Zhejiang University orders non-standard high-temperature crucible furnace

Zhejiang University is a prestigious institution of higher education with a long history, located in Hangzhou, a famous historical and cultural city and scenic tourist destination in China. The predecessor of Zhejiang University, Qiushi Academy, was founded in 1897 as one of the early modern higher education institutions established by Chinese people themselves. In 1928, it was named National Zhejiang University. During the War of Resistance Against Japan, Zhejiang University relocated to the west and operated for seven years in Zunyi, Meitan, and other places in Guizhou. In the autumn of 1946, it returned to Hangzhou. In 1952, when colleges and departments were adjusted, some departments of Zhejiang University were transferred to sister universities and the Chinese Academy of Sciences. In 1998, four universities with the same roots and origins merged to form the new Zhejiang University, embarking on a new journey to create a world university. I personally contacted Zhejiang University and visited 18 times for guidance, giving a series of important instructions on the school's reform and development, and outlining a grand blueprint for building a high-level university with Chinese characteristics. Throughout its 120 year history, Zhejiang University has always adhered to the fine tradition of "seeking truth and innovation" as its motto, taking the world as its own responsibility and truth as its basis. Gradually, it has formed the common values of "diligent learning, moral cultivation, discernment, and steadfastness" among the people of Zhejiang University, as well as the spirit of "embracing rivers, inspiring truth and virtue, advancing the people, and building our country".

1Furnace shell:

It is a cylindrical body made of welded steel and steel plates. The furnace shell has the required rigidity and strength for normal operation of the furnace body. One side wall of the furnace shell is equipped with a seat hole for the heating element power outlet rod and a protective cover. The surface of the furnace shell is painted according to the user's instructions.

2Furnace lining:

Adopting brick masonry or ceramic fiber composite lining structure; All the circumferential side walls of the furnace are made of lightweight refractory bricks, and aluminum silicate cotton is used for insulation between the heating chamber and the furnace shell,To reduce heat loss (the surface temperature of the furnace body meets national standards). Using high-temperature resistant resistance wire heating, there is a safety exit at the bottom of the furnace side, and a rotatable circular furnace cover is installed on the top of the furnace; The furnace bottom is made of lightweight bricks and heavy brick concrete masonry. The furnace lining has the advantages of good insulation effect, energy saving, good structural strength, light weight of the furnace body, and long service life.

3Electric heating element:

Using high-temperature resistance wire. Wrap it into a spiral shape, and place the wound resistance wire in layers inside the wire support brick; The resistance wire is divided inside the furnace1District layout, each division3Phase; The ceramic fiber composite lining is heated by high-temperature resistance strips, which are installed in layers on the fiber lining.

4. Crucible

Users can bring their own crucibles and design the size of the electric furnace according to the crucible size.

5Furnace cover

Manually open the furnace cover, with a guide on one side of the cover,The furnace cover opens upwards;

6Electrical control:

The main circuit control adopts high-power AC contactors or thyristors, equipped with1Only intelligent temperature control meter, total1Zone control can achieve power adjustment and effectively control temperature during the working process, which is one of the very advantageous measures for maintaining temperature uniformity..

7.The control system is advanced and reliable, and is equipped with safety interlock devices such as overheating and leakage alarms. The smelting furnace group is equipped with a central control cabinet for centralized control and safe and convenient operation.

8.The control system is equipped with a microcomputer time controller, which can freely set the opening and closing time of the furnace, thus avoiding manual opening.
