Combination type resistance furnace is our company rely on the research institute has just been born of the new furnace. It is a collection of a variety of modern scientific and technological achievements in one. In the structure broke through the shackles of traditional ideas and overcome the old furnace after the completion of the shape, the size is fixed, unable to relocate the ills, furnace body on an innovation and breakthrough. Has nearly a hundred pieces of product of Daqing Petroleum Administration Bureau, Shengli Oilfield, Zhongyuan ethylene, China offshore oil platform manufacturing company, Harbin Boiler Factory and other dozens of users in the success of heat treatment services, user response.
(a) the structure of simple investment province, the rapid cycle of building a furnace is short
This is not the assembly type resistance furnace cover. It has no large kiln trolley and a furnace door, thus eliminating the need for operation of the trolley driving system, door and rise, drop and sealing and pressing mechanism, there is no need for furnace construction plant, equipped with cranes, eliminating the many facilities, built furnace cycle can be shortened by 80 percent.
(two) easy to assemble and easy to move, easy maintenance operation
The stove to the earth for the bottom, the ground covered with aluminium silicate refractory fibre needled blanket or superfine glass quilts do heat preservation, refractory and heat insulation layer, the furnace furnace wall and furnace cover all adopt the special connection elements and I-steel furnace body plate (see Figure 3) splicing together constitute the. Disassembly, relocation is easy, operation, maintenance is also very convenient, workers without long-term training, a little guidance can be quickly mastered.
(three) volume and power are variable, and use a wide range of flexible use
Both the furnace body and the electric heating body of the furnace are composed of an independent element, a furnace body plate and a frame heater. With these components can be built into different shape, volume, and power of the resistance furnace to meet the various petrochemical equipment, pressure container and metal components heat treatment heating needs, not only is very flexible and convenient, and the application is more extensive, we have built a small stove volume 2m3, large volume of more than 560m3. And it can also be smaller or bigger.
(four) computer control temperature difference is small, the realization process of high quality
The stove is according to required size power equipped with one or more than one computer temperature controller, each temperature control instrument which has 12 circuit power supply, 12 thermocouple temperature control power using PID regulation, temperature control accuracy of + - 1 DEG C, the whole furnace in heat preservation phase temperature can be controlled to plus or minus 5 DEG C. Figure 4 and figure 5 is the export products - 300 and 500 type storage tank for CO2 welding after annealing by the curves of the annealing process recording instrument recorded more than 400 degrees C, in Figure 6, is polyester engineering, Tianjin petrochemical joint material for heat exchanger shell welding after annealing by recording instrument of more than 300 DEG annealing process of record curve.
(five) assembled resistance furnace
(1) (right) small assembly of CO2 tank type resistance furnace annealing structures.
Furnace size: length 5.4m x width 2.8m x high 1.5m
(2) (left) regenerator chamber set annealing after welding assembly resistance furnace building
Furnace size: length 5.6m x width 5.4m x high 3.1m
(3) the assembly type resistance furnace for the post weld annealing of the cone transition section of the xylene tower.
Furnace size: length 7.5m x width 7.5m x high 4.5m
(4) the assembly type resistance furnace of the heat exchanger shell (see left and below) after annealing. In change in the middle of the heat exchanger shell has a lug type bearing, in order to reduce the volume of the stove, furnace shape better and for heat exchanger shell which is adapted to the shape, so the furnace is built high in the middle and lower in both sides, its shape is convex shape.
Furnace size: length 4.35m x 13.7m x height: middle 4.5m, two 3.6m
(5) a type of electric resistance furnace for the drying of the lining of the tank and the lifting pipe (see figure below).
Furnace size: length 16.75m x width 4.35m x high 2.54M
(6) (see below) of FCC regenerator shell segment heat treatment to build assembly resistance furnace.
Furnace size: length 10.37m x width 10.17m x high 5.4m
