Q: What is the difference between industrial furnaces and boilers?: Hot water or steam generated in the boiler can directly provide necessary energy for industrial production and people's life, but also by the steam power device is converted to mechanical energy, or through the generator converts mechanical energy into electrical energy. Hot water boilers are called hot water boilers. They are mainly used in daily life, and are also used in industrial production. Steam generating boilers are called steam boilers, often referred to as boilers. They are used in thermal power stations, ships, locomotives and industrial and mining enterprises.

Q: Should the industrial furnace shell cool down?: Normally, the furnace shell temperature of an industrial furnace is below 50 degrees, so there is no need to cool down.

Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.

Q: What are the companies in the world that are currently engaged in metallurgical furnaces?: There are many kinds of furnaces in metallurgical industry,colored and black,smelting and heat treatment are also included.

Q: What are the combustion equipments used in industrial boilers?: The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.

Q: What is industrial furnace masonry?: Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.

Q: Why does the burner of industrial furnace burn occasionally?: The flameout protection system is made up of burner controller, electromagnetic valve and flame detector, and the flame detection mode is mainly based on the two forms of ultraviolet detection and electrode detection. By utilizing the electric conductivity of the flame, the circuit path of the combustion process generates a weak current, and when the signal amplifier is amplified, the flame is induced to exist, and the small power burner adopts the detection mode more, and is economical and practical.

Q: What is the difference between industrial furnace masonry and ordinary masonry?: Of course, the difference is like the difference between a hog cap and a 100 story building. See the industrial furnace manual.

Q: How to use industrial furnace equipment?: When the furnace is used, the lifting mechanism of the furnace door must be in good condition, and the wire breakage of the steel wire is not allowed to exceed the designated value. The weight should be properly allocated, and the drive department shall be provided with a protective cover.

Q: What is an industrial furnace pit?: Later, a chamber kiln with a semi closed or fully enclosed kiln made of refractory bricks can be used as fuel for coal, gas or oil, and electricity can be used as heat source. The workpiece will be heated in the kiln hearth.
