Overview
This series of bell-type hydrogen protection diamond saw blade sintering resistance furnace (Referred to electric furnace) is a sintering equipment that produced according to the variety of sintering furnace's advantages and disadvantages, in the diamond saw blade expert's guidance, improved after user many times trial experience. It was well-designed and manufactured and suit for variety of sintering equipment and the different specifications in diamond saw blade industry. It has a high yield, sintering speed, high output, low energy consumption, low cost and other characteristics. There are the following advantages.
The temperature of this series of electric furnace was separated for upper, middle and lower and controlled individually. Using a SCR PID self-tuning temperature control mode. The dual display smart table instrument ensure the district set the temperature uniform performance. The temperature difference is within 2℃
The heating element of the electric furnace is made of nickel-chromium alloy wire, has long service life and is easy to be repaired, and adopts the new type silk brick to ensure that the heating element does not come out at work.
The electric furnace with more than one seat, continuous rotation heating, to meet the requirements of large quantities of work, greatly improve efficiency.
The electric furnace with hydrogen protection, so that products can keep the color bright, no surface oxidation. On the first processing is not successful, the temperature does not meet the requirements of the product reheating, can still meet the sintering requirements of the saw blade. So the product's scrap rate is very low.
For the same product only need to set a processing temperature and time. When you have processed a batch of products, another batch of the same product into the electric furnace processing, do not need to re-set the temperature and time.

Introduction of structure
The series of electric furnace is consisted of the base, guide column, inner cover, furnace body and other components. The base is made of steel plate and steel welded, filled with high temperature casting material. The base heating part is used high temperature stainless steel. The workpiece can be very convenient and very flat on it. The base is welded with air intake and exhaust pipe (intake pipe is fine, trachea pipe is thick). Welding at the bottom of the furnace with a cover positioning device, guide column and guide column sets, it's easy to each inner cover, the furnace can accurately locate. The inner cover is made of heat-resistant steel. If the bottom is deformed or cracked after a prolonged use, it can be cut to repair. The rest of the parts can still be used to reduce production costs.
Furnace body is consisted by the furnace shell, lining, heating components and other components. The furnace shell is made of steel plate and profiled steel. The lining is made of lightweight refractory masonry. The insulation layer is made of lightweight insulation material. The top insulation part is compressed by high quality refractory fiber blanket which is both heat preservation and energy saving. The heating element is made of nickel-chromium alloy wire wound into a spiral shape, evenly distributed in the furnace around the silk brick. Using two plugs brick side by side way to fix the resistance wire to ensure that the furnace wire does not come out.
The furnace can be used with KKW series control cabinet. The use of SCR PID self-tuning temperature control, divided into three independent temperature control. Automatic or passive control temperature.
The hydrogen required by the electric furnace is provided by the user. User self-device of hydrogen cylinder placement and air supply control accessories. In the installation away from open flame and high temperature occasions should be considered to ensure safety.
Installation of electric furnace
1、Electric furnace was packed with furnace body, the base, the Inner cover, control cabinet, instrumentation, the accessories, and the installation instruction.
2、All the parts shall be checked whether there is damage or losing due to transportation before installation. All the parts shall be remove the dust and repair the defects that found firstly and then install it.
3、Install it according to the actual needs and driving position. Measure the height of the traffic is sufficient, and consider the laying of electricity, gas pipeline position.
4、When installing the base, check that the centerline is consistent with the centerline of the drive. Consider the level of work surface and floor of electric furnace.
5、Check the heating element part of the broken, crack, serious bending and out of the brick and other problems. At the same time, check the insulation of phase and phase, phase and ground to prevent short circuit and other abnormal phenomenon.
6、Check whether the contact terminals of the heating element, control cabinet, thermocouple and compensating lead are in good contact. Especially whether the thermocouple is fixed. Whether the wire and compensation wire are falling when moving, or pulled too tight. Note that the live part cannot be short-circuited.It should be connected to a reliable grounding wire (including the electric cabinet control cabinet) to ensure operator safety.
7、Each base will be connected to the hydrogen pipe, installed the valve. And check there's no leakage.
8、Check and running the electric furnace after installation.
PS:Our company can provide customized design according to user requirements.
