Hydraulic Cylinder Hardening Annealing Induction Heat Treatment Repairing Machine

Company introduction
Zhengzhou Tuohong Machinery Equipment Co., Ltd is located in Zhengzhou, Henan, China. We are committed to induction heating machinery and induction solution . Main product: Induction heating machine, High frequency induction hardening machine. Induction forging machine, induction brazing machine. Medium frequency Induction furnace,induction melting furnace. Auto feeding machine, etc. supporting equipment, like heat exchanger, cooling tower, infrared thermometer,transformer,ladle furnace, etc. Our city has xinzheng international airport (CGO),high way, fast train station,transport is very convenient.

Our company has developed a metal tube inner and outer wall cladding technology by using the new environmental protection technology promoted by the state. It is the latest technology for anticorrosion and wear resistance of metal pipes at home and abroad. This technology is used in the inner hole of the cylinder of the coal mine fully mechanized mining support jack. The piston rod and the repair of the inner wall of the oil pipeline are the advantages of our company.

Cladding has the following advantages over electroless plating
1. The thickness of the cladding is very uniform, so that the cladding layer with a thickness of 1mm or more in the tube is stainless steel.
2. A uniform thickness of the cladding layer can be obtained on the workpiece of ferrous metal such as copper, iron or aluminum to make the metal pipe durable, corrosion resistant and wear resistant.
3. Strong bonding, no falling off, no layer
4. The cladding layer is dense, the void ratio is low, and the corrosion resistance is good.
5. The hardness of the cladding layer is high and can be greatly improved by heat treatment. Has good self-lubricating and wear resistance
6. No pollution, it is the new environmental protection technology promoted by the state.

Cylinder inner wall heat treatment 


Technical parameters of induction heat treatment repairing machine TZP-200
The technology successfully solves the technical problem that the inner cylinder of the jack jack cylinder and the outer diameter of the piston rod are not easily recovered.
1. Technical characteristics
The repaired cylinder and piston rod have high bonding strength, no pinholes, no pitting, long service life and superior corrosion resistance than the new cylinder. Cladding thickness up to 2mm
2. Maintenance scope
For the inner cylinder hole with a diameter of 100mm or more in the cylinder, the internal cylinder and the outer diameter of the piston rod are pulled, rusted, expanded, pitted, worn, etc. for effective dimensional recovery.

Advantages of hardening annealing induction heat treatment machine

1,  high frequency transistors my company adopted than high frequency power saving up to 40-60%, saving 60%, external support facilities to reduce investment by 75%. 
2, a unique cooling circulation system, ensure that the equipment 24 hours of continuous work.
3, small size, light weight, easy to move, no million-volt high-voltage danger, safe operation.
4, high reliability, easy to maintain and improve the over voltage, over current, overheating, lack of, water and other self-protection.
5, the use of large scale integrated circuit digital automatic control, with manual, automatic, semi-automatic and fixed time control.
6, automatic frequency tracking, stepless power adjustment, easy to use, 10 minutes to learn.

FAQ 
1. What's your MOQ?
For now, we have not yet strict policy about the quantity. Any quantity will be OK.
2. Can you send me similar video for my application?
Yes. We have many machine working onsite videos. Such as brazing, forging, hardening, shrink fitting, etc. 
Also according to your your work pieces, we can send you similar video for reference.Sometimes, we can send the same work piece heating video,then,you will see the whole heating or production process.
3. I am new , about this product
It doesn't matter. We have experienced sales and professional engineer , communicated and guide you. We will design and recommend you the suitable machine model (power and frequency, coils). Usually, you just need tell us your work pieces' specifications and heating requirements, or detailed applications.
4. Can you make special coils for my work piece?
Yes. Usually we provide 2 piece of coils, together with the machine.
5. Can we have extra induction coils ?
Yes. We can tailor-made extra coils, if you need. While you only need pay very low cost,factory price.
