Abstract
The invention discloses tempering equipment of a vacuum gas quenching furnace. The tempering equipment comprises a furnace body, a liner and a furnace cover; the furnace body is composed of a furnace base, a furnace shell and a furnace lining; the furnace shell is fixed on the furnace base and is internally provided with a hearth enclosed by the furnace lining; the liner is arranged in the hearth; a bracket is fixed at the periphery of the hearth; an electric heating element is fixed on the bracket; and the furnace cover is fixedly provided with a fan device, a hanging frame, a manual valve, a protective gas filling pipe and a vacuumizing pipe. The tempering equipment is characterized in that the vacuumizing pipe is provided with an electromagnetic valve. The tempering equipment is simple in structure, reasonable in design, good in uniformity of the whole furnace temperature and long in service life. According to the tempering equipment, an oxide scale is not generated on an annealing workpiece, cooling can be rapidly carried out after heating is finished, and the production efficiency is greatly improved.
Description
Technical field
The present invention relates to the tempering equipment of a kind of boiler plant, especially vacuum tempering furnace.
Technical background
Current vacuum tempering furnace usually uses internal heat type heating under vacuum conditions, and high voltage can produce electric discharge to beat arcing phenomenon during due to heating in vacuum, therefore must reduce voltage using transformer.The transformer price of 150KW, 70V or so is expensive at 40,000 yuan or so.And in vacuum state, heating element heater and cooling material requirement are higher, and cost is also high, so current vacuum tempering furnace is expensive.
The content of the invention
For problem above, it is an object of the invention to provide a kind of tempering equipment of vacuum air-quenching furnace, it is to close fire door after workpiece loads in stove to be vacuumized by vacuum pump set, the outer wall that vacuum reaches after requirement to Muffle pot is heated, and heat radiation is carried out so as to be heated to product by the tank skin of Muffle pot.Strong air-cooler is opened when soaking time reaches requirement to carry out quick cooling to reach efficient purpose.
The technical scheme is that be accomplished by the following way：A kind of tempering equipment of vacuum air-quenching furnace, including body of heater, inner bag and bell, the body of heater includes furnace base, furnace shell and furnace lining, the furnace shell is fixed on furnace base, there is the burner hearth that furnace lining is surrounded in the furnace shell, inner bag is located in burner hearth, and described burner hearth surrounding is fixed with support, and electrical heating elements are fixed on support；Blower fan apparatus, suspension bracket are fixed with the bell, hand-operated valve, protective gas pipe, vacuum-pumping tube is filled, it is characterised in that：Described vacuum-pumping tube is provided with magnetic valve.
Water conservation system is connected with vacuum-pumping tube on described bell, opening hand-operated valve carries out high-temperature vacuum pumping, the vavuum pump being connected with vacuum-pumping tube by water conservation system protection.
The screw lift structure installed on the body of heater and bell, for opening and closing bell and body of heater, is provided with sealing ring between bell and inner bag.
The present invention, simple structure, reasonable in design, whole stove temperature uniformity is good, and annealing workpiece non-scale is produced, and can quickly be cooled down after the completion of heating, greatly improves production efficiency, long service life.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Known by Fig. 1, a kind of tempering equipment of vacuum air-quenching furnace, is made up of body of heater 1, inner bag 2 and bell 3, and the body of heater 1 includes furnace base 4, furnace shell 5 and furnace lining 6, the furnace shell 5 is fixed on furnace base 4, there is the burner hearth that furnace lining 6 is surrounded in the furnace shell 5, inner bag 2 is located in burner hearth, the burner hearth bottom fixes refractory brick, drum-shaped stainless steel inner container 2 is fixed with refractory brick, inner bag 2 is opening up, and high-strength refractory brick has enough intensity to bear pressure, there is good resistance to elevated temperatures again.Blower fan apparatus 7 are installed with the bell 3, suspension bracket 8, hand-operated valve 9, fill protective gas pipe 11, vacuum-pumping tube 12, the screw lift structure 13 installed on the body of heater 1 and bell 3, for opening and closing bell 3 and body of heater 1, sealing ring is provided between bell 3 and inner bag 2, by the screw lift structure 13 installed on body of heater 1 and bell 3, lifting, open and close bell 3, bell 3 can be fixed and covered on burner hearth and inner bag 2, cover tightly burner hearth opening, with reference to being provided with sealing ring 17 between bell 3 and inner bag 2, sealing inner container 2 is open, ensuring that inner bag 2 is vacuumized is carried out without anaerobic annealing；Bell 3 can be opened after the completion of workpiece annealing, take out workpiece.Due to being connected with water conservation system 14 on the vacuum-pumping tube 12 on bell 3, opening hand-operated valve 9 carries out high-temperature vacuum pumping, and the vavuum pump being connected with vacuum-pumping tube 12 is protected by water conservation system 14.Burner hearth surrounding is fixed with support 15, and electrical heating elements 16 are fixed on support 15；Fill protective gas pipe 11 and be provided with magnetic valve 10, pressure gauge, flowmeter and be filled with protective gas for control.
