Q:What's the role of anchor bricks in industrial furnaces?
The wall of an industrial furnace or flue is mainly composed of an inner lining layer, a heat insulating layer and an outer wall layer. The lining is a refractory brick, and the outer wall is an ordinary sintered brick.
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.
Q:Should the industrial furnace shell cool down?
If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.
Q:What are the advantages of a vacuum furnace?
The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating temperature of the thermocouple and the temperature of the furnace reach 1.5 C. But there is a large temperature difference in a large number of workpieces in different parts of the furnace. If the forced circulation of the rarefied gas is adopted, the temperature range of the temperature range of + 5 DEG C can still be controlled.
Q:Why does the burner of industrial furnace burn occasionally?
The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.
Q:What are the companies in the world that are currently engaged in metallurgical furnaces?
Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.
Q:Brief introduction to repair of industrial furnace
Compared with other equipment, industrial furnace repair has many characteristics: more repair times, more maintenance costs, more non-standard equipment and unsafe factors.
Q:Selection of heat preservation material for industrial furnace
In the neutral and oxidizing atmosphere, the tensile strength, toughness and fiber structure can be maintained for long term use. The temperature is 950-1400 centigrade. Excellent chemical stability; excellent thermal stability; excellent tensile strength; low thermal conductivity; low thermal capacity; excellent sound absorption and noise reduction performance.
Q:How many kinds of industrial electric furnaces are there?
This series of electric furnace is made of super light refractory fiber. The electric stove and the temperature control cabinet matching use, the controller may automatically or the manual control electric stove temperature, may press the user request to provide the computer table or the computer control, does the multielement temperature measurement, guarantees the product quality. This series of electric furnaces are periodical operation type electric furnaces.
Q:What is the difference in structure between industrial furnace and boiler?
Industrial furnace: main heating, steel and other metal materials, or ore and other materials. An industrial furnace of higher temperature, such as forging or heat treatment. Therefore, the energy consumption is large, and the insulation layer is designed to be thicker, and the structure is designed for the final purpose of the production purpose, the product process and the production efficiency.
