Industrial furnace repairs

Industrial furnace repair machinery thermal processing plants mostly in the 650 ℃ -1700 ℃ of temperature, therefore, bear masonry industrial furnaces and furnace heat ablation sudden change of temperature effect.
Of furnace gas and molten slag chemical attack and a variety of materials, high-temperature air and the molten metal impact wear, a combination of factors which accelerate the industrial furnace damage. Therefore, compared with the general cold equipment, industrial furnace technical condition prone to change, life is short, repair more times.
In general machinery plant, the number of industrial furnaces, while small, accounting for the total number of devices 5% -8%, but the annual overhaul Number of units Number of units accounted for all the equipment overhaul 16% -20%.
As we all know, cast iron with a cupola furnace will be carried out for each open one day a small repair; forging furnace, then at least once a year to overhaul.
Industrial furnace repair so many times, fast changes in working conditions at the plant in addition to the individual foundry equipment (such as molding machine, shot blasting machine, etc.), the fear in the number of all types of equipment to be "among the best."

Chamber furnace Products

Chamber furnace with a cube or rectangular furnace industrial furnace, also known as box-type furnace. Chamber furnace compartment flame furnace chamber furnace two categories, chamber furnace to strictly control the temperature. Chamber furnace combustion devices or electric components are mounted on the side walls or the bottom of the furnace, heat radiation, convection, and conduction heat transfer of the workpiece. The workpiece is heated to load and remove from the oven door. Furnace chamber structure is relatively simple, for heating of the workpiece in a single piece, small quantities, the workpiece by weight is generally not more than 3 tons, the the hearth area not greater than 10 square meters, the thermal efficiency is low.
Chamber furnace classified:
Chamber furnace uses can be divided into three kinds. The ① chamber furnace: for metal forging and thousands of welding heating furnace working temperature of 1000 to 1300 ° C. Gas and combustion air in the mouth after the first introduction of the burner mixing, then ejected combustion. Combustion gases in the furnace after the heating of the workpiece into the flue, and finally by the chimney into the atmosphere. Stove burner, furnace, metal hob, door, flue and adjust the flue of the furnace pressure gate. ②-chamber-type heat treatment furnace: normalizing, annealing and quenching, the furnace temperature of 800 to 1100 ° C, heating for tempering and aging, the furnace temperature 150 to 700 ° C is used to eliminate stress in the metal forging and heat treatment heating as . (3) Room type roaster: Investment Casting Shell roasting and enamel roasting furnace temperature of 850 to 1200 ° C.
Chamber furnace features:
Chamber furnace with sealed metal furnace shell, the heating element is mounted on the inner surface of the both sides of the furnace, the furnace bottom, and front and rear door. Tightness of the furnace, and more uniform heating, and the furnace temperature can be precisely controlled.

The structure of industrial furnaces

Industrial furnace heating the material to physical and chemical changes in industrial heating equipment. Furnace and kiln and distinguishable, but a slightly different meaning. In the machinery industry, generally used to complete workpiece or material thermal heating, melting and heat treatment process used thermal equipment called a furnace, and for silicate industrial heating equipment called a kiln. The industrial furnaces often referred to as industrial furnaces.
With the needs of the different production processes, the structure of industrial furnaces in many forms, but in general, shall meet the following requirements:
1) heating speed, high yield per unit area.
2) furnace temperature, the atmosphere is easy to control the product quality is good.
3) in the low energy consumption, high thermal efficiency.
4) The structure is simple, low cost, long life, easy maintenance.
5) operation is simple, a higher degree of mechanization and automation, less environmental pollution, good working conditions.

Advantages of vacuum heat treatment furnace

The vacuum treatment furnace is a device of the workpiece to a heat treatment under vacuum conditions, the vacuum processing and compared to other heat treatment method having the following unique advantages:
Purification action: make a metal surface oxide decomposition, thereby obtaining a bright, clean surface.
2, vacuum protective effect: metal can avoid the adverse effects of oxidation, decarburization, carbon keep the chemical composition and brightness of the original workpiece surface.
Outgassing: original dissolution of the workpiece may be removed in vacuo, the absorption of gas, so that the metal product performance has improved significantly.
4, the degreasing effect: heating in a vacuum, self-volatile cooling agent, a lubricant, such as grease to the metal parts used in the machining and stamping molding process, and is pumped in vacuo, and will not react with the surface of the part at a high temperature. It can be obtained no oxidation, no corrosion very smooth surface.
5, save energy: vacuum heat treatment furnace heat storage and heat loss, high thermal efficiency.
6, the heat treatment of the workpiece deformation is small, easy to crack, product qualification rate, long life; vacuum heat treatment can easily be in strict accordance with technical requirements to control the temperature change, so as to obtain the desired microstructure, reducing the deformation.
7, after the vacuum heat treatment product can be directly used for plating or as a final product, eliminating the step of cleaning, surface machining and other auxiliary greatly reduce production costs.
8, environmental pollution, high degree of automation, simple operation.
Vacuum heat treatment furnace features:
Quenching, tempering, annealing, brazing, sintering, etc. a variety of purposes;
2 fully automated process control, stable operation, human-machine interface (optional);
3 powerful cooling capacity the quench a wider range of applications;
Uniform heating, cooling uniformity, small deformation of the workpiece;
Energy conservation, and pollution;
6 kinds of protection function, make the operation safer;
Cooling Fan Frequency (optional), the cooling method is more flexible.
Vacuum heat treatment furnace uses:
Vacuum heat treatment furnace is widely used in alloy steel, tool steel, high speed steel, tool steel, bearing steel, spring steel, stainless steel, heat-resistant alloys, a variety of magnetic materials, non-ferrous metals heat treatment.
