Box furnace (muffle furnace) Precautions

Because box furnace (muffle furnace) products are high fever, so in daily use must pay attention to the safety of life and property of the State Security.
One would be automatic temperature controller flat on a smooth place'' not'' in order to avoid too close from EAF furnace heat affect electronic components'''' and then remove the short route to the furnace with the power cord into an electric furnace and then'' to the power cord connected to AC 220V'' and furnace controllers are effective electrical connection.
Two. Thermocouple with a wire connected to a temperature controller'' Note'' ± pole can not be wrong check again whether there is installed an error.
Three would be the thermostat to the desired temperature'' connected control box "type" of power'''' At this point turn the power switch into the red light green light to start work.
Four when the muffle furnace first time or long-term disabled again after use and must be oven dried.
Note:
Installation of all electrical distribution equipment and instrumentation through checks and adjustments'' and check the furnace and the voltage is normal'''' has good contact with the maximum temperature never exceeds the limit temperature series product configuration object'' to take the furnace must be cut off power to ensure safety'' furnace should be placed in a dry place to prevent moisture'' use'' leakage and cracking caused by heating refractories such as automatic temperature controller needs to swap places'' need'' to connect the console to avoid damage to the short route vibration meter.

Low-temperature box furnace

Introduction to the low-temperature box furnace
Uses: mainly used steel workpiece quenching, normalizing, annealing conventional heat treatment with special equipment.
Features:
1. Electric furnace loading capacity, high productivity, especially for small and medium-sized mechanical heat treatment heating, energy saving up to 20%, temperature uniformity, the DRO automatically furnace temperature control, high precision;
2. Electric furnace installed Imperial material, operating conditions;
3. The seal of the door and the furnace for self-sealing, without manual sealing
4. The electric furnace has interlock protection device to prevent misoperation due to failures and accidents;

The double furnace chamber fuel tank roaster

Double oven chamber fuel tank roaster uses:
Double oven chamber fuel tank roaster suitable for precision forging, high consumption of resources is one of the difficulties plagued precision forging industry, fuel roaster roasting touch shell pouring step is the forging of gas guzzlers, especially fuel unit price and raw materials The unit price spiraling resulting in the high casting cost, straightforward affect the precision forging the efficiency of enterprises.
The double furnace chamber fuel tank roaster structure:
Double oven chamber fuel tank roaster, user resistance produced on-site test fuel economy achieved remarkable results, functional winning the user what to order three. For the phase-out of the fuel tank have been used roaster. Facilities construction and the work theorem new fuel tank roaster by two furnace chamber. A furnace chamber when the cannon refining touch another furnace chamber housing using waste heat to preheat the guns furnace chamber, in order to fully take advantage of the thermal energy of the fuel occurs, to achieve the goal of parsimony fuel.
The two furnace chamber alternately be used as a gun refining, preheating, using the same fashion oven baked with single furnace chamber roaster, easy to operate. The double furnace chamber fuel tank roaster reference energy efficient burners, compressed oxygen fuel atomization, fuel atomization full fuel completely, gun refining performance. The double furnace chamber fuel tank roaster reference high-quality lightweight refractory bricks, and the wall of the furnace oil furnace casing during complement the high-quality refractory fiber insulation, furnace furnace insulation function.

Box-type furnaces in the course of operating personnel should be increased to prevent

In recent years, the adoption of electronic thermostat assembly box furnace, box-type furnaces and other products together for industry, agriculture, the implementation of room heating. Surface electrostatic spray adoption process, the surface chic, perseverance has become more durable reminding known.
On the control box in the industrial furnace when we should pay attention to several aspects:
1 at the beginning of use, manipulate staff must first check whether what box type high-temperature furnace iron and other residual items, if you find any, we should clean to avoid falling when the iron made ​​into a short time signs;
2 box-type furnaces at work, pay attention to the workpiece into the furnace can not exceed the carrying amount of the oven floor;
3 inserted into the muffle furnace of the workpiece and the furnace thermocouple should not collide;
4 changes should follow the requirements of the workpiece, timed heating and cooling;
5 In order to ensure that the workpiece can be useful in the furnace burning in the manipulation of the process we can not open the door;
6 it will have to work out fine, the temperature is too high in order to avoid burns others;
7 To schedule of a box-type furnace inspection.

Sealed box furnace into the furnace technology

1. When everything is ready to pass the inspection before working furnace heating, when the the muffle furnace temperature greater than 750oC, only through endothermic atmosphere, the furnace gas positive pressure, and then lit the fire curtain and front room row of net operating.
2. Until the furnace heated to 930oC, the curtain of fire lit, the part is available into the furnace.
3. Quenching lifting mechanism, is expected out baskets channel, is also quenched, pre-cooling, and drain fixture position of the lifting mechanism and process requirements, generally on the platform below the first material basket quenching oil cooling, the material on the above platforms baskets workpiece pushed into the carburizing furnace heating, close the inner door, the third basket pushed the above platform into the front room, along with the net emission of decontamination preheating, under the platform material basket oil the Lek best baked, the inner door is opened first two baskets, baked quenching, and three baskets into the box furnace carburizing, and so on ad infinitum.
4. If the workpiece quenching, the baked air cooling, the material basket should be placed on the platform, pre-cooling, until the next platform material basket furnace installed, let the platform material basket fell baked.
5. Fire curtain door must seal the inner door seal fire curtain shall ensure that the furnace positive pressure, oil and gas will not be admitted.
