Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) is located in Zhengzhou City, Henan Province, Zhengzhou Xinmi shangzhuang Industrial Development Zone, Contact: Cheng Haitao followed for the manufacture of steam boilers, furnace smelting furnace windows and mechanical parts. Clay and alkaline siliceous refractory products can be processed into alumina bricks MgO-C bricks acid, can also be replaced by acidic refractories manufacturing all kinds of low-cost, uniform thickness of the insulating material. Physical characteristics: Refractories is a layered water containing silicate minerals, many types of basic refractories has a unique acid, alkali, chemical stability, but also has good insulation and heat resistance, non-flammable, corrosion protection. Electronic industry is the use of electronic ceramics kiln ceramic materials electrical, thermal, magnetic, gas, power, infrared and other unique properties of ceramics, its varieties, including electronic substrate, Manifold Seal, resistor high MgO-C Original radio frequency aluminum brick acid brick, capacitors, inductors and filters, etc., various types of sensors, transducers, pressure overcurrent protection devices, batteries, magnetic devices. In the electronic ceramics production process, sintering is a very important process, carried out in the thermal equipment ---- kiln. Sintered ceramic many types of electronic devices carbon brick high alumina brick acid brick, there is no formation of a standardized and serialized, with a sintering furnace can be different electronic ceramic products, while the same product can also be fired at different kiln . Sintering equipment according to the operation can be divided into continuous and intermittent, while the heat source can be divided into the electric heat and flame type, but often the use of a resistive heating furnaces.
