1. Product Introduction
Carburizing agent, there are many kinds of raw materials, production processes are different. It has wood carbon, carbon coal, coke, and graphite type in which various categories and a lot of small types. High quality carburizing agent generally refers to after graphite carburant. Under the high temperature, the carbon atoms arranged in graphite morphology,so called for graphitization. graphitization can reduce the content of impurities in the carburant, increase carbon content and reduce sulfur content.It used for casting steel and iron. With high carbon and low sulfur, low water content and low cost characters.
2. Classification
At present, there are 3 kinds of commonly used carburetant:
First, graphite powder, which is a vacuum powder by graphite electrode processing.
Second after petroleum coke, which is used in some domestic steel plant to make of carburizing agent.
Third is the graphitized petroleum coke, which is also used as recarburizer in steel making.
3. Application
Induction furnace carburizing; cupola furnace carburizing; double process carburizing; furnace ladle with the current carburizing
4. Process
Take the Taixi Anthracite into the graphite furnace, in accordance with the power curve send to the furnace power, under the high temperature of 800 DEG --1350 DEG C,it occurs a series of physical and chemical reactions, and discharge the sulfur content, moisture, volatile, ash and other impurities, and then cooling, crushing, packaging and storage according to the size requirements of service.
The raw materials from the top into the tank feeding device during the calcination, in the process of moving from the top to down,it being located by tank fire on both sides of the heating. The heat in the combustion is generated by the fire wall directly to the raw materials. When the raw materials` temperature reached 350~600 degrees,the large number of volatiles released through volatilization. Then collected and sent to the burning fire lane. The volatile combustion is another source of heat pot calciner. Raw temperature after above1200 to 1300 DEG C`s incineration, it completes a series of physical and chemical changes, then from the bottom of the material tank into the water cooling, and finally discharged outside the furnace by the feeding device .
The carburizing agent after the calcination, then after cooling and into the roll crusher, sorting, crushing, in order the granularity reached: 0--1mm, 1--3mm, 3--5mm, 5--8mm, 8--10mm, 10--25mm, etc., and then packaging according to different needs of customers.
5. Transportation and Packing
Woven bag, lined with plastic film bags, each 25kg can also be packaged according to customer demand.
The product should be placed in a cool and dry place during storage, transport process, prevent and hard material mixed, to prevent carbon particles broken, affecting the quality of packaging to prevent breakage. To avoid leakage or mixed with debris, water, oil and fire.

1. Loosen the bolts that secure the IKO housing. Remove the IKO bearing from the shaft together with the IKO housing. Note the IKO housing at the end of the shaft. The IKO bearing block bolt at the other end of the shaft should be loosened; the two IKO bearings should be prevented from being damaged by each other. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2. First use the Allen key to loosen the locking screw on the IKO bearing misalignment sleeve; then use a small iron rod to puncture the counterbore on the top cover's painful sleeve; against the rotation direction of the shaft, loosen the partial pain sleeve.
Many people use improper device methods in the IKO bearing device; cause damage to the IKO bearing. So how to properly install the IKO bearing? I hope that we can more fully understand the installation and disassembly of IKO bearings:
IKO bearing ring for gap cooperation; it is recommended to apply a thin anti-corrosion agent on the cooperation surface; to prevent conflict corrosion between the cooperation surfaces. 390000 series outer spherical IKO bearing is IKO bearing inner ring and shaft through the painful sleeve Fixed; the hexagonal screw on the painful sleeve is used for fastening effect. During the repair; many operators will not disassemble this IKO bearing; therefore it is necessary to analyze the skill and attention of the disassembly and assembly of the 390000 series outer spherical IKO bearing. matter:
The correct device; very important for the use of IKO bearings. We hope that we can use the correct device approach in future applications.
When it is installed; it can be selected according to its type and scale; mechanical, heating or hydraulic means. The effect exerted on the IKO bearing when the device is applied; it must not be transferred from one IKO bearing ring to another IKO bearing ring through the rolling body; otherwise Damage to the raceway. But in any case; can not directly hit the IKO bearing ring, cage, roll or seal. Device 3. Install a partial pain set. First set the partial pain on the painful step of the IKO bearing inner sleeve; and tighten the direction of the hand by the direction of rotation. Then prick the small iron rod into or against the counterbore on the painful sleeve. 1. Use the hammer to strike the small iron rod in the direction of rotation of the shaft. Make the painful device firm; finally lock the hexagonal screw on the painful sleeve. 4. Do not tighten the bolts of the fixed IKO bearing seat; make the IKO bearing casing change in the IKO bearing housing. Then fasten the IKO bearing bolts. Also install the other end IKO bearing and seat on the same shaft; Change a few laps; let IKO bearings take the initiative to find the correct position.
5. Apply smooth oil to the IKO bearing seat and IKO bearing; install the IKO bearing into the IKO bearing housing. Then place the IKO bearing on the shaft with the IKO bearing. Push to the desired position to carry out the device.
6. Before the IKO bearing is imported to the shaft; the fixing pin of the IKO bearing casing must be unplugged; the outer surface of the journal is polished and cleaned together; and the oil is rust-proof and smooth at the journal (a slight adjustment of the IKO bearing on the shaft) ).
