The damage of heating furnace is generally mainly caused by coking, which is formed by the joint action of many factors. Coking is a phenomenon in which the oil in the furnace tube is thermally cracked when the temperature exceeds a certain limit, becomes free carbon, and accumulates on the furnace tube. The damage process is: coking begins in the tube, which increases the temperature of the tube wall, thereby intensifying the oxidation of the surface and the corrosion of the furnace tube. Oxidation reduces the thickness of the pipe wall, and the thinned part is first bulged out under the dual action of internal pressure and heat. After the furnace tube is bulged, the gap between the inner wall of the tube and the coke layer increases, which gradually increases the temperature of other parts of the furnace tube, further oxidizes and thins, and finally leads to the rupture of the furnace tube.
A chain is a common transmission device. The working principle of the chain is to reduce the friction between the chain and the sprocket through the double curved chain, reduce the energy loss in the process of power transmission, and thus obtain higher transmission efficiency. The application of chain drive is mainly concentrated in some occasions with high power and slow running speed, which makes chain drive have more obvious advantages.
A gold melting furnace is an essential tool for anyone who works with gold, whether you are a jeweler, hobbyist or metal refiner. In this blog post, we will give you some tips on how to choose the right gold melting furnace for your needs, taking into account factors such as capacity, fuel source and budget.
Speedy heating, high efficiency, low carbon oxidation off, saving the cost of materials and forging die. Due to the principle of electromagnetic induction heating, the heat is generated in the workpiece itself.Ordinary workers can proceed on the continuously forging task after ten minutes operation of induction heating furnace.
