Dispersion rod of tilting drum type resistance rotary furnace for discharged quenching material

Abstract

The invention relates to a dispersion rod of a tilting drum type resistance rotary furnace for a discharged quenching material and a use method thereof. A dispersion rod for a discharged material is arranged in the middle of an anti-wind / cold device of a tilting drum type resistance rotary furnace. The dispersion rod for a discharged material is a flat metal rod having certain elasticity. The length of the flat metal rod is 1 / 4-1 / 3 of that of a lengthening pipe. The upper end of the flat metal rod is fastened at the upper end opening of the lengthening pipe by a bolt and a screw cap through a metal rod mounting hole. The middle of the flat metal rod is inclined down towards the middle of the lengthening pipe by a small angle. The lower end of the flat metal rod is tilted up towards the middle of the lengthening pipe to form a small metal rod hem, and the small metal rod hem is positioned in the circle center position of the lengthening pipe. Quenching parts drop along a branch pipe and the lengthening pipe, and scatter all around due to block of the flat metal rod, especially the small metal rod hem when the flat metal rod, especially the small metal rod hem is crashed. The invention ensures that a quenching material can dispersedly fall into a quenching bath when the quenching material falls down through a sleeve and the lengthening pipe, so that the temperature of the quenching liquid in every position in the quenching bath are basically the same. Thus, each quenching material can be evenly quenched, and the strength and rigidity of each quenching material can meet the requirements for high standard and high quality.

Description

technical field [0001] The invention relates to a discharge dispersing rod for quenched material in a tilting drum type electric resistance rotary furnace. Background technique [0002] The company applied for a utility model patent on September 5, 2005, its name is: outlet pipe windproof and coldproof device, the patent number is: 200520075415.1. This patent is that a wind-proof and cold-proof device is installed on the outlet pipe of the tilting drum type resistance rotary kiln. The main components of the windproof and coldproof device include two parts: a casing sleeve and an extension pipe set on the outlet pipe of the resistance rotary furnace. When the quenching material in the furnace is discharged, the quenching material does not contact the cold air outside the tube, so that the heat loss of the quenching material is small, and the quenching material directly falls into the quenching liquid in the quenching pool. In this way, the quenched material basically meets ...

AI Technical Summary

Problems solved by technology

The main disadvantage is that when the quenching material falls through the casing and the extension tube, it falls in clusters, and many high-temperature quenching materials fall into the same place in the quenching pool in a cluster, which increases the temperature of the quenching liquid in this place, and the increase in the temperature of the quenching liquid affects the quenching effect. The strength and hardness of the quenched material cannot meet the high standard and high quality requirements
