The annealing furnace is suitable for spheroidizing isothermal annealing of various bearing steels, tool steels or other industrial steels.
Description
The utility model belongs to metallic heat treating furnace, particularly is suitable for the annealing furnace of specialty products.
The existing nodularization isothermal annealing stove that is applicable to all kinds of bearing steels, tool steel or other industrial steel, be the electroheating type annealing furnace, because it is simple by electrically heated, the heat temperature raising section of this stove is slow to the rate of heating of workpiece, heat-up time is long, make the omnidistance annealing time of workpiece elongated, the working efficiency step-down of stove.Because heat-up time is long, and the oxidation of workpiece surface, decarbonization degree are increased the weight of, the globular carbide granularity increases, and the phase error of workpiece is big, thereby has influenced annealing quality, and workpiece annealing first-time qualification rate is reduced.
The purpose of this utility model is to overcoming above-mentioned defective, provides a kind of short to the workpiece heat temperature raising time, and the worker leads height, and energy consumption is low, the rapid isothermal spheroidizing annealing furnace that the workpiece annealing quality is high.
The technical solution of the utility model rapid isothermal spheroidizing annealing furnace is to be provided with in the furnace shell roller rod conveyer, electric heating device and the measurement and control of temperature element that chain drives, its special character is that nearly feed end one section is provided with the fuel Heating district in the furnace shell, is disposed at this fuel Heating district and is provided with oil burner.
Described furnace shell one end is provided with loading bay, and the other end is provided with discharge pedestal.
The workpiece processing district vertically is provided with heat preservation zone from feed end to the discharge end direction described fuel Heating district that continues in this annealing furnace furnace shell, and the heat preservation zone that continues is provided with fast cold-zone, and fast cold-zone is provided with air cooling equipment.
Both sides, workpiece processing district are provided with the body of wall of laying bricks in this annealing furnace furnace shell, and the body of wall inboard of laying bricks is provided with guardrail, and laying bricks is provided with thermal insulation layer between body of wall and furnace shell.
The utility model rapid isothermal spheroidizing annealing furnace is owing to be provided with the fuel Heating district and the corresponding oil burner that is equipped with, being used for the workpiece rapid heating heats up, this fast to the workpiece heating in the annealing furnace more than electrically heated speed with fuel oil, consuming time few, so compare with conventional electrically heated annealing furnace, this annealing furnace is fast to the workpiece rate of heating, the work efficiency height.On probation showing, to compare with bell-jar electric annealing furnace commonly used, this annealing furnace can shorten 10-12 hour to the omnidistance annealing time of workpiece; This annealing furnace can adopt the heating of " No. 0 " diesel combustion, the rapid heating characteristic and the hot working efficiency of this diesel oil have been made full use of, good thermal insulation property in conjunction with stove itself, normally add man-hour continuously, oil, the electric energy consumption total amount is quite low, with electrothermal oven ratio commonly used, this annealing furnace workpiece annealing cost can reduce 40%-50%.Because heat temperature raising speed is fast, workpiece shortens heat-up time, thereby has reduced oxidation, the decarbonization degree of workpiece surface, makes the globular carbide of workpiece surface become thin and fine and close, and annealing quality is improved.
