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 industrial furnace masonry?
Masonry industrial furnaces refers to complete materials such as brick kilns in construction process.
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 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:How many kinds of industrial electric furnaces are there?
Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.
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:Brief introduction to repair of industrial furnace
Although the number of industrial furnaces in general machinery plants is not large, the number of large repairs per year accounts for 16%-20% of the total number of repairs for all equipment, and the large repair costs account for about 18%-25% of the total repair cost of all equipment.
Q:What are the advantages of a vacuum furnace?
Energy consumption is lower than salt bath furnace. Modern advanced vacuum industrial furnace heating chamber is made of high quality heat insulation material and wall, which can concentrate electric heating energy into heating chamber with remarkable energy saving effect.
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:How to use industrial furnace equipment?
If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
