At 11:58 on April 27th, the VIM 4T furnace of Shanghai Xinyan Industrial Equipment Co., Ltd successfully completed the test.The project started in mid-August last year, and the installation began in mid-January this year.In order to ensure the early use of customers, engineers and the installation team worked overtime during the Spring Festival, went all out to complete the installation of the entire equipment in the shortest time.
With the close cooperation of colleagues in various professions, the whole cold commissioning process was shortened to 19 days, which gained the customer time.After multiple tests, the power supply system, vacuum system and so on have passed all the tests smoothly, and all the indicators have reached or exceeded the design level.This result also marks the official commissioning of the Vim 4T furnace.
Vim 4T furnace has many advantages in design: a standard furnace model Vim-400, designed to connect 3, 4 tons of furnace body, this Vim furnace is equipped with a 4 tons of furnace body;Multiple chamber design, including melting Chamber, charing Chamber, Mold Chamber and Launder Chamber, etc. Isolation valves are set between each chamber to achieve flexibility of operation. The whole production stage, from the loading of raw materials to the casting process, will be carried out under vacuum or controlled air pressure, continuous operation of production to improve production efficiency.Longitudinally installed flow slots achieve better final product cleanliness and yield;The overall structure is firm and reliable, the main steel structure is all water-cooled, and the neat and reasonable equipment layout is helpful for the process implementation and management of customers on site, which can greatly reduce the total height and the area of the equipment to the maximum, and the machine equipment maintenance is convenient;
The newly developed high efficiency IGBT power supply, electromagnetic stirring, inert gas washing, automatic frequency control and automatic process control system are all optional equipment features, which are defined by modern configuration at present.The pre-heating of the cauldrons can be carried out under a vacuum, so as to obtain less gas output rate and higher vacuum degree;Advanced safety systems include emergency blowout valves and emergency argon blowing devices;The modular design concept can be combined with different casting options;Remote operation can be realized through video.
The newly developed VIM 4T furnace represents a new generation of smelting furnace for continuous production of ultrapure metals and alloys based on traditional VIM technology. It is safe, efficient, environmentally friendly, economical and convenient!
