the fan shell are arranged inside the mounting frame and driven by air flow to rotate; the multiple fixed steel brushes are arranged on the middle line of the lower surface of the mounting frame at equal intervals front and back, the fixed steel brushes and the mounting frame are integrally formed, small holes are formed in the middle positions of the bottoms of the fixed steel brushes, and the nozzles are symmetrically arranged on the two sides of the fixed steel brushes; and the disc steel brushes are arranged on the lower surface of the mounting frame in a bilateral symmetry mode along the middle line of the lower surface of the mounting frame and located on the two sides of the fixed steel brushes and the nozzles, the fan is mounted in a cavity of the mounting frame through a bearing, the fan shell is buckled on the fan, and a center rotating shaft of each disc steel brush is mounted on the bearing and rotates along with the fan. The forge piece oxide skin removing device is high in dephosphorizing efficiency, light in weight and resistant to high temperature.

Description

technical field [0001] The invention relates to the technical field of iron and steel metallurgy, in particular to a device for removing scale from forgings. Background technique [0002] After the forging is heated to a certain temperature, a certain thickness of oxide skin will be formed on its surface. The inner layer is thicker ferrous oxide, and the outer layer is thinner ferric oxide. From ferrous oxide to increasing the thickness of ferric oxide, during forging at this time, the oxide skin will be pressed into the surface of the forging, which will affect the surface quality of the forging, and will also accelerate the wear of the forging die and die, reducing the service life. [0003] At present, the industry generally uses the mechanical impact of high-pressure water to remove iron scale (high-pressure water phosphorus removal). This method consumes a lot of water, and the generation of water vapor will damage the surrounding equipment. In addition, the equipment u...

Problems solved by technology

[0002] After the forging is heated to a certain temperature, a certain thickness of oxide skin will be formed on its surface. The inner layer is thicker ferrous oxide, and the outer layer is thinner ferric oxide. From ferrous oxide to the direction of increasing the thickness of ferric oxide, at this time forging, the scale will be pressed into the surface of the forging, which will affect the surface quality of the forging, and will also accelerate the wear of the forging die and die, reducing the service life

[0003] At present, the industry generally uses the mechanical impact of high-pressure water to remove iron scale (high-pressure water phosphorus removal). This method consumes a lot of water, and the generation of water vapor will damage the surrounding equipment. In addition, the equipment used in this method is not only The weight is heavy, it is very inconvenient to carry manually and the descaling effect is easily affected by the water flow, water outlet angle, etc.
