With the development and promotion of medium frequency induction furnace technology, the demand in the field of metal hot processing is increasing; the medium frequency furnace uses the principle of electromagnetic induction during operation, which is more energy-saving and environmentally friendly than traditional coal-fired furnaces. In the later use of the medium frequency furnace, basic excerpt …

The following takes the medium frequency melting furnace as an example to explain the precautions that the application enterprises should pay attention to during use:(1) The medium frequency induction furnace should use a special rectifier transformer to increase the power supply voltage and limit the no-load operation of the transformer.(2) Standardize the installation, shorten the excerpt …

Cast iron rolls The carbon content of cast iron rolls is about 2.5%-3.5%. According to the main material, they can be divided into four categories: ordinary cast iron rolls, high nickel-chromium infinitely cold-hardened composite cast iron rolls, high chromium composite cast iron rolls and alloy ductile iron rolls. The common structures in cast iron rolls excerpt …
